Rainy FL V Wire Technology

Our V Wire Technology helps in hassle free function of your Injection Well Recharge System

Vertical V Wire Screen

FL-V-WIRE INJECTION WELL TECHNOLOGY for runoff rainwater harvesting and recharge.

Objectives:

To develop a Point Source Artificial Groundwater Recharge structure which can recuperate dried bore wells within a very short timeframe employing an enhanced rate of recharge capturing the surface runoffs.

The FL V-Wire injection well technology invented by Farmland Rainwater Harvesting Systems in the year 2002 was significantly upgraded in the year 2007 due to constant research & development, both at the state of the art Hydraulic Research & Development Lab and at the field level. This technology is unique in many ways. It uses Gravitational Energy and the use of eco-friendly materials having a long-life span. The technology has gained wide spread acceptance by various Government Organizations in the State of Karnataka in Districts and Taluks which are highly drought prone, because of the positive results obtained in enhancing the water table in severely depleted areas. Hence, this technology has found wide acceptance in various Central and State Government sponsored sustainable schemes in providing water security for drinking and agriculture to the rural community in the drought-prone areas in many states of India. Because of the success obtained at the government level, the technology also gained ground in the private sector.

The system consists of a silt trap unit, a recharge well (5 to 6 meters with 20% filtration media consisting of crushed stone, gravels, coarse sand, activated carbon and charcoal; and the rest for storage of water) and a recharging bore (20 to 60 meters) at the bottom of the recharge well. The rain water is led through a water channel and first reaches the silt trap, which allows for silt to settle down in the chamber. The overflow water is led into the Injection Well fitted with the FL V-Wire filter unit through a horizontally connected pipe. It then passes through multilayer of filtration media placed at the top of the Injection Well.

The water accumulates below the filter media in a specially designed storage well, which creates a water column. The percolator pipe, attached to the non-clogging FL V-wire screen, is placed by boring through the permeable strata at higher depths of about 30 to 60 meters below the ground level. The water then passes through the permeable strata by gravity and reaches the dry joints, cracks, weathered zone; and recharges the aquifer holding the groundwater. The water also gets filtered while passing through the permeable strata.

Horizontal V Wire Screen

• Unique Slot Structure: Owing to the unique design of the screen, which enables slots to be present horizontally and vertically there is continual flow without any interruption. Further, this ensures that there is sufficient open space for water to enter into this medium without much head loss due to friction. This system allows for the overall efficiency of the tube well to be improved.

• Higher Filtration: Due to the slot-based approach of the v-wire technology, we are able to choose the size of the slots depending on the media around / in which it is going to be placed. This allows for high filtration of even the tiniest sand particles allowing for good control over particle infiltration thereby decreasing maintenance and increasing the life of the product.

• Anti Clogging: The salient shape and structural design of the V-Wire screen ensures that no sand or other particles get clogged in the system. This unique V shape results in the screen having a long endurance with no maintenance.

• Corrosion Free: High-grade material with anti-corrosive property is used to manufacture our screens and therefore assuring corrosion-free usage. This enables the longevity of the product.
