The present study aims to evaluate the wastewater management system in AlQurayyat, with primary focus on the efficacy of the treatment plant that was operated 30 years ago. One of the objectives of the study is to throw light on the environmental consequences of wastewater and suggest innovative, novel solutions to this problem. Approximately 4000000 m3 of wastewater comes from localities served by the sewerage system every year. About 6000000 m3 of the total wastewater comes from the localities lacking any sewerage system services. About 20% of the wastewater discharges from such localities is transferred by truck tankers and dumped directly into open fields nearby Kaf village. Approximately 95% of the total existing waste flow is treated by a single treatment plant acquiring a capacity of 300 m3/hour (8500 m3/day). The raw sewage arriving to the plant varies markedly according to the human consumption and seasonal rainfall. A mean value of 900 m3/hour was recorded during January 2015. In 2014, more than 5000000 cubic meters of the wastewater were dumped either into a man-made pond or an open field nearby Kaf village, 15 Km northern AlQurayyat. Successful and sustainable management of wastewater requires a composite of innovative projects, for example innovative financing of appropriate wastewater infrastructure (design, construction, operation, maintenance, and upgrading). Thinking to the long-term and creating solutions for smart wastewater management in the light of rapid global change is strongly recommended. Strategic planning in the water sector must be appropriate at the social, cultural, economic and environmental scales.
