Waste water Treatment plants, sewage and water supply operation

Water treatment plants are used to produce drinking water from raw water taken from a water source. Raw water is most often surface or underground water. Water treatment is a process that changes the physical, chemical and microbiological properties of water. The higher the quality of the raw water, the simpler the treatment technology. Raw water is treated in the water treatment plant so that the product is drinking water that meets all the requirements set by legislation. Therefore, regular laboratory tests of raw water and treated drinking water are carried out in the water treatment plant.
