The water industry is essential to the population especially in residential, commercial, and industrial sectors by providing drinking water and wastewater treatment services. Water treatment plants and water towers collect, treat and deliver water to end users such as households, industrial and agricultural users. Sewers and waste water treatment plants collect, remove and treat wastewater and sewage.

Water use has been growing substantially in recent decades. It is estimated that the global annual growth of the water infrastructure market is 5-6%, while a lot of existing water infrastructure is being renovated to extend its service life.
