As with most other aspects
of environmental permitting, there have been many changes to the permitting of
potable water supply systems over the years.
Often, water supply and
wastewater disposal go hand in hand. The majority of water supplies are
classified as Non Public systems (even systems that actually do serve the
public). Permitting for these systems falls under the state Wastewater
There are other types of
water systems that fall under the jurisdiction of the Water Supply Division. In
general, these are:
Community Water System (PCWS)
PCWS’s generally serve
year round users. An example of a PCWS is a large residential subdivision where
everyone shares one common source of water. For someone who is served by a
PCWS, it is likely his or her main source of potable water. As such, PCWS’s are
afforded the highest protection.
An NTNC system is a slight
step down from a PCWS. This type of system serves more than 25 or more of the
same people for more than 180 days per year. Examples include schools and
Non-Community Water systems (TNC)
A TNC is a system that
serves more than 25 people more than 60 days per year, but is not a PCWS or an
NTNC. Examples include restaurants and motels.
PCWS, NTNC, and TNC systems, a permit is typically required from the Water
Division. For Non-Public
systems, a permit is required from the Wastewater Management Division. In many
cases, permits are required from both agencies.
