Frequently Asked Questions
Why is this project needed?
The project is being completed to protect and support the restoration of Hood Canal. The sewer system will provide the backbone of infrastructure required for the Urban Growth Area by the Growth Management Act.
How is this project being funded?
Mason County has secured more than $35 million in funding for the project through federal and state grants, and loans. Operation of the system will be funded through monthly utility bills. See costs for more information.
What will property owners have to pay for?
Connecting to the system does have associated fees that property owners required to connect to the system will be responsible for:
  • There will be a fee to connect to the public sewer. The connection fee is currently estimated at $3,000 per Equivalent Residential Unit (ERU).
  • In addition, it will cost an average of approximately $4,000 to re-plumb your sewer to connect to the main system and disconnect from your septic tank. Sometimes this is referred to as "building a side sewer." These individual costs are property-dependent and will vary.
  • Once the system is operational, the average household can expect to pay an estimated $96 per month for sewer service.
The final rates and fees for connecting to the sewer system will be determined through a rate ordinance, passed by Mason County Commissioners later this year. The final costs will be based on how many properties connect to the sewer system during this first phase.
When will sewer system construction begin and when will it be operational?
Construction is underway and according to our schedule, the system should be operational in 2011. Timelines for side sewer connections are in development.
Where will the wastewater treatment plant be located?
The wastewater treatment plant is being constructed, by Boss Construction, east of the railroad tracks and Romance Hill Road. See Map.
Where will treated water go?
Water will be treated to Class A standards to use for irrigation. See our Facilities Page for more information.
What methods are being used for construction?
To construct the sewer pipes for the conveyance system, Ceccanti, is using both "cut-and-cover" methods, as well as some “trenchless” technologies, including jack & bore and directional drilling. You will see activities around Belfair throughout construction, and traffic may be impacted during some phases. Construction of pump stations and the treatment plant will be site specific, requiring excavation of sites to create the foundation.
