You can’t use seawater to drink or sprinkle plants. A process called desalination allows you to obtain fresh water from oceans. People in cities get water from reservoirs, storage areas for fresh water. This water is transported by pipelines to locations where it’s needed. Some people tap into groundwater by digging wells. These holes are dug beneath the water table. Other holes are dug into aquafers sandwiched between rock layers. Some groundwater seeps out in a place called a(n) spring.
