A single ROWPU costs the USAF just over $750K to own and operate during its lifecycle. With an inventory of over 270 units, that’s nearly $203M.
How does a Rowpu work?
The ROWPU is an advanced water treatment system that is capable of purifying any water source. The functioning of this system is based on the reverse osmosis principal. It can be used to treat water contaminated by nuclear-biological-chemical warfare agents, as well as fresh, brackish and seawater.
How much water does TWPS?
The Tactical Water Purification System (TWPS) uses state-of-the-art reverse osmosis technology to produce 1,500 gallons per hour (GPH) of potable water from any source, including salt water and nuclear, biological, and chemical (NBC) contaminated water.
How many gallons of water does a soldier drink a day?
Five quarts of water per day for 1,000 soldiers equals 5,000 quarts, or 1,250 gallons of water. That amounts to filling 250 five-gallon water cans per day. For the more-active troops, eight quarts per day are needed.
Is RO water expensive?
Reverse osmosis filtered water costs about $3.50 per 1,000 gallons or about $0.004 per gallon.

What is the goal of shower and laundry units for providing showers and laundry per person per week?
A 10% loss factor, comprised of 4% evaporation and 6% waste/spillage, is required through all environments. Two showers and up to 15 pounds of laundry will be provided to each individual per week.
How much ice does a soldier need per day?
ICE. Ice is forecasted per person, per day based on the operational environment. The pounds per bag per person vary with each climate. Arid climates require 6 pounds per person; tropic, 5 pounds; temperate, 4 pounds; and arctic, 3 pounds.
Do soldiers still carry canteens?
Each soldier carries two camouflage-green, kidney-shaped plastic canteens that hold one quart of water each. These canteens clip to their belts, one on either side. They also have an optional two-quart canteen in their pack.
What does ROWPU stand for?
–Fresh Water Purifier (ERDLATOR) •Use of multiple units led to logistics and training problems •US Government funded research in Reverse Osmosis led to fielding of Reverse Osmosis Water Purification Units (ROWPUs) in the 1980’s Unclassified/FOUO Soldier Water Requirements
How long does a ROWPU last?
The ROWPU’s filters, called reverse osmosis or RO elements, are critical to desalinization and purification of water. These filters have a lifecycle of 1,000 to 2,000 operational hours. Conceivably, a ROWPU will not operate continuously or indefinitely on one set of filters. The duration of the mission will dictate down time for the ROWPU.
What type of filter does the ROWPU have?
A 50-micron self-cleaning filter and a 5-micron cartridge filter provide two-stage pre-treatment. Post-treatment is by chlorination. The ROWPU has its own generator (the unit can also be hooked up to an external power source.) The ROWPU’s filters, called reverse osmosis or RO elements, are critical to desalinization and purification of water.
How much does it cost to replace a ROWPU filter?
One 600-gallons per hour ROWPU with 8 filters and one 3,000-gallons per hour ROWPU with 12 filters, for example, have a combined filter replacement cost of $15,555.75. Projected Armywide, these filter replacement costs could adversely impact unit funds for soldier training.
