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

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.

Digital water flow meter as per CGWA Compliance ELECTROMAGNETIC FLOW METER Digital Flow Meter With Telemetry As Per CGWA Guidelines Installation of Digital Water Flow Meter on Ground water abstraction structures Whereas the Central Government constituted the Central Ground Water Authority (hereinafter referred to as the Authority) vide notification Number S.O. 38(E), dated 14th January, 1997, followed by notification number S.O. 1124(E) dated 6th November, 2000 and S.O. 1121 (E) dated 13th May, 2010 of the Government of India in the Ministry of Environment & Forests, for the purposes of regulation and control of ground water development and management in the whole of India and to issue necessary regulatory directions. And whereas the Authority has issued ‘Guidelines to control and regulate ground water extraction in India’ vide notification number 3289(E) dated 24th September, 2020, wherein under Section 9 (i) “Installation of digital water flow meter (conforming to BIS/ IS standards) having telemetry system in the abstraction structure(s) shall be mandatory for all users seeking No Objection Certificate and intimation regarding their installation shall be communicated to the CGWA within 30 days of grant of No Objection Certificate through the web-portal.” THIS IS TO BRING TO THE NOTICE OF ALL GROUND WATER USERS THAT: All the project proponents/users drawing ground water and seeking/having NOC shall have to mandatorily install tamper-proof digital water flow meters with telemetry on all the ground water abstraction structures within their premises. All the Micro and Small Enterprises drawing less than 10 cum/day shall also be mandatorily required to install digital water flow meters on all the ground water abstraction structures within their premises. Such enterprises shall be subjected to randomised inspections. The afore-mentioned conditions need to be strictly followed by all the users and any ground water withdrawal without the installation of tamper-proof digital water flow meters and telemetry (wherever applicable) shall be construed as illegal. 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.
