Lead Service Line Inventory Submission

Submissions Open from August 1st, 2025 to September 30th, 2025

The map below displays statewide data that has been gathered to-date during the inventory process.

Drinking water is free of lead when it leaves the water treatment plant. However, water can absorb lead if it travels through lead pipes on its way to your faucet. The majority of South Dakota water pipes are free of lead, but we need to find where lead lines still exist so they can be removed.
