20- and 40-Foot Containers
Our water box system operates with 100% success rate

Complete Water Systems 20- and 40-foot units provides up to 50,000 and 144,000 gallons or 189,200 and 545,000 litres of water per day respectively for direct delivery to nearby homes, farms, hotels or construction projects.
Each unit can purify water based on three specific needs:
-
potable (drinking) water
-
household and commercial
-
agricultural
Our units can turn seawater, brackish, pond, lake or river water into clean, pure, safe drinking water that is better than World Health Organization standards. Our seawater desalination plants use the latest and most energy efficient reverse osmosis and distillation systems. You have a choice of single- or double-pass reverse osmosis system.
​
CWS makes potable water production easy to handle, affordable and accessible anywhere on the globe. Combined with the low maintenance costs and record low energy consumption feature, the reverse osmosis membrane is of the best quality available in the industry.
The construction of the membrane is a thin film composite (TFC). This is the only reverse osmosis membrane that is approved by the United States Food & Drug Administration (FDA).
Everything you need is all there in the container, ready to produce high-quality potable water within days of delivery. Even the energy necessary to power all of the system is built right into the container in a sound-dampened environment. All that is necessary is to have access to the water source that needs to be purified and a place to unload the container(s).
