Ukiah Valley Sanitation District

151 Laws Avenue,

Ukiah CA, 95482

(707) 462-4429



The District does not have operations staff of its own; it therefore contracts with the City of Ukiah for the provision of wastewater services. The City has its own staff, equipment and facilities for management and operations of wastewater services within the City’s jurisdiction. Under a contract known as a Participation Agreement both agencies are able to operate together in a unified manner to provide wastewater services to their respective jurisdictions.

The current Participation Agreement was finalized in July of 1995. In March of 1999, an amendment was agreed to by both agencies (Amendment No. 1) and following that in December of 2004, Amendment No. 2 was adopted by both agencies. Collectively, the 1995 Agreement and Amendments 1 & 2 contain the entire Agreement between the City and the District concerning the City owned Waste Water Treatment Plant (WWTP) and the City’s operation of the sewer system for the City and the District.  The term of the Agreement was for thirty years allowing either the City or the District to cancel upon five years notice.

The Participation Agreement specifies that the annual costs of the entire sewer system (WWTP and collection system) be apportioned between the City and the District each year according to the ratio of Equivalent Sewer Service Units (ESSUs) utilized between the two entities. Annual costs includes treatment, maintenance, operation, administration, repair and replacement, expansion, upgrading, debt service, insurance and financial services for the system.

Under this Agreement, the District is required to establish rules and regulations necessary for the orderly administration of the District’s collection system. These rules and regulations are to include the use of the sewers, the installation of sewer laterals and mains and the discharge of wastewater into the collection system. The District is also required to establish fees and charges for use of the system to include connection fees, service fees and capacity charges. Additionally, the District is required to establish fees for permits and inspection sufficient to reimburse the City for its actual of performance of these services.

The City is the paying and receiving agent for all District operation and maintenance funds. It therefore provides the monthly billing to service recipients and receives payments for the billings. The City is also responsible for the initial preparation of the proposed annual budget for the system which must receive approval from the City Council and the Board of Directors of UVSD.
