There are four centrifugal pumps, two each for each of the wet wells. The pumps were designed so that only two would be required to handle the max. flow rate of 2.62 MGD. This means that if one well needs repair all the flow can be diverted to the other wet well and the plant will not suffer any serious set backs. The pumps are driven by four DC motors. The motors are difficult to maintain and are set up in such a way that makes servicing them difficult. This becomes an even more difficult problem because there is only one person in the Guilderland area that is capable of servicing the motors. The pumps are capable of handling 3250 gpm under 46 ft TDH. The pumps lift the raw sewage and discharge it through a 16 in. force main to the head of the primary clarification tanks.
