GENERAL SUMMARY
● The majority of the island’s water production comes from the Northern Water Wells, which then travels through a series of pipes and reservoirs to the Central and Southern parts of the island.
● Currently 101 wells (84% of operable wells are on-line) and producing approximately 35 million gallons of water per day (approximately 103% of pre-typhoon production).
● Guam’s water system relies on adequate water levels in the reservoirs in order for there to be enough pressure to push the water throughout the island.
● Once enough wells have been brought online, and water production sufficiently exceeds demand, GWA will have enough water to fill the reservoirs and provide sufficient pressure to distribute water island wide.
● GWA reminds those residents WITH water service to please conserve water and avoid washing cars, water blasting and other non-essential high water-usage activities to assist with rebuilding reservoir levels and restoring water service island wide.
● GWA continues to work to replace pumps and motors in 8% of wells. One GWA crew and one crew made up of GWA, and maintenance contractors. Each changeout takes approximately 12 to 16 hours to complete.
● GWA has restored water to 95.6% of customers and asks for your patience as we work to restore our system to pre-storm conditions.

REGIONAL WATER SYSTEM UPDATE
Here is the most recent update on GWA water restoration progress:

Northern Region:
● The Northern water system facilities are operating normally, although reservoir levels remain low.
● 74 wells are currently operating on island power, while 27 are operating on generator power.
● GWA experienced a setback yesterday with interrupted production due to rolling power outages causing the Yigo and Santa Rosa Reservoir levels dropping to near zero levels. This interrupted our ability to pump water to higher elevations of Mt. Sta. Rosa, which remains without water this morning. Additionally, due to the continued low pressure Yigo (LaChance, Chalan Chaguian areas), Dededo (Finegayan, Fern Terrace, Chalan Palauan. These areas are still under GWA’s Precautionary Boil Water Notice.

Central Region:
GWA was able to sustain nominal levels in key reservoirs for the Central system, providing some relief to higher areas in Mangilao (including Latte Heights, Latte Plantation areas), Ordot-Chalan Pago (Dero Rd. above LeoPalace access, Chilenko St./Sta. Cruz Dr. to Manibusan Lane and adjacent side streets). However, until pressures stabilize, these areas also remain under the Precautionary Boil Water Notice. Barrigada (PC Lujan area, Jackson St. off Rte. 8, Jesus T. Iriarte St. off Rte. 16) are still under GWA’s Precautionary Boil Water Notice are affected by Yigo and Santa Rosa Reservoir levels dropping to near zero levels.

Southern Region:
● The Ugum Surface Water Treatment Plant continues to operate at a reduced capacity, producing approximately 2 million gallons of water per day when in operation.
● Ugum SWTP crews will continue to maintain reservoir levels during periods of low demand.
● Water services restored from Ipan to Umatac

WASTEWATER SYSTEM UPDATE
The Northern District, Agat-Santa Rita, Umatac-Merizo, Hagåtña and Inarajan Wastewater Treatment Plants are all operating normally.

Although several sewer pump stations were returned to island power, some GWA facilities remain on generator power, and GWA is working with GPA to monitor power status at both GWA wastewater pump stations and treatment plants.

Sewer system overflows may occur as pump station sites may become inundated or lose power during restoration of service. GWA is reporting these overflows to EPA and cautions the public to avoid contact with suspected sewage overflows. GWA is also responding to reports of sewage overflows at private pump station facilities or blocked private sewer mains and is assisting where it can.

CURRENT PRIORITIES
● Water system adjustments and restoration at remaining problematic service areas
● Deepwell Operations & Pump/Motor Changeouts
● Repairs to reported leaks and damaged laterals.

Precautionary Boil Water Notice:

GWA Water System

BOIL YOUR WATER BEFORE USING

Due to the impact to GWA’s Water system from Typhoon Mawar portions of the water system have experienced reduced pressure which may pose a risk to customers. Out of an abundance of caution, GWA issues this Precautionary Boil Water Notice while GWA restores the water system and laboratory analysis confirms the water is safe to drink.

