On June 15, 2006, President Bush has signed into law, as a National Monument, 1200 miles of islands now formerly known as the Northwestern Hawaiian Islands Coral Reef Ecosystem Reserve, making it the largest marine conservation area on Earth. For years, Lifestream Watersystems Inc.’s involvement with the area has been through the U.S. Fish and Wildlife Service in Hawaii and the hearty group of scientists that live on Tern Island, the main island of French Frigate Shoals. This island is remote—3 hours by plane or 3 days by boat in bad weather, from Hawaii. The researchers there study endangered hooded monk seals, and Hawaiian green sand turtles and monitor other wildlife. They are fully dependent on two Lifestream NDX1200 desalination systems for their fresh water.

The systems each produce 1200 gallons of potable water per day from seawater and operate off both solar power and diesel generators. For the 2-6 researchers and volunteers who live there, this has meant a much more luxurious life instead of depending on water brought by their provisioning boat that arrives only every several weeks.

The systems were designed with highly energy efficient motors to use the least amount of energy possible. Solar power was already in use on the island so the R.O. systems tied into the current solar system nicely. One system was purchased by U.S. Fish and Wildlife Service and the other system was donated by a construction company that worked on the island for a time. The great advantage of having the second system is to give a backup in case one system is down due to the need for maintenance or parts. To provide the best membrane life, U.S. Fish and Wildlife purchased an extra set of membranes and pressure vessels and then rotates a set to Lifestream for cleaning and service of the pressure vessels. They also keep a good storage of spare parts, especially fittings as their environment is unusually corrosive. Lifestream has used 316 stainless steel fittings and piping wherever possible to counter this. The residents keep in contact with U.S. Fish and Wildlife and Lifestream by email or phone for any assistance needed.

The Lifestream NDX line of systems are available from 200 to 1500 gallons/day and have found frequent application in remote locations.
