Wastewater officials reopened Kalapaki beach on Kauai Saturday with approval from the Department of Health.

State and county representatives have been monitoring the water quality at the beach since a power outage caused a sewage spill at the Lihue Wastewater Treatment Plant on May 16. The outage appears to have occurred on an internal circuit. 

Roughly 400,000 to 500,000 gallons of treated sewage flowed from the plant into a storm drain that leads into the bay, adjacent to Nawiliwili Harbor.

A partial reopening of the beach was approved Tuesday, but beach closure signs remained along the beach fronting the Anchor Cove Shopping Center and Kalapaki Stream. As of Saturday afternoon, all beach closure signs have been removed.
