VISITING AND LEARNING ABOUT THE PLANT
Tours are offered on Tuesdays and Fridays only. Prior reservations are required for all tours of MWRA facilities. Please see important security information below.
We welcome visits from professional groups, civic clubs, and especially interested MWRA customers. Reservations and I.D. are required.
The MWRA generally offers tours of Deer Island each month from April through November beginning at 9:30 a.m. when there are people signed up. Tours are offered on Tuesdays and Fridays only, with reservations at least two weeks in advance. School groups and larger groups should make arrangements at least a month in advance. Deer Island is a large, industrial complex, so children 12 and under are not allowed due to safety concerns. Upon reserving a tour, visitors will receive a security form.
Important Security Information
Domestic visitors are required to complete and submit their form to MWRA Security 7 days in advance of their tours. International guests are required to submit their completed forms 14 days in advance, along with a copy of their passport.
Our tours take visitors to the heart of a working treatment plant filled with heavy machinery. For the safety of our visitors and our staff, we must restrict our tours to students in Grade 7 or above. Those interested in visting the plant with children in grades 6 or below are encouraged to try our Deer Island Scavenger Hunt.
No Pets Policy
NO PETS are allowed on facility tours. Only service animals trained to perform a specific task for the benefit of a person with a disability are permitted.
To reserve a group or individual tour, please contact our Deer Island Tour office by phone: (617) 660-7607, or email: Nadia.Caines@mwra.com.
