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

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.

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%.

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
