Abstract: Design and management of infiltration systems should be adapted to local conditions of water quality, climate, soil, hydrogeology, and environmental constraints. Aspects to be considered include water depth, lengths of flooding and drying periods, frequency of cleaning basins, pre-sedimentation, and a choice between infiltration basins with essentially stagnant water where even the finest suspended particles can settle on the bottom, and infiltration channels with flowing water where the fine particles are kept suspended because of turbulence. Water quality considerations include chemical and biological parameters of the influent water, changes in water quality as the water moves through the vadose zone and aquifer, and potential leaching of trace elements from the vadose zone.
