A SSMP or a Sewer System Management Plan is a document that describes the activities a wastewater or collection agency uses to manage wastewater collection systems effectively. Causey Consulting, Walnut Creek, CA assisted TSD with the preparation of this SSMP.
Truckee Sanitary District operates a sanitary sewer system that serves a full-time population of approximately 17,000 and encompasses approximately 39 square miles in Placer and Nevada County. The sewer system serves approximately 13,400 residential and 2,000 commercial service connections as of January 2020. The sewer system consists of 215 miles of gravity sewer pipeline segments, 3927 manholes, 15.5 miles of force mains, forty-four (44) lift stations, and 17 sewer flow metering sites. The lift stations include twenty (20) large lift stations and twenty-four (24) small lift stations. The sewer pipelines range in size from four (4) inches to twenty-four (24) inches in diameter. The District is responsible for seventy-four (74) miles of lower laterals, and private property owners have the responsibility for the upper lateral (i.e., portion of the lateral located on the property owner’s parcel). Finally, the District system also includes three (3) sewer siphons.
The District also receives sewage from one satellite system operated and maintained by the Northstar Community Services District (NCSD). All wastewater is conveyed to the Tahoe-Truckee Sanitation District (T-TSA) for ultimate treatment and disposal.
