Reverse osmosis plants for rural water treatment in Gujarat - A research paper by CAREWATER
Posted on 23 Mar, 2010 01:38 AMThis research paper attempts to understand and map the Reverse Osmosis (RO) phenomenon, a technology that is turning out to be an important solution for drinking water treatment in rural Gujarat. Treatment plants with capacity ranging from 10 litres per hour (lph) to 6000 lph are now supplying drinking water in several hundred villages of the state. Small sized plants with capacity < 20 lph are used by individual families whereas medium to large sized plants (>100 lph) are being used for public consumption.

Hydrogeological studies for improved groundwater management strategies in the dryland areas underlain by Deccan basalts - ACWADAM
Posted on 02 Mar, 2010 05:18 PM
This detailed hydro-geological action research study in ten villages of Eastern Purandar taluka in Pune district (which is classified as a dark zone due to excessive groundwater exploitation) gives a good picture of groundwater resources in the area, and complements it with allied information such as weather data, socio-economic details, thematic groundwater maps, aquifer information, groundwater usage and its recharge-discharge relationship in space-time. The study was undertaken by ACWADAM and GGP, with a purpose to provide a platform for implementing agencies for on-the-ground action towards better groundwater management practice through community based efforts, as well as to advocate the typology of groundwater problems, that require specific approaches for mitigation.
The starts with a basic introduction to the study area, objectives and methodology adopted, and is followed by sections on the accumulation and movement of groundwater and the situational base. These two sections have details about the drainage, geology and hydro-geology of the region, groundwater over-exploitation, groundwater salinity, community-based groundwater systems, groundwater characteristics, base flow in streams, water quality, weather, pumping tests, hydro-chemical characteristics, pollution indicators, socio-economic aspects, remote sensing maps and more.
The study recommends that to improve the groundwater situation in the area, new soil/water conservation structures be built in the upper reaches of the watershed, and focus for the existing soil/water conservation structures be on maintenance and repairs. It concludes with a list of specific action-recommendations based on three typologies - groundwater over-exploitation, inland groundwater salinity and community-based groundwater management.This detailed hydro-geological action research study in ten villages of Eastern Purandar taluka in Pune district (which is classified as a dark zone due to excessive groundwater exploitation) by ACWADAM gives a good picture of groundwater resources in the area, and complements it with allied information such as weather data, socio-economic details, thematic groundwater maps, aquifer information, groundwater usage and its recharge-discharge relationship in space-time.
Pollution of River Ganga, its control and preservation
Posted on 01 Mar, 2010 03:54 PMI recall the day two months before, when I had the opportunity to attend a seminar at the outskirt of Delhi. The hot topics, to be bothered and discussed in the gathering was: “Pollution of River Ganga & its Control and Preservation” (i.e. Ganga ka Pradushan … Ganga Bachao”).
And so, so early reached at the venue ignoring the shivering cold weather. However, it happened so, probably due to the chilly cold situations, that VIPs- honourable guests and invited respected audience reached one by one…. at last to conclude it to be ‘a late affair’!

Water contamination footprint- A paper by Chetan Pandit
Posted on 16 Feb, 2010 01:27 PMGuest post by Mr. Chetan Pandit who works for the Central Water Commission, Government of India
This blog is a condensed version of the paper published in the 3rd Round Table on Sustainable Consumption and Production, organized by the Ministry of Environment and Forests jointly with UNEP, at New Delhi on 11-12 Feb 2010. The views expressed in this article are author’s personal views, and are not to be taken as the views of his employers.
In any discussion about Sustainable Development (SD) the quantity of consumption is invariably the main concern. Perhaps this stems from the original definition of SD as the “Development that meets the needs of the present without compromising the ability of future generations to meet their own needs", which invokes the spectre of insufficient quantities of resources at some time in the future. This concern is invalid for water, because water is a dynamic and renewable resource. Every hydrologic year brings a fresh packet of water. There is no way to use in this year, the rainfall that is yet to occur in the next year, or next decade. Moreover, any unused water will flow away to the oceans. The storages capacities, whether in surface storages or in aquifer, are adequate for one year only, at the most a little carry over for the next year. With many basins already reaching “water stressed” status, the problem at hand is how to supply the needs of this year, and there is no question of storing the water for future generations. Thus, in the context of water, quantity of water used should not be the primary concern for SD.
