If you own property in Mason County that draws water or electricity from Public Utility District No. 1, spring 2026 brings two concrete developments: a major rural water infrastructure cycle closing out, and an electric rate increase that took effect April 1 — one that district staff managed to keep lower than originally authorized.
Two Rural Water Systems Brought Up to Standard
Mason County PUD No. 1 reported at its April 14, 2026 board meeting that the Manzanita Water Storage Project and the Arcadia Estates water system upgrade are both reaching completion. For property owners in and around those service areas — communities along the southern Hood Canal shoreline, Union, and rural Hoodsport — this represents the end of a multi-year capital investment cycle that directly affects property infrastructure reliability.
The Manzanita project carried total construction funding of $4.6 million, with the storage tank contract of $3,745,725 awarded to Rognlin’s Inc. of Aberdeen in June 2025. Construction began in September 2025 and reached close-out reporting by the April board meeting. The Arcadia Estates system upgrade was completed in the same reporting window. These are not cosmetic improvements — they are foundational upgrades to the water storage and distribution systems that serve rural residential customers whose properties depend on PUD 1 service for potable water.
For property owners, updated water infrastructure is a material factor in property condition and insurability. Aging rural water systems carry risk of service disruptions, pressure inconsistencies, and compliance issues. PUD 1’s investment in these systems reduces that risk profile for affected properties.
PUD 1 has also submitted a $5.6 million Congressionally Directed Spending request — a federal appropriations mechanism — to fund the next phase of rural water system improvements. If awarded, it extends the district’s infrastructure investment without corresponding local rate increases, which is relevant to property owners watching the long-term cost trajectory of utility services in the county.
April 1 Electric Rate Increase: 3.0% — Here’s the Math
Effective April 1, 2026, the residential basic monthly charge increased from $45.86 to $47.26. The energy rate moved from $0.09670 to $0.09960 per kilowatt-hour. The net effect on a typical residential bill is approximately 3.0%.
The cost driver is external: the Bonneville Power Administration raised its power rate by 6% and its transmission rate by 11.7% for 2026. PUD 1, like most public utility districts in Washington State, buys wholesale power from BPA and must pass through a portion of those increases. What’s notable is what PUD 1 held back — the district originally had board authorization for a larger increase, but secured a federal emergency management grant that allowed them to reduce the rate adjustment to 3.0% rather than implementing the full authorized amount.
For property owners with rental units, vacation properties, or investment parcels in Mason County, the 3.0% increase is modest. On a property drawing 800 kWh per month, the monthly cost increase is approximately $2.65 — about $32 per year. Properties with higher draws (electric heat, water pumps, outbuildings) will see proportionally more, but the rate structure remains among the more affordable in the Puget Sound region.
What PUD 1 Serves — and What It Doesn’t
Property owners in Mason County sometimes confuse the three PUDs operating in the county. PUD No. 1 provides electric service to customers across Mason County and also operates rural water systems in specific communities — Shelton, Hoodsport, Union, and areas along the Hood Canal south shore. It is not the same district as PUD No. 3, which serves different territory and recently made news for its fiber internet buildout.
If your property is on a PUD 1 water system and you are uncertain whether the Manzanita or Arcadia Estates project areas are adjacent to your parcel, the district’s customer service line can confirm service area boundaries. PUD 1 is located at 21971 N. Highway 101, Shelton, WA 98584. The main contact number is (360) 426-8255.
Frequently Asked Questions — PUD 1 for Mason County Property Owners
What is the new PUD 1 residential electric rate as of April 1, 2026?
The basic monthly charge is now $47.26 (up from $45.86) and the energy rate is $0.09960 per kWh (up from $0.09670). The overall increase on a typical residential bill is 3.0%, less than the originally authorized amount because the district secured a federal grant to offset the increase.
Did PUD 1 complete the Manzanita water project?
Yes. The Manzanita Water Storage Project reached close-out reporting at the April 14, 2026 PUD 1 board meeting. Total construction funding was $4.6 million, with the primary contract awarded to Rognlin’s Inc. of Aberdeen. The Arcadia Estates water system upgrade was also completed in the same reporting cycle.
Why did my PUD 1 electric bill go up if PUD 1 is a public utility?
PUD 1 purchases wholesale power from the Bonneville Power Administration, which serves most Pacific Northwest public utilities. BPA raised its power rate 6% and transmission rate 11.7% for 2026, forcing PUD 1 to pass through a portion of that increase. The district reduced its own rate adjustment to 3.0% by securing a federal emergency management grant.
Does the $5.6 million federal funding request affect my PUD 1 rates?
If awarded, the $5.6 million Congressionally Directed Spending request would fund additional rural water system improvements without requiring a corresponding rate increase. It is a pending federal appropriations request, not yet approved, but it represents PUD 1’s strategy for continuing infrastructure investment while managing customer rate impacts.
How do I contact Mason County PUD 1 about my service area or property?
PUD 1 customer service is reachable at (360) 426-8255. The district office is at 21971 N. Highway 101, Shelton, WA 98584. Board meetings are public and held monthly — the April 14, 2026 meeting is when the Manzanita and Arcadia project completions were formally reported.
