Know before you go

Planning a trip to the river? Be aware of potentially unsafe water conditions. Our Wet Weather Overflow Notification program informs the public of current or predicted weather that may lead to sewer overflows. 

Receive email notifications

We send email notifications when rainfall of 0.25 inches or more is predicted or recorded in SD1’s service area, including Boone, Campbell and Kenton counties. We also send notifications if the Ohio River exceeds 38 feet. All advisories will remain in effect for 72 hours after rainfall or 72 hours after river levels drop below 38 feet.

Polluted waters can cause serious health issues. Protect yourself and your family by
avoiding contact with water near and around sewer overflows. This includes activities such as boating, wading, fishing and swimming
Look for CSO signage

SD1 has identified and posted signs in “CSO Areas” - areas where combined sewer outfalls are near and overflows are likely. 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.

What is a sewer overflow?

Heavy rains or snow melts can overwhelm Northern Kentucky’s aging pipes and lead to messy sewer overflows. Each year, more than 1.6 billion gallons of water escape the local sewer systems, creating dirty streams and rivers and unsafe water conditions. SD1 is aggressively working to eliminate sewer overflows and advises residents when to avoid contact with affected water.
