Water suficient
People of Padmanabha Nagar (PN) in Adyar, a residential colony situated in coastal
track of Chennai city have effectively resolved their drinking water problem, by adopting
rainwater harvesting technique.

It all started in 2001, when Chennai was going
through a period of severe water scarcity. This colony of 65 individual houses, covering
an area of around three acres was also facing a problem due to seawater intrusion. The
state water supply was not only irregular but limited in quantity as well, thus compelling
people to buy water. The middle class residents of PN were spending about Rs 2,000
Rs 3,000 per month on water.
Venkatraman, president of PN welfare association,
decided to adopt the technique of rainwater harvesting in his colony. He was assisted by
Shekhar Raghavan, a Chennai-based rainwater harvesting facilitator. Venkatraman decided to
begin with his house. To demonstrate the benefits of this technique to other residents he
designed a diversion pipe (a four inch PVC pipe bend with a reducer of four inch to one
inch that can be fitted with any rooftop water downtake pipe of four inch diameter)
through which water can be diverted to any part of the house. Initially, to popularise
rainwater harvesting among the residents, he also announced a subsidy of Rs 250 for
feasibility study.
In 2001, when one night of rain filled the sumps
of 4,000 litre capacity with water, people started realising the potential of rainwater
harvesting. Today, 54 houses in PN are catching rain.
The designs used are simple. Venkataraman
explains, "Rooftop rainwater is diverted to sumps for direct usage". To reduce
the cost, pipes near the sump and dug wells are used.
Rainwater harvesting is also strengthening inter
community bonds in PN. As Venkatarman narrates, "When Seshadri, a PN resident decided
to go for water harvesting, he realised that his neighbour Krishnaswamy and
Afzals pipes runs near his dug well. Thus, it would be in everyones interest
to take collective action. Both of them not only agreed but also gave their financial
contribution for the project."It clearly shows that water knows no boundaries of
caste or religion it stays with people, who respects and conserves it.

Active campaigner
An IIT Professor from Chennai, MV Satyanarayana, is actively campaigning to popularise
rainwater harvesting particularly among the student community. His programme essentially
starts with a poster exhibition, followed by a presentation and discussion. So far, he has
made 12 presentations in and around Chennai city. Many people have contacted him to
implement rainwater harvesting systems in their residence. His services are free of cost.
Satyanarayana feels that "Though the awareness levels among the people has increased,
urbanities are still cynical about the entire concept of rainwater harvesting. |

Municipal
water bonds
Tamil Nadus Urban Development Department is
planning to introduce municipal water bonds to raise much needed funds to upgrade and
maintain the local infrastructural services, particularly in the water sector. This would
requires the citizens to pay the non-subsidised price for the services that they avail.The state government is thinking of floating these bonds
to fund a state level water and sanitation programme. In March, a multi-lateral lending
agency discussed its proposal of giving 50 per cent backing to the amount raised for these
municipal bonds, on some conditionalities. If the proposal is accepted by the state, the
escrow accounting system may also be introduced where the local bodies
can be asked to put a certain portion of the tax collected in separate account to meet any
repayment defaults. Administrators are considering it as a positive system that would
improve the credit ranking of these bonds.
The officials are banking on the changed attitude
of people for the success of this scheme. According to them, "People are willing to
pay user charges for good services. If the services rendered are improved, the collection
rates would also go up, which would positively enhance the financial viability of these
bonds." It is also believed that the most of the elected members of urban local
bodies who have retained their positions for the second time in the row, due to their own
individual creditability would play a significant role in popularising this concept
amongst people.
