Rainwater harvesting manual released in Nairobi, Kenya
Nairobi's deputy mayor, Charles Kiyo Muratha, released the publication
'A rainwater harvesting manual for Nairobi' at a meeting
held at National Museum of Kenya, on December 7, 2004. A model
rainwater harvesting project was also inaugurated at the venue
on the same day, followed by a seminar.
Centre for Science and Environment (CSE) has published the manual
in collaboration with RELMA
(Regional Land Management Unit) in ICRAF (International Centre
for Research in Agroforestry), Nairobi. It is a compilation of simple
rainwater harvesting techniques suitable for urban areas and also
has case studies of successful initiatives from Nairobi, New Delhi
Kiyo Muratha, Deputy Mayor Nairobi (centre), and CSE's Sumita
Dasgupta (left) at the release function
the occasion, Sumita Dasgupta, Coordinator, Jal Swaraj Campaign,
CSE, spoke about the universality of water scarcity in urban areas.
She said that although Nairobi gets over 900 mm rainfall over nine
month every year; the city faces acute water shortage. Most of the
city's water supply sources are over 150 kilometres away.
Dasgupta admitted that the situation is no better in most Indian
cities. "But we have learnt how to manage the resources and
make use of the precious gift - rain," she said. The manual,
she added, is a guide to rainwater harvesting practices that can
be implemented easily.
Bashir Zaman, Deputy
Director General, ICRAF, stressed upon the urgency of preserving the
catchments for Nairobi's water supply system. He said that
the catchments are quite far from the city and are being threatened
by rapid erosion, deforestation and pollution. He suggested that a
plantation drive be undertaken to reduce soil erosion and increasing
the natural infiltration in the catchments.
Deputy mayor Muratha said: "Water is becoming increasingly
scarce in Nairobi. We need to take steps to popularise rainwater
harvesting to conserve this precious resource." He said that
the government has pledged to create a specific body to support
this movement. He exhorted the people of Nairobi to adopt rainwater
harvesting to ease the stress on the municipal supply and to ensure
year-round availability of safe water.
Addressing the large gathering, comprising engineers, architects,
planners, and representatives from NGOs, educational institutions,
government officials, researchers, journalists, and interested citizens
of Nairobi, Miambo Malesu, Regional Coordinator, RELMA, emphasised
the need for long-term collaboration with NGOs like CSE, which have
done pioneering work in the field of rainwater harvesting. He urged
those present to "water on the seed" by taking active interest
in the model rainwater harvesting project at the National Museum of
Model rainwater harvesting project at National Museum of Kenya
A model rainwater harvesting project got underway at the biodiversity
block of National Museum of Kenya, Nairobi, on December 7, 2004.
For Science And Environment (CSE) and Regional Land Management Unit
(RELMA), Nairobi, have jointly set up the project as part of an
effort to spearhead a rainwater harvesting movement in Kenya. Charles
Kiyo Muratha, Deputy Mayor of Nairobi, inaugurated the project.
National Museum of Kenya in Nairobi was selected because it:
Experts from CSE along with National museums of Kenya jointly inspected
the site and targeted the Biodiversity block as a model site for the
project. Salahuddin Saiphy, a CSE expert on rainwater harvesting,
designed the system. It was quite challenging to complete the construction
work with a short period. In order to achieve the target John Mbugua,
a Nakuru based contractor worked very hard with his team and Saiphy
supervised the implementation.
- gets a large number of visitors everyday
- is easily accessible
- had some of the required infrastructure
The basic objectives of the model project are:
The rainwater harvesting system was designed keeping in view the large
section of the society. The system not only collects rainwater for
non-potable purposes like cleaning, washing, gardening and use in
toilets but also for drinking purposes from KWS Strong room's rooftop
covered with galvanised iron sheets. The concept of recharge well
was also being introduced for groundwater recharge for the first time
in eastern Africa.
- To act as a catalyst in spreading water literacy
- To reinstate and reaffirm the potential of rainwater harvesting
- To provide concrete evidence to citizens to indicate potential
of rainwater harvesting'
- To stabilise the imbalance between water supply and its demand
The rainwater harvesting system includes:
- A ferro-cement tank of 20,000 litre capacity - for non potable
- A recharge well - for groundwater recharge
- A PVC tank of 3500 litre capacity - for drinking purpose
Salahuddin Saiphy explaining the working of a rainwater system
work at the site also attracted a lot of visitors to the museum
and got briefing from the CSE expert about the project and its objective.
