Rainwater harvesting is an old traditionpracticed in all parts of the world including Texas.SUPPLIERS:Suitable roof and gutter materials are common products in our region. Specialized products such as roofwashers (pre-filters) are also available in our region. Storage tanks (cisterns) are available regionally andstatewide. System designers and installers are present locally.COST:Rainwater harvesting systems are costly compared to a city hookup. Compared to a well, they are equalor, likely, greater in cost.IMPLEMENTATION ISSUESFINANCING:Appraisers may not properly value a rainwater harvesting system and underwriters may not accept thissystem as the sole source of household water. If the owner provides a backup water source, such as an ondemandsupply contract with a water hauler, lenders would be more favorably inclined to accept suchsystems. It has become more common for new homes with rainwater systems to receive conventionalfinancing.PUBLIC ACCEPTANCE:http://www.greenbuilder.com/sourcebook/rainwater.html (4 of 12) [1/13/2005 12:49:01 PM]
