"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

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.

Injection well Technology is the most effective in capturing surface run off both from plain open loose area or from storm line and filtering in two stages by filtering rainwater through 4 stages of filtration through Silt Trap and Injection well. The silt traps takes care of most impurities in the first stage itself, as it has 40 mm gravels, 10 mm pebbles, charcoal, activated carbon and coarse send and horizontally fixed V wire non clogging SS screen of 500 mm length and 150 mm dia. Rainwater then flows through main Injection well where it flows by gravity through 40 mm gravels, 10 mm pebbles, charcoal, activated carbon and coarse send and vertically placed V wire non clogging SS screen of 500 mm length and 200 mm dia. on the recharge bore well. Air vent from bore well and main well is kept at center. The main well is designed to do maintenance whenever is required. As such the filtration media only needs cleaning once in a year Silt Trap and Injection well. The best technology to have head pressure by the way of water column to ensure fast recharge of ground water and recover the water levels in Aquifer.

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.

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.
