A power outage early Saturday caused a waste-water spill of about 1,250 gallons at the Waiehu Pump Station in Wailuku, Maui County officials said Tuesday

The spill was reported at 8:40 a.m. and was stopped by 9:20 a.m., the Department of Environmental Management said in a news release.

It was caused by equipment malfunction when power was lost due to strong winds, the release said. The waste water flowed from a manhole fronting the Waiehu Pump Station on Akake Street, and flowed along the roadway into a storm drain.

The spill did not reach the ocean because the storm drain was completely blocked with sand, according to the release. The spill site was disinfected and the state Department of Health was notified.
