secondary source of water for gardening in residential areas. If larger water storage volumes are desired, larger tanks called cisterns can be used to collect rooftop runoff. Rain barrels can provide a source of chemically untreated 'soft water' for gardens and compost, free of most sediment and dissolved salts. Because residential irrigation can account for up to 40% of domestic water consumption, water conservation measures such as rain barrels can be used to reduce the demand on the municipal water system, especially during the hot summer months.
For residential applications, a typical rain barrel design will include a hole at the top to allow for flow from a roof downspout, a sealed lid, an overflow pipe and a spigot at or near the bottom of the barrel. The spigot can be left partially open to detain water or closed to fill the barrel. The top opening must be fitted with a screen in order to control mosquitoes and other insects. The stored water can then be used for lawn and garden watering. Rain barrels can be connected to provide larger volumes of storage.
Rain barrels should generally NOT be directly connected to your home's potable water or automatic irrigation system. Rain barrels connected directly to a potable water or automatic irrigation system must be equipped with a certified backflow device and must be permitted, inspected and approved by the City Building Inspection Division prior to installation.
