St. Charles Water/Sewer Rates, Bi-Monthly Billing and High Bill Checks
The City says water and sewer services are billed bi-monthly, water meters are read every two months, and water/sewer billing is based on water usage. A high bill may come from real usage, seasonal water use, an internal leak, irrigation or a sewer calculation change.
Bi-monthly bills
St. Charles bills water and sewer every two months, so usage may look larger than a monthly bill.
Tiered water rates
The City says water rates use a consumption-based tiered rate structure to encourage conservation.
Sewer calculation
Residential sewer charges are based on winter water average consumption from the City’s stated winter reading period.
1
Compare the bill to the two-month period
Do not compare directly to a monthly bill from another city.
▾
Because St. Charles bills bi-monthly, compare the usage and charge to the previous St. Charles bill cycle, not a one-month utility bill from another city.
2
Check for hidden household leaks
A leak can affect a full two-month bill.
▾
Check toilets, faucets, outdoor spigots, irrigation systems, water softeners, humidifiers, water heaters and any wet area around the meter or service line.
3
Call billing with useful details
Prepared details reduce repeat calls.
▾
Call 636-949-3212 with your account number, bill period, current balance, payment status, and any leak or repair documentation.
