Maui County is asking customers across Maui island to conserve water as it works to recover from recent heavy rainfall, high winds and flooding that have impacted water facilities.

Numerous power outages, downed power lines, trees and main line breaks have continued to hamper recovery efforts, while severe flooding has caused debris to block intakes to multiple water treatment facilities, reducing normal flow, the county said Tuesday afternoon.

The Department of Water Supply issued the water conservation request for 48 hours, or until Thursday, which is about how long it’s estimated it will take to safely assess and repair damages, bring the water treatment facilities back online and replenish the diminished water storage levels.

Conservation measures include refraining from washing cars and washing down sidewalks and driveways, as well as irrigating lawns, among other measures.

The department had also issued a water conservation request for Kaunakakai on Monday after power outages caused the loss of the Kualapuu well that serves the area.

County employees in other departments are also working to restore regular operations as the damaging Kona low weather system moves further away from Maui County.

The Central Maui Landfill reopened at 6 a.m. Tuesday after flooding, high winds and debris on Pulehu Road forced the facility to close on Monday. The landfill’s regular hours are 6 a.m. to 3 p.m. Monday through Saturday. It’s closed on Sunday.

Weather-related disruptions and staff shortages also postponed trash collections in portions of West Maui and areas of Wailuku and Kahului on Tuesday, forcing some residents to bring their trash out for curbside collection today instead.

While the previously closed Waiehu Municipal Golf Course was open and operating normally on Tuesday, four county parks and facilities were closed for maintenance until further notice due to flooding, muddy conditions and/or downed trees: New Kula Park and Playground at the intersection of Kula Highway and Calasa Road, Baldwin Beach Park, Kenolio Dog Park and Kalepolepo Beach parking lot.

Haleakala National Park’s Summit District also remained closed on Tuesday after the storm as wind speeds remained high and unsafe for vehicles on the road, park officials said.

All reservations for Hosmer Grove Campground, wilderness cabins and wilderness tent camping for Tuesday were canceled.

Park staff were working to clear the roadways of debris, assess trails and restore power to park facilities.

In the park’s Kipahulu District, the Pipiwai Trail, Kuloa Point Trail and Kipahulu Visitor Center remain closed. The district and the campground are open, however, access to the park on Hana and Piilani highways may be limited, park officials said.

The park will reopen once conditions improve.

A cold front over the weekend brought thunderstorms, heavy rain and strong winds that knocked out power for thousands of customers, toppled trees and forced the closure of some roads and facilities due to flooding and debris.

On Tuesday, Sandwich Isles Communications issued an apology for service interruption on Maui, Molokai, Lanai and Hawaii island for the last three days.

“Sandwich Isles is diligently working on restoring services as soon as possible,” the company said in a statement. “Hawaiian Telcom now owns and operates the Paniolo Interisland cable, which carries our service, and is having difficulties that are affecting our ability to deliver service to you. Sandwich Isles’ engineers are working closely with Hawaiian Telcom to fix this service interruption as soon as possible.”

The strong winds also prevented aircraft from landing, particularly on Maui, according to Hawaiian Airlines, which was operating extra flights with larger aircraft to get people off the island, spokesperson Alex Da Silva said.

“Guests traveling today and tomorrow should anticipate potential delays and check the status of their flights before coming to the airport,” Da Silva said Tuesday afternoon. “We apologize for the impact this weather event has had on our guests and are working hard to get them on their way.”

On Tuesday, Hawaiian Airlines canceled 37 flights across its network, Da Silva said. The airline also issued a travel waiver for Neighbor Island and continental U.S. flights, allowing passengers with flight dates between Dec. 20-25 to reschedule at no cost or cancel their flights and use the credit towards a new ticket.
