County of Alameda Public Works Agency

The Eden Landing pump station utilized 35-year old natural gas engines to operate the storm water discharge pumps.  These engines, at the end of their useful life, were in need of replacement.  MGE’s scope of work for this project included:


  • Data Gathering:  Field investigation and measurements, review of existing As-Built and repair drawings, and evaluation of operational conditions.
  • Inspect underground discharge lines for condition; prepare rehabilitation drawings and specifications if necessary.
  • Design replacement of (4) Natural Gas Engines with VFD pumps and SCADA control.
  • Prepare replacement and rehabilitation drawings, specifications and estimate for site improvements, new control building, engine replacement, existing pump rehabilitation, installation of emergency generator, street frontage improvements and upgrade of station electrical power.
  • Investigate existing station discharge pipeline, and prepare conceptual rehabilitation drawings for discharge line repair.


This project presented significant challenges in the phasing and staging of the station rehabilitation in order to convert this facility from a natural gas operated pump station to an all electric facility without loss of capacity and function during the 1 ½ year construction duration.  Construction completed in 2013.
