PORTSMOUTH (AP) — Portsmouth officials say the city's upgrade of the Peirce Island Wastewater Treatment Plant will likely cost around $100 million by the time work is finished on the project.
The Portsmouth Herald reports City Manager John Bohenko acknowledged the increase Thursday at an open meeting hosted by the Greater Portsmouth Chamber of Commerce.
City officials previously estimated the total cost of the project would reach $82 million. Methuen Construction was awarded the $72.8 million contract to upgrade the sewage plant in August.
Bohenko attributed the rising cost to various overruns associated with the project like fixing the Peirce Island Bridge.
City Engineer Terry Desmarais said the project will not cause significant disruptions to traffic and businesses on the island.
The upgrade is expected to be completed in four years.
