Document Description
The proposed Syphon Reservoir Improvement Project (proposed project) would increase the capacity of the existing recycled water reservoir to serve the community's seasonal and future recycled water needs. The reservoir capacity would increase from approximately 500 acre-feet (AF) to 5,000 AF. As a part of the reservoir expansion, the existing engineered dam would be replaced with a new engineered dam that would meet and exceed the latest safety standards.
