Suggestions
January - June 387.5 310 Fits into the aquifer
Schedule staggered withdrawal during these months and
consume lessJuly - December 801 640.8 Around 41
mm will flow out
Withdraw continuously during the three
months and consume comfortable
SOLUTIONS
UTILIZATION OF SHALLOW AQUIFERDO AND LEARN PHASE• 1 designated lane • Recharge wells and one
withdrawal well• Budget ~ Rs. 3-6 Lakh• Observe: Impact on
seepage, response of APR residents, water quality and quantity
• Also roof top rainwater harvesting by towers and/or villa
END GAME • Replicating lane by lane
do and learn phase model
