Water reclamation is the process of treating wastewater to make it usable again for non-potable purposes. Some synonyms for water reclamation include wastewater treatment, greywater recycling, and sewage reuse. The objective of this process is to reduce the demand for freshwater and to improve water sustainability by reusing treated water rather than discharging it into waterways. Water reclamation systems typically involve physical, biological, and chemical treatment processes to remove contaminants from wastewater. The treated water can then be used for irrigation, industrial processes, or toilet flushing. The use of water reclamation systems is becoming increasingly important as water scarcity becomes a growing issue around the world.
