Montgomery County Works With EPA To Upgrade Infrastructure
Water & Wastes Digest
May 2003
More and more communities face the dual problem of aging infrastructure and overdevelopment due to population growth. Under the Federal Clean Water Act (CWA), EPA is keeping a vigilant eye on the problem. When a community does not meet CWA regulations for sewage overflow, EPA works with that community through long-term loans and expertise to develop a solution. Such is the case in Montgomery County, Ohio.
