Water Systems 

Here on Maui and throughout the Hawaiian Islands there are basically three ways of getting water supply for your home.

Public Water System

The most common method of obtaining water in the developed areas of the island is from the Department of Water Supply.  This water, mostly collected from surface water such as streams and from ground sources such as wells and aquifers, is tested, treated and then delivered to the home via a series of underground pipes. 
These systems will have a meter and a shutoff valve, typically installed in front of the home by the street.  Water quality testing and all underground piping is not part of a home inspection.  

For more information regarding the Department of Water Supply go to http://www.mauiwater.org.


Private Well Water System
 

Another method of obtaining water for your home is a private well water system.  These systems are more common in the rural areas and can either be privately owned or owned by a neighborhood association. 

Well water has advantages and disadvantages, with the main advantage being that you are completely independent of the county system and have no monthly bill for water.  The disadvantage is that you are solely responsible for the maintenance and testing of the water system which can be expensive. 

Water quality testing and all underground piping and components of a private well system are not part of a home inspection and I always recommend that water quality be tested on a regular basis.

Rainwater Catchment System


A third method of obtaining water is a Rainwater Catchment System.  This method is common in the outlying areas of the island where rain is a common, almost daily event.

These systems consist of a large catchment surface (usually your roof), gutters, storage tanks, pumps and filters.  These systems collect the rainwater, divert it to the holding  tanks via the gutters where it is stored and typically treated, then pumped to the home where it would be filtered and used.  The rainwater catchment system is unreliable and there are many health hazards associated with improperly maintained systems. 

Water quality testing and all underground piping and components of a rain water cathment system are not part of a home inspection and I always recommend that water quality be tested on a regular basis.
