How are Rates 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 and 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.

Regional Comparisons

Regional water and wastewater comparisons were done in August of 2022 and do not reflect changes since then. The average household within the Alderwood Water & Wastewater District consumes 7 Centum Cubic Feet or 5236 gallons per month. The below graphs show what a typical household within the Alderwood Water & Wastewater District would pay if they used the same amounts for water and wastewater.

Wastewater rates are higher because it is more expensive to treat raw sewage. Learn more about how we keep our region and communities healthy and environmentally sustainable on our wastewater recovery page.
