The Hamilton County Storm Water District has been established in response to the federally mandated Phase II storm water program.  The Ohio EPA is issuing a National Pollutant Discharge Elimination System (NPDES) general permit that authorizes operators to discharge storm water from small construction activities and requires the development and implementation of a stormwater management program (SWMP) to reduce the contamination of stormwater runoff, and prohibit illicit discharges.

The Storm Water District represents Hamilton County's commitment to storm water issues.  The District membership consists of 39 of the 49 jurisdictions in Hamilton County including all 12 of the townships.  

We invite you to browse our website to learn more about storm water and the Storm Water District.  New information will continually be added to this website, with the long range goal being a website that can serve as a central repository for all storm water related material.
