Two infrastructure decisions are shaping Mason County’s future right now — one with a hard deadline in 23 days, the other with a clock that starts only when Bremerton writes a check. If you live along the Cloquallum Road corridor, the May 31 deadline is the most time-sensitive infrastructure opportunity your neighborhood has seen in years. If you’re a Belfair resident or business owner, the Bremerton sewer agreement is worth watching closely through the rest of 2026.
Act Before May 31: Free Fiber Applications Closing on Cloquallum Road
More than 680 homes and businesses along the Cloquallum Road corridor in north Mason County are now eligible to apply for high-speed gigabit fiber internet — and the window to do it for free closes May 31, 2026.
Mason County Public Utility District No. 3 completed the mainline network for the Cloquallum Communities Fiberhood on February 10, 2026, connecting the Wivell Road, Loertscher Road, and Cloquallum Fiberhoods areas to the PUD 3 backbone. Now PUD 3 is collecting construction applications from individual property owners — the step that triggers installation of the final drop connection to each home or business.
The fee PUD 3 normally charges for that construction application is $250. That fee is waived entirely through May 31, 2026. After that date, anyone who applies pays the full $250 upfront, no exceptions. PUD 3 has set this deadline to give the project’s contractor a firm installation schedule — once the application window closes, crews begin sequencing drops along the corridor.
The upgrade these applications unlock is substantial. Current broadband speeds in the Cloquallum Road area run roughly 1.5 Mbps on legacy infrastructure — barely enough for a single video call. PUD 3’s gigabit fiber delivers 1,000/1,000 Mbps symmetrical speeds, among the fastest residential broadband available in Washington state. Monthly service through PUD 3’s open-access fiber network runs approximately $85 per month.
That “open access” model is important to understand. PUD 3 builds and owns the physical fiber infrastructure, but multiple retail internet service providers can offer service over the same cable. Residents choose their provider — and can switch without a new installation. The model has already connected more than 3,000 homes and businesses across Mason County through prior PUD 3 Fiberhood builds, including the Three Fingers project completed in early 2026.
The Cloquallum project was funded in part through an American Rescue Plan Act grant awarded to PUD 3 by the Washington State Broadband Office in late 2023. Phase 1 wrapped in July 2025, bringing fiber to the Lake Arrowhead, Star Lake, Bulb Farm, and Lost Lake areas near Cloquallum Road. Phase 2 — the current application round — covers Wivell Road, Loertscher Road, and the broader Cloquallum Road Fiberhood running from west of Bear Trap Boulevard east toward Rock Creek Road.
Property owners who have received a PUD 3 announcement letter should apply immediately at pud3.org. Those in the project area who have not received a letter should contact PUD 3 directly to verify eligibility before May 31.
Belfair Sewer: Bremerton Must Pay Before the Study Starts
About 20 miles to the south, Mason County commissioners signed off in February 2026 on a revised memorandum of understanding with the City of Bremerton regarding potential sewer service to the Puget Sound Industrial Center — a business corridor in north Belfair. The key revision: Bremerton must pay Mason County’s share of a comprehensive feasibility study before any work begins.
Under the updated MOU, both parties agreed to a full feasibility study including preliminary engineering and a financial evaluation of capital, operational, and long-term costs. The study must be completed within 180 days of Bremerton’s payment. Commissioners then have 90 days to determine whether proceeding is in the best interest of county ratepayers.
The context matters. The Belfair Wastewater Reclamation Facility has carried a documented structural concern — a suspected sinkhole first flagged by the Washington State Department of Ecology in 2016 — that the county has not fully remediated. Extending capacity to serve Bremerton’s industrial interests while that issue remains open drew significant debate when commissioners considered the original agreement. The revised MOU requires Mason County to consult with the Squaxin Island Tribe before any final decision on expansion, given that the Belfair WWRF sits within the tribe’s usual and accustomed fishing area and any expansion carries potential implications for salmon habitat in Coulter Creek.
If Bremerton pays, the study clock starts and a 180-day analysis begins. If Bremerton does not pay, the question of Belfair’s long-term wastewater capacity remains unresolved indefinitely. Mason County residents and businesses near the Belfair sewer system can track developments at the Belfair Sewer Advisory Committee page.
What to Watch
For Cloquallum Road area residents: May 31 is a firm deadline with a real dollar amount attached — $250 saved or $250 spent, depending on when you submit your application. Visit pud3.org or call Mason County PUD No. 3’s Shelton office to confirm your eligibility and get your application in.
For Belfair: the sewer story moves at Bremerton’s pace for now. The next trigger is Bremerton initiating payment — at that point a 180-day clock begins, and public briefings, commissioner sessions, and Belfair Sewer Advisory Committee meetings will become the venues to watch.

Frequently Asked Questions
What is the May 31, 2026 deadline for PUD 3 Cloquallum fiber?
Mason County PUD No. 3 has waived the standard $250 construction application fee for property owners in the Cloquallum Road corridor Fiberhood areas through May 31, 2026. After that date, the full $250 fee applies to any new application. Submitting before the deadline locks in free installation processing for eligible homes and businesses in the Wivell Road, Loertscher Road, and Cloquallum Road Fiberhood areas.
How fast will PUD 3 Cloquallum fiber internet be?
PUD 3’s gigabit fiber delivers symmetrical 1,000/1,000 Mbps speeds — meaning 1 Gbps both downloading and uploading. Current legacy broadband speeds in the Cloquallum Road corridor run approximately 1.5 Mbps. Monthly service through PUD 3’s open-access network costs approximately $85 per month, with multiple retail internet service providers available to choose from on the same fiber infrastructure.
Who is eligible for the Cloquallum Communities Fiberhood application?
Property owners and tenants in the Wivell Road, Loertscher Road, and Cloquallum Road Fiberhood areas of north Mason County are eligible. PUD 3 mailed announcement letters to eligible addresses. If you live in the project area and did not receive a letter, contact Mason County PUD No. 3 directly through pud3.org to verify your address’s eligibility before the May 31 deadline.
What is the Belfair sewer MOU with Bremerton about?
Mason County commissioners revised a memorandum of understanding with the City of Bremerton in February 2026 regarding potential sewer service to the Puget Sound Industrial Center, a business corridor in north Belfair. The revised agreement requires Bremerton to pay upfront for a comprehensive feasibility study — including preliminary engineering and financial analysis — before any expansion work begins. If Bremerton pays, the study must be completed within 180 days; commissioners then have 90 days to decide whether to proceed.
Will the Bremerton sewer deal increase rates for existing Belfair customers?
No decision on sewer service expansion has been made — the feasibility study (which Bremerton must fund) is the first step. The study will evaluate financial impacts including capital, operational, and long-term costs to Mason County. Commissioners are required to determine whether proceeding is in the best interest of current county ratepayers before any expansion agreement can move forward. Ratepayer impact will be a central issue in those deliberations.
Why does the Belfair sewer expansion require tribal consultation?
The Belfair Wastewater Reclamation Facility sits within the usual and accustomed fishing area of the Squaxin Island Tribe. Any expansion of the system has the potential to affect salmon habitat in Coulter Creek. Under the revised MOU, Mason County is required to consult with Squaxin Island Tribe representatives before making any final decisions on sewer service expansion to the Puget Sound Industrial Center.
