This presentation reviews southern Arizona's water flow path from source to use in electric energy generation and air conditioning heat rejection to reclamation and disposal. Two current examples of municipal scale reclamation and reuse of treated effluent in evaporation in electric generation and air conditioning are described. Water conservation technologies applicable to District Cooling Systems in the southwest US are outlined and discussed in the context of current costs, rate structures and triggers.