What should I do? What does this mean?

● 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 or use bottled water. Boiled or bottled 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.
● Fecal coliforms and E. coli are bacteria whose presence indicates that water may be contaminated with human or animal wastes. Microbes in these waters can cause diarrhea, cramps, nausea, headaches, or other systems. They pose a special health risk for infants, young children, and people with severely compromised immune systems.
● The systems above are not caused only by organisms in drinking water. If you experience any of these symptoms and they persist, you may want to seek medical advice. People at increased risk should seek advice about drinking water from their health care providers.

What is being done?
Bacterial contamination can occur when increased run-off enters the drinking water source, if there is a loss of line pressure to less than 5 psi, a pipe break lasted more than 12 hours or there is a failure in the water treatment process. This advisory is being issued as a precaution while GWA works to bring all production facilities back into service and replenish water tank levels to increase pressure in the system. As production and pressure in the system is restored, GWA will ensure that the system is sampled and tested, and chlorine levels and pressures have been confirmed to be within acceptable levels.

GENERAL SUMMARY
● The majority of the island’s water production comes from the Northern Water Wells, which then travels
through a series of pipes and reservoirs to the Central and Southern parts of the island.
● Currently 91 wells (76% of operable wells are on-line) and producing approximately 32 million gallons of
water per day (approximately 93% of pre-typhoon production).
● Guam’s water system relies on adequate water levels in the reservoirs in order for there to be enough
pressure to push the water throughout the island.
● Once enough wells have been brought online, and water production sufficiently exceeds demand, GWA will
have enough water to fill the reservoirs and provide sufficient pressure to distribute water island wide.
● GWA reminds those residents WITH water service to please conserve water and avoid washing cars, water
blasting and other non-essential high water-usage activities to assist with rebuilding reservoir levels and
restoring water service island wide.

● The Ugum Surface Water Treatment Plant continues to operate at reduced capacity due to damaged control
equipment, producing approximately 1340 gallons per minute, but service areas will be subject to temporary
outages during periods of high demand.
● The Southern Water System continues to meet demand, but the GWA Pressure Line Unit battled to repair two
main line breaks in Merizo and Santa Rita.
● Power fluctuations caused some interruptions to some sites, but that is to be expected during recovery
operations.

● The majority of the island’s water production comes from the Northern Water Wells, which then travels through a series of pipes and reservoirs to the Central and Southern parts of the island.
● Currently 73% of operable wells are on-line and producing approximately 31.5 million gallons of water per day. (Normal system operation is between 34-36 million gallons per day).
● Guam’s water system relies on adequate water levels in the reservoirs in order for there to be enough pressure to push the water throughout the island.
● Once enough wells have been brought online, they will be able to produce adequate water supply, providing enough water to fill the reservoirs and provide sufficient pressure to distribute water island wide.
● GWA reminds those residents WITH water service to please conserve water and avoid washing cars, water blasting and other high water-usage activities to assist with rebuilding reservoir levels and restoring water service island wide.
● GWA is experiencing issues with generators at certain facilities and has made a request for FEMA generators and a fuel tanker dedicated to delivering fuel to GWA assets.
● GWA continues to work with federal agencies to assess and install additional generators where needed.
● GWA continues to implement multiple strategies to bring as many wells online as quickly as possible including:

1. GPA energizes areas were deepwells are located

2. GPA, GWA, and maintenance contractors continue to repair existing generators.

3. FEMA generators are requested for well sites where genset repairs cannot be made quickly. Sites are prioritized based on production levels and levels of damage to the island wide power system in those areas.

4. Two crews are working to replace pumps and motors in 21 wells. One GWA crew and one crew made up of GWA, GPA and maintenance contractors. Each changeout takes approximately 12 to 16 hours to complete.

● 14% of wells require pump and motor replacements, which have been approved by the EPA and began Wednesday, May 31.
● GWA continues to operate all available wells to increase reservoir levels throughout the northern system and send more water to the Central system.
● Crews restored water service to Mount Santa Rosa this afternoon.

