Why is my water bill so high in Seattle?

A practical, Seattle-specific checklist: how your bill is built, what usually drives spikes here, and the quickest ways to find your fix.

How Seattle Public Utilities bills work

Seattle's combined water-sewer bills run high for the volume used, and peak-season rates make summer gallons pricier than winter ones. Sewer charges track your water use, doubling the cost of every wasted gallon.

Rates and schedules change — always confirm current numbers on the official Seattle Public Utilities site.

The usual suspects in Seattle

  • Running toilets and dripping fixtures — indoor leaks dominate in a city with modest irrigation.
  • Old service lines and fixtures in Seattle's older housing stock.
  • Summer garden watering hitting peak-season pricing.

Because sewer rides on water usage, fixing one leak saves you twice on the same bill.
