A domestic well is located 30 m upstream from a neighbor\'s septic system. If domestic use of water is 1000 liter/day, what is the minimum regional flow (bqa) that will just suffice to keep septic effluent from entering the well (easiest to do analytically)?

Solution

Since the domestic well is upstream of 30m, from septic tank, hence minimum regional flow will be greater than the flow in the domestic well.
