UDF Program Implementation & Update

UDF Program Implementation and Update for BWSC

Weston & Sampson implemented a system-wide unidirectional flushing (UDF) program for the Boston Water and Sewer Commission from 2011 through late 2014. The program included flushing approximately 800 miles of water mains using the Commission’s existing UDF sequences. The UDF program implementation was conducted at night with an annual goal of 220 miles of flushed water mains.

The UDF program implementation tasks included:

Evaluating the existing UDF program and sequences
Developing field protocols for an efficient and effective flushing program
Procuring vehicles, state-of-the-art equipment, and tools for conducting the flushing
Developing a form and methods for field data collection
Implementing the data collection using an iPad tablet device
Creating project website (www.idatacollect.com) for real-time data reporting
Identifying pilot area limits and conducting pilot flushing program
Reviewing pilot flushing program results and finalizing field protocols and equipment
Conducting the flushing program to achieve 220 miles of flushed water mains each of the four years
Creating an electronic data reporting format to import data into the Commission’s Cass Works software
Performing periodic safety audits to ensure implementation of field protocols
Monitoring the flushing program implementation and providing periodic progress reports to the Commission
