Who treats tap water in Sri Lanka?
The National Water Supply and Drainage Board runs the piped supply. It treats the water first, then tests it against safety limits. That treated water leaves the plant safe to drink. Big towns and cities get this piped supply. Some rural areas still have less coverage.
What can affect tap water quality?
Treated water can still pick up problems later. Old pipes can add rust and dirt. A cracked pipe can let dirty groundwater in. A home tank left open can grow algae. Long storage can also change the taste. So the water at your tap is not always as clean as the water at the plant.
Is well water safe to drink?
No one treats well or borehole water. Its safety depends on the local ground. Some wells stay clean. Others carry germs, hardness, or high iron. In some dry-zone areas, groundwater holds extra minerals. The World Health Organization notes that groundwater can carry natural chemicals like arsenic and fluoride. Test any well before you trust it.
How can you make your tap water safer?
Boiling kills germs in water. It does not remove dirt or chemicals. A filter takes care of the rest. A carbon filter improves taste and smell. A ceramic filter blocks dirt and germs. An RO filter removes dissolved salts. To pick one, read our guide to types of water filters. Then choose from home water filters that suit your supply.
