The WCA is done in three steps, a global analysis of water distribution and consumption in the network, establishing baseline minimum water targets and redesign of the water network to achieve these targets. == History == WCA was first introduced by Manan, Tan and Foo in 2004. Since then, it has been widely used as a tool for water conservation in industrial process plants. A Time dependent water cascade analysis was presented later on. A variation of the WCA is the gas cascade analysis (GCA). == References == - [[Professional Practice/Codes & Standards/National Building Code of India/Part 09 - Plumbing Services/Section 1 - Water Supply]] - [[Building Construction/Specifications and Detailing/Waterproofing Details]] - [[Digital Architecture/ePractice/GIS and Spatial Analysis]] - [[Environmental Design/Water Conservation]] - [[Research, Analysis & Citations]] - [[Research, Analysis & Citations/Checklists and Templates]] - [[Research, Analysis & Citations/Conversion Tables]] - [[Research, Analysis & Citations/Glossary]] == See also == Reclaimed water
