Site Requirements.
a.
Terrain. Prior to installing TWDS equipment, a thorough study of the terrain is required. A general route for
hoseline and general locations for the pumping stations, storage assemblies, and distribution points can be
determined from examination and comparison of maps, photographs, and charts. Some elements to be considered
in selecting a route and installation sites for TWDS are:
(1) If TWDS will operate independently or as part of a large system.
(2) The assigned mission for TWDS (i.e., dispensing, storing, or transferring water).
(3) Expected length of time TWDS will be required to operate.
(4) Elevation differences and distances TWDS will encounter along its route.
b.
Site Location. Organize ground reconnaissance prior to installation of TWDS to determine exact locations for
pumping stations, storage assemblies, and distribution points. If possible, site locations should be near or parallel
to existing roads to ease transportation, assembly,-inspection, maintenance, and disassembly of the system. Avoid
routes along the banks of streams, marshes, ponds, gullies, ravines, or other areas subject to flooding. Whenever
possible, the hoseline should be laid out on firm, dry, level ground that allows easy access and is not subject to
