This is accomplished through the professional, reliable, and certified operators of Guam Waterworks Authority.
The Ugum Surface Water Treatment Plant (USWTP) Section operates and maintains GWA’s only surface water production facility, which pumps raw river water up to the plant and through several steps of its membrane filtration treatment and chlorine disinfection processes. This process produces clean, safe, potable water which is stored at the plant’s reservoir and released into the distribution system, serving the southern area of Guam from the villages of Ipan to Umatac. The USWTP is designed to produce up to 4 Million Gallons per Day (MGD) but currently produces 2.3 MGD to meet customer demand.
The Production/Treatment Division also operates and maintains the GIAA Public Water Supply System through an operating agreement between GWA and the Airport Authority.

FOG stands for Fats, Oil and Grease. Grease is the common term for animal fats and vegetable oils. Why is FOG A Problem? When grease enters our sewer system, it acts much the same way as it does when it sticks to your pots and pans – it collects on the pipe walls and builds up until there is a clog. When a sewer line clogs, the pressure has to be released somewhere. Generally this is the lowest point available – which may mean backing up into the establishment that caused the grease, or in another building between there and the back-up. The sewage may also find a manhole and overflow – in which case it is not only a serious public health hazard, but if it gets into a storm drain and into the ocean, it’s an environmental problem as well.
