Abstract: System and methods for water management method for managing water used in extraction of fluids from subsurface formations wherein water is stored in a plurality of water pits and further wherein water is obtained from one or more water wells. The method includes simulating water pit volumes to determine a water level in each of the water pits at a pit volume simulation time; performing water chemistry analysis to determine one or more chemical properties of water stored in one of the water pits; performing a mapping operation to determine one or more pipeline routes, pit-pit transfer lines, and gathering systems; performing water pit evaporation analysis for a water pit evaporation simulation time; and performing a cost data capture to determine forecast costs at a cost data capture simulation time.
