Project Overview

Updated January 8, 2018

Environmental Services is designing 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.

Environmental Services was awarded a noise variance permit for night work at the locations proposed on the map above.

Project Vicinity

Environmental Services is also designing a large sewer repair project in the Portsmouth and University Park neighborhoods. The city will coordinate construction and outreach for both projects. The project vicinity map shows the boundaries for both the Portsmouth-University Park and the St. Johns-Cathedral Park projects.

Project Area

The St. Johns-Cathedral Park project requires sewer repairs in several active business areas in the neighborhood, including N Lombard and N Ivanhoe streets. The city will be reaching out to neighbors and businesses to better understand business operations and access needs during construction.


Construction is anticipated to begin in summer 2018 and take about a year and a half to complete.
