Borwel problem in the gulbarga

Hi All,
Borwel problem
Area : gulbarga Karnataka (north Karnataka)
Tolal borwel drilling : 275ft
Total pvc pipe casing : 240ft( 140mm)
Bore size: 6.25inch

After checking 45days, now water depth is at 175ft,. But total depth become185ft,now sand came upto 55ft of raise,But will drilling we got water gaps at 200ft and sand bed at 230ft, after installing the 1.5hp of submersible pump at a depth of 175ft no sufficient water to come out,but surrounding bores are working fine at 200ft.

Shall I wait for another few days for raising water level?
Shall I plush the borwel again?
If I plush the borwel in future any problems?

Awaiting your response.
