Individuals who treat water and liquid waste so that it is safe to drink or remove harmful pollutants from domestic and industrial liquid waste so that it is safe to return to the environment. Water is pumped from wells, rivers, streams and reservoirs to water treatment plants where it is treated and distributed to customers. Liquid waste travels through customers' sewer pipes to liquid waste treatment plants where it is either treated and returned to streams, rivers and oceans or reused for irrigation and landscaping. Operators in both types of plants control equipment and processes that remove or destroy harmful materials, chemical compounds and microorganisms from the water. They also control the pumps, valves and other equipment that moves the water or liquid waste through the various treatment processes after which they dispose of the removed waste materials.
