"Since water is a natural resource - one in limited supply - many communities are recognizing that they have to act today to ensure they'll have enough water for tomorrow. Enter water recycling, a two-step process that uses advanced technologies to turn wastewater into clean water. First, a technology called membrane filtration filters harmful solids and bacteria from wastewater through thousands of straw-like micro-porous filters. Then, the clean water passes through an even finer membrane filter. The result: water that is purified above drinking water standards."
