Increase ph of water by using Sodium bicarbonate

How can increase ph of water by using Sodium bicarbonate at which proportion

Your question should be more clear. Which PH do you want to reach to ?

What is the water current PH ?

I think you can do some basic tests and solve the problem.

A molar solution of NaHCO3 gives a pH of around 8. .saturated solution could give up to 9.You want higher pH use sodium carbonate solution as that can provide you pH of 10 to 11.
