Maine Water Rates Rising 8–9% for Infrastructure Upgrades — Portland District Leading Increases
Portland Water District is implementing 8.4% and 9.6% increases in 2026. Old Town has already implemented 2% increases. Maine's aging water infrastructure requires substantial investment across the state. Smart Valve™ results vary by site; written terms are available only for qualifying projects.
The Maine Water Situation
Maine's Infrastructure Investment Cycle Means Compounding Rate Increases for Commercial Properties
Maine's water infrastructure — much of it built in the mid-20th century — requires substantial investment to maintain reliability and meet modern standards. Portland Water District is leading the state with 8.4% and 9.6% increases in 2026, and other Maine utilities are following with their own schedules of increases.
Commercial properties in Maine 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.

Portland Water District: Two Increases in 2026 — 8.4% and 9.6%
Portland Water District is implementing two commercial rate increases in 2026: 8.4% followed by 9.6%. These stacked increases in a single year represent a compound increase of approximately 18% for commercial customers in Greater Portland. This is not a one-time adjustment — it reflects a multi-year infrastructure investment program.
Old Town and Statewide Utilities Following Suit
Old Town has implemented 2% increases, and utilities across Maine are implementing their own rate increase schedules as infrastructure investment programs accelerate. Maine's commercial water customers should expect annual increases to continue as the state's water systems modernize.
Aging Infrastructure = Multi-Year Rate Increase Cycle
Maine's water infrastructure investment is not a short-term program. Replacing aging pipes, upgrading treatment facilities, and meeting modern environmental standards is a decades-long commitment. Commercial water rates will continue rising throughout this cycle. Smart Valve™ locks in savings that offset each year's increases.
