Geophysical survey for Rainwater Harvesting, a number of years of experience and technical knowledge we are able to provide you the most suitable locations to drill a Borewell on your site. By using technically advanced equipment like Resistivity meters & Electromagnetic (EM) VLF instruments we provide high quality service with excellent execution. Before any Rainwater Harvesting System construction is done, we help you in identifying the nature of Soil Structure & what is the actual Depth to recharge Rainwater.

Roof Top Rain Water Harvesting What is Roof Top Rain Water Harvesting? Rooftop Rain Water Harvesting is the technique through which rain water is captured from the roof catchments and stored in reservoirs. Harvested rain water can be stored in sub-surface ground water reservoir by adopting artificial recharge techniques to meet the household needs through storage in tanks. The Main Objective of rooftop rain water harvesting is to make water available for future use. Capturing and storing rain water for use is particularly important in dryland, hilly, urban and coastal areas. In alluvial areas energy saving for 1m. rise in ground water level is around 0.40 kilo watt per hour. Need for Rooftop Rain Water Harvesting 1. To meet the ever increasing demand for water 2. To reduce the runoff which chokes storm drains 3. To avoid flooding of roads 4. To augment the ground water storage and control decline of water levels 5. To reduce ground water pollution 6. To improve the quality of ground water 7. To reduce the soil erosion 8. To supplement domestic water requirement during summer, drought etc. Advantages of Rain Water Harvesting 1. Provides self-sufficiency to your water supply 2. Reduces the cost for pumping of ground water 3. Provides high quality water, soft and low in minerals 4. Improves the quality of ground water through dilution when recharged to ground water 5. Reduces soil erosion in urban areas 6. The rooftop rain water harvesting is less expensive 7. Rainwater harvesting systems are simple which can be adopted by individuals 8. Rooftop rain water harvesting systems are easy to construct, operate and maintain 9. In hilly terrains, rain water harvesting is preferred 10. In saline or coastal areas, rain water provides good quality water and when recharged to ground water, it reduces salinity and also helps in maintaining balance between the fresh-saline water interface 11. In Islands, due to limited extent of fresh water aquifers, rain water harvesting is the most preferred source of water for domestic use 12. In desert, where rain fall is low, rain water harvesting has been providing relief to people

The concept of watershed development is based on the idea that rainwater can be harvested, the direct run-off of water reduced and the groundwater recharged. Watershed management has been a comprehensive approach aimed at optimizing the use of water, land and vegetation in any area. It is highly effective in channelizing water availability that helps to alleviate drought, moderate floods, prevent soil erosion, increase fuel, fodder and agricultural production on a sustained basis while keeping the inherent productivity of the soil resource intact.

The all-welded wedge wire screens are made from two elements the V-shaped wedge wire is helically wound around an array of internal longitudinal support rods. Each intersection of wire and rods is automatically resistance welded, creating a very strong cage-like cylinder with one continuous slot spiraling along its full length. The gap between the wires, also called slot or aperture, is manufactured to customer specification, allows water to flow from the surrounding aquifer into the screen, The slots can be very narrow to keep out fine sand grains, which could otherwise damage your pump through abrasion. NON PLUGGING SLOTS V-shaped wire creating, two point particle contact preventing plugging. Inwardly opening slots (in-flow) preventing sand particles from remaining lodged in screen. The V-shaped wire enhances well efficiency, ensures consistent pumping and long well life. LARGE OPEN AREA The continuous slot wedge wire offers higher open area than any other type of screens used for water well applications, such as slotted pipe, punched pipe, louver screens. Wedge wires for each application are selected to maximize open area, resulting in the lowest possible cost for water extraction. TECHNICAL DETAILS Available sizes from 1“ (25 mm) to 22“ (560 mm) Water well screens designed to suit well depth Available in slots sizes from 0.15 mm to 3 mm Length up to 6 metres available Materials: LCG (Low Carbon Galvanised) / SS304 / S316L / SS316 / SS316L - or as required to meet Customer requirements. End fittings - to suit Customer requirements

An observation well means a non-pumping, non-potable well used for measuring groundwater levels or potentiometric surface. Observation wells can be used to show that a well is obtaining water from an isolated aquifer, or perhaps that the aquifer is connected to other aquifers or surface water. Piezometers are excellent for capturing water flow, strata permeability, and depth of water pressure.
