September 22-25, 2019: NEWWA Annual Conference

NEWWARepresentatives of Weston & Sampson will present during the course of this year's NEWWA Annual Conference, taking place September 22-25 in Rockport, ME.

Tuesday, September 24, 2:00 PM — “Capital Improvement Planning with an Asset Management Mindset” by REBECCA GONSALVES-LAMONTAGNE, Engineer II, Weston & Sampson, Reading, MA; and STEPHEN KING, P.E., Town Engineer, Town of Danvers, MA

Using an asset management approach alongside Sedaru’s CIP software, the town of Danvers strategically created a 20-year capital improvement program (CIP) for their water distribution system. In order to prioritize and track projects, the Town created a horizontal asset inventory incorporating information from their water system GIS and hydraulic model. Improvements were prioritized based on asset condition, criticality, and remaining useful life. This presentation provides an overview of designing a CIP with an asset management mindset and the lessons learned.

Wednesday, September 25, 7:30 AM — “PFAS Treatment Method Optimization for a Large Public Water Utility” by MARGARET McCARTHY, P.E., Team Leader, Weston & Sampson, Reading, MA; BRIAN GOETZ, Deputy Director of Public Works, and AL PRATT, Water Supply Operations Manager, City of Portsmouth Public Works, Portsmouth, NH.

PFAS have been identified in public drinking water supply wells at a number of locations in New England above United States EPA's health advisory of 70 parts per trillion (ppt). Treatment to remove PFAS from water supply wells must be carefully designed to assure removal is achieved, accounting for varying water chemistry. This presentation will discuss pilot testing completed at the former location of the Pease Air Force Base in Portsmouth, NH, and selection of system for full scale design.
