Updated November 3, 2026 — refreshed with winter freeze-protection protocols, water main-break and pressure-loss procedures, RCW 54.16.285 winter shutoff protections, verified PUD 1 contact numbers, and a property-owner action checklist.
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. For a full line-item breakdown of monthly power charges, see our Mason County PUD 1 electric bill and 2026 rate guide.
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 — see our coverage of Mason County infrastructure updates including PUD 3 fiber and Belfair sewer.
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) 877-5249 (toll-free (800) 544-4223).
2026 Water Rate Schedule Across PUD 1’s 70+ Community Water Systems
On the water side, Mason County PUD No. 1 owns and manages more than 70 separate community water systems (including Group A and Group B systems across Union, Hoodsport, Alderbrook, Arcadia Estates, Canal Mutual, Hamma Ridge, Holiday Beach, Lake Arrowhead, Madrona Beach, Shadowood, Springwood, Twanoh Heights, Twanoh Terrace, and Vuecrest). Following its Cost of Service Analysis (COSA), PUD 1 maintains a uniform monthly base charge and tiered consumption schedule across all district-owned water systems. Per PUD 1’s published 2026 Residential & Small Commercial Water Rate Schedule (revised December 9, 2025, effective January 1, 2026, reflecting a 3.5% water revenue adjustment after grant offsets):
- Base Monthly Charge (First 400 cubic feet or less / First 3,000 gallons or less): $67.93/month
- Tier 2 Volumetric Rate (401 to 1,000 cubic feet / 3,001 to 7,500 gallons): $2.73 per 100 cubic feet ($0.003653 per gallon)
- Tier 3 Volumetric Rate (1,001 cubic feet and above / 7,501 gallons and above): $3.41 per 100 cubic feet ($0.004552 per gallon)
- Unit Conversion Rule: PUD 1 measures water in cubic feet, where 1 cubic foot = 7.48 gallons.
- Key Water Service Fees (2026 Schedule): System Development Fee (new connection buy-in, where capacity is available): $4,733.00 | Service Set-up Charge: $3.00 | Late charge on unpaid balance over 30 days: 1.5% | Smart Meter Opt-Out (manual monthly read): $25.00/month | Non-Pay Disconnect or Field Collection: $75.00 | Working-Hours Reconnect: $75.00 | Non-Working-Hours Reconnect or Customer-Side Outage Check (no charge for utility problems): $300.00.
Winter Operations Layer: Pipe Freeze Protection, Main Breaks & RCW 54.16.285 Shutoff Rules
1. Point of Delivery Boundary & Freeze Protection Protocols
Under PUD 1’s published Water Services policy and Water Policy Manual, the district is responsible for each water system only up to and including the water meter or service valve (if no meter is present), known as the point of delivery. Property owners are prohibited from tampering with or turning water on or off at the PUD’s meter (meter tampering or unauthorized valve operation carries a $200.00 to $250.00 penalty plus a $75.00 reconnect fee). Everything after the meter — including the building supply line from the meter box to the house, customer-side shutoff valves, pressure-reducing valves (PRVs), backflow prevention assemblies, and interior plumbing — is the property owner’s responsibility:
- Locate Your Customer-Side Master Shutoff Valve: Before sub-freezing overnight temperatures hit Hood Canal and rural Mason County, locate and test your customer-side gate or ball valve (separate from the PUD’s street-side meter box) so you can shut off water to the structure immediately if an interior pipe bursts.
- Insulate Exposed Pipes & Backflow Assemblies and Disconnect Hoses: Detach garden hoses, drain outdoor faucets and irrigation lines, and insulate exposed pipes in crawl spaces, unheated garages, pump houses, and above-ground backflow prevention assemblies. Keep the area around the PUD meter box clear and accessible for meter readers and crews.
- Drip Guidance & Why Seasonal Disconnect Beats Running Faucets: PUD 1 does not offer a winter billing credit for continuous faucet dripping on metered accounts. In fact, PUD 1’s Water Conservation guidance notes that a single dripping faucet can waste 20 or more gallons per day — more water in one day than a person needs for drinking in an entire week — pushing metered accounts into the $2.73 and $3.41 per 100 cubic feet consumption tiers. If a home or cabin will sit unheated or unoccupied during winter freezes, use PUD 1’s no-fee Seasonal Disconnect (detailed in the checklist below) so water is shut off at the meter rather than left dripping.
