What to do next

1. Complete the statewide WY Risk It customer survey if your utility asks for service line information or if you received a notice that your line material is unknown.
2. Check your utility’s local FAQ or inventory notice page before paying for replacement work; many Wyoming systems are still in the inventory and planning stage.
3. If your line is confirmed or suspected lead, ask your utility whether it has a current replacement plan, whether state grant funds are available, and whether temporary filters or testing are offered.
