FAQ

Marietta Power and Water is a city-owned utility, and Marietta's public pages confirm rates are being held steady for 2026. This page uses the Georgia PSC's current residential comparison survey to anchor the 1,000-kWh electric estimate until the city exposes a full current residential tariff table in a cleaner public format.
Because Georgia household utility bills are rarely just about electricity. Local water, wastewater, and solid waste charges can add a large fixed or semi-fixed monthly cost, which is why the total utility picture is usually more helpful for relocation and budgeting than the power line alone.
In Marietta, 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 Marietta - Water & Wastewater Consumption Fees (effective January 1, 2026) at the assumed 5,000 gallons per month. Your bill will vary with actual usage.
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.
