Background
The Marin Headlands is a robust community of park visitors, non-profits, park partners, residences, concessionaires, and housing for 134 NPS staff members and interns. Over 4 million visitors per year visit the
Marin Headlands. Sewage from the Marin Headlands is pumped via forced main through the Baker Barry tunnel to Fort Baker. Pump station 840 is the final station in the Marin Headlands. From this station, all sewage produced in the Marin Headlands is pumped via forced main out of the Marin Headlands to Fort Baker, and from there to the Sausalito Sewer District. The station pumps around 60,000 gallons of sewage a day during dry weather and 150,000 gallons during rain events. The station is powered by three-phase power supplied by PG&E and is backed up by a NPS-owned stationary diesel generator. In August, 2025 it was discovered that the ATS was not functioning properly. Replacement of the existing genset and ATS with a new genset and ATS that match the performance standards of the existing is required.
Project Description
The contractor will be responsible for the removal and disposal of the existing Kohler generator (model
#135ROZJ, Serial #0729271, Spec PA-189724). The contractor will furnish and fully install new genset that matches the performance of the existing generator. The contractor will remove and dispose of the existing automatic transfer switch and replace with new that matches the performance standards of the existing.
