This service will be available Monday through Friday for the duration of the Government of Guam shut down due to the coronavirus outbreak.

Since the drive-thru opened on Monday, March 23rd GWA has seen a steady increase in the number of our customers using this service. In the interest of reducing wait times, GWA will now open at 6:30 a.m. GWA and GPA appreciate customers’ commitment to paying their utility bills despite this on-going crisis.

GWA encourages everyone to observe the social isolation directive by using pay by phone, mobile app, online payment or drop-box options and only utilize the drive-thru service as a last resort.
