The Guam Waterworks Authority (GWA) reports that as of 6 p.m., 95 of 98 wells are online, with 5 wells on standby power generation and 90 wells on the island-wide power system. GWA is aware of multiple reports of low to no water pressure affecting approximately 852 customers across the island - predominantly in parts of Yigo and Dededo. GWA estimates that 42,818 customers have had water services restored. In areas where water service has been restored, isolated parts of those areas may still experience low to no pressure from damaged service lines. To report a damaged water service line, call GWA Dispatch at 671-646-4211.
Residents are reminded that even as pressure is restored, outages and instances of low to no pressure may still occur as system adjustments are still being performed to respond to the power system. The Guam Power Authority (GPA) continues working closely with GWA to restore power to wells impacted by the storm. Residents are further reminded that reservoir levels are in recovery and service at specific locations within the distribution system may vary throughout the day. Customer demand during peak hours will affect the rate at which pressure can build to acceptable service levels as reservoirs are still filling.
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 or flushing driveways and sidewalks and limit water use in the kitchen and bathroom. Non-essential water usage may place unnecessary stress on pressure within the water distribution system.
Additionally, there may be an increased risk of backups and sewer overflows as wastewater pump and plant operations have been affected by the storm – reducing proper collection of wastewater from customers connected to GWA’s sewer.
PRECAUTIONARY BOIL WATER NOTICE STILL IN EFFECT FOR SOME RESIDENTS
Results from 101 samples collected throughout the water distribution system from April 15 – 20, 2026 have returned NEGATIVE results for bacterial contamination. Sample collection was performed in parts of Agana Heights, Assan-Ma’ina, Barrigada, Barrigada Heights, Dededo, Hagåt, Hagåtña, Harmon, Inalåhan, Mangilao, Malesso’, Malojloj, Nimitz Hill, Piti, Sånta Rita-Sumai, Talo’fo’fo, Tamuning, Tumon, Yona, and Yigo.
GWA’s Utility Compliance Laboratory will sample more of the system as water continues to be restored throughout the island. Results will be reported once analysis is complete. 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:
The PBWN 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.
Customers who experienced a loss in water service for 48 hours or less may wish to take precaution and are advised of the following:
- 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.
For customers who experienced a loss in water service for 48 hours or more, it is MANDATORY to boil your water and:
- 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.
Bacterial contamination can occur when increased run-off enters the drinking water source, if there is a loss of line pressure to less than 5psi, prolonged, sustained loss of water service, or failure in the water treatment process.
WATER TANKERS & FLEXTANKS
Tankers and flextanks have been staged in different parts of the island. Residents haul water from the following sites: Chalan Okso on Route 15, Astumbo Senior Center, Dededo Mayor’s Office, Chalan Paluan in Dededo, Jesus G. Cruz Street in Barrigada Heights, Gill Breeze in Yigo, Piga Subdivision, Mangilao Church, Chalan Toming/La Chance Yigo, the Yigo gym and Mount Santa Rosa in Yigo. Residents are advised to bring their own containers to store and haul water from the flextanker and tanker sites.
