New York City wants to catch and store rainwater temporarily in new roof systems to stop heavy storms sending sewage spilling into city waterways.

The catchment systems would consist of "blue" roofs that have a series of drainage pools and "green" or grass- or ivy-covered roofs, under a plan unveiled by Mayor Michael Bloomberg.

During heavy storms, the city's 14 wastewater treatment plants turn into major polluters. That is because much of the city's water system was built 150 years ago when it was common practice to let rainwater drain into the sewage system.

New York City could capture an inch of rain in 10 percent of the older neighborhoods by using a variety of green methods, such as rain barrels and porous parking lots. Sidewalks could be planted with strips of greenery which also could absorb rainwater and release it slowly.
