2021 WEF Project Excellence Award, Peirce Island WWTF Upgrade

Portsmouth (NH) Peirce Island Wastewater Treatment Facility Upgrade
Honorees: City of Portsmouth (NH), AECOM (consultant), and Methuen Construction (contractor).
The Peirce Island WWTF Upgrade sustainably upgraded an operating water resource recovery facility on an island with limited access and extensive archaeological and recreational resources located in historic downtown Portsmouth, NH. The team delivered a successful project on a court ordered schedule with increased capacity, secondary treatment, and total nitrogen removal without expanding the site while overcoming public opposition.
