Groundwater fails to replenish expanding concrete jungle

THANE/MUMBAI: A state department’s groundwater survey has found that the selection of spaces within the Konkan area seeing a drop in water ranges has higher nearly seven-fold since 2015. While 629 spaces or villages in Konkan witnessed a drop of as much as 1 mt this yr, the corresponding quantity was once 95 mt in 2015 when the state confronted a water crisis because of vulnerable rainfall the former yr.
Forty one spaces registered a drop in Thane district, whilst 163 spaces in Raigad and 176 in Palghar registered water depletion of as much as 1-metre ranges. For the primary time, the luxurious Konkan belt has noticed this fast depletion of water inventory, which even though beneath 1m, generally is a reason behind concern, mentioned professionals.

Geologist Amar Joshisaid the speed of success for borewells in Mumbai has been decreasing every year, with nearly part of the efforts failing to strike water.


The Maharashtra Groundwater Act permits digging as much as 200 toes but other people have dug as much as 800 toes in Mumbai and no longer were given water. “I latterly visited one website in western suburbs and located one borewell 600 toes deep and another 800 toes—and both had no water,” mentioned Joshi.


Officials characteristic the drop to deficient rainfall this yr and excessive draining of the inventory from the underground aquifers (natural reservoirs). Borewells are dug because of residential and farming wishes, but indiscriminate digging can lead to sooner depletion of the underground inventory. “Water percolation within the floor requires a gentle pattern of rainfall as simply heavy rains don’t necessarily mean good percolation. The rains, even of a light drizzle, must closing an extended duration for max percolation which wasn’t noticed this yr,” mentioned an legit from the ground water supply department from Pune. The losing ranges may well be a sign of excessive suction of water, he added. Rampant urbanisation and concretisation had worsened the location.


Joshi mentioned, “With massive portions of the city being concretised, where and how will the recharge of water take place? Mumbai being an island, the rising salt water will contaminate the entire soil, making it saline.” BMC officers say they dissuade other people from digging underneath 25-30 metres for borewells for the reason that water tunnels within the town run 50 metres deep. “As a precautionary measure digging for borewells that deep is not allowed ,” an legit mentioned.
