News & Updates
Oahu’s municipal drinking water is provided by groundwater sources, which are dependent on recharge from rainfall. Groundwater sources are less susceptible to drought and climate variability. The Board of Water Supply (BWS) continuously monitors rainfall and groundwater levels to ensure the island's drinking water supply is preserved.
If we each save a little, together we save a lot.
While brushing your teeth, fill a cup of water to rinse your mouth and turn off the tap.
The BWS maintains wells across the island to track the health of the aquifers from the effects of varying rainfall and pumping trends. During hot summer months, when rainfall is low and water demand is high, water levels decrease. If water levels drop too low, the source could be harmed, with long-term detrimental impacts. Monitoring low groundwater levels allows the BWS to adjust pumping operations and inform the public that summer water conservation is necessary.
We remind ALL Oahu water customers to please use water efficiently and to not waste it. If we each save a little water, together we will save a lot and ensure water supplies are sustainable for generations to come.
