(a) Heavy divisions (TOE 42-007L00). The water section of armored, infantry, and
mechanized divisions has all of the equipment in Table 2:
Table 2. Equipment in TOE 42-007L00
Normally, this configuration of equipment gives the water section the ability to set up one water
purification site in each BSA and two water purification sites in the DSA (two ROWPUs per site, three
tanks per ROWPU) as well as dry points using the SMFTs. Planners estimated two round-trips per day
for distribution. Planners are now rating the 600-GPH ROWPU as able to produce 900 GPH from a
freshwater source and 600 GPH from a saltwater source (Potable Water Guide, March 1997).
(b) Other divisions will have similar equipment. The 600-GPH ROWPU is designed
for divisional use and quantity will vary, depending on the type of division. Each 600-GPH ROWPU
comes with three 3,000-gallon onion tanks. In both divisional and nondivisional units, the FAWPSS is
used primarily for limited aerial delivery to isolated units.
(c) In certain cases, such as desert operations, there may be only one water source for
the division, and it is conceivable that the source may not be within the DSA. These situations may
warrant the setup of GS water supply systems. In such a situation, the water supply sections in CSS
units will be augmented with additional equipment and personnel to operate PWS/DS. Purified water
will be delivered to the supported unit by SMFTs. This augmentation package consists of one 300,000-
gallon PWS/DS for the DSA and one 40,000-gallon PWS/DS for each BSA. Also, units with the
requirement will receive additional FAWPSSs to assist in the water resupply mission. This equipment
will be transported on the SMFT trailers and on the cargo beds of the ROWPU 5-ton prime mover. As
divisions change tactical areas of operation in an arid environment, water source opportunities may
develop. To exploit these water sources, divisions may be augmented with GS purification teams.
