As of 2 p.m. Friday, the Guam Waterworks Authority (GWA) reported 80 wells online, with 27 running on the island-wide power system and 53 on generator power.
In an update on restoration efforts following Super Typhoon Bavi, GWA said it is collaborating with the Federal Emergency Management Agency (FEMA), Guam Homeland Security/Office of Civil Defense and the U.S. Army Corps of Engineers, which joined GWA crews to assess emergency power needs for water and wastewater facilities.
“Assessments will lead to support generator installations at critical D-, F-, M- and Y-series production wells,” the update states.
GWA also reported 19 booster pumps online — four on island power and 15 on generator power. The Ugum Surface Water Treatment Plant, Santa Rita Springs and the Tumon Maui well remain online on generator power. Four wastewater treatment plants are operational, with only one on island-wide power. 79 sewer pump stations are online, 50 on generator power.
99 water samples collected July 7-8 tested negative for total coliforms. Two additional samples collected in Santa Rita on Friday will be tested, with results shared as they become available.
Water to parts of Santa Rita has been restored, though adjustments are ongoing to restore pressure.
A boil water notice is in effect for customers who sustained water loss for 48 hours or more during the storm.
Seven water tankers and flexitanks are deployed in Mangilao, Dededo, Yigo, Talofofo, Yona, Mongmong and Barrigada, with an additional tanker heading to Piga Subdivision in Dededo after 3 p.m. Friday.
