GROUND WATER RECHARGING

In urban areas is done by collecting the rainwater from the rooftops and the portico of the house and by making it easily absorbed within the veranda space.


The method: An absorption pit should be constructed in the sloped area of the house veranda. The size of the absorption pit should be a minimum of 5 feet in width and a maximum Depth depend upon water consumption by bore and veranda space. RCC precast module should be installed to make the necessary size of absorption pit. At the bottom of the pit, a casing pipe with two SS filter screen should be fixed tightly to the bore well pipe. This middle part of two SS casing pipe should be filled with filter sand and it will function as a filter. The floating matter will be float on water, the heavy matter and silt will be settled at bottom not clogging the filter media and can be easily cleaned and pit can also hold the excess water quantity for recharge. The pipe, which is installed for collecting the rainwater from the rooftop and the veranda of the house, should be linked to this absorption pit. Another pipe should be deployed for allowing the excess water to run off into the storm water drainage. Thus, by effectively preventing the rainwater from running off into the drainage and by making it absorbed into the ground, ground water sources can be recharged.

BOREWELL RECHARGE

Recharging of borewells should be done to prevent them from drying up and improve their water table


It is usually done by the following method. First, a pit should be dug in the region surrounding the casing pipe and RCC precast modules should be installed in it. The size of the pit should be 5 feet in diameter and 7 to10 feet in depth. At the bottom of the pit, a casing pipe with two SS filter screen should be fixed tightly to the bore well pipe. This middle part of two SS casing pipe should be filled with filter sand and it will function as a filter. The floating matter will be float on water, The heavy matter and silt will be settled at bottom not clogging the filter media and can be easily cleaned and pit can also hold the excess water quantity for recharge. A pipe should be fixed to collect the rainwater from the roof and this pipe should be connected to the pit. A pipe should be fixed to prevent the excess water from running away to roadside drainage. By following the above method, we can recharge our borewells and keep them alive always. Those having open wells too can adopt this system. By directing the filtered rainwater to the open wells, their water tables could be improved.
