A water supply system pumps, distributes, and treats water.

A well is a hole, usually drilled about 500 feet. It allows access to groundwater from pumping.

Water can either be treated at a central location or treated as it enters the home.

A storage reservoir stores backup water. It is used to ensure a constant supply of water even at peak times.

Gravity pulls water from the reservoir to homes. For this reason, it must be placed at a higher elevation than homes.

Rainwater collection can be used to supplement water supply. It requires additional treatment for bacteria and microbes.
