Wet Weather Overflow Notification Program

Know Before You Go

Planning a trip to the river? Be aware of potentially unsafe water conditions due to sewer overflows. Protect yourself and your family by knowing when and where to avoid water activities, including boating, wading, fishing and swimming.

Receive Notifications

Sign up for notifications! We will only alert you when:

  • Rainfall of 0.25 inches or more is recorded in SD1’s service area, including Boone, Campbell and Kenton counties
  • The Ohio River exceeds 38 feet

These weather conditions indicate that sewer overflows may occur, polluting waterways. All advisories will remain in effect for 72 hours after rainfall or 72 hours after river levels drop below 38 feet.

Sewer Overflow

Heavy rains or snow melts can overwhelm Northern Kentucky’s aging pipes and lead to messy sewer overflows. Each year, more than 1.4 billion gallons of water escape the local sewer systems, creating dirty streams and unsafe water conditions. Clean H2O40 is SD1’s commitment to reduce and eliminate sewer overflows.

Be Aware of Potential Sewer Overflow Areas

SD1 posts signage in areas where combined sewer overflows (CSOs) may occur. If you see these signs, avoid nearby water during and after rainfall for at least 72 hours. If you notice an overflow or unusual activity, report the issue by calling 859-578-7450, Option 1.
