Pipelines
Raw water from Wells 001 and 002 is pumped through transmission pipeline and into a 2.2-million-gallon welded steel storage reservoir. Attachment II shows a water supply system schematic. The pipeline between Well 001 and 002 is 10-inches in diameter. The pipeline between system interconnection to well 401 is 16-inches in diameter.
All transmission pipelines are constructed of ductile iron pipe. Air is vented from the pipelines through aboveground air and vacuum release valves located at high points.
