Kelseyville Wastewater Treatment
The Kelseyville wastewater collection and treatment facility was constructed in the late 1960s. The collection system serves the downtown and surrounding residential areas of Kelseyville. Wastewater from the Clear Lake State Park was added during the 1970s and the wastewater collection system of Corinthian Bay (AD 9-2) was added in the 1980s.
Middletown Wastewater System
Based on the results of a 1987 study sponsored by the Lake County Environmental Health Department, the Board of Supervisors adopted a moratorium on new septic systems and Assessment District 2-2 (AD 2-2) was established for the purposes of constructing a wastewater collection and treatment facility. The Middletown wastewater collection and treatment facility was constructed and started serving the downtown and surrounding residential areas of Middletown in 1992.
Northwest Regional Wastewater System
The Northwest (NW) wastewater collection system serves the communities of North Lakeport, Upper Lake, Nice, Lucerne, Kono Tayee, and Paradise Valley. Many portions of the collection system were constructed 25 to 30 years ago when construction standards and materials were not as comprehensive as they are today. Due to the age of the collection system, the close proximity to the lake, and seasonal high lake levels, Inflow and Infiltration (I/I) are common and contribute to a large percentage of winter flows.
South Lakeport Wastewater Service
The South Lakeport wastewater collection system serves customers in AD 9-1 and AD 9-3, from Lands End and portions of the Big Valley Rancheria, Soda Bay Road, and South Main Street. Raw wastewater is conveyed through a series of lift stations and the collection system. The wastewater is treated at the City of Lakeport’s Wastewater Treatment Facility through a formal agreement between the two agencies.
Southeast Regional Wastewater System
The Southeast (SE) system collects and treats wastewater in the Clearlake area. The collection system extends from Pirates Cove to Lower Lake and includes the City of Clearlake. Portions of the collection system were constructed over 30 years ago when materials, construction techniques, and inspections were not as advanced and comprehensive as they are today.
