Cooling towers are the largest water using utility in buildings. Deteriorating water quality and decreasing sources of potable water are driving new initiatives in water conservation. Water treatment strategies that reduce potable water use and preserve resources have been successfully implemented in the past decade. The strategies presented will cover basic operational methods, treatment strategies and approaches for potable water reduction. An overview of key strategies and design criteria for architects and engineers will assist in the implementation of efficient potable water use in condenser water systems.
