Consecutive Connection |
Many public water systems purchase water from
another water system. The connection to the water system that
supplies the water is called a consecutive connection.

Infiltration Gallery |
An infiltration gallery is a man-made means of
capturing water for use. In a public water system, the intended use
is human consumption. An infiltration gallery typically consists of
a perforated pipe in a gravel or sand bedding constructed along or
beneath a natural source of water (e.g., river or shallow
aquifer*). Typically, sand backfill is placed over the bedding to
improve the filtration of the natural soils in which the gallery is
constructed.

Roof Catchment |
Some places, do not have a reliable, cost
effective means of providing drinking water but do have significant
rainfall. These locations may use roof catchments to capture
rainfall to use for drinking and other purposes.

Reservoir |
In the United States Environmental Protection
Agency's drinking water program, a reservoir refers to a man-made
body of water that is used as a source of water for a public water
system (e.g., a reservoir created by a dam, a quarry, or a
sandpit). This should not be confused with a reservoir that is part
of a treatment plant to temporarily hold water as part of the
treatment process. This latter type of reservoir is considered a
storage tank by some states.

Spring |
Springs occur where the natural flow of ground
water rises to the surface and a man-made device is constructed to
capture this water.

| WL |
Well |
A well is a hole that has been drilled or bored
into the earth to withdraw water from an underground aquifer*.
