Guidelines on Rainwater Catchment Systems for Hawai`i
Guidelines on Rainwater Catchment Systems for Hawai`i [PDF: 13.6 MB - July 30, 2020] Prepared by College of Tropical Agriculture and Human Resources, University of Hawai`i at Manoa.
An estimated 30,000 to 60,000 people in Hawaii are dependent on rainwater catchment systems for their water needs. Despite the fact that so many people own and use these systems, very little information has been available about their design and maintenance until now. This publication addresses water quality issues from the raindrop to the faucet. It includes chapters on water collection, water storage, water treatment, water testing, and firefighting concerns, and it gives an overview of the typical kinds of catchment equipment used in Hawaii. These guidelines are intended as a practical reference on the major concerns and best management practices for proper maintenance of rainwater catchment and storage systems.
