The Hawaii County Department of Water Supply said Tuesday the tap water for its Hilo customers remains safe to drink after the isolated discovery of turbid or discolored water.
DWS suspects the use of fire hydrants on Oneawa Place, Makalani Place and Ka Manelo Street caused the discolored water reported on Monday.
Usage of fire hydrants can cause drinking water in pipes to become turbid and discolored.
There is no indication the water system was exposed to contamination, according to DWS. As a precautionary measure, DWS collected water samples for laboratory analysis, and initial observations confirm that the water is safe for consumption.
In an abundance of caution, DWS recommends area water customers flush their taps, should they experience discolored water, and to call DWS at (808) 961-8790 to report the turbidity.
If customers have water quality related questions, please call the Department’s Water Quality Branch at (808) 961-8670.
