Best Answer

A dam is simply an edifice that stores water; and few dams have purification facilities. They may have rudimentary filters to prevent damage to sluices and hydro-electric turbines.

Purification is done by multi-stage filtering, plus the addition of chemicals such as chlorine (to kill bacteria) and fluorine 9in drinking water, to maintain healthy teath).
