Average Water and Sewer Bill Monthly 2026: Usage & Cost

Combined water + sewer for a family of four is typically $110–$150 nationally, $80–$135 in low-cost Midwest/Southern cities, and $150–$290 in high-cost arid West or old-infrastructure Northeast cities.

EPA-mandated combined sewer overflow and stormwater projects are typically funded exclusively on the sewer side, which can push sewer rates 50-100% above water rates in affected cities.

Only for high-usage households. If you are a conservative 1-2 person household, the $40/mo flat charge a landlord wraps into rent is often higher than what you would pay on a submeter.

Silent running toilet flapper leaks. A single bad flapper can waste 200-2,000 gallons a day, adding $15–$60+ to the monthly bill before you ever see a puddle on the bathroom floor.
