Water Research for Local Recharging of Ground Water Table

Abstract

The proposed system, helps to increase ground water table level to decrease the water crisis encountered by the people. The rain water harvesting system implemented by the government was a good system by the way but very less monsoon and unpredictable rain has made it unreliable for water table recharging. But an average household of 4 uses nearly 220 litres for bathing and nearly 200 litres for cleaning clothes and utensils per day all the water goes down for the sewage. This project aims in segregating these 400 litres of used water. By collecting all the used water in house and finding out its turbidity using led and photo detector. If water is turbid contents it is discharged into the sewage if the water is not turbid then the water is filtered using corn cobs and then diverted into the rain water harvesting system. This way at least 30 % (120 litres) out of the 400 litres of the used water can be diverted into the rain water harvesting system. When calculated for a month nearly 3600 litres can be recharged into the ground. The water diversion can be done with the help of a valve controlled by a solenoid. These are connected to the microcontroller to control all the process and send to Wi-Fi module.
