Since county and private water service is not available in many parts of the Big Island of Hawaii it would be a good idea for you to familiarize yourself with alternative water systems. The most common one you will see is the catchment system.
Though the system described below is one that is used most everywhere, there are many variations to the individual components depending on the needs of the user and the area in which they reside.
We recommend that you familiarize yourself with the concept only and then investigate the particular components included with the properties you are interested in to see if they meet your needs. If you are planning to build a new home you can expect to spend approximately $2000.00 on a system that would be adequate for most households.
