Wastewater Rates and Charges

How Rates are Determined:

Alderwood Water & Wastewater District (the District) has established cost-based fees, rates, and charges to provide sufficient funding to build, operate, maintain, and reinvest in our water & wastewater system that provides our ratepayers with safe and reliable drinking water, wastewater services and fire protection. Every three years the District conducts a cost of utility service study to ensure that our customer classes are paying a rate that approximates the cost of providing them service. Periodically the District adjusts rates within classes so that rates are fair and equitable. .


The chart below compares the District’s monthly sewer charges to neighboring jurisdictions.  The calculations do not include franchise fees or utility taxes imposed by some city utilities.
