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

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.

Allegiance Water Level Indicator Flat tape water level Indicator Enhanced Laser Marked Tape Features Durable PVDF non-stretch tape Improved electrical properties Thicker dog bone design prevents clinging to sides of the well Permanently laser marked every 1/100 ft or each mm The PVDF flat tape is laser marked every 1/100 ft or each mm; lengths up to 5000 ft (1500 m). New flat tape has increased tensile strength and electrical efficiency by using 6 strands of copper coated stainless steel and 13 strands of stainless steel in each conductor. The P7 Water Level Meter Probe is engineered to allow submersion to 1000 ft. (300 m). Sensor at the tip of the probe provides

CGWA Clearance Central Ground Water Board (CGWB) . Statement indicating position of pending cases received for NOC for ground water withdrawal. Statement showing list of project proposals to whom NOC for ground water withdrawal has been issued. The annual replenishable ground water resources availability plays an important role in defining the guidelines. The latest assessment of the state wise ground water resources as on 31.03.2009 is available at the Central Ground Water Board . As per the ground water resource estimates of 2009, out of the 5842 assessment units (Blocks, Mandals, Talukas, districts), 802 over-exploited units, 169 critical units, 523 semi-critical units, 4277 safe units and 71 saline units have been identified across the country by Central Ground Water Board. The Annual replenishable ground water resources have been estimated as 431 Billion Cubic Meters (bcm). The Net Ground Water Availability is 396 bcm and the overall stage of ground water development of the country is 61%. Therefore, prior permission/NOC from CGWA has to be obtained before construction of any Groundwater abstraction structure viz. Tube wells, Bore wells, Dug wells etc. Allegiance can offers its client the following services: Examining the area of the groundwater against availability Water requirement Availability of aquifer A Shallow aquifer B Deeper aquifer Status of the groundwater development of the area Preparation of proposal for augmentation of groundwater abstraction Preparation and implementation of water conservation measures Facilitation for obtaining NOC from CGWA, New Delhi
