More and more people are coming to realize that harvesting precipitation, primarily from roofs of buildings on their property can provide an adequate household water supply when very reasonable conservation measures are implemented. Expanding experience worldwide has developed technologies and components that result in systems which are relatively low in both capital and maintenance costs.
In May, 2005 , a very successful workshop was held on Hornby Island with guest speakers brought in by Water Stewardship to demonstrate and explain how to install and maintain rainwater harvesting systems for new buildings and for existing structures. Several sites on Hornby were visited to see the practical applications.
An excellent guide to Rainwater Harvesting has been prepared by the Nanaimo Regional District, http://rdn.bc.ca/events/attachments/evID6235evattID1344.pdf
