Robert T. Mackie, PE, BCEE

Bob, Chief Operating Officer of BETA and a Senior Vice President of our water and wastewater department, is a recognized national expert in water and wastewater systems by the American Academy of Environmental Engineers and has been given the title of Board Certified Environmental Engineer (BCEE). Bob is a registered professional engineer in Massachusetts, Rhode Island, Connecticut, Maine, and Vermont. He has experience throughout New England with the entire process of drinking water, wastewater, and stormwater projects, including planning, rehabilitation, design, bidding, and construction.

Bob’s project experience includes assisting Plainville, Massachusetts in designing a new groundwater source and replacing and upgrading the Town’s water treatment facility, including removal of PFAS from their source water. He also assisted the Town with modeling its water system, addressing compliance with Disinfection Byproduct violations, and developing an aggressive infiltration/inflow investigation/rehabilitation program, which led to nearly $1M in rehabilitation in a single season. Additionally, Bob has assisted the following municipalities with their water/wastewater projects:

• Charlton, MA: Developed a new municipal groundwater supply.
• Bellingham, MA: Modeled a water system.
• Billerica, MA: Oversaw design of a 30,000 linear foot sewer extension.
• Everett and Medford, MA: Served as the stormwater on-call consultant.
• Needham, MA: Served as OPM for the design and construction of the $5M Reservoir B sewage pump station.
• Salisbury, MA: Oversaw an elevated 500,000-gallon water storage tank replacement.
• Framingham, MA: Developed a water system-wide master plan including a full computer model.
• Randolph, MA: Directed a $20M water distribution system upgrade.
• North Attleborough, MA: Evaluated flooding from the Ten Mile River.
• Hartford, CT Metropolitan District Commission: Oversaw a $40 million sewer separation project

Bob also oversaw the Route 128 sewer realignment project in Needham, which included preparing a design that eliminated over three miles of sewers within the right of way. This elimination required crossing Route 128 a total of five times using a combination of trenchless technologies such as pipe jacking, directional drilling, and pipe ramming.

Bob, as chair, teaches classes for the New England Water Works Association Distribution and Storage Committee, including a hydraulics class for operators regarding design and operation of a water distribution system. His favorite pastime is swinging the clubs at his home course, White Cliffs Country Club, in Plymouth, Massachusetts.
