History of District

In 2006, South Placer Municipal Utility District celebrated 50 years of service to its customers. Local community leaders from Rocklin and Loomis started a grassroots effort in the early 1950’s to provide sewage collection and treatment services for the urban areas of the Loomis Basin. On September 24, 1956, the Rocklin-Loomis Municipal Utility District (RLMUD) was established under the State of California Municipal Utility District Act.

At its inception, the District covered an area of approximately 4,200 acres and had 452 connections. In 1987, the District changed its name to South Placer Municipal Utility District (SPMUD) to reflect its larger service area. Since 1980, the District has experienced an average annual growth rate of approximately 6.5 percent. Currently, the District service area covers approximately 16,700 acres with 18,636 connections, representing 27,666 Equivalent Dwelling Units (EDU’s).

Initially, the District provided sewage treatment in several sewer treatment lagoon systems, at various sites within the service area. These lagoons were decommissioned in 1974, when the Roseville Trunk Sewer was built to convey the sewage to the Roseville Dry Creek Wastewater Treatment Plant (DCWWTP). At that time, the District entered into a service agreement with the City of Roseville for the treatment of the RLMUD sewage. The District continues to provide for the administration, financing, engineering and construction functions, and the operation and maintenance of the sewer collection system.

In October 2000, the South Placer Wastewater Authority (Authority) was created by the City of Roseville, Placer County, and South Placer Municipal Utility District (the Members) to finance the construction of a second regional treatment plant called the Pleasant Grove Wastewater Treatment Plant (PGWWTP) and other improvements located in the City of Roseville. The Authority issued $180 million of debt in December 2000 for the construction of the PGWWTP, along with other regional improvements. Construction costs were reimbursed from bond proceeds and the PGWWTP was completed for the most part at the end of fiscal 2005. Connection Fees collected from developers are used to fund the cost of the debt service on the Plant’s construction, including principal and interest. The Authority is responsible for collecting contributions of Connection Fees from the Authority’s members and for making all debt service payments on the Revenue Bonds until they are retired. Under the terms of the agreements creating and governing the Authority, the capital improvements are transferred to the City of Roseville, which will own and operate the improvements when they are complete.
