We demonstrated the Sewer in a Suitcase, CUP's working model of New York City's sewer system, at two events over the weekend of October 1. The Sewer in a Suitcase made its first stop on Saturday at the New York Green Block Party, an all-day street fair in Williamsburg. Then it moved on to Sneak Peak at Freshkills Park on Sunday, with demonstrations of the Sewer in a Suitcase every half hour.