2. What to Do in a Water Main Break, Pressure Loss, or Suspected Freeze Leak
- Reporting a Main Break or Outage: If your water pressure drops suddenly or water service goes out, check whether neighboring parcels are also out and look outside for standing water near the road or meter box. Call PUD 1 immediately at (360) 877-5249 or 1-800-544-4223 (24-hour emergency service) and report your name, service address, and any visible water or sounds. Never assume a neighbor has already called.
- Protect Water Heaters & Prevent Backflow: During a water or power outage, PUD 1 advises tripping the circuit breakers to electric water heaters and space heaters to avoid damaging heating elements or overloading the system when service returns. Because sudden drops in distribution-main pressure can create backsiphonage risk, PUD 1 enforces annual testing of customer backflow prevention assemblies under WAC 246-290-490.
- PUD 1’s 15-Minute Meter Test for Hidden Post-Freeze Leaks: Once temperatures thaw, you can check for a hidden underground or crawl-space leak on your side of the meter using PUD 1’s published meter test: (1) locate your water meter box near the street; (2) turn off all indoor and outdoor faucets and all water-using appliances; (3) record the exact meter reading and wait at least 15 minutes without using any water; (4) read the meter again. If the dial has moved, you have a customer-side leak requiring immediate repair.
- Unduly High Water Bill Leak Adjustment Policy (Water Policy Manual §3.7): If a hidden pipe failure causes a spike on your water bill, Section 3.7 of the PUD 1 Water Policy Manual authorizes the General Manager or designated agent to adjust an unduly high water bill when three conditions are met: (a) the water loss was not reasonably ascertainable by the customer while it occurred; (b) the customer took immediate steps to repair the faulty plumbing upon discovering it; and (c) the customer notified the District promptly so meter readings and repair dates could be documented. Adjustments apply only to excess water charges above the monthly minimum across at most the last three billing periods.
3. Winter Shutoff Protections Under RCW 54.16.285 & Local Utility Assistance
Washington State law (RCW 54.16.285, “Limitations on termination of utility service for residential heating and of electric or water utility service during heat-related alerts”) sets specific statutory rules for public utility districts:
- November 15 – March 15 Residential Space-Heating Moratorium (RCW 54.16.285(1)): A public utility district providing utility service for residential space heating may not terminate that service between November 15 through March 15 if the customer:
- Notifies the utility of the inability to pay within five business days of receiving a payment overdue notice (if the customer misses the five-day window and is disconnected, fulfilling the statutory requirements still restores protection under the chapter);
- Provides household income self-certification for the prior 12 months to the Department of Commerce grantee administering federally funded Low-Income Home Energy Assistance Program (LIHEAP) funds under 42 U.S.C. 8624, which verifies eligibility and calculates the figure equal to 7% of household income;
- Applies for home heating assistance from applicable government and private-sector organizations and certifies that any assistance received will be applied to current and future utility bills;
- Applies for low-income weatherization assistance from the utility or other appropriate agency if available for the dwelling;
- Agrees to and maintains a payment plan designed to pay the past-due bill by the following October 15 and to pay for continued service — where monthly payments between November 15 and March 15 cannot be required to exceed 7% of the customer’s monthly income plus one-twelfth (1/12) of any arrearage accrued from the date application is made and thereafter during that winter window; and
- Agrees to pay the moneys owed even if the customer moves.
- Water Utility Disconnection Rules & Hardship Extensions: Note that under RCW 54.16.285, the November 15 – March 15 statutory moratorium applies to utility service for residential space heating (while the statute’s water utility termination restriction applies during National Weather Service heat-related alerts). For water accounts facing temporary financial hardship in winter, Section 3.6.5 of PUD 1’s Water Policy Manual authorizes the General Manager or designated agent to grant case-by-case payment extensions or partial payment arrangements (generally up to 30 days) when requested prior to the disconnect date.
- Canal Comfort Fund & LIHEAP Agencies (mason-pud1.org/payment-assistance/): Qualifying PUD 1 customers experiencing financial hardship can apply for up to $150 per calendar year from PUD 1’s customer-donated Canal Comfort Fund by calling Customer Service at (360) 877-5249. For LIHEAP income certification and heating assistance appointments, PUD 1 directs customers to:
- Community Action Council of Mason County: 807 W Railroad Ave, Shelton, WA 98584 — (360) 426-9726 (www.caclmt.org)

Property-Owner Action Checklist: Owners vs. Renters vs. Vacant/Seasonal Parcels
For Year-Round Homeowners (Owner-Occupied Properties)
- Shut Off & Insulate Before Hard Freezes: Disconnect garden hoses, insulate exposed crawl-space pipes and backflow assemblies on your side of the meter, and confirm your customer-side master shutoff valve operates smoothly.
