Percolation Pit is also like Rainwater Harvesting System A percolation pit, in its most low-tech form, is a simple hole dug into the ground. It facilitates groundwater recharge through infiltration of surface runoff into the soil or rock. Differences to contour trenches: Better water storage capability due to greater depth. Percolation tank is an artificially created surface water body, submerging in its reservoir a highly permeable land so that surface runoff is made to percolate and recharge the ground water storage. The percolation tanks are mostly earthen dams with masonry structure only for spillway. Percolation tank is an artificially created surface water body, submerging in its reservoir a highly permeable land so that surface runoff is made to percolate and recharge the ground water storage. Percolation tank should be constructed preferable on second to third order streams, located on highly fractured and weathered rocks which have lateral continuity down stream. The recharged area down stream should have sufficient number of wells and cultivable land to benefit from the augmented ground water. The size of percolation tank should be governed by percolation capacity of strata in the tank bed. Normally percolation tanks are designed for storage capacity of 0.1 to 0.5 MCM. It is necessary to design the tank to provide a ponded water column generally between 3 & 4.5 m. The percolation tanks are mostly earthen dams with masonry structure only for spillway. The purpose of the percolation tank is to recharge the ground water storage and hence seepage below the seat of the bed is permissible. for dams upto 4.5 m. height, cut off trenches are not necessary and keying and benching between the dam seat and the natural ground is sufficient.

Water audit is a systematic process of objectively obtaining a water balance by measuring flow of water from the site of water withdrawal or treatment, through the distribution system, and into areas where it is used and finally discharged. Conducting a water audit involves calculating water balance, water use and identifying ways for saving water. Water audit involves preliminary water survey and detailed water audit. Preliminary water survey is conducted to collect background information regarding plant activities, water consumption and water discharge pattern and water billing, rates and water cess. After the analysis of the secondary data collected from the industry, detailed water audit is conducted, which involves the following steps:  On site training and discussion with facility manager and personnel  Water system analysis  Quantification of baseline water map  Monitoring and measurements using pressure and flow meters and various other devices  Quantification of inefficiencies and leaks  Quantification of water quality loads and discharges  Quantification of variability in flows and quality parameters  Strategies for water treatment and reuse or direct use A detailed water balance is finally developed. Water quality requirement at various user areas is mapped, which helps in developing „recycle‟ and „reuse‟ opportunities. The detailed water audit report contains the following:  Water consumption and wastewater generation pattern  Specific water use and conservation  Complete water balance of the facility  Water saving opportunities  Method of implementing the proposals  Full description and figures  Investment required Industries can undertake following measures for water conservation:  Setting up of norms for water budgeting  Modernization of industrial process to reduce water consumption  Recycling water with a re-circulating cooling system  Ozonation cooling water approach which can result in five fold reduction in blow down when compared to traditional chemical treatment  Reduction in reuse of de-ionized water by eliminating some plenum flushes, converting from a continuous flow to an intermittent flow system and improving control on the use  Use of wastewater for use of gardening  Proper processing of effluents to adhere to the norms of disposal.

Earthen Pond An earthen pond is an artificial lake or pond created by shaping and building an earthen or dirt embankment around a depression or low-lying area. These ponds are commonly used for recreational or ornamental purposes and can also serve as water sources for livestock or irrigation. Regular Monitoring: Keep an eye on water levels. Debris Removal: Clean out leaves, branches, and other debris. Aquatic Vegetation Control: Manage plant growth. Long-Term Sustainability: With care, earthen ponds can thrive as safe habitats for both wildlife and humans

Water Conservation, Ground Water Rejuvenation and Development via Rainwater Management and Harvesting Rainwater through Ponds and Borewell Recharging Structures to Support Increasing Demand of Water for Daily usage for Domestic, Industrial and Agricultural purposes. Water Conservation and Harvesting Structures in Naturally Water Scarce Regions creates Geo-Hydrological Opportunity and Economic Viability. Ponds recharging structure, farm pond, stop Dam, and small pond etc. It is seen that different Geographical Location and unique Geophysical and Hydrological Nature and every situation needs to be addressed, separately, the groundwater recharge capacity of the varies regions may vary depending upon area specific geophysical nature of earth strata. Recharge Wells provide an opportunity to extract sub-surface flow of the region without exploiting the Groundwater reserve.
