I appreciate all of the input. Unfortunately, the flow and the head are set, we cannot adjust them. The pump control valves we are considering are slow open/close valves, just downstream of the pump. The pumps actually start against a closed valve that opens/closes slowly to prevent surge.

Thanks for the input. We have been considering adding VFDs and soft starts, however due to the existing site constraints and existing MCC, VFDs are much more expensive.
Soft starts may be an option (about the same cost as a surge control tank) however, I'm concerned a soft start will only ramp...
I am considering installation of either a surge tank or pump control valves to solve a surge problem associated with starting/stopping of 60Hp, 550 gpm pumps. This lift station is pumping treated wastewater effluent. The cost for both options is about the same.
Here's my question:
