Our Wastewater Engineering and Construction Division is preparing project sites across Oʻahu ahead of Hurricane Lowell.

Crews are removing storm drain inlet protection to help keep water flowing and reduce the risk of flooding. They are also securing portable toilets and other equipment to prevent them from tipping over during strong winds.

As our crews prepare, residents should take steps now too:

• Clear drains and gutters around your property.
• Secure loose outdoor items.
• Prepare your home and emergency kit.
• Monitor official forecasts and guidance.
• Sign up for HNL Alert at hnlalert.gov.

Stay safe. Stay informed. Be ready to act.

Our Refuse crews are preparing facilities across Oʻahu ahead of Hurricane Lowell.

Crews are clearing stormwater drains to help keep water flowing and moving waste out of facilities to create additional capacity ahead of the storm.

Hurricane Lowell is forecast to pass west of the Hawaiian Islands Monday. While the greatest potential for direct impacts remains focused on the western islands, Oʻahu could experience heavy rain and dangerous surf.

As our crews prepare, residents should take steps now too:

• Secure loose outdoor items.
• Prepare your home and emergency kit.
• Avoid dangerous ocean conditions.
• Check on family, friends and neighbors.
• Sign up for HNL Alert at hnlalert.gov.

Stay safe. Stay informed. Be ready to act.

ENV will conduct smoke testing of the wastewater system in the Enchanted Lake area from September 7 through October 16, 2026, weather permitting.

During testing, crews will release non-toxic smoke into sewer lines to identify leaks and defects. This work helps maintain a safe and efficient wastewater system.

What to expect:
• Testing will take place during normal business hours
• You may see smoke coming from manholes or vents
• The smoke is non-hazardous

Smoke should not enter homes or businesses. However, if it does:
• Open windows for ventilation
• Call (808) 768-7238

Restored & ready for public use! Today we were thrilled to reopen the temporary debris site at Patsy T. Mink Central Oʻahu Regional Park (CORP) after it was utilized to help our North Shore neighbors impacted by March's devastating Kona Low storms.

Environmental Services Director Roger Babcock joined DPR staff, State Senator Danielle Bass, and Councilmember Matt Weyer at the former debris site, located near the corner of Kamehameha Highway and Ka Uka Boulevard, to mark the occasion and thank the community for its patience during the restoration process. To show the grounds were once again safe for passive recreational use, the attendees enjoyed time passing footballs, frisbee, and soccer on the refurbished turf.

A portion of the park was designated as a temporary debris storage site under emergency proclamations following flooding that impacted Oʻahu in March 2026. This designation was in line with the City’s Disaster Debris Management and Operation Plan, published in April 2025. Over 18 days, roughly 3,000 tons of storm debris was deposited at the park site where it was sorted and transported to Waimānalo Gulch Sanitary Landfill and various recyclers.

The City applied environmental protections throughout the operation including filter socks to prevent runoff, temporary dust fencing and 24/7 monitoring.

An independent lab tested the soil before and after cleanup and found no harmful contaminants, meeting all Department of Health requirements. Crews then graded the site with clean soil, repaired the irrigation system and reseeded the area with grass.

A website dedicated to the temporary debris site, with more information about testing results, is available at: honolulu.gov/env/TDSR

With the removal of the temporary fencing, the full park area is now safe and open for public use. Mahalo again to the Waipi‘o and Central O‘ahu communities for their patience and understanding during this whole, roughly six-month process.

Our Wastewater Treatment and Disposal Division is preparing wastewater treatment plants across Oʻahu ahead of Hurricane Lowell.

Hurricane Lowell remains a major hurricane and is forecast to turn north this weekend, moving west of Kauaʻi and Oʻahu late Monday.

The greatest potential for direct impacts is currently focused on Kauaʻi, but islands farther east could still experience impacts, including dangerous surf and rip currents, as Lowell approaches the region.

As our crews prepare, residents are encouraged to take action too:

• Prepare your home and emergency kit.
• Review your family emergency plan.
• Monitor official forecasts and guidance.
• Sign up for HNL Alert at hnlalert.gov.

Stay informed, monitor official forecasts, and be ready to act.

Our Collection System Maintenance crews are preparing across Oʻahu ahead of Hurricane Lowell.

The latest forecast shows Lowell passing south of the Hawaiian Islands before turning north in the coming days. Although the forecast track remains uncertain, taking steps now will help ensure our crews and equipment are ready to respond to possible impacts.

Field crews are clearing the wastewater collection system, emptying debris tanks, inspecting and fueling vehicles, conducting safety briefings, and staging vacuum and cesspool trucks throughout the island. Pump station staff will also monitor conditions closely and prepare to respond to possible power outages and communication disruptions.

As our crews prepare, residents are encouraged to take action too:

• Prepare your home.
• Refresh your emergency supplies.
• Review your emergency plan with your family.
• Make sure you are prepared to be self-sufficient for at least 14 days.
• Sign up for HNL Alert at hnlalert.gov to receive emergency notifications.

Stay informed, monitor official forecasts, and be ready to act if conditions change.
