Abstract
In the Seventh Five-Year Plan Law, wastewater has found a special place. This issue is addressed under Article 39 and in different clauses such as clause “B” for water supply to green spaces and “C” for water supply to industries. From the perspective of water resources management, wastewater is part of a water system and an abstract view of it can be very damaging. With such a view, in any exploitation of this resource, it is first necessary to answer important questions, such as: 1) What was the previous function of wastewater in this system? 2) If the use of this resource changes, what will be the consequences on the previous function? 3) Does the exploitation of wastewater also lead to an increase in water consumption? And other questions of this type.
