Rainwater Harvesting through Point Recharge Method for Efficient Recharge of Tube Wells for Sustainable Management of Groundwater Resources in Karnataka

Water is a precious natural resource for sustaining life, agriculture and environment. The dependability on groundwater has reached high in all time recent decades due to reasons such as unreliable supplies from surface water vagaries of monsoon, increase demand domestic, agricultural other purposes. Karnataka largely dependent meet industrial, municipal, domestic irrigation needs. So, Rainwater harvesting (RWH) forms an important component development management resources agricultural, municipal industrial uses. Management scanty rain fall by harvesting, Augmentation depleting (deeper ground table) poor-quality scope conjunctive/domestic use need the hour. With withdrawal water, (GW) table declining at rapid pace with urgent recharge GW addition dilute poor quality water. Double ring technique Groundwater Recharge consists filtering different layers using gradation materials generally pebbles size synthetic material wrapped around casing pipe. By recharging into point soaking infiltration gallery established Irrigation Research Centre, (IWMRC) Belavatagi Tq: Navalagund shown encouraging results far quality, discharge are concerned. assessment influence through rainwater yield (lps), (dS/m) fluctuations (feet bgl) during year 2020, have that 3.35 lakhs liters could be collected 2020. Also, 7 events (rain July October 2020), it was observed considerable rise more than 100 feet below level 22 level, drastic reduction salinity i.e. electrical conductivity (EC) 10 dS/m average 1.32 tube well significantly increased 0.4 lps 2.4 lps. Therefore, Artificial techniques can better strategic approach combat emerging problems scarcity especially over exploitation its deterioration.
