Lake County Sanitation District (LACOSAN or District) provides sewer service to Middletown, California in southern Lake County. The Middletown Wastewater Treatment Plant (WWTP) is located adjacent to Putah Creek, approximately two miles west of downtown Middletown at 20126 Highway 175. The WWTP service area includes the sewered portions of Middletown and Harbin Hot Springs. The WWTP and associated sewer collection system were placed into service in 1992 to provide its service to downtown Middletown businesses and residences.
The purpose of the analysis was to conduct a rate study which evaluates the District’s current rates and financial data, and propose new rates if necessary that meet the District’s financial and strategic goals.
Linked below are the Financial Planning Revenue Requirements and Rate Setting Analysis document as well as the Public Notice for the Public Hearing to consider a sewer rate increase. If you have questions concerning either of these documents or the process in general please contact Jesse Salmeron, Deputy Administrator – Fiscal, or Scott Harter, Administrator at our administration office.
