Water quality
improvement entails the disinfection and purification of untreated ground and
surface water.
At the Community Level
The purpose of a public or private water
treatment facility is to make water potable (safe to drink) and palatable
(pleasant to taste) while also ensuring that there is a sufficient supply of
water to meet the community’s needs.
Raw and untreated water is obtained from an
underground aquifer (usually through wells) or from a surface
water source, such as a lake or river.
It is pumped, or flows, to a treatment facility.
Once there, the water is pre-treated to remove debris such
as leaves and silt.
Then, a sequence of treatment processes — including
filtration and disinfection with chemicals or physical processes —
eliminates disease-causing microorganisms.
When the treatment is complete, water flows out into the
community through a network of pipes and pumps that are commonly referred
to as the distribution system.
Public vs. Private
What’s the difference between public and private
water treatment facilities?
Public, municipal systems are owned and operated by the
cities or towns they serve, and they’re typically under the management of
a mayor or other elected official.
Private systems range from individual wells serving a
single household, to small corporate associations that provide water to a
small group of homes, or to large corporations that have their
own water service divisions.
Whether public or private, all U.S. water utilities that
serve more than 25 people must adhere to water quality standards established by the U.S. Environmental
Protection Agency (EPA) as well as state and local
regulations.
Point-of-Use and Point-of-Entry
Treatment
Point-of-Use (POU) devices treat water at the point of
consumption.
The technology provides the final barrier to the contaminants of
concern before the water is consumed or used.
Some commonly used technologies include:
· Activated Carbon
· Reverse Osmosis
· Ultraviolet (UV) Technologies
· Distillation
Point-of-Entry (POE) devices are whole-house treatment systems
mainly designed to reduce contaminants in water intended for showering, washing
dishes and clothes, brushing teeth, and flushing toilets.
· Ion Exchange
· Activated Carbon
· Filtration
WQA primarily represents
the sector of the water treatment industry devoted to treating water on the
homeowner's or business-owner's property.
We often refer to this aspect of treatment as
the Final Barrier that prevents waterborne contaminants from entering a home or
business.
Whether
your water arrives from a community treatment plant, municipal well or other
source, WQA's member companies are committed to making that water safe and
aesthetically pleasing for those who consume or use it.
WQA
is a resource and information source, a voice for the industry, an educator of
professionals, and laboratory for product testing.
