GWA Update

The Guam Waterworks Authority (GWA) reports that as of 5 p.m., 98 wells are online, with 5 wells on standby power generation and 93 wells on the island-wide power system. GWA is aware of reports of low to no water pressure affecting approximately 103 customers in parts of Yigo and Dededo. GWA estimates that 43,540 customers have had water services restored – representing a restoration of approximately 99.7% of total GWA customer accounts. 

Residents are reminded that even as pressure is restored, outages and instances of low to no pressure may occur as system adjustments are still being performed to respond to the power system. GPA continues working closely with GWA to restore power to wells impacted by the storm. As reservoir levels continue to rise, service at specific locations within the distribution system may vary throughout the day. Demand during peak hours will affect the rate at which pressure can build to acceptable service levels as reservoirs fill.


GWA ENFORCING WATER CONSERVATION
In accordance with 28 GAR §2103(i): Whenever, in the opinion of GWA and in the interest of the public, special conservation measures are advisable in order to forestall water shortage and a consequent emergency, GWA may restrict the use of water by any reasonable method of control.

GWA inspectors are visiting homes and businesses to seek compliance with special water conservation measures. GWA has received voluntary compliance from homes and business establishments across the island. As GWA personnel work to restore reservoir levels and system pressure, the community is advised to practice strict water conservation during recovery efforts. Refrain from washing vehicles and pressure washing activity.


PRECAUTIONARY BOIL WATER NOTICE STILL IN EFFECT FOR SOME RESIDENTS
Results from 110 samples collected throughout the water distribution system from April 15 – 21, 2026 have returned NEGATIVE results for bacterial contamination. Samples were collected in every village.

GWA’s Utility Compliance Laboratory continues to sample the system. The precautionary boil water notice (PBWN) issued by GWA on April 16 as announced in JIC RELEASE No. 33 remains in effect for some residents, but does not apply to customers who did not experience any loss in water service. This PBWN is issued as a result of a sustained loss of pressure in parts of the island’s distribution system as a result of Super Typhoon Sinlaku. A sustained loss in pressure within the distribution system may result in potential, but unconfirmed bacterial contamination in your drinking water.

For customers who experienced a loss in water service for 48 hours or more, the PWBN is MANDATORY:

• DO NOT DRINK THE WATER WITHOUT BOILING IT FIRST.
• Bring all water to a boil, let it boil for three (3) minutes, and let it cool before using.
• Boiled water should be used for drinking, making ice, brushing teeth, washing dishes and food preparation until further notice.
• Boiling kills bacteria and other organisms in the water.

Customers who experienced a loss in water service for 48 hours or less may wish to take precaution and follow the steps listed above.


WATER TANKERS & FLEXTANKS
Residents haul water from the following sites: Astumbo Senior Center, Dededo Mayor’s Office, Chalan Palauan in Dededo, Jesus G. Cruz Street in Barrigada Heights, Gill Breeze in Yigo, Mangilao Church, Chalan Toming in Yigo, Mount Santa Rosa and Q’s Ranch in Yigo. Residents are advised to bring their own containers to store and haul water from the flextanker and tanker sites. 


GPA Update
The Guam Power Authority (GPA) provides restoration progress to the Island-Wide Power System (IWPS). As of 9:00 a.m., Wednesday, April 22, 2026:

Feeders/Circuits: A total of 63 feeders/circuits are energized today of the 63 distribution feeders/circuits.

TODAY’S KEY OBJECTIVES INCLUDE:

• All 63 feeders/circuits have been restored.
• During this stage of recovery, some energized feeders may still leave pockets of isolated customers with damages. Crews have been and continue to address the remaining isolated areas requiring more complex repairs and/or significant vegetation clearing.
• No one will be left behind. Crews have been working 12-16 hour shifts since the storm, through the day and night, for restoration efforts and will continue to work until all customers have been restored.
• As power lines heat up, weak points of the system will be apparent (e.g., storm damaged transformers, fuse cutouts, lightning arrestors, connections). Additionally, hardware components may have been loosened from the passing of the storm which may fail after power had been restored. Crews will do their best to make immediate repairs; if they cannot, they will return to make the repairs as soon as possible.
• Crews continue working on urgent needs across the island.

FOR CUSTOMERS WHO REMAIN WITHOUT POWER:

• In some areas, power may be restored to main lines while additional repairs are still needed on transformers, service lines, or customer connections.
• Customers may also be experiencing isolated damage that requires crews to return to address these additional repairs.
• If surrounding areas have power, customers may be part of a smaller outage pocket.
• Customers are asked to limit calls to the GPA Dispatch Center (PSCC) to critical issues such as downed power lines, blown transformers, low voltage conditions, or other situations that may present a safety concern. For additional assistance, customers may report these issues to GPA Customer Service via phone at (671) 648-5787/88/89, or via email at customersfirst@gpagwa.com.

GENERAL NOTIFICATIONS:

• Individuals with medical needs: Those requiring electrically powered life-support or oxygen tanks or similar devices should arrange to stay at an alternate location where electricity is available, such as a hospital or with family or friends who have power restored. Be prepared to bring your oxygen supplies, medical equipment, and medications with you.
• Personal use of generators: GPA asks that you ensure your main breakers are opened (off position) when operating your generator. This is for the safety of the crews and your equipment.
• Carbon monoxide safety hazard: It is a colorless, odorless gas that can cause serious illness or death. The risk increases during outages when generators or fuel-powered equipment are used improperly. Never use generators, grills, or portable stoves indoors. Keep equipment away from doors, windows, and vents, and never run vehicles inside garages. If you feel dizzy, nauseated, or lightheaded, move to fresh air immediately. If you suspect carbon monoxide exposure, call emergency services immediately.
• Voltage fluctuations during restoration: As power is restored, some customers may experience temporary voltage fluctuations such as flickering lights, dimming, or partial power. Customers are advised to shut off their main breaker and report the issue to GPA.
• Damaged Weatherheads and other Electrical Components: Customers are advised to conduct their own home and property assessment, including the weatherhead, meter box and other electrical components. If electrical equipment such as the weatherhead or meter box was damaged during the storm, it must be repaired before service can be restored. For more information, please contact GPA Customer Service at (671) 648-5787/88/89.
• Please stay away from all down lines and equipment as they may still be energized and can cause harm if you come in contact with the lines or equipment. Consider such situations as dangerous and life threatening. To report downed power lines, contact GPA Trouble Dispatch at (671) 475-1472/1473/1474. Customers may also email customersfirst@gpagwa.com or send a direct message on GPA’s Facebook or Instagram page. Please provide the exact location or address, contact information and condition of location when submitting your report.
