Rain capture is one of the least-expensive, and cost-effective modifications that can be made to a commercial building. The rain downpipes are simply diverted to inexpensive plastic rainbarrels. This rain water can be coupled with inexpensive gravity-fed drip irrigation tubes to water flower beds and shrubs and beneficial landscaping. Coupled with drip irrigation, Federal water costs can be reduced by up to 90% in certain areas of the country.