The ferro-cement tank was selected for storage because of its low
cost and simple technology. A ferro-cement tank can be easily constructed
by a mason and later maintained by the community. The tank is located
on the eastern corner of the building. The site selection for the
tank was done very carefully so that the gravity head can be used
to supply water to the toilets located downstream. The overflow
from the tank and rooftop water from a small portion of the building
is recharged into the ground with the help of a recharge well located
next to the tank. The recharge well is 1.5 m x 1.5 m x 2 m and provided
with a recharge bore 100 mm diameter and 10 m depth. A PVC tank
is also used to collect rainwater from the rooftop having galvanised
iron (GI) sheet, as rainwater collected from the sheets is considered
fit for drinking. A Nairobi-based PVC tank manufacturer, Kantainers,
donated the tank. Its objective was to create a model for small
household, which can store rainwater in tanks and use it during
the dry spell for drinking and cooking requirements.
The site was visited by a number of people including deputy mayor,
deputy DG, ICRAF, Principal, University of Nairobi, representatives
from various NGO, engineers, students and individuals. Explaining
the working of the system, Saiphy said that the storage in ferro-cement
tank is very cost effective and involves very simple technology
that can be implemented by a mason. "We have used locally available
material and manpower," said Saiphy. It was highly appreciated
by visitors and recharge well was of much interest for them as it
was a new technique introduced for the first time in Nairobi
Seminar on Rainwater Harvesting
A seminar on rainwater harvesting was also organised as part of
the event comprising the release of a manual and the inauguration
of a model rainwater harvesting project in the National Museum of
A large largely number engineers, university students, and interested
individuals attended it. Orodi Odhiambo, lecturer, Department of
Environment and Biosystems Engineering, University of Nairobi, spoke
on potential of rainwater harvesting in Nairobi. He said that if
done on large scale, it can solve the water problems of the city.
William Wambugu, manager, Botanical gardens, National Museums of
Kenya also shared his experiences.
Salahuddin Saiphy, a rainwater harvesting expert from CSE, made
an audio-visual presentation during the seminar. He said that the
purpose of rainwater harvesting is not merely to store rainwater
for direct use, but also to recharge groundwater.
Ground water recharge is an effective tool to arrest the sharply
declining water table in the area. He also shared the experiences
of rigorous monitoring of CSE"s rainwater harvesting projects
in Delhi and confirmed that most of the projects have experienced
a remarkable rise in water table after rainwater harvesting or check
the sharply declining water levels. He elaborated the concept and
principles of rainwater harvesting focusing both on storage as well
as groundwater recharge. He also unveiled the success stories from
Mumbai and Delhi highlighting the issues related to implementation,
maintenance and monitoring.
The seminar ended with a lively discussion. The number and variety
of the questions posed by the participants revealed their interest
and curiosity. Majority of the queries were related to the water
quality, campaign and CSE's impact on policy makers. There were
few questions regarding groundwater recharge technique also as it
was a new concept and being introduced for the first time in Nairobi.
Salahuddin Saiphy and Sumita Dasgupta jointly answered the questions.

Lecture on Rainwater Harvesting- Experiences from India at University
On the invitation
from University of Nairobi, on December 8th 2004, Salahuddin
Saiphy from Centre for Science and Environment delivered a lecture
at University of Nairobi. The lecture was focused on principles and
techniques of rainwater harvesting with case studies from India.
The university officials present in the seminar during the Rainwater
Harvesting Manual release function at National Museums of Kenya were
so influenced by CSE staff's presentation that the representatives
of the Department of Environment and Biosystems Engineering met him
personally and invited to deliver a lecture for its faculties and
students. Salahuddin Saiphy of JalSwaraj Camapign, CSE spoke at a
length about the concept, principles and different techniques of rainwater
harvesting. He nicely used the model rainwater harvesting projects
in Delhi to detail the different techniques of RWH. He also unveiled
the results of CSE monitoring in model projects to confirm the potential
of rainwater harvesting. He also screened the 90 seconds public service
advertisement on rainwater harvesting produced by CSE to sensitise
the participants. Cheering faces of the participants validated that
they really enjoyed it. Many of the participants requested for a copy
of the presentation and film and looking at the interest a copy was
given so that it can be used for imparting knowledge to the peoples
who could not attend the workshop.

