Unfortunately the cracks are highly contaminated with effluent. That makes bonding of any type of injection material questionable. This will be difficult to correct without taking the tank out of service and providing a proper repair from the inside of the tank.

Could he
(1) empty the tank (to eliminate continued water pressure on the wall)
(2) sandblast the outside of the tank
(3) apply a sealant to the outside to the cleaned concrete (to stop flow after it has gotten through the old wall), then wrap the tank with fiberglass to reinforce the old walls
(4) then wrap the outside wall with tension cables to prevent the walls from structurally failing?
That is, use the exterior sealant and fiberglass to prevent seepage through, and use the outside fiberglass and cables to prevent wall failure against the static pressure?

Does the tank have secondary containment? It would buy you some time to implement the repairs. Does your state require you to report the leakage? If so, don't delay reporting the problem.

If it is a leak form the inside, i would think the only thing you can do, for longevity, is to repair from the inside? I have never dealt with WWT but clean water tanks that have small hairline leaks we have repaired from the inside with quick plug. May be worth talking to a manuf. but Ron brought up very important details
