to preserve a particular type of habitat and its flora and fauna, which are often rare or endangered.

Talk in table groups,Have you ever been to an ecological preserve? Where?

Why are ecological preserves important?

Natural FiltrationThe CRW is one of the largest watersheds in the

country that naturally filters its water.

A lot of watersheds that are used as drinking water sources need specially fabricated filtration systems.With chemicals at filtration plants.

Talk in table groups,What’s raw water?

Normal drinking water filtration systems

ReservoirsReservoirs are used

to store water, usually drinking water.

Created by dams.

Water routed to cities by pipelines.
