Upgrades on schedule at city sanitary plants
Work going on since 2010 that cost $120 million to upgrade a project on the city’s central and west wastewater treatment plants remains on schedule.
All of the milestones have been met and are waiting substantial completion, according to the engineer John Amend, of Arcadis, who briefed the Williamsport Municipal Water and Sanitary Authority Wednesday.
The upgrades are to comply with federal and state environmental requirements to reduce nutrient removal heading into the Chesapeake Bay and the wet weather overflow coming from the authority customers in the collection system.
A building known as the operations center at the central plant that contains employee offices and two laboratories is near completion, he said.
The construction updates at the filter building, which filters wastewater, also remain on track, with performance testing to be done April, May and June.
Work at the Basin Street site should be done in three to four weeks, he said. Workers are down beneath the site in a hole where collection lines take wastewater either to the treatment plant or to the West Branch of the Susquehanna River.
