Partridge Lift Station was constructed in 2010 and serves the Thunderbird Mobile Home Park, and two (2) professional lots on Partridge Street.  This lift station required excessive maintenance due to the frequent pump clogging caused by flushable wipes from the tributary area. GGSD provided public education and outreach to the tributary area in the past few years but no noticeable mitigation was observed in the pump clogging issue. The lift station improvements consisted of the installation of a grinder to the station’s influent sewer and conversion of the existing SCE electrical service to three-phase power. Installation of the grinder relieved the pump clogging issue at the Partridge Lift Station and reduced frequent pump maintenances at the lift station. 

The contractor, Pacific Hydrotech Corporation, has completed this project in accordance with the plans, specifications and other contract documents.

The project was funded with Sewer Funds and was completed within budget and on schedule.  The retention payment will be released after recordation of the Notice of Completion with the County of Orange.

It is recommended that the Sanitary District Board:

• Accept Project No. CP1141000 – Partridge Lift Station Improvement Project as complete, and authorize the General Manager to execute the Notice of Completion of Public Improvement and Work; and

• Authorize the Finance Director to release the retention payment when appropriate to do so.
