Central/Eastshore Pump Station Improvement Project

Provide a new pump station and new 36-inch outfall pipe to handle the flow from a 10-year storm. Add a standby generator and automatic trash rack.

The existing pump capacity at this pump station is insufficient to handle the flow from a a 10-year storm.  The existing 21-inch outfall does not have the capacity to handle the flow from a 10-year storm at the current 10-year high tide or the anticipated future high tide.

This project will provide a sufficient pump station that can handle the flow of 10-year storm, which will protect the neighborhood from flooding. Trash and debris will be captured by a proposed automatic trash rack in the pump station. This will improve the water quality in the bay, which in turn protects the habitats of the bay.

Part 2 - Detail

This improvement project will be for the Central/Eastshore pump station.  It will include the demolition of the existing station and abandoned dry well.  A new station structure will be constructed and will include a wet well discharge and automatic trash rack structure.  To address the current deficiencies to the pump capacity and operations and maintenance issues, new pumps will be installed along with new pump barrels, piping, flap gates, backflow preventer and hose for wash down.

The insufficient outfall capacity will be corrected with the installation of a new 36-inch RCP outfall.  A new standby generator and ATS will address the lacking backup power to the pump station.  Installation of a automatic trash rack will pickup debris and trash that would otherwise be discharged at the outfalls.  New wiring, motor controls, and new transformer will be required for the new equipment.  A site fence will be needed to secure the pump station.

The City of Alameda has ten water pump stations.  The primary goal is to ensure that the City's pump stations have the capacity to handle storm water flows from a 10-year storm event during the current 10-year high tide, as well as during the anticipated future 10-year high tide.  The reliability and capacity of these stations is of utmost importance due to the low elevations in the majority of Alameda and potential for flooding from wet weather events during high tides. Currently, the Central/Eastshore storm water pump station has inefficiencies in the installed system.  A hydraulic analysis of the pump station determined that the actual pumping rate, when both pumps are running, is significantly less than the station's design capacity. In addition, the existing 21-inch outfall and pump discharge structure were analyzed to verify capacity to handle the incoming flow from a 10-year storm event during the current 10-year high tide and future high tide.  It was found that at the current 10-year high tide elevation, the existing pump discharge structure would be insufficient to handle the flows from the design 10-year storm.  The anticipated future high tide elevation further limits the hydraulic capacity.  This pump station improvement project will resolve all these issues.  

If the proposal is not implemented, the deficiencies of the existing pump station and the pump discharge structure will likely lead to flooding resulting from a 10-year storm event during the current 10-year high tide.  The lack of an automatic trash rack will allow for trash/debris to discharge at the stormwater outfall.  This will impact the water quality of the bay, thus impacting the habitants of the bay. 





i. Water Supply (conservation, recycled water, groundwater recharge, surface storage, etc.)


ii. Water Quality

Minimizing health impacts in the waterways by reducing the amount of pollutants discharged into the bay.

iii. Flood and Stormwater Management

This project will improve stormwater discharges to the bay.

iv. Resource Stewardship (watershed management, habitat protection and restoration, recreation, open space, etc.)


Habitat protection by minimizing the discharge of trash/debris into the waterway through stormwater discharges.