Large turnout at workshop on wastewater management
A two-day workshop on Decentralised Wastewater Treatment Systems
(DEWATS) held in New Delhi on November 5 and 6, 2004 drew an enthusiastic
response from various quarters.
large number of architects, engineers, representatives of local
NGOs, officials from government agencies like INTCAH, CGWB, DJB,
HUDCO, DDA and institutions like SPA, IIT Delhi as well as industries
were among the participants.
The event, which was held at Indian Habitat Centre, New Delhi, was
jointly organised by the Centre for Science and Environment (CSE)
and Pondicherry-based NGO, Auroville Centre for Scientific Research
(CSR). The workshop was sponsored by European Union, Borda - Dewats
In his keynote address, Sunita Narain, director, CSE, highlighted
the need for decentralised wastewater management instead of centralised
treatment systems. She highlighted how Delhi, in spite of having
maximum number of treatment plants, could not clean up the Yamuna.
The CSE director also released a film on DEWATS produced by CSR.
The film explains how the DEWATS system works with the help of animations
and case studies.
After the inauguration function, Pedro Kraemer, coordinator, FEDINA
- BORDA spoke about their campaigns to spread the concept of decentralised
wastewater management systems. Kraemer said that out of 2,902 big
and small cities in India, 93 per cent of do not have sewage treatment
plants. And the plants in the few cities that have them are not
up to the mark.
In the technical session, Tency Beatens from CSR shared his experience
on wastewater management in Auroville. He said that a lot of effort
had gone in making the plants effective so that they can fit in
the urban scenario.
A technical presentation on Total Water Management then followed.
Lata Raman from Inspiration, a Kerala-based NGO, conducted the session.
Raman explained how they had incorporated rainwater harvesting and
wastewater management using DEWATS through case studies from Kerala
Durga Venkateswami and Kiran Vaghela from Hunna Shaala, a Gujarat-based
NGO, gave a joint presentation. They explained how DEWATS can be
used for treating wastewater at community level through proper planning.
The highlight of the first day's presentation was Dr Lucas Dengal's
speech, in which he spoke about a different technology, Effective
Microorganisms. He explained how the microorganisms derived from
molasses could be utilised for treating wastewater.
The second day of the workshop began with a presentation by Pedro
Kraemer, in his presentation he explained in detail to the architects
and engineer how to design a decentralised wastewater treatment
system. He explained about various designing parameters, components
and its implementation methodology and monitoring aspects.
After this presentation, the participants were divided into groups.
The groups were given basic inputs about CSE's new building and
were asked to come up with a wastewater treatment plant design.
This was a challenging job for the participants since the space
available to install the system was very limited. But the groups
presented their ideas and designs, which clearly showed that they
had got the basics right.

Paryavaran Sammelan vows to protect waterbodies
On August 29, 2004, Jeevan Surabhi Sewa Sansthan and Prakriti
Bachao Andolan, Baghpat based NGOs jointly organized a Payavaran
Sammelan (meeting on environment) was organised in Khekda in Baghpat
district of Uttar Pradesh. The meeting was attended by Sarpanchs
from different villages, local leaders, senior citizens and students.
The objective was to sensitize the villagers.
Baghpat, once dotted with numerous waterbodies is heading towards
a water crisis. The district has already been declared a dark zone
and the waterbodies are being heavily encroached. During his speech,
Omveer Tomar, Director, Jeevan Surabhi Sewa Sansthan appealed the
citizens to maintain and protect the water bodies and free them
from encroachments. He also urged the local administration and judiciary
to be more proactive when it comes to protecting the waterbodies.
Chaudhary Noor Hasan, Sarpanch of Ratol a village in Baghpat, during
his speech recollected that the area used to be one of the largest
exporters of Ratol, a special variety of mangoes. Absence of desired
soil moisture has resulted in the poor yield of mangoes, which has
resulted in the decline in the mango orchards. Besides this, irrigation
mostly from groundwater has become costlier due to steep decline
in water levels. He also insisted on the tree plantation as the
number of tree is sharply declining in the area.
The CSE staffer, highlighted the ironical situation that the country
faces-droughts and floods. He called upon the audience to manage
water resources efficiently. He also outlined the importance of
traditional water harvesting practices in water management. The
importance of conserving existing water bodies and other groundwater
resources were also highlighted. He opined that rainwater harvesting
is a simple yet effective technique to replenish our water resources.
