EQUIPMENT DESCRIPTION AND DATA
GENERAL
The Engineer Mission Module - Water Distributor (EMM - WD) is a demountable 3000 gallon unit for use with NATO
STANAG compatible Load Handling System (LHS) type trucks (e.g., PLS M1075) and associated trailers (e.g., PLST
M1076). The Engineer Mission Module - Water Distributor (EMM - WD) is compatible for PLS transport, operation
and use throughout the mission profile. It can also be powered by an on-board diesel engine. The Engineer Mission
Module - Water Distributor (EMM - WD) when unloaded from the PLS truck is capable of operating as a wash rack
facility. The Water Distributor can be operated from the cab of the PLS vehicle when vehicle is moving or at the rear
control station when vehicle is not moving. It is composed of a 3,000 gallon stainless steel water tank mounted on
top of a slightly modified M1077 flatrack. Internal baffles in the tank minimize sloshing of material during operations.
A 20 inch manhole is located at the rear top of the tank to permit access for inspection or filling. A catwalk and hand
rails are provided to allow access to the manhole from the rear control station. An overflow pipe, located at the top
of the tank, was incorporated to prevent overfilling and to allow room for expansion of the material. A drain is located
in the bottom rear of the tank for complete draining of the unit for service or inspection. Several inlet/outlet ports are
provided with a variety of adapters for various connections and operations. The EMM - WD is intended for fresh
water operation only; saltwater shall not be used in the EMM - WD.
