DISTRICT FORMATION AND AUTHORITY

The Union Sanitary District is an independent special district which provides wastewater collection, treatment and disposal services to the residents and businesses of the cities of Fremont, Newark and Union City, in Southern Alameda County, California. Independent special districts are voted into existence by the citizens they serve and are sanctioned under California law to perform specific local government functions within certain boundaries. The District was formed in 1918 and reorganized under the Sanitary District Act of 1923. It derives its authority in the California Health & Safety Code (Sections 6400-6830). The District is governed by an elected Board of Directors which is accountable to the public. The Directors are members of the community they represent. The District recovers the cost of their service delivery through rates imposed on users of the service. The District is independently audited and subject to state and public scrutiny.

Other special districts in Alameda County provide services such as water, fire service, mosquito abatement, recreation, parks and hospital services
