Environmental Program Areas » Drinking Water
In Hawaii, the primary drinking water supply comes from underground aquifers fed by rain-fall. As mandated under Federal and State law, water samples for chemical and biological parameters are taken at the water source and at various points within the distribution system for all drinking water systems serving our installations. If you reside in Army family housing, chlorine and fluoride are added to the water, as required by Army standards, before it is piped into the distribution systems and before it enters your home. Note that if you reside off-post, fluoride is not added to your drinking water as it is not a mandated requirement of the State of Hawaii - Department of Health.


USAG-HI obtains its drinking water through a combination of public systems and privately owned and operated systems.


Sampling results are summarized annually in the Consumer Confidence Report and must be distributed by July 1st each year. Aside from the drinking water contaminants detected the previous year, the CCR also contains a wealth of information about your water system including information about origin of the water, and the source of potential water quality problems.


Army Maintained Water Systems
Other Systems
Aliamanu - (Water comes from the Navy - Army maintains pumps and tanks)
PTA - Privatized system
Fort Shafter
KMC - Privatized system

Drinking water is managed in compliance with the Federal Safe Drinking Water Act, State of Hawaii - Department of Health and Army regulations. USAG-HI drinking water operating permits have been issued, in perpetuity, by the Department of Land and Natural Resources.


  • 40 CFR Subchapter D, Parts 100-135 and 136-149
  • AR 200-1, Chapter 2
  • Department of the Army Pamphlet 200-1, environmental Protection and Enhancement, Chapter 2
  • HAR 11-20 Rules Relating to Potable Water Systems
  • HAR 11-25 Rules Relating to Certification of Public Water System Operators


The Safe Drinking Water Act requires all community water systems to provide an annual Consumer Confidence Report (CCR) to their customers. CCRs are designed to educate the public on the origin of the water, the source of potential problems and the steps used to ensure that the water is safe to drink. USAG-HI is providing this report as a service to the community in conjunction with this requirement.


If you have any questions about the Safe Drinking Water Program, call 656-3103.

All storm water related records can be found in the Environmental Library - Wheeler Army Airfield Building 105.

General water conservation guidance for installation personnel is promoted through public education and outreach events.

Each public water system in Hawaii (except for transient, non-community public water systems) must be under the responsible charge of an operator(s) holding a valid certification equal to or greater than the classification of the water treatment plant (WTP) or distribution system (DS).

WTP operators or DS operators in Hawaii must be certified by the Board of Certification of Public Water System Operators. Chlorination and fluoridation facilities can be operated by either certified WTP operators or DS operators.

Operators of WTP requiring treatment such as filtration, corrosion control and fluoridation must be certified. This certification must be renewed every other year.

WTP Classification: Aliamanu, Fort Shafter, Schofield Barracks, and Tripler Army Medical Center all have a Class 1 water treatment plant classification which represents systems that use slow sand filtration; chemical addition, such as for chlorination, fluoridation, pH control, or corrosion control; granular activated carbon filtration; or packed aeration towers or air stripping towers.

DS Classification: Aliamanu, Fort Shafter, and Tripler Army Medical Center all have a Class 2 distribution classification which represents distribution systems that serve water systems with a population of 1,501 - 15,000 persons.

Schofield Barracks has a class 3 distribution system classification because it serves a larger water system then the other installations. Class 3 represents distribution systems that serve water systems with a population of 15,001 to 50,000 persons .

There are two WTPOs responsible for all Garrison water systems and one DSO responsible for all Garrison distribution systems.
