Water quality analysts are responsible for the purification of water by removing harmful household and industrial substances from the water. They assist in operating water works for drinking water, wastewater and/or industrial effluent.

Water quality analysts check the quality of water through scientific analysis, ensuring quality and safety standards are met based on the water quality index, for its use as: drinking water, agricultural water, wastewater and/or industrial effluent. They take samples of the water and conduct analysis of this in a laboratory, and develop purification and treatment procedures. 

Water treatment or water purification is the process of removing harmful household and industrial substances from the water. Waste water is transported by drainpipes from houses and industries to water purification works. At purification works, water quality analysts manipulate pumps, valves and other equipment to extract impurities from the water. They interpret readings on the meters to ensure a smooth-running process and control the addition of chemicals to purify the water. They then take samples of the water to be analysed in the laboratory. Water quality analysts may be involved in laboratory duties such as analysis of water samples, as well as research and the development of new, improved unit operations in water care technology.

Water quality analysts supervise the workers responsible for maintaining the plant with respect to the repairing pumps and valves and cleaning the tanks and canals.
