The Policy Shift
Effective January 1, 2026, Minneapolis Public Works raised sanitary sewer rates from $5.33 to $5.92 per CCF — an 11.1% increase — while water rates ticked up just 1%, from $3.84 to $3.88 per CCF. Fixed monthly service charges saw an even sharper spike: water meter fees rose 44% (from $8.15 to $11.75) and sewer base charges increased 14% (from $8.15 to $9.30). The rate adjustments reflect rising treatment costs, aging infrastructure demands, and increased charges from the Metropolitan Council Environmental Services (MCES), which handles regional wastewater treatment for the Twin Cities metro area.
The Math: Commercial Financial Impact
Using integer-math calculations against verified 2026 Minneapolis rate schedules, a commercial facility consuming 300 kGal/month (typical for a mid-size office complex, hotel, or restaurant cluster) faces: Sewer volumetric increase of $2,808/yr — this single line item accounts for 91% of the total delta. Water volumetric increase of $216/yr. Fixed charge increase of $57/yr. Total verified annual operating expense increase: $3,081. The combined effective volumetric rate rises from $12.26/kGal to $13.10/kGal — a 6.9% increase that compounds annually if the trend continues.
Why the Sewer Side Matters More
Minneapolis commercial sewer charges are based on 100% of metered water consumption year-round — unlike residential accounts that get a winter-average cap. This means every gallon of water consumed by a commercial facility triggers the full $7.91/kGal sewer charge with no seasonal relief. For water-intensive facilities like restaurants, breweries, data centers, and car washes, the sewer component can exceed 60% of the total utility bill. The 11.1% sewer hike disproportionately impacts these high-consumption verticals.
Mitigation Strategy
Commercial facilities in Minneapolis should audit their water consumption immediately. Key strategies include: (1) Install sub-meters to identify and fix hidden leaks — even a 10% leak reduction at 300 kGal/month saves $4,716/yr at the new combined rate. (2) Evaluate cooling tower water treatment and blowdown cycles — optimizing cycles of concentration from 3x to 5x can reduce makeup water by 25%. (3) Consider air compression valve technology for domestic water systems, which can reduce metered consumption 15-30% without affecting water pressure or flow. (4) Review sewer discharge agreements — some facilities may qualify for reduced sewer rates based on water consumed but not discharged (e.g., irrigation, evaporative cooling).

What is the new commercial water and sewer rate in Minneapolis for 2026?
As of January 1, 2026, Minneapolis commercial water rates are $3.88 per CCF ($5.19/kGal) and sewer rates are $5.92 per CCF ($7.91/kGal), for a combined volumetric rate of $13.10 per 1,000 gallons. Monthly fixed charges are $11.75 for water and $9.30 for sewer on a 5/8-inch meter.
How much did Minneapolis sewer rates increase in 2026?
Minneapolis sanitary sewer rates increased 11.1% in 2026, rising from $5.33 to $5.92 per CCF ($7.13 to $7.91 per 1,000 gallons). For a commercial facility using 300,000 gallons per month, this sewer increase alone adds $2,808 per year to operating costs.
How much more will a Minneapolis commercial property pay for water in 2026?
