McKinley Village Storm Drain Pump Station / Sanitary Sewer Lift Station

The New Home Company & City of Sacramento Department of Utilities


Wood Rodgers provided Design and Construction Management services for the City of Sacramento’s McKinley Village Storm Drain Pump Station / Sanitary Sewer Lift Station, a shared storm and sewer pump station facility for The New Home Company’s McKinley Village development. The new facility designed by Wood Rodgers pumps storm water and sewer waste water from 336 single and multiple unit residential lots via two separate pumping systems sharing a common site. The 13.3 cfs capacity storm drain pump station design consists of a formed concrete intake structure designed per Hydraulic Institute standards, which contains a bar screen and automatic trashrack cleaner (Flexrake, Duperon Corporation), three constant speed vertical turbine pumps, and a low flow submersible sump pump. Water is pumped from detention ponds adjacent to the intake structure, to the City’s existing Sump 99 pump station approximately 0.8 miles away via an 18” pipeline. The 310 gpm capacity sewer lift station design consists of a circular wetwell with two submersible rail mounted pumps which discharge through a valve and meter vault, and a half-mile-long 6” forcemain to the City’s existing combined storm/sewer system. The project’s sewer facilities also includes an on-site below grade sewage overflow reservoir. To prevent surcharge flows during peak events in existing areas surrounding the development, additional instrumentation and controls have been provided to allow McKinley storm water or sewage to be temporarily retained within the storm water detention pond or sewage overflow reservoir, respectively.
