Water Reclamation and Reuse: with the Emphasis on the 7th Development Plan (Planning to Access Other Waters and Recycling Industrial Water and Effluent)

Today, wastewater reclamation and reuse for different applications is considered as a suitable and economically attractive approach to deal with the main issue of water scarcity. Water reclamation includes wastewater treatment or processing in order to make it suitable for reuse with the reliability of treatment and compliance with water quality criteria. Water reuse is defined as the use of treated wastewater for useful purposes. Health and environmental concerns are primary issues in the implementation of water reuse, so the focus should be on developing approaches that provide sufficient assurance that water quality requirements are consistently met. Considering the importance of water reclamation and reuse, in this article, some methods of water reclamation, the successful experience of water reclamation in Singapore, and a proposed solution for water reclamation and reuse in our country, Iran, have been discussed.
