Seattle Public Utilities uses a tiered rate structure that punishes high consumption. Residential customers pay progressively higher rates as usage climbs, meaning inefficient homes face exponential cost increases rather than linear ones. This pricing model aims to reduce strain on regional water sources and protect salmon habitat in watersheds feeding the Cedar River and South Fork Tolt River supplies. Additionally, Seattle's combined sewer system in older neighborhoods routes both wastewater and stormwater through the same pipes. During heavy rain, overflows discharge into Puget Sound. Reducing indoor water use decreases wastewater treatment demand and eases pressure on this aging infrastructure. Every gallon you save reduces both your bill and your environmental footprint.