The meeting ended with a resolution to "conserve the existing
water bodies, construct new waterbodies in wastelands and increase
the vegetation in the area" so as to preserve the natural resources.

Harvesting (RWH) techniques at its Tughlakabad office on 18th august
2004. The objective of the training was to impart the training to
the real implementers of RWH structures and to generate the resource
base in the city.
Full day training programme was divided into two sessions- theoretical
and practical.. During the theoretical session Sumita Dasgupta,
Coordinator Jal Swaraj spoke about CSE's campaign. CSE staffer outlined
the griming water scarcity in most of Indian citied because of negligence
of traditional water harvesting practices and uncontrolled use of
water resources. They were not only taught the concept, principles
of RWH but also how to design the structures. Some tips for economical
and good quality construction were also shared with them.
During the second session- practical session, the participants were
asked to plan a rainwater harvesting scheme for a given site plan.
All participants made a scheme of RWH. Some of the participants
presented their designs and actively participated in the discussion.
"Jal Yodha" 22 minutes long film on water was also screened
at the occasion.
tips on rainwater harvesting
A seminar on rainwater harvesting
was organised in Kolkata, West Bengal,
on August 10, 2004. Experts from Centre for Science and Environment
were invited to speak on the potential of harvesting rain to address
the water crisis in the city.

urgency of water management and scope of rainwater harvesting in
griming water situation in the country left participants in a shock.
Laws and legislations in different cities like Delhi, Chennai, Indore,
Kanpur, Mumbai and Bangalore were discussed. Engineers were not
only given the introduction of basics and principals of rainwater
harvesting but also exposed to planning and designing aspects of
rainwater harvesting structures in detail. Experiences from the
CSE's Model rainwater harvesting projects were also shared with
During the second session- practical session participants were shown
the rainwater harvesting system of CSE's building and later Jamia
Hamdard University. There not only they saw different RWH structure
but also interacted with the host of the project, Mr Ahmad Ali,
Executive Engineer, Jamia Hamdard University.
While coming back to the class rooms they were asked to design RWH
system in a given site plan. All of them calculated total annual
RWH potential of the site and designed the scheme. Few participants
also made presentation of their designs.
The programme ended up with the feedback session and Rustam Vania,
Co-ordinator, Environment Education Unit distributed certificates
to all participants.
Training Programme for plumbers
Plumbers, masons and contractors were trained by CSE staffers in
Hotel Bliss, Kanpur on August 3, 2004. The objective of the program
was to equip the plumber with the technology of rainwater harvesting
and prepare them for implementation. It was a day long training
programme, divided into two sessions- theoretical and practical
session. About 35 plumbers, masons attended the program.
During the theoretical session, Salahuddin Saiphy and R K Srinivasan
from Jal Swaraj Campaign, CSE briefed about the griming situation
of water in major Indian cities including Kanpur. In Kanpur, deteriorating
water quality and declining water table is the major concern as
far as the water is concerned. The basics and principals of rainwater
harvesting were elaborated to the participants in detail. Planning
and designing aspects were also introduced to them.
During the practical session, the participants were taken to the
terrace of the hotel where they measured the dimensions of the building
and demarcated the location of rainwater pipes on the site plan.
Later they themselves calculated the annual water harvesting potential
of the site and designed the rainwater harvesting scheme. Group
leaders also presented their designs and thorough discussion among
the participants and trainers resulted in a cost effective and suitable
"Boond- Boond Se Ghat Bhare", a film on traditional water
harvesting practices and 90 seconds public service advertisement
on rainwater harvesting were also screened during the event and

Training Programme for plumbers
On August 2, 2004 a training program for plumbers and masons was
organised in Shipra Hotel, Ghaziabad. The objective of the program
was to impart training on the basics and design aspects of rainwater
harvesting and to generate the resource base in implementation sector.
The day long training programme was divided into two sessions- theoretical
session and practical session. About 54 participants attended the
program which includes plumbers, masons, tube well drillers and
During the theoretical session, Salahuddin Saiphy from Jal Swaraj
Campaign, CSE outlined the national water scenario focusing on major
Indian cities. The widening demand and supply gap in almost every
city and increasing dependence on groundwater resources was elaborated
in detail. R K Srinivasan, Dy. Coordinator Natural Resource management
Unit, CSE not only taught basics and principals of rainwater harvesting
but also shared experiences from the model rainwater harvesting
How to plan and design rainwater harvesting structures in a building
were elaborated in detail by Salahuddin Saiphy. Specifications for
making the structures and the precautions to be taken during the
implementation were also discussed in detail.
