December 4, 2021

In order to update its existing knowledge of the sewer line in the neighborhoods around Ocean Road and Lafayette Road, the City of Portsmouth Department of Public Works will conduct a flow isolation and infiltration assessment, starting at midnight on Monday, December 6, 2021. The work is scheduled to take place between midnight and 6 am, through December 10, 2021, weather permitting.

The work involves lifting sewer manhole covers to assess the pipes between two manhole and will progress through the neighborhoods, one street at a time. The work area will be identified by large vehicles with flashing lights, in the road.

  • Suzanne Drive
  • Simonds Road
  • Wallis Road
  • Ocean Road
  • Winchester Street
