Recently, I did ground water exploration survey for my land located close to a dam (600 meter away) but at an elevation of 200 meter from the water body. The repot says the water yield expected is 400 LPH 3/4" 1" by 90deg Vnotch. The report also mentions that the water source is expected at 180-210 ft and 270-315 ft. I need to know whether I should dig a borewell upto 210 ft or 315 ft ? Also, I want to understand whether water yield 400 LPH 3/4" 1" is an average/ low/ high yield?