During the second session- practical session, the participants were
taken to the terrace of the hotel. The participants measured the
dimensions of the building and demarcated the location of rainwater
pipes and bore well on the site plan. All participants calculated
the annual water harvesting potential of the site and designed the
rainwater harvesting scheme. Some of the plumbers also presented
their designs and a very interactive session took place when many
plumbers gave their inputs and suggestions for improving the structures.
Responding to a question put by a plumber, it was suggested that
any kind of contaminated water should not be used for ground water
recharge because that may lead to groundwater pollution in long
term. "Jal Yodha", a film on traditional water harvesting
practices in different parts of India was also shown during the

Awareness programme on Rainwater Harvesting
On July 14, 2004, an awareness programme on rainwater harvesting
was organised for PVC pipe manufacturers of North India at International
Trade Centre, New Delhi.
On this occasion CSE staffers made a presentation on rainwater
harvesting. The presentation started with screening the 90 seconds
Public Service Advertisement on rainwater harvesting, which was
highly appreciated by the audiences and helped a lot to motivate
them. The focus of the presentation was "scope of rainwater
harvesting and its different techniques". Participants were
briefed about the concepts and principles, of rainwater harvesting.
Results of the rigorous monitoring in CSE's model rainwater harvesting
projects were also shared with the participants.
Awareness programme for school children
CSE conducted a lecture on urban rainwater harvesting on July 23,
2004 at Springdales School, Dhaula Kuan. This school has three rainwater
harvesting structures. CSE had provided the designs for the structures.
About 200 students from various classes attended the programme that
began with the screening of a 90-second spot on rainwater harvesting
produced by CSE. Thereafter, the children were explained the importance
of water conservation. The students were also briefed about the water
crisis situation in Delhi and the importance of rainwater harvesting
in solving the crisis. A special screening of the film Water Works
India: Four Engineers and a Manager was also organised.
State level media seminar on rainwater
A one-day state level media seminar was organised at Thiruvananthapuram
on June 22, 2004 by the Government of Kerala to initiate a statewide
campaign- cum- programme on rainwater harvesting. Jalanidhi, a World
Bank aided project of Govt of Kerala and by the Press Club of Thiruvananthapuram
played a key role in organising the seminar. Mediapersons from several
parts of Kerala attended the workshop.
Narain, director, CSE inaugurated the seminar. In her keynote
address, she stressed the need for water management in a state like
Kerala. The CSE director said that the focus should be on reviving
the traditional practices like open well and talabs (ponds),
which have been the lifeline for Kerala for many centuries. She
stressed the importance of having a decentralised water supply system
by reviving the open well culture through rainwater harvesting -
which is a cost-effective and sustainable solution - rather than
depending on the pipe line project which is not sustainable. In
her speech, she asked journalists to constantly write about water
and water-related issues, rather than writing about it during the
peak crisis time.
The seminar was also addressed by many experts like Shree Padre,
who spoke about simple water harvesting techniques that he practised
in villages of Karnataka and Kerala. Experts from CSE also explained
the various techniques of rainwater harvesting practises all over
The seminar concluded with the valedictory function, in which T
M Jacob, minister of water resources, Kerala, spoke about efforts
made by the government through Jalanidhi. He said that though Kerala
has over 40 rivers, the volume of water is only 30 per cent compared
to Godavari river. He said that the rivers drain all the rainwater
to the sea and this leads to the water crisis. Rainwater harvesting,
he said, could help in solving the state's water woes.
Environmental awareness programme
CSE participated in the Kerala government's Environmental Awareness
Programme in Kerala schools in New Delhi. During the week-long festival
experts from CSE delivered lectures in the schools at Canning Road

water levels and to recongnise the fact that there is an urgent need
to initiate rainwater harvesting projects in each colony at community
During his presentation, Salahuddin Saiphy of CSEs Jal Swaraj
Campaign outlined the water stress in the area and the national perspective.
He briefed the concept, principles and different techniques of rainwater
harvesting. He also unveiled the results of monitoring of CSEs
model rainwater harvesting projects and stressed that the community
efforts definitely pay off in the long term as a result of rise in
water levels in the area. He quoted the case study of Panchshila Park
colony, which stands out as an ideal model for the group houses for
rainwater harvesting in Delhi. He stressed the need for community-based
rainwater harvesting that costs less to implement than individual
RWH initiatives and benefits the entire community in a given area.
