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.

IN |
Intake |
A man-made device for extracting raw (i.e., untreated)
water from a river or lake or other "surface water" source.

NP |
Non-Piped |
A non-piped source of water typically refers to
water that has been transported to a facility via a sanitary tanker.

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.

RS |
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.

SP |
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*.
