(63) Plumbing inspector--Any person employed by a political
subdivision for the purpose of inspecting plumbing work and installations
in connection with health and safety laws and ordinances, who has
no financial or advisory interest in any plumbing company, and who
has successfully fulfilled the examinations and requirements of the
Texas State Board of Plumbing Examiners.
(64) Plumbing ordinance--A set of rules governing plumbing
practices which is at least as stringent and comprehensive as one
of the following nationally recognized codes:
(A) the International Plumbing Code; or
(B) the Uniform Plumbing Code.
(65) Potable water customer service line--The sections
of potable water pipe between the customer's meter and the customer's
point of use.
(66) Potable water main--A pipe or enclosed constructed
conveyance operated by a public water system which is used for the
transmission or distribution of drinking water to a potable water
service line.
(67) Potable water service line--The section of pipe
between the potable water main and the customer's side of the water
meter. In cases where no customer water meter exists, it is the section
of pipe that is under the ownership and control of the public water
system.
(68) Potential contamination hazard--A condition which,
by its location, piping or configuration, has a reasonable probability
of being used incorrectly, through carelessness, ignorance, or negligence,
to create or cause to be created a backflow condition by which contamination
can be introduced into the water supply. Examples of potential contamination
hazards are:
(A) bypass arrangements;
(B) jumper connections;
(C) removable sections or spools; and
(D) swivel or changeover assemblies.
(69) Process control duties--Activities that directly
affect the potability of public drinking water, including: making
decisions regarding the day-to-day operations and maintenance of public
water system production and distribution; maintaining system pressures;
determining the adequacy of disinfection and disinfection procedures;
taking routine microbiological samples; taking chlorine residuals
and microbiological samples after repairs or installation of lines
or appurtenances; and operating chemical feed systems, filtration,
disinfection, or pressure maintenance equipment; or performing other
duties approved by the executive director.
(70) psi--Pounds per square inch.
(71) Public drinking water program--Agency staff designated
by the executive director to administer the Safe Drinking Water Act
and state statutes related to the regulation of public drinking water.
Any report required to be submitted in this chapter to the executive
director must be submitted to the Texas Commission on Environmental
Quality, Water Supply Division, MC 155, P.O. Box 13087, Austin, Texas
78711-3087.
(72) Public health engineering practices--Requirements
in this chapter or guidelines promulgated by the executive director.
(73) Public water system--A system for the provision
to the public of water for human consumption through pipes or other
constructed conveyances, which includes all uses described under the
definition for drinking water. Such a system must have at least 15
service connections or serve at least 25 individuals at least 60 days
out of the year. This term includes: any collection, treatment, storage,
and distribution facilities under the control of the operator of such
system and used primarily in connection with such system, and any
collection or pretreatment storage facilities not under such control
which are used primarily in connection with such system. Two or more
systems with each having a potential to serve less than 15 connections
or less than 25 individuals but owned by the same person, firm, or
corporation and located on adjacent land will be considered a public
water system when the total potential service connections in the combined
systems are 15 or greater or if the total number of individuals served
by the combined systems total 25 or greater at least 60 days out of
the year. Without excluding other meanings of the terms "individual"
or "served," an individual shall be deemed to be served by a water
system if he lives in, uses as his place of employment, or works in
a place to which drinking water is supplied from the system.
(74) Quality Control Release Value (QCRV)--A minimum
quality standard of a non-destructive performance test established
by the manufacturer for membrane module production that ensures that
the module will attain the targeted log removal value demonstrated
during challenge testing.
(75) Reactor Validation Testing--A process by which
a full-scale ultraviolet (UV) reactor's disinfection performance is
determined relative to operating parameters that can be monitored.
These parameters include flow rate, UV intensity as measured by a
UV sensor and the UV lamp status.
(76) Resolution--The size of the smallest integrity
breach that contributes to a response from a direct integrity test
in membranes used to treat surface water or groundwater under the
direct influence of surface water.
(77) Sanitary control easement--A legally binding document
securing all land, within 150 feet of a public water supply well location,
from pollution hazards. This document must fully describe the location
of the well and surrounding lands and must be filed in the county
records to be legally binding. For an example, see commission Form
20698.
(78) Sanitary survey--An onsite review of a public
water system's adequacy for producing and distributing safe drinking
water by evaluating the following elements: water source; treatment;
distribution system; finished water storage; pump, pump facilities,
and controls; monitoring, reporting, and data verification; system
management, operation and maintenance; and operator compliance.
(79) Sensitivity--The maximum log removal value (LRV)
that can be reliably verified by a direct integrity test in membranes
used to treat surface water or groundwater under the direct influence
of surface water; also applies to some continuous indirect integrity
monitoring methods.
(80) Service line--A pipe connecting the utility service
provider's main and the water meter, or for wastewater, connecting
the main and the point at which the customer's service line is connected,
generally at the customer's property line.
(81) Service pump--Any pump that takes treated water
from storage and discharges to the distribution system.
(82) Significant deficiency--Significant deficiencies
cause, or have the potential to cause, the introduction of contamination
into water delivered to customers. This may include defects in design,
operation, or maintenance of the source, treatment, storage, or distribution
systems.
(83) Stage--In reference to a reverse osmosis or nanofiltration
membrane system, a set of pressure vessels installed in parallel.
(84) System--Public water system as defined in this
section unless otherwise modified (i.e., distribution system).
(85) Transfer pump--Any pump which conveys water from
one point to another within the treatment process or which conveys
water to storage facilities prior to distribution.
(86) Transient, noncommunity water system--A public
water system that is not a community water system and serves at least
25 persons at least 60 days out of the year, yet by its characteristics,
does not meet the definition of a nontransient, noncommunity water
system.
(87) Vessel--In reference to a reverse osmosis or nanofiltration
membrane system, a cylindrical housing unit where membrane modules
are placed in a series to form one unit.
(88) Wastewater lateral--Any pipe or constructed conveyance
carrying wastewater, running laterally down a street, alley, or easement,
and receiving flow only from the abutting properties.
(89) Wastewater main--Any pipe or constructed conveyance
which receives flow from one or more wastewater laterals.
