Answer 1

Answer:

HOPE IT HELPS!

Explanation:

Many dammed river reservoirs and most bank-side reservoirs are used to provide the raw water feed to a water treatment plant which delivers drinking water through water mains. The reservoir does not merely hold water until it is needed: it can also be the first part of the water treatment process.

Answer 2

Answer:

Reservoirs hold very large quantities of water because :

• The amount of water in a river varies over time.

• During very rainy times or when mountain snow is melting, the water in a river rises and sometimes overflows its banks.

•By limiting the amount of water allowed to continue downriver, reservoirs help control flooding.
