Preface
SCOPE
This manual provides the latest approved doctrine for rigging the following water purification units.
It is written for use by all parachute riggers.
a. 600-gallons per hour (GPH) ROWPU on a 20-foot platform.
b. Lightweight water purifier (LWP) on a 12-foot platform.
NOTICE OF EXCEPTION
When an item of airdrop equipment is replaced or a rigging procedure is changed, it will be impossible
to change all manuals in the field at one time. Therefore, FM 4-20.102/NAVSEA SS400-AB-MMO-
010/TO 13C7-1-5 will be changed when necessary and will take precedence over the procedures in
an individual rigging manual. There may be times, however, when the procedures in an individual
rigging manual must be followed even though they are different from those in FM 4-20.102/NAVSEA
SS400-AB-MMO-010/TO 13C7-1-5. When this occurs, a notice of exception will be printed at the
beginning of each paragraph where the exception is authorized. The notice of exception will look
like the following:
NOTICE OF EXCEPTION
The procedures in this paragraph are different from those
in FM 4-20.102/NAVSEA SS400-AB-MMO-010/TO13C7-
1-5. An exception to FM 4-20.102/NAVSEA SS400-AB-
MMO-010/TO 13C7-1-5 is granted. The procedures in this
paragraph must be followed.
REFERENCE INFORMATION
To avoid repeating certain information and procedures, it is often necessary to reference other FMs
and TMs. For example, this manual often references FM 4-20.102/NAVSEA SS400-AB-MMO-010/
TO 13C7-1-5. This may seem to be contradictory in that this manual, FM 4-20.158/TO 13C7-7-61,
deals with rigging water purification loads and FM 4-20.102/NAVSEA SS400-AB-MMO-010/TO
13C7-1-5 deals with rigging platform loads. However, FM 4-20.102/NAVSEA SS400-AB-MMO-010/
TO 13C7-1-5 also provides general information and general procedures. Where procedures are the
same or only minor differences exist it is permissible to state that the procedure is done according
to or by adapting the procedures in FM 4-20.102/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5.

Introduction
DESCRIPTION OF ITEMS
The description of the items rigged in this manual is given below.
a. 600-Gallons Per Hour (GPH) Reverse Osmosis Water Purification
Unit (ROWPU): The ROWPU consists of a water purification unit and a 30-
kilowatt generator mounted on a 5-ton, four wheel, cargo trailer. The ROWPU
with supporting equipment weighs 21,780 pounds rigged. It is 230 inches long
and 96 inches wide. Its height is 97 inches (reducible to 91 inches).
b. Lightweight Water Purifier (LWP): The lightweight water purifier
consists of a loading truck, ultra-filtration module, control module, high-pres-
sure pump module, chemical injection cleaning module, reverse osmosis element
module, pump module, 3-kilowatt (KW) generator, loading ramps, 1,000 gallon
collapsible fabric tank (raw water and product), hose (raw water, back-wash,
high-pressure and reject), pump skid cover, components of end items (COEI)
box, basic issue items (BII) box, cold weather kit (CWK) 1 box, cold weather kit
(CWK) 2 box, CWK 3 box and the components of end items (COEI) cable box.
The total weight of the LWP is approximately 6,140 pounds.
SPECIAL CONSIDERATIONS
Special considerations for this manual are given below.
a. The 600-GPH ROWPU is technically approved for airdrop from the C-130
and C-17 aircraft.
b. The overall rigged height of the 600-GPH ROWPU will not exceed 101 inches
for a distance of not more than 40 inches aft of the CB. All high points should be
verified each time this load is placed on the aircraft.
c. A copy of this manual must be available to the joint airdrop inspectors during
the before- and after- loading inspections.
d. Check fuel levels to ensure that they do not exceed the the fuel level of the
specific rigging chapter.
e. Package, mark, and label hazardous material according to AFMAN 24-204(I)/
TM 38-250.
