Cincinnati has a sewage problem, with over 200 hundred combined sewer overflow points and hundreds of miles of streams that flow through sewers overwhelming the waste-water treatment plants. Sewer overflows violate the clean water act and we are required to repair and rebuild our outdated and failing sewer system. Many communities utilize their storm-water fees to incentivize homeowners to install green infrastructure like rain gardens or rain barrels. They also require storm-water management like rain gardens or swales for new construction and collect fees on large impervious surfaces.
