FAQ

Because in Washington, local water, wastewater, and solid waste policies can change the real monthly household total much more than many residents expect. Olympia is easier to compare accurately when those local charges are shown alongside the electric benchmark.
Olympia wastewater includes both the city sewer portion and the regional LOTT treatment charge. That combination makes wastewater one of the largest non-electric utility lines on the bill, even before adding trash and stormwater.
Trash in Olympia is provided by the city as part of municipal utilities and is billed at a monthly fee. Rates and services are set by the local government; our estimate uses the fee from City of Olympia – Rate Information (2026 bi-monthly garbage rates).
We use base charges and per-unit rates from official provider pages. Electric = base + (rate × assumed kWh). Water = base + (rate per 1,000 gal × assumed gallons / 1,000). Sewer is either a flat fee or a percentage of water. Trash is a fixed monthly fee. See the Methodology page for full formulas.
Actual bills depend on your usage, seasonal rates, taxes, fees, and provider-specific rules. Washington is a regulated electric state; our estimates use the serving utility's tariff at 1,000 kWh for comparison.
Each component shows a 'last verified' date. We aim to update from official sources periodically; always confirm current rates on the provider's site before making decisions.
