Peña Adobe Lift Station and Force Main
City of Vacaville, California

This project included an evaluation  of alternatives to serve the new Lower Lagoon Valley development. The project evaluated various options including gravity sewer and lift station alternatives. The selected project included a new 1.6 mgd lift station with a biofilter for odor control and approximately 2,500 feet of dual 8-inch diameter force mains.

Approximately 1,500 feet of the force mains will be installed by the horizontal directional drilling (HDD) “trenchless” construction method under Butcher Hill (about 150 feet high). HDD construction will allow the pipe to be constructed while minimizing impacts to existing cultural resources in and around Peña Adobe Park.
