This report aims to identify current and expected future needs for mine water management, to describe water management procedures and decisions in different phases of a mine’s life cycle, to introduce good practices for water balance management, and present selected case study examples. Based on these, guidelines for mine water management are being created. This work is a part of the project “Management of water balance and quality in mining areas” (WaterSmart). The WaterSmart project is a part of the sustainable extractive industry program Green Mining by Tekes.
