LEE + RO has been awarded a contract from the Los Angeles County Department of Public Works (LACPW) for design improvements at a sewage lift station and force main in the City of San Dimas. The contract is for the preparation of preliminary design plans, final design plans, specifications and construction cost estimate, bid support services, and construction engineering support for the rehabilitation and improvements to the Tract No. 37003 Sewage Lift Station and force main.
Since the construction of the force main and lift station in the mid-1980s, several small projects have modified the facility and force main piping. The force main has experienced repeated failures and exhibits signs of corrosion, and the coating within the lift station wet well appears to have pinholes and blisters. Several lift station site features are in poor condition having exceeded their beneficial life.
The scope of work includes:
- Studying the various possible alignments for the replacement of the force main and recommendations for the optimal alignment.
- Creating a design for the replacement of existing asphalt paving at the pump station site.
- Creating a design for replacing minor mechanical piping and valve modifications at the pump station.
- Specifying the wet well coating repairs.
