Sioux Falls's Water Use Rules: The Rules That Matter

Every city handles water use rules a little differently. In Sioux Falls, South Dakota, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Recycled Water Rules

Sioux Falls does not operate a purple-pipe recycled water system; treated effluent from the Water Reclamation Plant discharges to the Big Sioux River under SD DANR permit rather than supplying irrigation customers.

Key details: Recycled network: None. Effluent discharge: Big Sioux River. Permit type: NPDES. Future plans: Exploratory only.

There are no enforcement provisions because there is no recycled-water system; unauthorized cross-connections to potable mains are addressed under separate backflow prevention rules.

If you are coming from a city with tighter rules, you will find Sioux Falls gives residents more flexibility on recycled water rules.

Leak Reporting Duty

Sioux Falls Water Utility offers one-time bill adjustments for documented underground leaks repaired within 30 days, and customers can report main breaks or hydrant leaks 24/7 through dispatch at 605-367-8000.

Key details: Adjustment frequency: Once per account. Repair window: 30 days. Dispatch number: 605-367-8000. Documentation: Plumber receipt required.

There are no penalties for reporting; failure to repair a known customer-side leak within 30 days voids the adjustment offer and may lead to high-usage surcharge billing.

Sioux Falls is more permissive than most cities when it comes to leak reporting duty. That said, there are still limits.

Turf Replacement Rebates

Sioux Falls does not offer rebates for replacing lawns with native plantings or rock; voluntary conversions are permitted under landscaping rules but receive no city financial incentive given ample regional water supply.

Key details: Rebate amount: None offered. Native plantings: Allowed. HOA override: Aesthetics only. Code reference: Ch. 95 maintenance.

There are no penalties for voluntary conversions; unmaintained replacements that produce noxious weeds may trigger Ch. 95 weed-cutting orders with abatement billing.

Sioux Falls is more permissive than most cities when it comes to turf replacement rebates. That said, there are still limits.

Lawn Watering Restrictions

Sioux Falls Water Utility uses an odd-even sprinkling schedule from May through September, restricting outdoor irrigation between 10 a.m. and 6 p.m. to protect aquifer supply from the Big Sioux Aquifer.

Key details: Restricted hours: 10 a.m. to 6 p.m.. Schedule: Odd-even by address. New sod variance: 21 days. First fine: 100 dollars.

First violation is a written warning; second offense within 12 months brings a 100 dollar fine; chronic violators face water service surcharges and possible shutoff after notice.

The Bottom Line

Compared to many U.S. cities, Sioux Falls gives residents more room on water use rules. 3 of the 4 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.
