Water System Information and Reports:


The City and its Department of Public Works (DPW) Sewer Division are working to improve the City's wastewater systemto protect theenvironment and meet EPA's wastewater mandates.

The City is currently under a legal order (Consent Decree) from the EPA to upgrade the Peirce Island WWTF to secondary treatment. The upgrade project will be the single largest capital expense for the sewer system to date.

The City was recently notified by EPA that the Peirce Island secondary treatment permit would be made more stringent by requiring nitrogen removal to 8 milligrams per liter (mg/L).

Unrelated to the order, the City anticipates the draft permit for the Pease WWTF will also be more stringent and will result in another significant WWTF upgrade. For more information please visit http://www.portsmouthwastewater.com/