Central Region:
● GWA sources and Navy-supplied sources continue to supply Santa Rita and Agat, except in the high-elevation areas of Santa Ana, which are in the process of being restored.
● Service on Cross-Island Road area restored to the Sumay Memorial.
● Talofofo main village has been restored but remains susceptible to outages as reservoir levels drop during times of high demand — GWA crews continue to monitor the system in the area.
● Tumon, Tamuning, Chalan Pago and Sinajana will continue to experience intermittent service disruption during peak demand times.
● Barrigada is now receiving consistent service, but with low water pressure.
● Crews are still working to restore service to the higher elevated areas in the M-T-M area above Benson.
● Mangilao has service in the low elevation areas and continues to have partial service in the higher elevation areas, such as Corten Torres St (BPM area), UOG, and Mariano St. area.
Generally, these areas have water in the evening, with low to no water service by morning.

Southern Region:
● The Ugum Surface Water Treatment Plant continues to operate at reduced capacity due to damaged control equipment, producing approximately 1340 gallons per minute, but service areas will be
subject to temporary outages during periods of high demand.
● The Southern Water System continues to meet demand, but the GWA Pressure Line Unit battled to repair two main line breaks in Merizo and Santa Rita.
● Power fluctuations caused some interruptions to some sites, but that is to be expected during recovery operations.
● Restoration progress continues to be made in Agat in the Santa Ana area.

WASTEWATER SYSTEM UPDATE
The Northern District, Agat-Santa Rita, Umatac-Merizo, Hagåtña Wastewater Treatment Plants are all operating normally. The Inalåhan Wastewater Treatment Plant is without power.

Although several sewer pump stations were returned to island power, some GWA facilities remain on generator power, and GWA is working with GPA to monitor power status at both GWA wastewater pump stations and treatment plants.

Sewer system overflows may occur as pump station sites may become inundated or lose power during restoration of service. GWA is reporting these overflows to EPA and cautions the public to avoid contact with suspected sewage overflows.

CURRENT PRIORITIES
• Deepwell Operations & Pump/Motor Changeouts
• Water System Restoration
• Water Tanker service to dialysis centers and clinics
• Water Tanker deployment for pocket outages

VILLAGE WATER STATIONS
GWA has deployed ten 6000-gallon Flexible Potable Water Tanks and one 6800-gallon tanker in:

Precautionary Boil Water Notice:

GWA Water System

BOIL YOUR WATER BEFORE USING

Due to the impact to GWA’s Water system from Typhoon Mawar portions of the water system have experienced reduced pressure which may pose a risk to customers. Out of an abundance of caution, GWA issues this Precautionary Boil Water Notice while GWA restores the water system and laboratory analysis confirms the water is safe to drink.

What should I do? What does this mean?

● 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 or use bottled water. Boiled or bottled 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.
● Fecal coliforms and E. coli are bacteria whose presence indicates that water may be contaminated with human or animal wastes. Microbes in these waters can cause diarrhea, cramps, nausea, headaches, or other systems. They pose a special health risk for infants, young children, and people with severely compromised immune systems.
● The systems above are not caused only by organisms in drinking water. If you experience any of these symptoms and they persist, you may want to seek medical advice. People at increased risk should seek advice about drinking water from their health care providers.

What is being done?
Bacterial contamination can occur when increased run-off enters the drinking water source, if there is a loss of line pressure to less than 5 psi, a pipe break lasted more than 12 hours or there is a failure in the water treatment process. This advisory is being issued as a precaution while GWA works to bring all production facilities back into service and replenish water tank levels to increase pressure in the system. As production and pressure in the system is restored, GWA will ensure that the system is sampled and tested, and chlorine levels and pressures have been confirmed to be within acceptable levels.

