The Policy Shift
Pennsylvania utility regulators approved PWSA's rate case through a December 2025 settlement, authorizing a 15.5% increase for commercial customers and a 28.2% increase for industrial users, effective March 8, 2026. PWSA had originally filed a multi-year rate proposal in June 2025 seeking substantially larger increases; the settlement reduced the request. The revenue funds debt service obligations, ongoing operations, and critical infrastructure upgrades to Pittsburgh's aging water and sewer systems.
The Math: Commercial Financial Impact
Using verified data from PWSA's rate schedule and ALCOSAN's treatment charges, a commercial facility consuming 300,000 gallons (300 kGal) per month at Pittsburgh's combined volumetric rate of $34.98/kGal (water $16.38 + conveyance $6.68 + ALCOSAN treatment $11.92) currently pays $10,494/month or $125,928/year in volumetric charges alone. After the 15.5% increase, the combined rate rises to approximately $40.40/kGal, pushing monthly volumetric costs to $12,120 and annual costs to $145,440 — a net increase of $19,512 per year. Additional fixed charges (meter fee, PENNVEST, stormwater) add to the total bill.
Mitigation Strategy
Commercial facilities in Pittsburgh should: (1) Audit current water usage to identify waste — even a 10% reduction at the new rate saves $14,544/year; (2) Install sub-metering on cooling towers, kitchens, and irrigation to identify top consumption zones; (3) Consider smart valve technology to enforce consumption caps and reduce metered usage by 15-30%; (4) Review sewer deduction eligibility — water used for cooling, irrigation, or manufacturing that does not enter the sewer system may qualify for conveyance and ALCOSAN charge deductions, saving up to $18.60/kGal on that portion.
