Area 9 acres i.e. 9 x 4047=36423 sq.m. Avg rainfall at Haridwar is 2100 mm / year. So the quantity harvested  by you will be 36423 x 2.1= 76488 cu.m. i.e. 7 cr. 65 lakhs litres. A film lined farm pond type structure will cost nearly Rs. 0.15 (15 paise) per litre. It will be better to construct 4 ponds of 2 cr. ltrs each. The ponds will take approx. 10 acres area, depending on the depth you can dig to.

For the fish, you have to feed them, the feed added to the ponds make the water unfit for filters in drip system. I think one or two of the ponds can be used as fish pond as per your need. 

We can further discuss the matter on mail. I'll give you a test mail from my  mail id.
