Project Overview

Updated September 18, 2018

Environmental Services is constructing a project to repair over 15,000 feet, or about 3 miles, of public sewers in the St. Johns and Cathedral Park neighborhoods. Many of the sewer pipes are about 80 years old and deteriorating due to age. This project will protect the public and the environment by reducing the possibility of sewage releases to homes, businesses and streets.