- Schedule Annual Backflow Testing: Complete required annual testing of backflow prevention assemblies under WAC 246-290-490 using a DOH-certified Backflow Assembly Tester or by contacting
waterdept@mason-pud1.org/ (360) 877-5249 to have PUD 1 test the assembly and bill your account. - Follow Generator Backfeed Safety Rules: Never plug a portable generator into a household wall outlet during winter windstorms. Either use a professionally installed transfer switch or shut off the main panel breaker and plug appliances directly into the generator placed at least 20 feet outside the home.
- Register Medical Life-Support Equipment: If someone in the household relies on electrically operated life-support equipment, notify PUD 1 at (360) 877-5249 in advance and maintain an emergency backup power plan.
For Landlords & Rental Property Investors vs. Tenants
- File a Rental Standby Agreement: On mason-pud1.org/start-stop-service/, PUD 1 strongly advises landlords to sign a Rental Standby Agreement (Owner/Agent Agreement), which allows the PUD to notify the landlord and keep service active between tenancies if a renter moves out or stops utility service.
- Authorize Tenant Accounts Properly: Landlords must grant permission for new renters to put service in the tenant’s name (requiring a New Customer Application, photo ID, and a $100.00 residential deposit unless waived via an in-house credit check). Under Water Policy Manual §2.3.2, if a tenant uses water without setting up an account and no standby agreement is on file, the landlord is responsible for the charges and the service is subject to shut-off.
- Respect Statutory Landlord-Tenant Utility Protections: Under Washington landlord-tenant law and PUD 1 policy (§2.3.10), PUD 1 cannot disconnect electric or water service because a tenant fails to pay rent to the landlord. Tenants struggling with winter heating bills can establish an RCW 54.16.285 payment plan directly with PUD 1 and Community Action Council of Mason County at (360) 426-9726.
- Allow 5 Business Days for Move-Out Meter Reads: When a tenant or owner moves out, call 360-877-5249 to schedule a stop-service date; PUD 1 has five business days from notice to take the final meter reading.
For Vacant, Recreational & Seasonal Hood Canal Properties
- Request a No-Fee Seasonal Water Disconnect for Winter: Many Hood Canal cabin and recreational parcel owners close up their properties after the summer and early-autumn recreation season wraps up (see our Belfair State Park shellfish and Hood Canal winter off-season guide). Under PUD 1’s Water Services disconnect rules, you can request a Seasonal Disconnect (disconnect for winter and reconnect for summer) at no fee during normal business hours: you continue paying the monthly base charge ($67.93/month), and a PUD serviceman shuts off the water at the meter so interior pipes cannot freeze or flood the structure while you are away.
- Weigh Short-Term vs. Long-Term Disconnect Costs on Vacant Parcels:
- Same-Day Disconnect/Reconnect (for repairs or winterization work): No fee during business hours (8:00 a.m. – 4:30 p.m., Monday – Friday).
- Short-Term Disconnect (reconnecting within 36 months): You do not pay the monthly base charge while disconnected, but the fee to reconnect is the accumulated monthly base rate and capital surcharge for every month the service was disconnected.
- Long-Term Disconnect (more than 36 months): The fee to reconnect is one-half (50%) of the System Development Fee ($4,733.00 full SDF on the 2026 schedule).
- Waitlisted Water Systems Warning: On water systems with connection waiting lists, if a service has been disconnected for more than a year (or if a newly purchased connection is not activated within 36 months), the connection may be reassigned to another parcel. Always call (360) 877-5249 before letting a rural water connection lapse.
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, water leak, or winter outage?
PUD 1 customer service and 24-hour emergency outage dispatch are reachable at (360) 877-5249 or toll-free at (800) 544-4223 (1-800-544-4223). The district office is at 21971 N. Highway 101, Shelton (in Potlatch), WA 98584, with lobby service hours Monday through Friday from 8 a.m. to 4:30 p.m. Board meetings are public and held at 1:00 p.m. on the 2nd and 4th Tuesdays of each month.
