Abstract: Abstract Despite the efforts to control, protect and improve freshwater resources, eutrophication is still one of the main causes for reservoir water quality deterioration. Low-quality raw water reaching water supply treatment plants (WTP) implies an increment of chemical reagents to meet safety requirements, which may also increase the potential of disinfection by-products formation. The objective of this paper was to study the relationship between raw water quality coming from a water supply reservoir and the use of reagents in the associated WTP, through a series of stepwise regression models, in order to develop a simple statistical tool to select the most adequate withdrawal depth for optimizing the treatment processes. The results showed that chlorides, ammonia and water color were the main subrogate parameters in the reservoir explaining the need of chlorine and ozone in the pre-treatment and alum sulphate consumption in the WTP. Therefore, by controlling the variation of these parameters in the water column it would be possible to select the most appropriate reservoir withdrawal depth for reducing costs and risk of by-products formation during treatment, making the most of the water purification service offered by the ecosystem.
