“Interstate Wastewater has always provided me with the right solution, no matter how tough to hear or implement. They stand by their work, which generally exceeds expectations, and they never run out of creative ways to solve problems. I respect their knowledge and capabilities, and I’m happy to bring them in whenever they can help.”

Interstate Water & Wastewater Specialists, LLC was founded in 1987 by Robert M. “Bob” Chervincky, P.E., a systems designer and a practiced process engineer with construction capabilities. Bob started the company to service the needs of municipal and industrial wastewater treatment plants requiring consulting, repair and turn key installation services for smaller, specialized projects for which traditional consulting was not cost-effective. With the extensive experience of the founder, IWWS offered workable and affordable solutions to public and private facilities both large and small in the New England area. Over the decades, the business expanded to include fabrication and construction projects, in addition to the design and repair services it was originally known for. In 2007, Bob’s son Mark Chervincky, a civil engineer with experience working for wastewater treatment facilities and consultants, joined the company, making Interstate Wastewater a multi-generational family business.
