Budget & Rate information

Every year, from April through June, Clean Water Services goes through a budget process to establish rates for the following fiscal year. Public meeting notices are published in local newspapers, inviting the public to comment on proposed rates before the budget is adopted. Citizens are welcome to attend the District's Budget Committee meeting in May or to testify before the District's Board of Directors, which ultimately adopts the budget, in June. Before any rate change, the District sends media releases to local newspapers and billing inserts to customers to notify customers of rate increases.

Sewer & Surface Water Management charges for Fiscal Year 2015-16 (July 1, 2015 - June 30, 2016)

Your bill is for sewer and/or Surface Water Management provided to you by Clean Water Services for a two-month period.

Your sewer charge has two parts. The base rate starting July 1, 2015 is $53.26 per dwelling unit, which is approximately two-thirds of the charge. Single family residences are generally considered one dwelling unit.

The usage charge is based on average winter water consumption November through April, which is reviewed and updated each July. Winter water consumption is a good indicator of the wastewater your household produces and discharges into the sewer system for treatment. Beginning July 1, 2015, the usage rate per ccf is $1.77*. New customers will be billed $28.32, based on our average of 16 ccf*.

The Surface Water Management fee is $14.50 bi-monthly per service unit. Single family residences are generally counted as one service unit. Commercial properties are billed based on a measurement of impervious surface area.
