The article discusses how decentralized wastewater treatment plants can safely reuse treated water and sludge. By evaluating treatment performance, health risks, and community motivation, these plants can provide non-potable water for agriculture and reduce water contamination. Proper maintenance and community involvement are key factors in ensuring the success of these systems. With effective management, decentralized wastewater systems can meet a significant portion of clean water demand. Constraints to water reuse can be minimized through specific steps, leading to safer water and solid reuse.