The interactive session at the end of the meeting was gripping, and
several queries raised by audiences were addressed. Most of residents
desired the financial assistance from the government to implement
rainwater harvesting on large scale but many of them shown keen interest
to adopt it at individual level, in absence of any support.
Network Meeting II, maintenance
and monitoring of rainwater harvesting structures
Centre for Science and Environment organised a Networking Meeting
of rainwater harvesters on June 15, 2004 at India Habitat Centre.
The objective of the workshop was to tell the practitioners how to

harvesting systems for the administrative block and the factory
guest house. The excited participants braved heavy rains to make
field observations. Later, both the group presented their designs.
The flaws in the designs were rectified during the discussion.
The authorities decided to take up rainwater harvesting system in
as a model project and resolved to complete the project before monsoon.
Participants also promised to actively participate in water conservation
drive not only in the plant but at their community. The authorities
also promised to start a water audit in the plant to cut down their
water requirements from 300 kl per day to 250 kl during the first
The training programme was beneficial for SRF Polymers Ltd as its
new plant is coming up in Indore, a high water-scarcity area. Rainwater
harvesting has been made mandatory in Indore. Some of the trainees
from the Kashipur unit will be transferred to Indore shortly. These
trainees will not only implement rainwater harvesting system there
but will also be able to maintain and monitor the structures efficiently.

Awareness programme on rainwater harvesting at Jamshedpur
CSE in collaboration with Tata Iron and Steel Company Limited (TISCO)
organised workshops, seminars and awareness programmes on rainwater
harvesting in rural areas as well as rural and urban areas of Jamshedpur
to spread the concept of rainwater harvesting between April 5-10,
Since the Jamshedpur possess a poor ground water potential the city
mainly depends on Subarnarekha, which is more or less an open sewage
drain. According to R P Sharma, Chief, Environment & Occupational
Health, the river cannot be a dependable source since its pollution
level is increasing day by day. The another water source is Chandela
lake but Tata has to pay Rs 7 crore for fetching water from this water
body and this amount may increase in future, so rainwater harvesting
will be viable option in Jamshedpur, since the city gets double the
rain what Delhi gets.
The first awareness workshop was conducted on April 8, 2004 for villagers
in Lupungdih, Lohavasa, East Singbhum where CSE experts informed the
villagers about the grim situation of water throughout the country
followed by the local problems such as the drying up of wells, tubewells,
pond, lakes and even river in summers. He insisted that rainwater
harvesting structures can be constructed in rural areas as well as
in urban areas. He spoke about the importance of community managing
the water resource with case study from Rajasthan and Maharashtra.
Responding to a query on why most ponds do not retain water till summer,
he explained that the site selection and regional topography is the
During the discussion, Madan Mahto, a farmer, explained how he grew
vegetables during the dry season: he has constructed a few bund in
the nullah near his field. This not only left some water upstream
but also allowed moisture downstream as a result of seepage.
CSE experts also answered queries from villagers during the discussion.
Workshop for students and teachers at Jamshedpur
A workshop for school teachers and students from various school under
TISCO was conducted on April 9, 2004 at KMPM Inter college, Jamshedpur.
Screening of a 90 second public services advertisement on rainwater
harvesting at the onset was widely appreciated by the participants.
During the workshop, the teachers and students were informed about
the water crisis in various parts of the country in general and Jamshedpur
in particular. The role of rainwater harvesting in solving the crisis
was also discussed. Concepts and principles of rainwater harvesting
was explained and the principles of traditional rainwater harvesting
techniques were also discussed. Experts also detailed the principles
of designing rainwater harvesting structures. They were informed about
various water harvesting technologies and different kind of structures.
Experiences with CSE's model rainwater harvesting projects were also
shared with the participants. The session concluded with the screening
of the film, The Secrets of Thar Desert.
Interactive workshop on water conservation at National Institute
of Hydrology, Roorkee
On April 13-14, 2004, National Institute of Hydrology (NIH) organised
a two day Interactive workshop on Water Conservation at Indian Institute
of Technology, Roorkee. Around 50 participants from 15 NGOs and different
government departments attended the workshop. About 15 presentations
on different issues pertaining to water conservation; rainwater harvesting
and watershed management spread over six sessions were organised.
