Why Does Sioux Falls Use Winter Water Usage to Calculate Part of Your Sewer Bill?

October 20, 2026•2 min read

Quick answer: Sioux Falls uses winter water consumption to estimate the portion of household water that normally returns to the sanitary sewer, avoiding the higher outdoor irrigation use common in warmer months. Homeowners should review the City’s current billing method and contact Utility Billing when a winter-period

Water use and sewer use are related but not identical

Most indoor water eventually enters the sanitary sewer. Summer lawn irrigation usually does not. A winter measurement can provide a more practical baseline than using a high summer water bill.

What the City says

The City addresses the question “Why does Sioux Falls Utilities use winter usage to calculate my sewer bill?” in its Utility Billing FAQs. The exact billing period, rate, account history, and adjustment procedures should be confirmed on the current bill or with Utility Billing.

Why an unusual winter matters

A leaking toilet, extended guests, a temporary occupancy change, construction, or another abnormal event during the measurement period can raise water use. That does not automatically produce an adjustment, but it is a reason to inspect the home and ask the City how the account is calculated.

Use the account tools

Compare current and prior usage rather than only the dollar total. Check for unexplained daily or monthly changes, repair known leaks, save repair documentation, and contact Utility Billing promptly when the data appears inconsistent with the household.
