Deer Island In Photos

They say a picture is worth a thousand words, so for our report on the Deer Island tour, let’s see a few. A tour group from GMWEA. VRWA, and NHWPCA visited the huge, state-of-the-art wastewater plant on October 3 and got a good eyeful. Thanks to Elizabeth Walker and Wayne Graham for the photos!

It’s pretty big.

Deer Island WW Tour Coming Up Oct. 3!

NOTE: This tour is at capacity, and no more registrations are being accepted. Sorry! But return to this site in October for more about the Deer Island WW plant and the tour.

Operators, administrators, engineers, planners, educators – don’t miss the bus!  Join GMWEA, VRWA, and NHWPCA for a tour of the huge, state-of-the-art Deer Island Wastewater Treatment Plant in Winthrop, Massachusetts! This is a rare opportunity to get a close-up view of one of the 20th century’s most challenging and successful environmental improvement projects — and to earn 2 TCHs. 

Deer Island Wastewater Treament Facility, Winthrop, Mass.

Serving 2.3 million people in 43 Boston-area communities, Deer Island is the largest waste water facility in New England and the second or third largest in the US.  Its average influent flow of over 300 mgd and maximum storm-influenced flow of over 1,280 mgd are accommodated while discharging consistently clear effluent through its 24-foot diameter, deep-ocean, gravity-fed  9.5-mile outfall tunnel.  A total of 5,000 miles of sewer pipe serves the facility.

Completed in 2001, this mammoth plant’s design and construction reflect the desire to minimize environmental impacts, of every kind, on Massachusetts Bay.  Its renewable energy systems, for example, provide more than half of the island’s electricity through a combination of methane biodigesters, wind turbines, solar power, and hydro-electric generation.

The tour will be guided by plant process engineering staff.  Adding a deep insider’s knowledge, they will tentatively be accompanied by their former colleague, Charlie Tyler, who retired from the plant in 2017 after over 25 years of involvement in planning, design, construction, start-up, and process operations there.

GMWEA has chartered a bus for Thursday, Oct. 3, to transport attendees to the plant. The bus will depart from the South Burlington Department of Public Works (104 Landfill Road, South Burlington, Vt.) at 6:45 a.m. It will make two additional stops: at the Upper Valley Plaza/JC Penney Plaza (250 N. Plainfield Rd., Unit 202, West Lebanon, N.H.) at 8:15 a.m., and at the New Hampshire Mall (1500 S. Willow St., Manchester, N.H.) at 9:45 a.m. Attendees can be picked up any of the locations.

After the tour, the bus will leave Deer Island at 2:30 p.m. Passengers will be dropped off in Manchester at 4:00 p.m.; in West Lebanon at 5:30 p.m.; and in South Burlington at 7:00 p.m.

The Vermont DEC has confirmed that tour participants will receive 2 TCHs (for the tour, but not the bus ride!). 

The charge for the day’s activities is $65 per person. Attendees need to pack a lunch and dinner — meals are not provided, and stops for food are not planned. Light refreshments and snacks will be available on the bus, or you can bring your own. Alcohol is not permitted.
