Coleman Engineering Chosen to Implement the Sewerage Commission—Oroville Region’s Primary Influent Pump Station No.2

Construction Management Services to bring this Project to a Successful Conclusion

The Sewerage Commission – Oroville Region (SC-OR) operates a wastewater treatment plant serving the City of Oroville and surrounding communities. The plant’s design average dry weather flow capacity is 6.5 million gallons per day (mgd); though it can temporarily receive major peak wet weather influent flows up to 26 mgd due to extensive inflow and infiltration in its sewerage network. SC-OR turned to Coleman Engineering to provide full construction management, resident engineer services and engineering services during construction for the WWTP’s new $7 million Primary Influent Pump Station No. 2. New facilities include a new 17 mgd wet well structure, four submersible pumps and associated piping and valves; a bar screen structure; two large diversion boxes; a new electrical building to house electrical equipment; a new diesel engine generator; new flowmeter vaults; yard piping, new and modified electrical equipment; and site improvements. Construction is due for completion by mid-August 2022.
