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

Injection well Technology is the most effective in capturing surface run off both from plain open loose area or from storm line and filtering in two stages by filtering rainwater through 4 stages of filtration through Silt Trap and Injection well. The silt traps takes care of most impurities in the first stage itself, as it has 40 mm gravels, 10 mm pebbles, charcoal, activated carbon and coarse send and horizontally fixed V wire non clogging SS screen of 500 mm length and 150 mm dia. Rainwater then flows through main Injection well where it flows by gravity through 40 mm gravels, 10 mm pebbles, charcoal, activated carbon and coarse send and vertically placed V wire non clogging SS screen of 500 mm length and 200 mm dia. on the recharge bore well. Air vent from bore well and main well is kept at center. The main well is designed to do maintenance whenever is required. As such the filtration media only needs cleaning once in a year Silt Trap and Injection well. The best technology to have head pressure by the way of water column to ensure fast recharge of ground water and recover the water levels in Aquifer.

Non-compliance of these conditions shall invite a Penalty provision and/or Environmental Compensation against the proponent for illegal withdrawal of ground water as per the CGWA Guidelines and may result in cancellation/rejection of NOC and sealing of ground water abstraction structures.

‘V’ Wire Injection Well Technology to Recharge Groundwater Source: • The Rain Water is lead through water channel and first reaches the silt trap, which allows for silt to accumulate in the chamber. The overflow water is lead into the injection well, passing through multilayer’s of Filtration media placed at the top of the injection well. The water is accommodated in a specially designed storage well, which creates water column, injecting large quantities of water into the deeper layers of the semi impervious earth’s strata through the Non Clogging V-Wire screens attached to the specifically designed percolator pipe, placed to a depth of 30 meters below the ground. The water column and the dual V-Wire Screen allow for the water to reach the dry joints, cracks, aquifers and recharge the ground water source. • This technology does not employ moving parts; the assured life span of the material is a minimum of twenty years. The maintenance cost involves desalting of the silt trap and replacement of filtration media once in five years. • The technology was adaptable to harvest rain water, irrespective of the presence of any bore well in place and also irrespective of terrain. The technology gave maximum flexibility to be used either in low lying areas or in upland conditions. • All materials used in this Technology are eco-friendly and recyclable. • Technology works on the Gravitational Principal Geomorphic profiling through vertical electrical Sounding of the soil strata is done to ascertain enormous quantity of water, quickly penetrating the rainwater into groundwater source. • The Provisioning of silt Trap fitted with Horizontal V wire Screen Filter eliminated the need of periodic maintenance and also facilitating significant volumes of rainwater to get into the recharging well.
