About the LWPS

The LWPS (Lightweight Water Purification System) is a tactical water treatment and purification system designed by TerraGroup Corporation for the United States Marine Corps and Special Operations Forces. The TECWAR® system is a modular, lightweight and highly mobile water purification system that is All Source Capable™, meaning that it is suitable for producing potable, safe drinking water from a wide range of sources, i.e., ponds, lakes, streams, rivers, oceans, and even water contaminated with nuclear, biological and chemical contamination. It provides absolute water purification for any field condition. It can be transported in a standard military M1097A series HMMWV; UH-60 Blackhawk helicopter; C-130 Air Transport and standard Quadcon.The system’s versatile footprint provides self-contained, potable water support without committing larger water production assets from a support structure.

There is no requirement for external power, (generators or electricity) it is totally self-contained needing only diesel fuel or gasoline, depending on the model. It can be operational in less than 45 minutes, and can be operated and maintained by one person with no special tools and minimal instruction. Basic system weight is less than 1,800 lbs, and no module is over 200 lbs, making it truly man-portable. Its versatile footprint allows 300 ft. “source to storage”, or “tailgate” configurations (and anything in between).

System flow rates range from 180 Gallons Per Hour (GPH) or 3 Gallons Per Minute (GPM) on freshwater sources to 90 Gallons Per Hour (GPH) or 1.5 Gallons Per Minute (GPM) on sea water. It is effective in producing potable water from chemical, biological, radiological, and nuclear (CBRN) contaminated sources and is designed to operate in hostile environments. The Lightweight Water Purification System is easy to operate and maintain by both trained and untrained personnel.
