A catchment includes the entire roof surface within the catchment, the roof gutters, the roof down pipes, the roof drains and any rainwater retention and storage tanks (AusAID 2007).<br /> <br /> ==Explanation==<br /> Roof catchments include the entire roof surface plus all the components use to capture and<br /> store the rain water. The roof materials must be compatible for contact with drinking<br /> water. Quality water harvested from a roof catchment can be improved in storage from a<br /> natural distillation process. Risk to water quality can be from airborne particles and from<br /> man-made air pollution.<br /> <br /> A roof catchment will collect approximately 1 litre of water for every square meter of roof<br /> surface for every millimetre of rainfall (World Plumbing Council Working Group 2008).<br /> <br /> Main points to consider when harvesting a quality and usable water from a roof catchment:<br /> * Ensure the roof surface is of a suitable material for collecting quality rainwater, i.e. not corroded or likely to contribute contamination to the water on contact<br /> * Ensure the roof gutters are installed to building standards and have fall to outlets to prevent ponding and sludge build up.<br /> * Install gutter mesh to prevent leaves and debris from blocking gutters and mosquito mesh to seal the storage from insects and vermin.<br /> * Fit gutter outlets to underside of gutter to reduce sludge build up.<br /> * Fit rain heads to down pipes to ensure the maximum discharge is delivered to the storage.<br /> * Fit a first flush by pass system to separate debris and sludge before storage.<br /> * Draw water from the aerobic zone in the storage.<br /> * Ensure the roof catchment is maintained and cleaned on a regular basis (WHO 2006, AusAID 2007).<br /> <br /> ==Example==<br /> <br /> ==References==<br /> * AusAID (2007) [http://www.developmentgateway.com.au/jahia/Jahia/cache/offonce/pid/ Roof catchments and tanks for rainwater harvesting]<br /> * WHO (2006) [http://www.who.int/water_sanitation_health/publications/plumbinghealthasp/en/index.html Health Aspects of Plumbing]<br /> <br /> ==Links==<br /> * [http://apps.who.int/thelexicon/ WHO — The Health and Environment Lexicon]<br /> * [http://www.developmentgateway.com.au/ Australian Development Gateway]<br /> <br /> [[Category:EN]]</div>
