PUD 1 is responsible for each water system up to and including the water meter or service valve (if no service meter) known as the “point of delivery”. The customer is responsible for the water system after the meter including pressure reducing valves, backflow assemblies, fire suppression systems and water leaks.

Water services

To establish water service at your site:

Mason PUD 1’s Water System Finder shows available connections, water system service areas, and WFI numbers for all owned systems. Click here to use the water systems finder to determine if there are available connections. This is for general information and water service is not guaranteed so please call to confirm for your specific site. 

  1. Call the water department to confirm if water connections are available; there is no guarantee water connections are available or will be available in a reasonable amount of time to serve your property. Please review the Water Policy Manual if you are planning to serve more than one residence or commercial property.
  2. Download, print and fill out Section 1 of the Water Adequacy Form, then email, fax (360) 877-5339, mail or hand-deliver form to the water department.
  3. Download, print and return completed Customer Card (SS# not required at this point) to the water department.
  4. Download, print and return completed Water Use Questionnaire (residential) or Preliminary Cross Connection Control Hazard Assessment Form to the water department.
  5. PUD 1 will create and send you an invoice for new service including:
    • System Development Fee, which is your fee to buy into the water system
    • Meter Installation Fee (at cost, plus tax)
    • Cost to extend service to property, if applicable
    • Cost to install backflow assembly, if applicable
  6. Pay invoice
  7. PUD 1 will submit Water Adequacy to Mason County
  8. PUD 1 will install meter and set up new account
  1. Call Customer Service Representative to determine requirements for having service reconnected at the particular address even if you are purchasing the property.
  2. Fees may be required to reconnect the water service. These are not “past due” fees, these are fees to have the water turned back on.
  3. There is no guarantee that water connections will still be available to allow the service to be reconnected. Some systems have waiting lists for connections; if a connection has been disconnected for more than a year, it may be re-assigned to another parcel.
  4. If you are building on vacant land or are otherwise required by Mason County, download, print and fill out Section 1 of the Water Adequacy Form then email, fax (360) 877-5339, mail or hand-deliver form to the water department.
  5. For new customers having a property’s service reconnected – download, print and return completed Customer Card (SS# not required) to Customer Service.
  6. For new owner or tenant having a property’s service reconnected – download, print and return completed Water Use Questionnaire (residential) or Preliminary Cross Connection Control Hazard Assessment Form (non-residential) to the water department.
  7. DOH now requires meters to be installed on all Group A service connections; you may be required to pay a Meter Fee (at cost plus tax) to have a meter installed on an existing connection
  • Same Day (disconnect/reconnect same day, no fee during business hours) usually done for repairs or customer’s modification to service
  • Seasonal (disconnect for winter and reconnect for summer, no fee) – continue to pay monthly base rate and capital surcharge, but water is shut off so pipes do not freeze or leak during long absences
  • Short Term (reconnect within 36 months after disconnect) – do not pay monthly base rate – the fee to reconnect is the monthly base rate and capital surcharge for each month the water was disconnected
  • Long Term (reconnect more than 36 months after disconnect) – fee to reconnect is one-half of the system development fee for that water system
  • Non-Pay –
  1. If the original customer is reconnecting, the previous amount owed, late fees, deposit and other fees may be due in order to reconnect service.
  2. If a new customer is reconnecting the service, the short-term or long-term reconnection policies above will apply.
  3. Disconnection due to failure to meet cross connection control requirements – installation and testing of a backflow device will be required, plus short term or long term reconnection fees.

The Cross Connection Control Program is implemented to reasonably reduce the risk of contamination to the District’s distribution systems and to reasonably reduce the District’s exposure to legal liability arising from the backflow of any contaminant originating from a customer’s plumbing system and then supplied to other customers.

All new residential customers are required to fill out and return a completed Water Use Questionnaire and all new non-residential customers are required to fill out and return a completed Preliminary Cross Connection Control Hazard Assessment Form. Also, fill out one of the forms if you are modifying the use of the property or remodeling.

Your form will be evaluated and one of our Cross Connection Control Specialists may call you to schedule an inspection of your property to determine the type of backflow protection required on your service. Backflow protection assemblies are required to be tested annually.

A list of Dept. of Health-approved backflow assembly testers is provided here so you may choose the tester for your needs. As a convenience, you may contact the water department to schedule the District to annually test your device and invoice you for the testing.

A list of DOH-approved backflow assembly testers can be found here. Alternatively, you can contact the water department and arrange for the PUD to perform your annual assembly testing and invoice you for the service.

If you would like to be added to our approved Backflow Assembly Tester list that is provided to our customers, please provide a current BAT certification and calibration to the Water Department at [email protected] or by mail to the PUD’s mailing address.
