Where the water comes from
Aqua PA Superior Main System's main water source is purchased surface water. It buys treated water from Pottstown Borough Water Auth. The seller treats the water, including corrosion control that keeps lead from dissolving out of pipes, while Aqua PA Superior Main System is responsible for its own service line inventory and replacement program.

Check your own address
These counts cover the whole system. To see whether your line is lead, use the utility's address-level inventory. Utilities had to prepare one by October 16, 2024 and make it publicly accessible; systems serving more than 50,000 people must post it online.

Protect your drinking water now
If your line is lead, galvanized or unknown, filter water for drinking, cooking and baby formula. Use a filter certified to NSF/ANSI 53 for lead. Run cold water for a few minutes after it sits for hours, and never use hot tap water for cooking.
