WA DOH guidance requires a minimum of 1 verification point for each side (utility-owned and customer-owned) of the service line. Depending on the age and type of water service construction, this may be possible to complete from within the water meter box and excavation will not need to take place.
If this is the case, CPUD personnel will record the service line materials to be added to the inventory. If excavation is needed, CPUD personnel will mark the area around the water meter box in white paint and call 811 for a locate ticket at least 2 business days prior to starting work.
CPUD personnel may leave a door hanger at your residence if your water meter is located in an area where water personnel might want you to have advance notice of the excavation.
