Abstract:

This paper discusses a unique water supply system for the City of Shishmaref, a moderately sized Alaska Native community on Sarichef Island in the Chukchi Sea. A three million gallon reservoir was excavated in permanently frozen sands within a small, low profile watershed. The reservoir was lined with Hypalon placed over a high density polyethylene (HDPE) underdrain system. Approximately twelve hundred feet of eight foot high 'Wyoming' snow fence was installed on the windward sides of the watershed to augment annual precipitation on the island. In addition to the reservoir, the project included a pump station, HDPE transmission line, water treatment plant, summer water distribution system, facultative sewage lagoon, and 1. 3 million gallon welded steel water storage tank.
