Abstract
The Combined Sewer Systems (CSOs) of New York City, NY are polluting local waterways including the East River, Hudson River, and the Long Island Sound with billions of gallons of sewage annually. Climate change, aging infrastructure and population growth worsen this pollution problem without a plan to remedy the problem. Large-scale and small-scale construction technology exists that eliminate most CSO pollution. Small scale solutions are constructed by retrofitting roofs and hardscapes on individual properties. This study will create physical models of small- scale hardscape and roof retrofits designed to remove or hold rainwater on the property rather than it immediately entering the combined sewer system. The models will be tested with a system that will simulate heavy rainfalls equivalent to a 5-year storm. Additionally, price estimates will be generated to produce generalized costs for the retrofits and costs per gallon to remove or hold the stormwater. If proven to be functional, logistical, and cost effective; legislation could be considered to require all properties to control stormwater locally then release it into the sewer system when commanded by local water authorities. Proposed funding includes an additional charge on water bills, grants, and private public partnerships.