K D Sharma, director, NIH outlined the water scarcity all over country
in spite of good monsoon and disparities in water quantity and quality.
He also outlined the role of NGOs, government and the common man in
the struggle against the water problems in present context. V C Goyal,
organising secretary, told that the water crisis is taking the shape
of mini civil war. He urged on the need of water movement that make
use of the traditional knowledge and scientific approach.
Delivering the inaugural address, Amar Singh Faroda, agricultural
scientist, said that there are two ways to conserve water. The first
is to conserve at resource level and second at utilisation level.
He said that both Jaisalmer in Rajasthan, which is gets about 100
mm of rainfall and Cherapunji in Meghalaya, which gets around 11,000
mm of rainfall, have water problems. Jaismand lake in Udaipur has
dried up for the first time in 300 years, he informed. Faroda said
that earlier, people of Jaisalmer and Barmer used a coat during bath
and collected the used water in a pot and used it later for washing.
Sushma Singh, additional secretary, ministry of water resources, said
that although water is a renewable resource, its availability is finite
and should not be taken for granted.
M Mehta from Central Ground Water Authority said that at present,
310 blocks in 40 districts of 16 states were over-exploiting water
resources. This has led to a drop of more than four metres in the
ground water levels.
A member of CSE's Jal Swaraj Campaign made a presentation on urban
water crisis and related issues like water availability, distribution,
pricing, sewage treatment and deteriorating quality. Concepts, principles
and different techniques of rainwater harvesting were explained and

After setting in motion the urban rainwater campaign in Mumbai by
launching the region-specific edition of CSE's popular Water Harvesting
Manual in Marathi and English languages, CSE participated in a workshop
for professionals that was organised by Asian Paints in Mumbai on
February 17, 2004. Mumbai Municipal Corporation Commmissioner, Karun
Srivastava, inaugrated the workshop and stressed the need for water
conservation in Mumbai. Sumita Dasgupta, Coordinator of the Jal Swaraj
Campaign provided a broader picture of the water situation in Maharastra
and in Mumbai. Several RWH practitioners, including Rajender Singh
of Tarun Bharat Sangh and K R Gopinath of KRG Rainwater Harvesting
Foundation, Chennai attended the Mumbai workshop.
Water conservation and rainwater harvesting
one-day workshop on water conservation and rainwater harvesting was
organised by the West Bengal Pollution Control Board (WBPC) on January
16, 2004 in Kolkata. In his welcome address, Dr S K Sarkar, Member
Secretary, WBPC, said that water harvesting was a traditional practice
in India and should be revived. Sukumar Das, Principal Secretary,
State Water Investigation Department, said that not all the blocks
in West Bengal are water bearing. Of the 321 blocks, only 269 blocks
have water potential; the water potential in the remaining blocks
was less due to the presence of laterite, crystalline terrain and
salinity, which severely limits the sources for future extraction
of water. To illustrate, he claimed the water level has fallen from
14m below ground level (bgl) in 1991 to 18m bgl in 2001 in the Park
Circus area. He said the water requirement in 2000 which was around
10.85 million hectare meter (mhm) is projected to rise to 20 million
hectare meter by 2050. The domestic and drinking water requirements
will rise from 0.26 mhm to 0.40 mhm by 2050, making the future of
water supply uncertain.
B K Basu, Chief Engineer, WBPCB, said that considering the unplanned
urbanization in future, WBPCB has issued a " Direction"
date 19th December, 2003. According to this Direction, Municipal Corporations,
Municipalities, Zilla Parishads, Panchayat Samities and Panchayats
will be discouraged from sanctioning any building plan of a housing
complex having 100 flats or more, or those with a super built up area
of 60,000 sq.ft or more, without the prior environmental clearance,
i.e., 'Consent to Establish' issued by the State Board. Subhas Dutta,
CGWB Scientist (Eastern Region), talked about the hydro-geology of
West Bengal and Kolkata. He said that along with water, sand is also
being pumped out. This is due to the unscientific construction of
tubewells. If unchecked, such sand pumping may lead to land subsidence
also. He said that CGWB monitors the water level four times a year,
and the post-monsoon water level is showing a steady decline. From
1987 to 2002, the post-monsoon water level has declined in the Salt
Lake City region. He further said that in Kolkata, the freshwater
aquifer is sandwiched between saline and brackish water-bearing aquifers.
