Canal West Pump Station Upgrades - City of Antioch, CA
 |
 |
The City of Antioch is one of the oldest towns in California, founded in 1850. The City is mainly a "bedroom" community with most adults working in larger cities toward Oakland and San Francisco. Known for its beautiful landscape and large homes, the City has seen an enormous amount of growth in the last 30 years. There are dozens of new communities to choose from putting a stain on the City’s infrastructure.
Constructed in 1959, the Canal West Pump Station consisted of one 125 and one 200 horsepower (hp) pump delivering water to the Antioch Reservoir and the City’s water treatment plant. The City installed a third, 125 hp pump shortly thereafter. The pump station is the main source of raw water for the City.
The City of Antioch recently increased the capacity of their water treatment plant to approximately 40 million gallons per day (MGD) of untreated water. In order to meet the treatment plant’s full capacity, the City elected to replace the 200 hp pump with a 300 hp pump such that in combination with the other two 125 hp pumps, the station could meet the 40 MGD capacity.
Pakpour Consulting Group in conjunction with its electrical and mechanical subconsultant, YEI Engineers, provided design services for the replacement of the 200 hp pump with a more efficient 300 hp pump and electrical upgrades allowing concurrent operation of all three pumps.
Other design features included construction of a new building to house the electrical equipment, installation of a permanent 450 kW emergency generator, an automatic transfer switch and SCADA. The new emergency generator will allow the City to operate the new 300 hp pump along with one (1) 125 hp pump.
