Water reclamation and reuse systems offer a way to supplement traditional water sources by treating wastewater for various uses. To make this process successful, it's important to combine water supply and reclaimed water functions. The main challenge is the high cost of infrastructure for conventional systems, which limits their implementation in urban areas. However, alternative approaches like satellite and decentralized systems can help overcome this obstacle. The article also discusses different applications for reclaimed water, treatment technologies, and managing specific substances in the water supply.
