School of the Future Stormwater Management Techniques


The School of the Future demonstrates the Philadelphia School District’s commitment to technology and sustainable development. Located within 7 acres of Fairmount Park adjacent to wetlands, the Philadelphia Zoo, and residential neighborhoods, the school building was built in 2005-2006 as a collaboration between Microsoft Corporation and the Philadelphia School District, and meets the standards for LEED Gold Certification. These standards require high performance in the following areas: sustainable sites; water efficiency; energy and atmosphere conservation; materials and resources; indoor environmental quality; and innovative design processes.

Stormwater best management practices (BMPs) incorporated on the campus include an 11,600 square foot green roof, a catchment system to recycle rain water, and pervious pavers. These BMPs will reduce the volume of stormwater leaving the site, and the porous pavers will allow parking area runoff to infiltrate into the ground.

Rainwater catchment system: This system collects rainwater from various roofs, and gravity feeds it into a 30,000-gallon underground tank. This rainwater is then pumped back up to the school to be used for flushing toilets and urinals. This combined with other water efficient design is predicted to reduce water use by 60% as compared to a standard building.
