Sewer Rate Studies

Fresh Look at Calculating Sewer Charges

In fiscal year 2012/13 the District completed a residential customer Sewer Service Allocation Study. Based on the study results, for fiscal year 2013/14 the Board has elected to keep the residential single family sewer service charge as approved under the 2010 rate plan. Additionally, the Board has elected to reduce the residential Floating Home and Multi-family customer class sewer service charge rates.

The change in the sewer rate structure allows the District to recognize differences in wastewater flow between the three residential customer classes. Under the new structure, a fixed component per EDU consisting of 88% of the revenue is combined with a volumetric component recovering 12% of the revenue from flow, based on flow differences among customer classes. Customers in each respective residential class have the same charge (Single Family, Multi-family and Floating Homes).

The Board has requested that additional analyses be completed during FY 2013-14 that could lead to further adjustments in the rate structure, which includes correcting the resulting revenue shortfall. The additional analysis will build on work completed to better understand certain aspects of the study information related to customer service and District finances.

The District will continue to ensure that information is made available as the study unfolds through mailings, the press, public meetings, and the web.
