Discussion:
The city's primary sanitary sewer lift station (L-16) exists with a sewage grinder installed in 2014. The sewage grinder is still in operation but is failing to a point where it must be immediately replaced, as to keep the pumps and valves free of clogs, as the lift station is currently operating with two of the three pumps.
A new pump was approved by Council to be purchased in December of 2019. The sewage grinder is a different piece of equipment than a pump. This piece of equipment is in a manhole and grinds any debris in the sewage before it enters the wet well to be pumped out to the force main.
An evaluation and feasibility study are currently underway for the upcoming L-16 Rehabilitation Project (SEWER-19-001, see attached CIP summary sheet). But as indicated, the failed sewage grinder must be replaced immediately. The feasibility study has been advanced far enough to determine an appropriate sewage grinder replacement will be compatible with the upcoming and ultimate L-16 rehabilitation project.
With that said, quotations were solicited and received as follows:
Sewage Grinder Replacement
Electric Pump $37,713.58 (JWC Channel Monster)
Franklin Miller $39,934.00 (Taskmaster Grinder)
Accordingly, the low bid for the pump is from Electric Pump in the amount of $37,713.58. This estimate includes installation and setup costs.
