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. The State Water Resource Control Board (SWRCB) has issued Statewide Waste Discharge Requirements for sanitary sewer systems, which include requirements for development of a Sewer System Management Plan (SSMP). This SSMP has been prepared by TSD with the assistance of Causey Consulting, Walnut Creek, CA.

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 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.
