Many innovative water conservation and reuse techniques are currently available and have proven highly effective for not only conserving water, but also reducing waste, and saving money. Identi$ing these options is a key concern for today’s environmental and process engineer as they can simplify regulatory requirements, reduce disposal and tieatment costs, and conserve raw materials. This paper approaches water conservation technologies from a process perspective. A general process analysis approach is presented, followed by specitic case studies ffom businesses in Texas and the border states of Mexico, Simple water conservation methods, such as the use of spring loaded or solenoid shut-off valves are discussed, as well as more advanced techniques such as automated process control, process water reuse, and rain water collection. In addition, methods to conserve water in cleaning and decreasing, electroplating, and coating operations are presented.
