Rainwater Harvesting


Overview

CSE started its work on water issues way back in the 80s, when it was becoming apparent that the water management paradigm based on exploitation of surface and groundwater resources even as it neglected capturing rain to recharge or for direct use would lead the country to a huge water crisis. CSE first focussed on pushing for policy reforms in the water sector to mainstream harvesting rainwater in both urban and rural areas.

Desperate for rains

Mumbai municipality to induce rains; activists call it a sham

torrential rains pounded Mumbai in the last week of June, but failed to help the city tide over the severe water shortage. The Municipal Corporation of Greater Mumbai is now making frantic efforts to ease the crisis. On July 15, its standing committee decided to induce artificial rains through cloud seeding.

RWH Project

Traditionally, water was seen as a responsibility of citizens and the community collectively took the responsibility of not only building but also of maintaining the water bodies. Since independence, the government has taken control over the water-bodies and water supply.

Components of Rainwater Harvesting system

A rainwater harvesting system comprises components of various stages - transporting rainwater through pipes or drains, filtration, and storage in tanks for reuse or recharge. The common components of a rainwater harvesting system involved in these stages are illustrated here.

Rain or no rain

Last fortnight a dominant image on TV screens was drought. This fortnight, vast parts of the country drowned in water. An uncertain, unpredictable and variable monsoon is still impacting us. Late rain has delayed or jeopardized sowing; or intense rain has thrown life asunder and flowed away rapidly, creating months of (future) scarcity. Regional variations are huge, too. So there is drought in otherwise moist northeast and in paddy-growing Punjab and Haryana. A different monsoon, perhaps signalling the climate-changing times ahead.

It’s raining GDP

This is the fortnight of India’s budget. Pink and white papers scurry around for comments on what the finance minister will do for India’s economy, completely missing the bigger questions. What will happen if the Indian monsoon fails—or fails in the critical period when farmers sow the kharif crop? What will happen if reservoirs—holding water for drinking or electricity—do not get their supply from the sky? Will we have water to drink in cities? Will we have water and power to operate industries?

Maintenance

Quality of stored water

To prevent leaves and debris from entering the system, mesh filters should be provided at the mouth of the drainpipe. Further, a first-flush device should be provided in the conduit before it connects to the storage container.
