Allegiance Digital Electromagnetic Water Flow Meter, 50 mm (2 Inch) simply known as Electro Mag flow meter is a volumetric flow meter that is ideally used for wastewater applications and other applications that experience low pressure drop and with appropriate liquid conductivity required. The device doesn’t have any moving parts and cannot work with hydrocarbons and distilled water. Mag flow meters are also easy to maintain. Magnetic flow meters work based on Faraday’s Law of Electromagnetic Induction.

"Rainy" Rainwater Harvesting Filters Completely Indigenous and Patented Technology for Dual Intensity Rainwater Harvesting Filters called 'Rainy'. For groundwater recharging, our innovation uses an injection well equipped with "V-Wire Screens" that enables replenishment of groundwater source. Rainwater is one of the purest source of water with less then 50mg/ litre of Total Dissolved Solids (TDS). Minimalistic, easy-to-install and easy to maintain Products. Reduction of Carbon Footprint and Recharge water source to avail clean water for consumption. Working Principle: When the rainwater along with dirt & debris flows by gravity through the downtake pipes, it enters into the filter and starts rotating in anticlockwise direction at the periphery of the upper housing, this enables it to flow into the SS-304 filter element placed in the lower housing in angular motion at specific speed & velocity, which creates cohesive force at low intensity & centrifugal force at high intensity of rainfall. In both situations, involving low & high intensity of rainfall, the working principle of the filter based on cohesive & centrifugal force respectively, aids the filter element to flush out dirt & debris automatically. The water then passes through the drain outlet and simultaneously diverts clean water into the sump/ recharging well through the clean water outlet, which can be used for reutilization or recharging of groundwater source. Special Features : What makes 'Rainy' unique? Dual Intensity Filters works on the principle of Cohesive & Centrifugal force. The open drain design does not allow stagnation of water and dirt particles. Works on Gravitation force (No external energy required). Cost effective and affordable. Compact in size and wall mounted. Inbuilt self-cleaning mechanism. Automatic flush out of dirt and debris. No consumables required. Flexibility in pipe connection to any angle. Tough UV stabilized high density polyethylene housing. Filter Element SS-304 Multi-Surface Screen food grade. All the material used are food grade and recyclable. Filter Pipe connections can be turned up to 360 Degrees allowing it to suit the given site conditions. Simple in connection, which any local plumber can easily install. The filter efficiency remains unchanged even with the variation of intensity of rainfall. The filters do not have any moving parts; there is no wear & tear of the filter allowing for long life span. Technology works on the Gravitational Principle so saves power (reduces the pumping of water from distant places & depths). Swirling movement of water is formed while ‘Rainy’ filters are under operation, this leads to aeration of water. Thus, increases the water quality.

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

Borewell Drilling Services for Industries, Factories, Schools, Colleges, Universities, Buildings, Flats, Hotels, etc. The direct rotary drilling method was developed to increase drilling speeds and reach greater depths in most formations. The borehole is drilled by rotating a bit, and cuttings are removed by continuous circulation of the drilling fluid as a bit penetrates the formation.

An observation well means a non-pumping, non-potable well used for measuring groundwater levels or potentiometric surface. Observation wells can be used to show that a well is obtaining water from an isolated aquifer, or perhaps that the aquifer is connected to other aquifers or surface water. Piezometers are excellent for capturing water flow, strata permeability, and depth of water pressure.

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.
