Some of the benefits of [[Rainwater harvesting]] include:

*The ability to reduce the quantity of pollutants and [[Runoff volume control targets|runoff]] being discharged to municipal storm sewers and receiving waters (i.e., rivers, lakes and [[wetlands]]);

*Underground and indoor cisterns can be used year-round and located below parking lots, roads, plazas, parkland, landscaped areas or within buildings themselves.

*'''[[Rain Barrels]] Rain barrels are an above ground form of rainwater harvesting, typically used in residential settings. The precipitation flows from the roof, to the guttering and down the downspout before being diverted to the rain barrel for storage.

*'''[[Downspout disconnection]]''' Downspout disconnections are common in many older urban centers. They require that residents retroactively disconnect their downspouts from the municipal sewer system. This is due to older sewer systems being undersized for the combined flow of sanitary waste and stormwater.

*'''[[Blue roofs]]''' are systems that temporarily capture rainwater using the roof as storage and allow it to evaporate and/or to be used for non-potable requirements (i.e. irrigation, toilet flushing, truck washing) and ultimately offset potable water demands.
