Document Description
Eastern Municipal Water District (District) owns and operates the Winchester Lift Station (LS), located at Olive Avenue and La Ventana Road in the City of Winchester, Riverside County, California. The LS receives flows from the collection system and discharges to the Perris Valley Regional Water Reclamation Facility (RWRF) for treatment through a series of force main and gravity sewers. While the foul air is not currently treated, nitrate dosing at the LS provides a reduction in odor concentration without fully eliminating the offending odors. The Winchester Lift Station Odor Control Project (Project) proposes to construct and operate a bio trickling filter (BTF) with dry media polishing, vapor-phase treatment application, within the footprint of the existing facility. The proposed project will be located on the upper northwest corner of the site; new buried piping will convey the foul air from the lift station wet well to the new odor control facility as shown on drawing C1. A new concrete gutter will also be constructed around the odor control facility slab and will connect to the exiting gutter routed around the perimeter of the site. The project also proposes to rebuild the masonry wall in the southwest corner of the site and extend the masonry wall to encompass an additional lot that the District has secured to the east, along with a new access gate along Olive Avenue, also shown on drawing C1.
