(18) Cross-connection control device--A device that
is designed to prevent a physical connection between a potable water
system and a non-potable source such as the lagoon, or a physical
connection between the lagoon and a sanitary sewer or wastewater disposal
system. (See paragraph (12) of this section "Backflow prevention device.")

of frictional resistance of a surface one pushes against when already
in motion.

resistance or DCOF of a tile surface under known conditions using
a standardized sensor prepared according to a specific protocol.
(21) Deck--An area immediately adjacent to or attached
to the lagoon that is specifically constructed or installed for sitting,
standing, or walking and may include the coping. The term does not
include a sandy beach area adjacent to a zero-entry access area.
(22) Deep area--A water level in the lagoon that is
over five feet in depth.
(23) Department--The Texas Department of State Health
Services.
(24) Depth--Vertical distance measured at three feet
from the lagoon wall or barrier from the bottom of the lagoon to the

range of the skimmers.
(B) For a gutter or overflow system, the top of the
overflow rim of the gutter or overflow system.
(26) Disinfectant--Energy, chemicals, or a combination
of both used to kill undesirable or pathogenic (disease causing) organisms
and having a measurable residual or level adequate to make the desired
kill.
(27) Diving board--A recreational mechanism for entering
the lagoon, consisting of a semi-rigid board that derives its elasticity
through the use of a fulcrum mounted below the board.
(28) DPD--A chemical testing reagent (N, N-Diethyl-P-Phenylenediamine).
It is used to measure the levels of free chlorine or bromine in water
by yielding a series of colors ranging from light pink to dark red.
(29) Facility--The lagoon and restrooms, dressing rooms,
equipment rooms, decks or walkways, beach entries, enclosure and other
appurtenances directly serving the lagoon.
(30) Filter--A device that removes undissolved particles
from water by recirculating the water through a porous substance (filter
media or element).
(31) Filter media--A finely graded material (for example,
sand, diatomaceous earth, polyester fabric, or anthracite) that removes
filterable particles from the water.
(32) FINA--Fédération Internationale
de Natation. The organization that administers international competition
