Performance evaluation of percolation ponds for artificial recharge - A research report by National Institute of Hydrology

The study assesses the quantum of seepage to the aquifers through percolation ponds and establishes their zone of influence, and based on these, correlates the quantum of seepage to the total storage loss in the pond. The assessment of the benefits of the ponds, in terms of artificial recharge to the aquifers is done through an intensive study of two percolation ponds in Tamil Nadu.

A percolation pond is a small water harvesting structure, constructed across a natural stream or water course to harvest and impound the runoff from the catchments for a longer time, to facilitate vertical and lateral percolation of impounded water into the soil substrata, thereby recharging groundwater storage in the zone of influence of the pond.Read More

Implementation of SCS model in Dudhnai watershed - A research report by National Institute of Hydrology

The study applies the methodology developed by United States Department of Agriculture’s (USDA), Soil Conservation Services (SCS) for the nine subwatersheds of the representative Dudhnai basin in Assam & Meghalaya and estimates the runoff volume on a daily basis for the period 1986-1991. The method is widely adopted for the estimation of runoff from rainfall depths and takes into account the important physical aspects of a basin on which runoff depends such as land-use, hydrological soil cover and antecedent moisture condition.Read More

Water conservation efforts of ITC Limited - PSPD Unit - Kovai (Tamil Nadu)

This presentation describes the water conservation efforts made by ITC Limited,  PSPD unit, Kovai, Tamil Nadu. ITC's Kovai unit manufactures paperboard and specialty papers (PSPD). Investments of Rs 30 million in water conservation, Rs.500 million on energy conservation and Rs.150 million on waste utilization have helped this plant achieve many breakthroughs, among them zero effluent discharge and zero solid waste output. 100% of the fly ash from the boiler, sludge from the ETP & plastics from waste is recycled.Read More

The use of waste biomass as the main fuel for the boiler has reduced CO2 emissions by 96,000 tonnes per annum. Under the green belt development activities, vegetation has gone up from 20,000 trees in 2004-'05 to 80,500 in 2006-'07.
