Meet the new harvesters!
CSE is extending technical guidance for urban
rainwater harvesting, as a part of its urban miscellaneous services. In large numbers
interested individuals and institutions approach us every friday. Significantly, most of
them have put our ideas into practice. Industries, hospitals and jails are the newest
members of our harvester's family, as they begin to understand rain. Let us meet them.

Harvesting system at Hero Honda |
HERO HONDA MOTORS LIMITED
By implementing rainwater harvesting system in two of their factories located in
Dharuhera and Gurgaon, Haryana, Hero Honda has set an example for others to follow. In
relative terms, although the automobile sector is not the largest consumer of water but
still 75 per cent of their requirements are met from groundwater sources.
CSE provided the designs. In Dharuhera, the rooftop water from the
administration, main factory, canteen and, R and D buildings is diverted to six recharge
wells through separate pipelines. In Gurgaon, roof runoff from canteen, SPD block, and new
engine plant buildings are diverted to four recharge wells of 2 x 3 meter (m) and a depth
of 30 m. In 2002, the work in both the units was undertaken by their engineering section
without disturbing the complex's landscape.

INDIAN SPINAL INJURIES CENTRE
|
The site plan |
While realising a rapid decline in the water tables, Indian Spinal Injuries
Centre, took up rainwater harvesting (RWH)system with CSE's technical assistance. In 2002,
the works were completed at a cost of Rs 50,000.
The runoff from the roof and surface is collected in a series of chambers
covered with perforated metal plates. The water is then diverted into three recharge
wells. The engineering unit of the hospital has executed the project. As the RWHsystem is
in place, extra care is given to keep the catchment clean.It has become a source of
inspiration for other hospitals in Delhi to follow.

TIHAR JAIL
|
At Tihar Jail |
One of the largest prisons of the world, covering an area of 400 acres has
installed rainwater harvesting system. Ward number 1 and 13 of jail number 4, were
undertaken with CSE's technical assistance. A New Delhi-based NGO Scope Plus, working in
Tihar, for past several years initiated the process with active support of the prison
authorities. Rs 20,000 was the implementation cost provided by Coco Cola. The prisoners
worked as labourers. Before the works actually started the prison officials and the
prisoners were sensitised about the significance of rainwater conservation through
workshops. Ward number 1 is in the low lying area with a flat roof. The roof and surface
runoff are diverted to a percolation pit. The roof outlets of ward number 13, is
inter-connected to a common point, filtered and recharged. This is an initiative worth
noting.

TEX CORP LIMITED
|
Harvesting plan of Tex Corp |
The zip manufacturing unit of Tex Corp limited at Gurgaon, has become water
savvy, by implementing the designs provided by CSE in 2002. The rooftop runoff from 4,000
square meters (sq m) (amounting to 20.77 lakh litres, annually) is passed through a series
of sand and pebble filtering chamber to two recharge borewells. Implemented at a cost of
Rs 5.5 lakhs, Tex Corp believes it will solve the problem of increasing salinity, while
meeting their daily needs.
