 Welcome to Possibly, where we take on huge problems like the future of our planet and break them down into small questions with unexpected answers. I'm Megan Hall. Recently, we talked about how our hometown of Providence, Rhode Island, built a huge tunnel to help store stormwater so the sewage treatment plant can keep up when it rains. But can we prevent stormwater from going into the sewer system in the first place? Possibly reporters Will Malloy and Juliana Marullo are here to tell us more. Hi, Megan.
