Proper water supply for human or inhuman use includes a series of processes that varies according to the type of consumption, structure and nature. This chain should be seen together and studied. Failure to analyze any of these sections can create problems for humans or the environment. Therefore, comprehensive studies of water supply to the consumer (human or non-human) are inevitable and the evaluation of various technical, economic, environmental and health impacts, in addition to creating sustainable water supply conditions, reduces the risks and costs associated with the project.
Generally, the water supply chain can be defined as follows:
Today, the environmental and health problems of unsustainable sewage disposal are not overlooked. On the other hand, water resource constraints have resulted in water recycling and reuse of waste water in the water industry. Different methods of collecting and disposing of sewage and reuse of wastewater are necessary to make studies in this section very necessary. The implementation of technical, economic, environmental and health studies and the use of decision-making models with multivariate and multi-objective criteria has provided a more reliable and efficient outcome. There will also be a chain of facilities for waste disposal or reuse of wastewater, which will be as follows.
