The Metro Nashville stormwater program, which covers drainage questions, runoff rules and flood information.
Metro Water Services includes a stormwater program that covers drainage, runoff and flood information for Nashville and Davidson County. When roof and yard water leave a property, they enter a larger system of ditches, pipes and creeks, and local rules affect where water may go. A French drain outlet, a sump pump discharge line or a large paved area can raise questions about those rules, and the program is the right place to ask.
We are a private waterproofing company and are not part of Metro Water Services. We plan drainage outlets with local rules in mind and encourage you to contact the program with questions about discharge, runoff and flood information for your property. Officials decide what is allowed, and we are glad to explain what we are proposing so you can ask good questions.
