Senior Engineer West Yost Associates Vacaville, CA
This project involves rehabilitating an aging collection system using a variety of innovative methods including trenchless pipe bursting for replacing an existing force main, cured in place pipe for re-lining leaking gravity sewers, and constructing a new triplex pump station with a 10’ dia. wet well below the water table.
Challenges and related solutions to replacing and upgrading several small lift stations will be discussed along with methods used to retrofit existing lift stations with better access, install new pumps, and replace control panels with SCADA capabilities while retaining existing wet wells. Methods used to prioritize collection system rehab will be discussed in the context of funding repairs with limited capital from SWRCB and USDA grant programs.
Understand the benefits of trenchless construction methods.
Gain insight about constructing a wetwell using rolled steel casings in a drilled hole in lieu of extensive dewatering.
Minimize construction costs and impacts related to underground construction while leveraging engineering analysis to prioritize where to spend limited capital.
