Sourcebook Harvested RainwaterIn the Austin region, there are a small but increasing number of rainwater harvesting systems. A smallsegment of the population desires rainwater catchment systems for indoor water use. A larger portion ofthe population feels there is an advantage of using captured rainwater for irrigation. Rainwater harvestingpresentations draw large crowds.REGULATORY:At present, there is no Texas regulation for rainwater for indoor or outdoor household use unless thesystem is backed up by publicly supplied waterlines. If a backup system is used, to avoid any crossconnection,an airgap must exist between the public water and rainwater. (An example is a city water linefeeding into a rainwater cistern.) This airgap must exceed two diameters of the city line in width. TheHealth Department will require that the rainwater system does not contribute to mosquito breeding byhaving an uncovered cistern.Guidelines1) Capacity2) Rainwater for IrrigationExample of Irrigation Requirement Estimation3) Subsystem ComponentsCatchmentConveyanceStorageFilteringDistributionRESOURCESPROFESSIONAL ASSISTANCE:Add your company to this list!See "Systems" suppliers belowhttp://www.greenbuilder.com/sourcebook/rainwater.html (5 of 12) [1/13/2005 12:49:01 PM]
