WATER DISTRIBUTION EXAM
REVIEW TESTED QUESTIONS
ACCURATE SOLUTIONS
◉ E.P.A. Answer: Environmental Protection Agency
◉ T.D.S. Answer: Total Dissolved Solids (mg/L)
◉ C.C.R. Answer: Consumer confidence report
◉ A.R.V. Answer: Air Relief Valve
◉ S.O.P. Answer: Standard Operating Procedure
◉ Micro Answer: small
◉ Macro Answer: Can see with your naked eye
◉ Aerobic Answer: Dissolved Oxygen
◉ Anaerobic Answer: without oxygen
,◉ U.F.W. Answer: Unaccounted For Water
(Allowed 10%-20% water loss)
◉ C.U.P. Answer: Consumptive Use Permit
◉ T.D.H. Answer: Total Dynamic Head
◉ D.C.D.A Answer: Double Check Detector Assembly
◉ What the Universal Solvent? Answer: Water
◉ Static Answer: Stop
◉ Dynamic Answer: Moving
◉ S.C.B.A Answer: Self Contained Breathing Apparatus
◉ C.I.P Answer: Capital Improvement Program
◉ M.S.D.S. Answer: Material Safety Data Sheet
(16 Sections)
,◉ Interface Answer: A common boundary where different parts of a
system interact.
(Water and Soil)
◉ Sanitary Survey Answer: A detailed evaluation or inspection of a
source of water supply and all conveyances, storage, treatment, and
distribution facilities to ensure protection of the water supply from
all pollution sources.
◉ Friction loss Answer: Loss of pressure created by the turbulence
of water moving against the interior walls of fire hose, pipes, fittings,
and adapters.
◉ Electrical Reaction Answer: Chemical changes produced by
electricity. (Galvanic Action)
◉ After Growth Answer: Disinfectant by product left by chlorine
◉ Ventri Meter Answer: A venturimeter is a device used to measure
the fluid flow through pipes. This difference in pressure is measured
with the help of a manometer and helps in determining rate of fluid
flow or other discharge from the pipe line.
, ◉ Hydraulic Grade Line (H.G.L.) Answer: If a pipe is under pressure,
thehydraulic grade line is that level water would rise to in a small,
vertical tube connected to the pipe.
◉ Residual Chlorine Answer: The concentration of chlorine present
in water after the chlorine demand has been satisfied.
◉ As water ___________ increases, water____________ decreases.
(Friction Loss) Answer: Velocity Pressure
◉ What is the most commonly use disinfectant in distribution
systems? Answer: Free Chlorine
◉ What does chlorine and ammonia make? Answer: Chloramines
◉ Chloramines Answer: A dosage of 3 parts of chlorine to 1 part
ammonia will form Monochloramines.
◉ If using Combined Chlorine and Chloramines (Monochloramines),
what does it need to be in the distribution system? Answer: 1.2
leaving the plant
0.6 at the farthest point
