Our Water Source

General InformationGreat Miami Buried Valley Aquifer Map

Our regional water resource is the Great Miami Buried Valley Aquifer, which holds more than 1.5 trillion gallons of water. The aquifer stretches across 15 counties, from Hardin to Hamilton, and is constantly replenished by rain, surface water, and manmade recharge ponds, and it is protected by the City of Dayton's Source Water Protection Program.

We do not treat drinking water. We purchase treated drinking water from the City of Dayton and distribute it to our 80,000 customer accounts using more than 1,400 miles of water mains, 12 pump stations, and 14 water storage facilities (e.g., water towers). We also maintain and ensure the operation of more than 12,000 fire hydrants in Montgomery County, Ohio.

Protect Your Drinking Water

You can do your part to ensure our water resources stay healthy and abundant. Here are some tips:

  1. Responsibly Dispose of Household Hazardous Waste. Don't pour chemicals down the drain! You can dispose of household hazardous waste for free at our Solid Waste District.
  2. Never Litter. Litter and other debris get washed into our waterways.
  3. Dispose of Used Engine Oil. Always collect and dispose of used engine oil in a responsible manner to avoid contaminating waterways.
  4. Don't Flush Prescriptions. Don't flush old medicines and prescriptions down the drain. Dispose of them at an approved drop-off location.
  5. Reduce Your Water Usage. Help ensure the long-term abundance and supply of our drinking water by managing your water usage. View some Water Conservation Tips.
  6. See It. Report It. Report water main breaks, sewer backups, or broken fire hydrants immediately using our 24-hour dispatch line at 937-781-2678. You can also Report Water Theft, and Report Illegal Dumping.
