Green Infrastructure Challenge

In April 2013 DC Water launched the Green Infrastructure Challenge, engaging firms to design innovative green practices that absorb rain water. These practices, known as Green Infrastructure, include installing green roofs (gardens on rooftops), rain gardens, rain barrels, and pervious pavements, removing impervious surfaces, and using other natural means to capture and infiltrate rain water. Capturing the water before it can enter the combined sewer system will aid in alleviating combined sewer overflows in the District.

At the award ceremony on January 9, 2014 DC Water announced the winning submissions for the design phase of the challenge.

DC Water is awarding $1 million for design and construction of these Green Infrastructure projects in the Potomac and Rock Creek drainage areas in the District of Columbia. A subset of the projects above will be constructed in the District.

This Challenge will serve as a model to support DC Water's proposal to conduct a large-scale, multi-million dollar demonstration project in the Potomac and Rock Creek sewersheds to evaluate the feasibility of using green practices, in place of or in conjunction with "gray" engineering solutions, to capture rain water and prevent combined sewer overflows (CSOs).
