Update: Mandatory 10 percent water cutbacks remain in effect for Wailuku-Kahului-Paia water system

The County of Maui Department of Water Supply is continuing to require customers on its Wailuku-Kahului-Paia system to reduce water usage by at least 10 percent as part of a Stage 1 water shortage declared late last month.

The Stage 1 declaration came after a Wailuku water pump failure over the April 25-26 weekend. The 10 percent cutback in water usage is mandatory until further notice.

Under Stage 1 restrictions, consumers should postpone the washing of vehicles, irrigation of landscape or unnecessary water use at this time.

“Last week, we returned one well back on line, with approximately 500,000 to 700,000 gallons per day. Crews have been working overtime to get a second well on line to provide an additional 2 mgd as soon as possible,” Department of Water Supply Director Jeffrey Pearson said. “However, at this time, we still haven’t returned enough available water source to lift the restrictions. When we have another well back on line, we can reassess the water cutbacks.”

At the end of last month, four water pumps were out of service in the Central Maui-Paia region. The department’s capacity from those sources was down by as much as 6 million gallons per day. Water demand in the system area averages about 24 mgd. The department increased production at other wells and at the Iao Water Treatment Plant to offset the loss of water from the four wells.

“The department appreciates our customers’ support during these emergency conditions,” Pearson said.

Consumers with water problems may call the 24-hour service line at 270-7633.
