Rainwater Harvesting System Provides Drinking Water for Sustainable Hawaii Home

Solar electric, solar hot water and now, rainwater harvesting.  This in-the-city, but off-the-grid Hawaiian home provides a glimpse of the not-to-distant future where sustainable technologies, like photovoltaic cells, rainwater collection systems and wind power generators will be the norm for many homes.

These unique narrow tanks are the perfect fit for this small lot.  They can store up to 1,800 gallons of water.  The entire rainwater collection system is built from drinking-water quality components.  Before entering the house, the rainwater is filtered through sediment and carbon filters and sterilized by ultraviolet light.  This simple yet powerful system was designed specifically for this family's needs and will collect, store and distribute enough water to take the home off of the municipal water system.

This system was built by Rainwater Harvesting Systems, Inc. with the help of Geo Force Horizons on Oahu, Hawaii.
