What to do next
- Ask your local utility for its service-line inventory or map first; Washington's state page says customers should contact their own utility about service-line information.
- If your utility identifies your line as lead, GRR, or unknown, ask whether it has state-funded DWSRF replacement financing or a local repair-loan program.
- In Spokane, check the utility rehabilitation program early if your pipe is leaking, misaligned, or classified as GRR, because eligibility is income-based.
