Massachusetts Water Resources Authority Independent Flow Meter Audit, Greater Boston Area (2011-2015)

EST was selected by The Massachusetts Water Resources Authority (MWRA) to install, program, and calibrate over 160 open channel flowmeters throughout the Greater Boston Area. The MWRA is the largest wastewater authority in New England and treats sewerage from 43 cities and towns in the Greater Boston area. 

EST’s temporary flowmeters were used to measure and record flows to verify and document the accuracy of permanent MWRA flowmeters used to measure sewer flows from municipalities throughout the MWRA service area.  In addition, EST provided reviews of record drawings of monitoring sites, site/manhole mapping, instantaneous flow measurements, and detailed report generation.  All work was performed in accordance with applicable OSHA regulations and Department of Transportation (DOT) traffic safety standards.
