|(a) Water supply. For all pools and spas, the initial
fill water and make-up water used to maintain the water level and
water used as a vehicle for sanitizers or other chemicals for pump
priming or for other additions must be from a public water system,
as defined by 30 TAC §290.38 (relating to Definitions), or from
a water well that complies with the requirements of subsection (c)
of this section.
(b) Water distribution system. All portions of the
water distribution system must be protected against backflow and back
siphonage using a high hazard preventer such as a reduced-pressure-principle
backflow preventer meeting the requirements of the American Society
of Sanitary Engineering Standard 1013, as amended, and approved for
use in potable water systems possibly subjected to back siphonage
or high back pressure or an air gap designed to ASME Standard A112.1.2.
(c) Private water supply. If the water supply providing
water to the pool or spa does not meet the definition of a public
water system, as defined in subsection (a) of this section, that water
supply must comply with the following requirements.
(1) Water pressure system must be designed to:
(A) maintain a minimum pressure of 35 pounds per square
inch (psi) at all points within the distribution network at flow rates
of at least 1.5 gallons per minute per connection;
(B) maintain a minimum pressure of 20 psi under combined
fire and drinking water flow conditions when the system is intended
to provide firefighting capability; and
(C) maintain a minimum distribution pressure not less
than 20 psi at any time.
(2) Coliform testing of the well water must be performed
each month the pool or spa is open for use. Records of any bacteriological
tests must be kept on-site for three years and made available during
(3) Chemical analysis must be for the secondary constituent
levels set out by 30 TAC §290.118 (relating to Secondary Constituent
(A) Water samples for chemical analysis obtained from
the entry point to the distribution system must be submitted once
every three years to a laboratory certified by the TCEQ.
(B) Records of all chemical testing must be kept on-site
for three years and made available during inspection.
(d) Drinking water provided. At least one drinking
water fountain or other source of drinking water, such as bottled
water, must be provided and available for pool and spa users at all
pools and spas constructed on or after October 1, 1999, and must be
available at all times the pool or spa is open for use. A faucet,
spigot, or sink does not satisfy the requirements for providing drinking
water. Glass containers must not be allowed on a deck, in the pool
or spa, or anywhere within the pool yard or spa yard.
(1) The drinking water is not required to be chilled.
(2) The drinking water is not required to be in the
pool or spa yard.
(3) When the drinking water is not located in the pool
yard or spa yard, a sign with letters a minimum of 1 inch in height
is required. The sign must be posted so that it is visible to users
that informs the users of the location of the drinking water.
(e) Hose bibs. Hose bibs in the pool yard or spa yard
must be protected with a vacuum breaker.
