Thoughts on Catchment Water Systems in Hawaii
Catchment water systems are a vital part of life on the Big Island of Hawaii, particularly in areas that do not have access to county water. These systems allow residents to collect, filter, and store rainwater for use in their homes, providing a reliable source of clean water despite the lack of a municipal supply.
The basic components of a catchment water system include a catchment area, such as a roof or other surface, to collect rainwater. This water is then directed through gutters and downspouts into a catchment tank. This tank is typically made of metal or plastic and is designed to hold a large volume of water.
After the water is collected in the tank, it is then pumped through a series of filters to remove debris and impurities. These filters may include a first-flush diverter, which diverts the initial flow of water to remove any debris or pollutants that may have accumulated on the roof or catchment area. The water is then passed through a series of screens or other filters to remove sediment, leaves, and other debris.
Finally, the water is passed through a disinfection system, such as ultraviolet light or chlorine, to remove any remaining bacteria or other pathogens. The clean water is then stored in a separate tank or cistern for use in the home.
One area on the Big Island that relies heavily on catchment water systems is Hawaiian Ocean View Estates. This community is located in a remote area of the island and does not have access to county water. As a result, residents must rely on catchment systems to provide clean, reliable water for their homes.
Overall, catchment water systems are a crucial part of life on the Big Island, providing a reliable source of clean water for residents in areas without access to county water. The systems themselves are relatively simple, consisting of a catchment area, filters, and a disinfection system. These systems allow residents to collect and store rainwater for use in their homes, ensuring that they have a steady supply of clean water despite the lack of a municipal supply.
