How does water supply and sanitation use water ? (1 of 5)
water supply and sanitation sector has two main categories of water
users: domestic; and industrial/commercial.
water users need dependable supplies of “safe” water
...for drinking, cooking, bathing, washing and basic household cleaning.
They also have to dispose of human waste and washwater in ways which
do not create health risks or environmental damage.
Industrial users frequently need large quantities of water for cooling
and other processes
Their residual water is returned, often in contaminated form to
water courses. Some industries (chemicals, fertilisers, coffee processing,
…) produce highly toxic or biologically polluting effluents.
