A low water recovery rate desalination system and method. This system and method enables the purification of water in a more environmentally sustainable manner than conventional systems. The environmental benefit of this invention is derived from its ability to desalinate water and produce a brine byproduct that is less concentrated than that of conventional desalination systems. The system is composed of three elements. They are a water makeup element, a concentration element and a desalination system. The water makeup element and the concentration element can integrated with a conventional desalination technology to form a complete desalination system.
