TACTICAL WATER PURIFICATION SYSTEM (TWPS)
DESCRIPTION AND THEORY OF OPERATION
EQUIPMENT DESCRIPTION AND DATA
Five extended capability modules are available for issue and deployment separately as required by the
mission profile. The five extended capability Marine Corps modules are:
Cold Weather Module: deployed for operating environments below 32 0F.
Supplemental Cleaning Waste Storage Module: used to temporarily store the wastes that
result from cleaning the micro-filters (MF) and the reverse osmosis (RO) elements.
Ocean Intake Structure System (OISS) Module: deployed at beach locations that are exposed
to wave action and at ocean locations with significant tidal variations.
NBC Water Treatment Module: contains the filter media required for final treatment of a raw
water source that is contaminated with nuclear, biological or chemical warfare agents.
The components of each of the five extended capability modules are identified near the end of this work
The A-TWPS (shown packed out for deployment closed and open in Figure 5) is mounted within an 8 x 8
x 20 ISO load handling shelter that is referred to as the "flat rack". The A-TWPS includes the basic TWPS
skid, all BII, all of the features provided by the five extended capability modules described for the Marine
Corps version, a 60 kW Tactical Quiet Generator (TQG) NSN 6115-01-274-7390 and an extended
distribution kit. The extended distribution kit makes it possible to increase potable water storage capacity
from the standard 6,000 gallons to a total capacity of 15,000 gallons and increase total distribution flow
from 125 gpm through two nozzles to 250 gpm through four nozzles. The A-TWPS is compatible with the
PLS truck (M1074, M1075), HEMTT LHS truck (M1120), and PLS trailer (M1076) for transport.
