Restore Asan Springs Water Supply Facility
War in the Pacific National Historical Park » Restore Asan Springs Water Supply Facility » Document List
The National Park Service (NPS) invites the public to provide comments on the Environmental Assessment (EA) on the proposed project to restore the Asan Springs water supply facility, which is partially on NPS lands in Asan village. The Guam Waterworks Authority (GWA) is proposing to restore the facility to increase input to the Agana-Asan-Piti Integrated Water Supply and Storage System to meet water supply demands in west central Guam. The NPS is proposing to issue GWA a permit to rehabilitate the existing impoundment structure; demolish the exiting chlorination building and construct a new one; install an 8-foot-high fence surrounding the facility; construct a concrete drainage swale surrounding the upper limits of the facility; demolish and remove outdated and damaged components and debris; replace/install new electrical and waterlines; and make other repairs as needed. The NPS would also issue GWA a Right of Way permit to access, operate, and maintain the facility for a period of 10 years (may be renewed).
The concrete reservoir was constructed by the U.S. Navy in 1916 to impound the flow from the Asan Springs. Since then, it was improved by adding a pump station and chlorinator building. However, it was shut down in 2004 due to bacterial contamination and inadequate chlorination to treat the water. This project would upgrade the existing system to provide a clean dependable water source meeting water quality standards, reduce the demand for additional wells and pumping systems, and avoid purchasing water from the Navy for villages that could be supplied with Asan Springs water.
Other options proposed by the Guam Waterworks Authority include:
• rehabilitation and restart of the existing system,
• closure of the existing system with installation of a new well and pumping system,
• abandonment of the system with installation of a new well and pumping system, and
• taking no action.
