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 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

AWM MAG-110 - Smart Series EM Flowmeter Allegiance Electromagnetic Flow Meter, simply known as mag flow meter is a volumetric flow meter that is ideally used for water, mild acid or alkali, salt solution, pulp, wastewater (ETP, STP, WTP & WWTP) and other conductive media that experience low pressure drop. However, the medium must not contain enormous ferromagnetic materials and bubbles. It is widely used in the flow measurement of metallurgy, papermaking, environmental protection, petroleum, light textile, chemical industry, pharmaceutical industry, water conservation, municipal construction, food industry and other fields. A mag meter operates on Faraday’s Law of Electromagnetic Induction which states that a voltage is induced when a conductor moves through a magnetic field. The liquid flowing through the pipe acts as the conductor and this induces a voltage which is proportional to the average flow velocity. This voltage is detected by sensing electrodes mounted in the Magflow meter body and sent to a transmitter which calculates the volumetric flow rate based on the pipe dimensions. Allegiance Digital Flow Meter With Telemetry is manufactured as per CGWA Compliance and provides effortlessly smooth performance. Unlike traditional flowmeters, the main meter sensor is designed to have no moving parts that eliminates frequent maintenance.

Types of Soil tests for building construction works depend on properties of soil. Design of the foundation is based on soil test report of construction site. Soil tests for construction of buildings or any structure is the first step in construction planning to understand the suitability of soil for proposed construction work. Soil which is responsible for allowing the stresses coming from the structure should be well tested to give excellent performance. If soil shouldn’t tested correctly then the whole building or structure is damaged or collapsed or leaned like leaning tower of Pisa. So, soil inspection or testing is the first step to proceed any construction Allegiance Water Management www.allegianceindia.in Email : info.allegianceentp@gmail.com Contact : 8690924755 ; 9408425896

Percolation Pit is also like Rainwater Harvesting System A percolation pit, in its most low-tech form, is a simple hole dug into the ground. It facilitates groundwater recharge through infiltration of surface runoff into the soil or rock. Differences to contour trenches: Better water storage capability due to greater depth. Percolation tank is an artificially created surface water body, submerging in its reservoir a highly permeable land so that surface runoff is made to percolate and recharge the ground water storage. The percolation tanks are mostly earthen dams with masonry structure only for spillway. Percolation tank is an artificially created surface water body, submerging in its reservoir a highly permeable land so that surface runoff is made to percolate and recharge the ground water storage. Percolation tank should be constructed preferable on second to third order streams, located on highly fractured and weathered rocks which have lateral continuity down stream. The recharged area down stream should have sufficient number of wells and cultivable land to benefit from the augmented ground water. The size of percolation tank should be governed by percolation capacity of strata in the tank bed. Normally percolation tanks are designed for storage capacity of 0.1 to 0.5 MCM. It is necessary to design the tank to provide a ponded water column generally between 3 & 4.5 m. The percolation tanks are mostly earthen dams with masonry structure only for spillway. The purpose of the percolation tank is to recharge the ground water storage and hence seepage below the seat of the bed is permissible. for dams upto 4.5 m. height, cut off trenches are not necessary and keying and benching between the dam seat and the natural ground is sufficient.
