a.
Determine
Hoseline
Route.A useable hoseline route must be determined prior to using the hoseline outfit.
A rapid reconnaissance and survey of proposed routings must be conducted using all available resources,
including topographic maps, aerial photographs, and actual ground inspection if possible. The minimum data
required are: a sketch of the proposed route; vehicular speedometer distances; and enough topographic
information (surveying altimeter elevations) to establish the static fluid head.
b . Route Selection.
Ideally, the hoseline should be laid out on firm, dry, level ground beyond any drainage
ditches paralleling a roadway. Select a route based on the following guidelines:
(1) Route should be direct and present a minimum number of obstacles or obstructions.
(2) Route should follow an existing roadway to facilitate hose-laying operation, and security of hoseline.
(a) A route parallel to secondary all-weather roadway is preferable to a route along a heavily traveled road.
(b) If existing roadway bends excessively, cross-country routing may be used.
(c) If no roadway is suitable, select a route which is accessible to vehicles needed for laying out hoseline.
W A R N I N G
Do not position hoseline in an area where leakage can contaminate drinking
water. Failure to observe this warning can result in serious injury or death by
p o i s o n i n g.
(d) Do not route hoseline through marshes, swamps, water courses, or land subject to periodic flooding.
(3) Plan the location of any necessary take-off tees.
(4) In rolling country, the hoseline is most effective where the elevation varies no more than 100 feet per
13,000 feet (30m per 3,900 m). If increase in elevation of the line is too great, then either a reduction in
flow must be accepted or, the hoseline shortened.
(5) Depending upon the situation in which the hoseline is to be used, the following basic security
precautions should be considered when planning the hoseline route.
C A U T I O N
(a)
(b)
(c)
(d)
Do not lay hoseline on areas of exposed rock. Hoseline is easily damaged by
sharp edges or abrasive action of rock.
Do not route the hoseline through densely populated areas.
Take full advantage of natural cover (fence lines, woods, hedging, etc.).
Disturb the natural cover as little as possible.
Do no leveling or grading.