GENERAL SUMMARY
● The majority of the island’s water production comes from the Northern Water Wells, which then travels through a series of pipes and reservoirs to the Central and Southern parts of the island.
● Currently 70% of operable wells are on-line and producing water.
● Guam’s water system relies on adequate water levels in the reservoirs in order for there to be enough pressure to push the water throughout the island.
● Once enough wells have been brought online, they will be able to produce adequate water supply, providing enough water to fill the reservoirs and provide sufficient pressure to distribute water island wide.
● GWA reminds those residents WITH water service to please conserve water and avoid washing cars, water blasting and other high water-usage activities to assist with rebuilding reservoir levels and restoring water service island wide.
● GWA is experiencing issues with generators at certain facilities and has made a request for FEMA generators and a fuel tanker dedicated to delivering fuel to GWA assets.
● GWA continues to work with federal agencies to assess and install additional generators where needed.
● GWA continues to implement multiple strategies to bring as many wells online as quickly as possible including:

1. GPA energizes areas were deepwells are located

2. GPA, GWA, and maintenance contractors continue to repair existing generators.

3. FEMA generators are requested for well sites where genset repairs cannot be made quickly. Sites are prioritized based on production levels and levels of damage to the island wide power system in those areas.

4. Two crews are working to replace pumps and motors in 21 wells. One GWA crew and one crew made up of GWA, GPA and maintenance contractors. Each changeout takes approximately 12 to 16 hours to complete.

REGIONAL WATER SYSTEM UPDATE
Here is the most recent update on GWA water restoration progress:

Northern Region:
● The Northern water system facilities are operating normally, but at reduced capacity due to only 70% of wells having access to island or generator power.
● Crews are working to restore 5% of wells needing power, minor repairs or increase of flow.
● 17% of wells require pump and motor replacements, which have been approved by the EPA and began Wednesday, May 31.
● GWA continues to operate all available wells to increase reservoir levels throughout the northern system and send more water to the Central system.
● Crews restored water service to Mount Santa Rosa this afternoon.

Precautionary Boil Water Notice:

GWA Water System

BOIL YOUR WATER BEFORE USING

Due to the impact to GWA’s Water system from Typhoon Mawar portions of the water system have experienced reduced pressure which may pose a risk to customers. Out of an abundance of caution, GWA issues this Precautionary Boil Water Notice while GWA restores the water system and laboratory analysis confirms the water is safe to drink.

What should I do? What does this mean?

● 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 or use bottled water. Boiled or bottled 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.
● Fecal coliforms and E. coli are bacteria whose presence indicates that water may be contaminated with human or animal wastes. Microbes in these waters can cause diarrhea, cramps, nausea, headaches, or other systems. They pose a special health risk for infants, young children, and people with severely compromised immune systems.
● The systems above are not caused only by organisms in drinking water. If you experience any of these symptoms and they persist, you may want to seek medical advice. People at increased risk should seek advice about drinking water from their health care providers.

What is being done?
Bacterial contamination can occur when increased run-off enters the drinking water source, if there is a loss of line pressure to less than 5 psi, a pipe break lasted more than 12 hours or there is a failure in the water treatment process. This advisory is being issued as a precaution while GWA works to bring all production facilities back into service and replenish water tank levels to increase pressure in the system. As production and pressure in the system is restored, GWA will ensure that the system is sampled and tested, and chlorine levels and pressures have been confirmed to be within acceptable levels.

GENERAL SUMMARY
● The majority of the island’s water production comes from the Northern Water Wells, which then travels through a series of pipes and reservoirs to the Central and Southern parts of the island.
● Currently 58% of operable wells are on-line and producing water — GPA made great progress restoring circuits and getting more wells restored to island power.
● Guam’s water system relies on adequate water levels in the reservoirs in order for there to be enough pressure to push the water throughout the island.

Precautionary Boil Water Notice:

GWA Water System

BOIL YOUR WATER BEFORE USING

Due to the impact to GWA’s Water system from Typhoon Mawar portions of the water system have experienced reduced pressure which may pose a risk to customers. Out of an abundance of caution, GWA issues this Precautionary Boil Water Notice while GWA restores the water system and laboratory analysis confirms the water is safe to drink.

What should I do? What does this mean?

