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
