About Us


South Placer Municipal Utility District (SPMUD) was founded by local community leaders from the City of Rocklin and town of Loomis through a grassroots effort in the 1950’s to create a customer-owned, regional sanitary sewer system for their communities. On September 24, 1956, the Rocklin-Loomis Municipal Utility District (R-L MUD) was established under the Municipal Utility District Act of the State of California ("MUD Act", Public Utilities Code of the State of California,§ 11501 et.seq., ). At its inception, the District covered an area of approximately 4,200 acres and had 452 connections. The District bonded for and constructed the original sewer infrastructure between 1958 and 1962, installing over 41 miles of sewer mains.

Initially, the District provided sewer collection and treatment via its own sewer treatment lagoon systems at various sites within the service area. These lagoons were decommissioned in 1974, when, under the Federal Clean Water Act, the District constructed a sewer pipeline to convey the sewage to the City of Roseville Dry Creek Wastewater Treatment Plant located in the southern end of Roseville. In October 2000, SPMUD partnered with the City of Roseville and Placer County to finance the construction of a second regional treatment plant called the Pleasant Grove Wastewater Treatment Plant located west of the City of Roseville, and was completed in 2005.

Over the years, the District has grown from 7 to 31 square miles as the City of Rocklin and Town of Loomis expanded their boundaries, and by annexing several unincorporated areas (Penryn and Newcastle to the north and Rogersdale in the Granite Bay area). In 1988, the District changed its name to South Placer Municipal Utility District (SPMUD) to reflect its larger service area. As of 2015, SPMUD provides sewer collection services over 21,000 connections, serving an equivalent population of approximately 75,000. SPMUD’s customer base has tripled over the last twenty-five years from 10,000 EDU to over 31,000 EDU.

General Manager

South Placer Municipal Utility District is a community based, customer-owned utility, governed by a five-member Board of Directors, elected by the registered voters within the district boundaries. The MUD Act requires the Board to hire a General Manager, who acts as the Chief Executive Officer and provides the day-to-day management of the operations of the District.

The current General Manager, Herb Niederberger, is a Rocklin resident and SPMUD customer since 1988. Herb has extensive experience in the planning, design, construction, operations, maintenance and management of municipal utilities throughout California. He is a registered Professional Engineer and Licensed Land Surveyor as well as a certified Water Distribution and Treatment operator. He holds a Bachelor of Sciences Degree in Civil Engineering as well as Masters in Business Administration.