So excess pumping of fresh water will lead to brackish water contaminating
the fresh water aquifers. He said that in South Kolkata, the freshwater
aquifer now extends to between 50 to 100m bgl. Here the freshwater
is floating above the saline water, so excess pumping may lead to
the up coning of saline water.
He also warned that the natural recharge from rainwater is not possible
in Kolkata due to the presence of an impermeable clay layer above
the permeable sand formation. He said that in North Kolkata, freshwater
exists from 40m to 100 m below ground level (bgl), while in Central
and South Kolkata, the level is between 20 to 150m. He says the water
level has dipped from 5 to 9m bgl in Central Kolkata in 2003. A member
of CSE's Jal Swaraj Campaign outlined existing legislations in various
cities in India. He mentioned how the latest ordinance in Chennai
and its followup activities had led to the successful implementation
of RWH in individual houses. He also quoted the case of Delhi where
CGWA has come up with several implementation deadlines.
were also taken to two sites in Kolkata, Poura Bhawan in the Bidhanagar
Municipality office complex, and Bidhannagar Government College, where
they were shown rainwater harvesting structures. In these two buildings
rainwater is stored in a ferro-cement tank of 12,000 liters and the
cost of the each tank is approximately Rs. 22,000.
The site visits were followed by a technical session, in which Dr
T S Bandopadhyay, Director, IWMED, spoke about rainwater harvesting
Exhibitions organised by CSE in New Delhi
a part of its Jal Swaraj Campaign, CSE organised two exhibitions at
Maurya Sherton and at the Indian International Centre (IIC). The two-day
exhibition at Maurya Sherton was held from Febraury 7-8, 2004. The
IIC exhibition was a part of water festival organised by IIC from
February 17 to 22, 2004. CSE participated in both these events by
displaying posters on urban RWH strategies and issues. The poster
series also outlined various methods and techniques of urban rainwater
harvesting. The posters also showcased CSE's model projects. A model
showing the water harvesting system installed in the CSE building
attracted the general public who visited the stall. CSE's influential
publications on water management and RWH were also displayed at the
Book release and workshop on rural water harvesting
The Hindi edition of the Urban Water Harvesting Manual published
by the Centre for Science and Environment was released by Tarun Bharat
Sangh's Rajendra Singh on February 17, 2004 at a workshop jointly
organised by India Soya Foundation and Rotary Club of Indore city.
The workshop was organised to educate people regarding the alarming
water situation in the region and to motivate them to adopt region-specific
water harvesting techniques and effective water management strategies
to overcome the crisis.In the welcome address O P Goyal, of India
Soya Foudation spoke about the growing water crisis in Malwa reagion
of Madhya Pradesh and the urgent need to restore the deteriorating
situation. In the inaugural address CSE staffer spoke on the current
water (mis)management practices and the increasing levels of dependence
on government. The presentation also highlighted the potential of
traditional water management techniques and its relevance in today's
water stress situation.
Rajender Singh in his speech insisted on mobilising people creating
awareness in the rural areas to conserve rainwater in order to save
the region from becoming a dry zone.
In the workshop Laxman Singh from Jaipur, GT Bhimte from Indore, Vijay
Kedia from Aurangabad and CSE staffer shared various local and cost
effective rural rainwater harvesting techniques with the participants.
The workshop was attended by farmers, village pradhans, government
officials, local citizens and students.
Lecture on RWH for ECO CLUB schools in New
CSE delivered a lecture on RWH in a programme organised by The Shri
Ram School, Vasant Vihar, New Delhi, (an Eco Club lead school identified
by Government of Delhi) on February 17, 2004. The target group included
teachers and students from 20 government schools of Delhi.
CSE's lecture focused primarily on water management and rainwater
harvesting. The talk outlined the water scarcity in India and reasons
of scarcity amidst plentiful rains. Uncontrolled exploitation, rampant
usage, polluted water resources are not new in most of the urban areas.
Concepts and principles of RWH was explained by narrating the rich
traditions of rainwater harvesting that existed in India right from
the Indus valley civilization. Starkling experiences
from CSE's Model RWH were also shared during the occasion.
Apart from CSE staffer Manoj Dabbas from (ATTREE) , Vimlendu Jha (We
For Yamuna) spoke about the environmental aspects that teachers must
be conveying to their students while interacting with students.
Anil Kumar from Centre for Environment Education also spoke about
the magnitude of waste water generated in an urban environment and
need to manage it.
