South Dakota Water Rates Rising — Drought Conditions and Infrastructure Investment Drive Increases
Sioux Falls is raising commercial water rates 3.5% in 2026. Rapid City raised sewer rates 10% for 2025.

AWS reports average savings just above 22% across its North American projects. Individual results vary.
The South Dakota Water Situation
South Dakota's Commercial Properties Face Drought-Driven Rate Increases Across Both Major Markets
South Dakota's two largest commercial markets — Sioux Falls and Rapid City — are both implementing commercial water and sewer rate increases in the 2025–2026 cycle. Drought conditions are reducing groundwater availability and forcing infrastructure investment that is funded through commercial rate increases.
Commercial properties in South Dakota may have site-specific water-system and billing considerations. Smart Valve™ assessment and installation planning is based on the property's actual setup, billing history, and local requirements. Published project results vary by site and measurement period.

Rapid City: 10% Sewer Increase in 2025 | Sioux Falls: 3.5% Water in 2026
Rapid City raised commercial sewer rates 10% for 2025 — one of the steeper single-year increases in the state. Sioux Falls is raising commercial water rates 3.5% in 2026, reflecting ongoing infrastructure investment. Both increases compound on previous years' adjustments.
South Dakota Drought Straining Groundwater Availability
South Dakota is experiencing drought conditions that are reducing groundwater levels across the state. As natural water availability decreases, utilities invest in alternative sources, deeper wells, and expanded treatment capacity. Commercial customers fund this investment through rate increases that will continue as drought conditions persist.
Agricultural Competition for Water Resources
South Dakota's extensive agricultural sector competes with commercial and municipal water users for limited groundwater resources. As agriculture intensifies, municipal water managers face pressure on both supply volume and quality — pressure that translates to commercial rate increases as utilities invest in water security.