● 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 or use bottled water. Boiled or bottled 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.
● Fecal coliforms and E. coli are bacteria whose presence indicates that water may be contaminated with human or animal wastes. Microbes in these waters can cause diarrhea, cramps, nausea, headaches, or other systems. They pose a special health risk for infants, young children, and people with severely compromised immune systems.
● The systems above are not caused only by organisms in drinking water. If you experience any of these symptoms and they persist, you may want to seek medical advice. People at increased risk should seek advice about drinking water from their health care providers.

What is being done?
Bacterial contamination can occur when increased run-off enters the drinking water source, if there is a loss of line pressure to less than 5 psi, a pipe break lasted more than 12 hours or there is a failure in the water treatment process. This advisory is being issued as a precaution while GWA works to bring all production facilities back into service and replenish water tank levels to increase pressure in the system. As production and pressure in the system is restored, GWA will ensure that the system is sampled and tested, and chlorine levels and pressures have been confirmed to be within acceptable levels.

GENERAL SUMMARY
● The majority of the island’s water production comes from the Northern Water Wells, which then travels through a series of pipes and reservoirs to the Central and Southern parts of the island.
● Currently 55% of operable wells are on-line and producing water
● Guam’s water system relies on adequate water levels in the reservoirs in order for there to be enough pressure to push the water throughout the island.
● Once enough wells have been brought online, they will be able to produce adequate water supply, providing enough water to fill the reservoirs and provide sufficient pressure to distribute water islandwide.
● GWA reminds those resident WITH water service to please conserve water and avoid washing cars, water blasting and other high water-usage activities to assist with rebuilding reservoir levels and restoring water service islandwide.
● GWA is experiencing issues with generators at certain facilities and has made a request for FEMA generators and a fuel tanker dedicated to delivering fuel to GWA assets.

● Humåtak restoration efforts are ongoing
● Main break repairs completed in Inalåhan
● Due to heavy rain conditions, the Ugum Surface Water Treatment Plant was shut down for a brief time due to high turbidity of the Ugum River. The plant will continue to run intermittently, and will come on-line full time once the turbidity in the river has subsided.

WASTEWATER SYSTEM UPDATE
The Northern District, Umatac-Merizo, Hagåtña and Inalåhan Wastewater Treatment Plants are all receiving flow and functioning normally, although with some reduced capacity.

The Agat-Santa Rita Wastewater Treatment Plant is processing flow, but currently without power. The plant will operate normally once power is restored.

Some booster pump stations are currently without power, and are unable to carry wastewater to the wastewater treatment plants. These stations have been identified and will be operational once power is restored.

If you encounter a sewer overflow, avoid contact.

Precautionary Boil Water Notice:

GWA Water System

BOIL YOUR WATER BEFORE USING

Due to the impact to GWA’s Water system from Typhoon Mawar portions of the water system have experienced reduced pressure which may pose a risk to customers. Out of an abundance of caution, GWA issues this Precautionary Boil Water Notice while GWA restores the water system and laboratory analysis confirms the water is safe to drink.

What should I do? What does this mean?

● 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 or use bottled water. Boiled or bottled 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.
● Fecal coliforms and E. coli are bacteria whose presence indicates that water may be contaminated with human or animal wastes. Microbes in these waters can cause diarrhea, cramps, nausea, headaches, or other systems. They pose a special health risk for infants, young children, and people with severely compromised immune systems.
● The systems above are not caused only by organisms in drinking water. If you experience any of these symptoms and they persist, you may want to seek medical advice. People at increased risk should seek advice about drinking water from their health care providers.

What is being done?
Bacterial contamination can occur when increased run-off enters the drinking water source, if there is a loss of line pressure to less than 5 psi, a pipe break lasted more than 12 hours or there is a failure in the water treatment process. This advisory is being issued as a precaution while GWA works to bring all production facilities back into service and replenish water tank levels to increase pressure in the system. As production and pressure in the system is restored, GWA will ensure that the system is sampled and tested, and chlorine levels and pressures have been confirmed to be within acceptable levels.
