WEST ALLIS WATERWORKS Lead Service Line Inventory
What you need to know
West Allis Waterworks serves about 63,240 people in Wisconsin. The utility draws water from surface sources (lakes, rivers, or reservoirs).
The current status: West Allis Waterworks has not yet inventoried its lead service lines—that is, the pipes that connect the water main under the street to individual homes. This is not unusual; many utilities across the US are still in the early stages of mapping which homes have lead lines.
Lead service lines are a real concern because lead can leach into drinking water, especially if water is corrosive or if pipes are old and worn. However, the presence of a lead service line does not automatically mean your water is unsafe—it depends on water chemistry, treatment, and other factors.
What's happening next
Federal rules require all water systems to complete a lead service line inventory by October 2024. West Allis Waterworks may have submitted an inventory to the state, applied for an extension, or be working toward the deadline. Contact the utility directly for the latest timeline and what they've found so far.
The utility has not yet indicated whether it has received funding under the Bipartisan Infrastructure Law to help with lead line replacement. If funding becomes available, it typically supports removal of confirmed lead service lines.
What you can do now
1. Contact West Allis Waterworks to ask: - Do you have a lead service line inventory yet? When will it be ready? - If you don't know whether your home has a lead line, ask the utility to check their records or describe how to find out.
2. Reduce exposure while you wait: - Let cold water run for 30 seconds before drinking or cooking. - Use cold water for drinking and cooking (hot water leaches more lead). - Have your water tested if you're concerned (contact the Wisconsin Department of Natural Resources for certified labs).
3. Monitor your utility for updates as the inventory is completed.

Frequently asked
Does West Allis have lead pipes?
West Allis Waterworks has not yet published a complete lead service line inventory, so the exact number is unknown. The utility is required to complete one by October 2024. Contact them directly for current findings.
Is my water safe if I have a lead service line?
A lead service line is a potential risk, but not automatic proof your water is contaminated. Water chemistry, treatment, and pipe condition all matter. Have your water tested by a certified lab if you're concerned.
How do I know if my house has a lead service line?
Contact West Allis Waterworks with your address—they may have records. You can also look at your water line in the basement or crawl space; lead is soft, dark gray, and can be scratched with a coin.
Will the utility replace my lead service line?
West Allis has not yet announced a replacement plan. Once the inventory is complete, the utility and state will work on a timeline and funding strategy. Ask the utility when you expect to hear more.
