FAQ

In Ottumwa, sewer is billed in tiers based on usage, so the rate per gallon changes with volume. Our estimate uses the rate structure from City of Ottumwa – Ord. 3243-2025 sewer eff. July 1, 2026 ($20.65/mo + $6.79/100 cf) at the assumed 5,000 gallons per month. Your bill will vary with actual usage.
Trash in Ottumwa 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 Ottumwa – Ord. 3242-2025 solid waste ($24.50/mo; $26 eff. July 1, 2026).
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. Our estimates use fixed assumed usage (e.g., 1,000 kWh, 5,000 gal) for comparison. Your home may use more or less.
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.
