Project Details

The Pasadena Pump Station is one of three major pump stations that receive water from the Val Vista Water Treatment Plant and distribute it within the City Water Service Zone (City Zone), with the Pasadena site providing approximately 60% of the flow to the City Zone.

The Pasadena Pump Station and 10 million gallon reservoir were originally constructed in 1952.  The original pump station was replaced in 1982, but the original reservoir remains in service today.  The pump station includes ten (10) existing pumps. Several of the pumps and motors are past their useful life and need to be replaced. The reservoir floor has a history of cracking in numerous locations. Installation of a reservoir liner will provide a factor of safety against future crack development and water loss from the reservoir.  In addition, major electrical equipment components are at the end of their service life, and must be replaced due to obsolete components or limited availability of replacement parts.

This project will increase station pumping capacity the reliability and level of service of the pump station to meet existing and projected water demands in the City Water Zone. Proposed improvements include a new electrical room, electrical and controls systems, pumps, motors and a new chlorination system.  In addition, this project will install a solar-powered reservoir mixing system to improve water quality, upgrade the existing electrical systems, and site security will be improved with the installation of a card access system, gates and masonry walls. This project will also install a reservoir liner over the existing concrete floor and walls.
