2023 MWUA Tradeshow & Conference
Join our staff at the Maine Water Utilities Association’s (MWUA) Annual Tradeshow & Conference from February 1-2. As part of the MWUA Program Committee, Project Manager Amanda Keyes is moderating several of the conference’s sessions. Vice President Dan Bisson, PE, and Director of Business Development Adam Yanulis will attend the tradeshow (booth #35).
Below are the speaking engagements our engineers are leading.
WEDNESDAY, FEBRUARY 1
Session 15: Plant SCADA Automation – Implementing the First Fully Automated Water Treatment Plant in Massachusetts
Room: Cumberland
Time: 2:45 PM – 3:45 PM
Track: Treatment & Management
Moderators
Primary: Amanda Keyes, Tighe & Bond
Course Instructor: Stephen Rafferty, Tighe & Bond
Course Description: Since 1898 Falmouth Massachusetts’ relied upon unfiltered water from Long Pond as their primary source of drinking water. In 2014 they committed to piloting, designing, and constructing a treatment plant that would be a model of treatment and operation. One of the primary challenges faced by the Town and the design team was the extreme seasonal nature of demand. Peak summer days typically require five times more water into the system than typical winter days. To balance the need for water and to properly staff the plant a decision was made to invest in full automation. The goal was for the plant to only need to be staffed for a single 8 hour shift daily while still being able to run 24/7 for up to five months of the year. To achieve this the SCADA system needed to be configured as a virtual network, with complete redundancy at every level of the system. The project was a success with the plant becoming the first fully automated plant in Massachusetts. It has had 6 years of uninterrupted operation.
THURSDAY, FEBRUARY 2
Session 25: Using Water Quality Models to Identify and Address Low Chlorine Residual in Distribution Systems
Room: Kennebec
Time: 9:15 AM – 10:15 AM
Track: Distribution & Storage
Moderators
Primary: Amanda Keyes, Tighe & Bond
Course Instructor: Heather Doolittle, Tighe & Bond
Course Description: Maintaining disinfection residuals in drinking water systems is critical. This session summarizes water quality studies to identify areas of low chlorine residual in multiple water distribution systems. Hydraulic models were updated for water quality modeling capability, calibrated using field sampling, and applied to address gaps in monitoring programs and improvement alternatives. Covered topics include a general background in chlorine chemistry, applying hydraulic models for water quality evaluations, and several case studies.
