In San Juan, Argentina, one of the main industrial activities is the wine production. Wineries use large quantities of fresh water for cleaning tasks especially during the wine vintage. This study presents two parts: the design of the water and wastewater network. These proposals have been carried out in a winery of San Juan, Argentina. The results proved that a water reduction of 30 % can be achieved, approximately. The second part of this work attempts to demonstrate that a distributed effluent treatment network leads to reduction of the effluent flowrate to be treated in order to fulfill the permitted contaminant level for discharging in the sewage or a natural water course. The present work combines this technology with an equation system that leads to design a distributed effluent treatment network for batch processes. The obtained network reduces the global treatment flowrate by collecting streams in different groups according to their contaminant concentrations and processing them separately.
