Issues and guidelines for treated wastewater reservoirs design and operation

Abstract: The potential wastewater stabilisation during the storage phase might improve significantly water quality therefore making appropriate to use this hydraulic component also as part of the treatment line of a reuse system. An experimental research was carried out in a small farm reservoir, receiving treated wastewater, aimed at investigating design and management parameters (depth, surface/volume ratio, incoming/outcoming flows), and role of operational indexes, like MRT (mean retention time) and PFE_n (percentage of fresh effluents). Guidelines for proper design and operation were developed aiming at achieving higher removal efficiency and a more homogeneous quality of the reservoir effluent during the irrigation season. A mass balance model was developed and a simulation was carried out to verify the effectiveness of the proposed management criteria by calculating corresponding MRTs and PFE_n.
