How is water discharged into the sea?

Most water flows through rivers. Sewage is usually treated, by digestion of the organic matter by microorganisms, followed by allowing the sludge to settle before it is discharged to rivers or the sea.

This can be done safely if a long enough pipe is used, and beaches are closed for a period after the discharge.
