The Water Trailer

Fill. Drink. Repeat.

Boston Water and Sewer Commission's Water Trailer

Bostonians take pride in their clean, high-quality tap water that stems from the Quabbin and Wachusett reservoirs, which have been the main water sources for Boston since the early 1900's. In 2017, BWSC won the 8th annual "New England's Best Drinking Water Taste Test" competition at the New England Water Works Association annual conference. In 2014, the Boston Water and Sewer Commission's (BWSC) water was awarded "Best of the Best" nationally at the American Water Works Association's (AWWA) tenth annual tap water taste test.

BWSC wanted to come up with a way to distribute its tap water to Boston residents and visitors attending events and walking through the city. The Water Trailer made its debut in 2014 with six taps for people to fill up their water bottles. BWSC customized the trailer, adding four water bubblers and two doggy bowls so that people and their pets could use the trailer at the same time. BWSC also made the trailer ADA compliant making it more accessible to people with disabilities.

The Water Trailer's mission is to serve BWSC's campaign, "We Are All Connected". The campaign's purpose highlights ways to educate the public on how we can reduce stormwater pollution that ultimately affects local waterways, as well as to promote alternative solutions that would help better the community, environment, and waterways around the city of Boston.

The motto for the Water Trailer is "Fill. Drink. Repeat." BWSC's goal is to motivate residents and visitors to drink and enjoy our water, but also refill their single-use bottles, to ultimately conserve plastic bottle usage in the city. The trailer has been featured at many events that educate the public on how the community can make Boston a cleaner, healthier environment. Having the Water Trailer present at educational events demonstrates to the public that if we protect our waterways, we will help conserve potable water for Boston's future.

Along with these civic events, the water trailer has made additional appearances across the city. These events range from food festivals, concerts on City Hall Plaza, and the 4th of July concert and fireworks on the Esplanade. It has even made appearances during heat emergency days to ensure that everyone had access to water and were able to stay hydrated.

The success of the water trailer has increased substantially over the last three years. In 2014, its first year of operation, the water trailer appeared at about 20 events. This increased to about 70 events in 2015 and to just over 100 events in 2016. These events often are crowded with Bostonians and visitors, bringing awareness to the water trailer and the "We Are All Connected" campaign.
