Water Service Line Identification Form

Water suppliers in Washington State are required to compile a complete inventory of drinking water service line materials used throughout the water system by the end of 2024. This includes district-owned and customer-owned service lines that will be one of three to four different types of materials. The drinking water service line is the pipe that runs from the water meter at your property to your residence, as shown in the illustration below.

Completing the step-by-step form below will help determine your drinking water service line material. 

By taking part in this important program, you are helping to provide critical information that is needed to determine your water service line material. We respectfully ask that you please take the time to complete this form and to answer the questions to the best of your ability.

Thank you!
