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
