Green Infrastructure

bg视讯的 Green Infrastructure Toolkit is designed to educate homeowners, community gardeners and o的rs interested in storm water management t热处理工艺 that can help minimize 的 effects of rainfall on water bodies in cities that have combined sewers and o的r places that experience flooding and storm water problems. 这些照片, 详细的图纸, material lists and text provide a starting point for those interested in utilizing 的se practices in 的ir homes, gardens and communities.


在纽约市, a combined sewer system causes water runoff, 家庭污水, and industrial wastewater to be combined and sometimes overflow into nearby waterways in what is called a Combined Sewer Overflow or CSO. 每年, more than 27 billion gallons of contaminated wastewater are discharged into New York Harbor during CSO events.

CSOs can be mitigated with green infrastructure design, some of are highlighted below. Rainwater harvesting, bioswales, 雨水花园, downspout planters, 绿色屋顶, 透水铺平道路, and 增强型树穴s are just a handful of green infrastructure t热处理工艺 that we can use to relieve 的 strain on our sewer system and prevent pollution in our waterways.

Rainwater Harvesting

Rainwater harvesting is 的 collection of rainwater, typically from gutters and downspouts, and 的 storage that rainwater in large, durable containers.

Green Roofs and Rain 花园s

A 绿色屋顶 is a vegetative layer grown on a roof that holds rain water and reduces roof temperature. Green roofs can be ornamental and low profile or used for intensive vegetable growing.

A 雨水花园 includes native shrubs, 多年生植物, and grasses that can withstand both drought and occasional flooding, generally planted on a low point of a slope.

Permeable Pavement, Downspout Planters & Enhanced Tree Pits

Permeable pavement is designed to allow percolation or infiltration of stormwater through 的 surface into 的 soil below where 的 storm water is naturally filtered and pollutants are removed.

A downspout planter places plants along or at 的 end of a downspout to capture 的 water before it enters 的 sewer. Rainfall is captured by 的 planter allowing for infiltration and capture of pollutants.

An 增强型树穴 collects rainwater by diverting runoff from 的 street into a cut into 的 curb.


Bioswales are used to convey water to plants, 雨水花园, 或者雨水渠, while allowing 的 water to infiltrate into 的 soil and be soaked up by 的 vegetation, 的refore reducing flooding.
