Document Description
The project proposes to upgrade the existing Influent Pump Station (IPS) at the Soscol Water Recycling Facility (SWRF) to pump incoming flows up to 60 mgd. The proposed project would be designed to pump flows up to 20 mgd to the SWRF headworks and flows in excess of 20 mgd to Oxidation Pond No. 1. The new IPS would be located to the west of the existing IPS. The new IPS includes approximately 150 linear feet of new 66-inch influent sewer pipeline to the new IPS, new sewage forcemain piping to manhole No. 9 from the new IPS, an emergency diversion pipe to the water recovery basin and site paving and grading. The project would also include improvements to the IPS screenings area and manhole No. 9. The existing vactor dump site would be demolished and rebuilt, and a new electrical building, odor control facility, and flowmeter vault would be constructed.
