WATER SUPPLY SYSTEMS EVALUATION EXAM 2026
QUESTIONS AND SOLUTIONS RATED A+
✔✔Super Heated - ✔✔______ water is water under pressure that is heated above 212
degrees F without becoming steam.
✔✔Iron Pipe Size - ✔✔Schedule pipe is ______ with an outside diameter and a wall
thickness that matches the wall of the same size and schedule as steel pipe.
✔✔Sliplining - ✔✔______ is a restoration process that involves accessing the
deteriorated water distribution line at strategic points within the system and inserting
polyethylene pipe lengths, joined into a continuous tube, throughout the existing pipe
structure.
✔✔Freeze Line - ✔✔Trench depth should be below the local _____
✔✔Cable tool - ✔✔______ drilling, also known as percussion or hammer drilling, is the
rhythmic raising and lowering of a heavy drill string cable with a bit on the end that
breaks up the earth material by slightly rotating each time it is lifted and dropped.
✔✔Percipitation - ✔✔Atmospheric water vapor becomes concentrated in cloud
formations and, being heavier than air, falls to the earth as ________.
✔✔Storage Flood Control - ✔✔An impounding reservoir has two functions: impounding
surface water for beneficial use and ______
✔✔Storage - ✔✔The ______ system component of a rainwater catchment system
consists of cisterns or tanks, filtering or other treatment systems, pumps, and controls.
✔✔private individuals - ✔✔A privately owned public water system is a public water
system that is owned and operated by ______.
✔✔Turbidity - ✔✔______ level is the measure of cloudiness in water and is measures
by shining a light through the water.
✔✔Storm Water Catchment - ✔✔A(n) ______ system collects and stores storm water,
and it consists of a cistern, pipe, fitting, pumps, and/or other plumbing appurtenances.
✔✔Intake Works - ✔✔______ are the structures used to divert or pump raw water from
freshwater sources or impounded reservoirs to treatment facilities.
✔✔Desalination - ✔✔______ is the process of removing salt and other minerals from
ocean or other saline water
, ✔✔Reclaimed Water - ✔✔An alternate water source is a nonpotable source of water
that inlcudes, but is not limited to,________, black water, grey water, storm water, and
rainwater.
✔✔Topography - ✔✔The ______ of the area is the greatest factor in determining
whether pumped pressure is needed to deliver water to each water service.
✔✔Dead End - ✔✔The four basic types of piping networks are the _______, radial, grid,
and looping piping networks.
✔✔Sedimentation - ✔✔Outlet piping with screening should be installed above the floor
line to prevent any ______ that may occur as water is transported out of a tank.
✔✔Shoe - ✔✔The ______ is the base of the hydrant, connects to the lower barrel, and
contains the main operating valve, drain valve, and connection to the water distribution
branch pipe.
✔✔Post - ✔✔A(n)______ -type hydrant is a special-purpose hydrant for use in which
firefighting is not the primary purpose of the hydrant.
✔✔At Night - ✔✔To offset power use and water demand times, water storage areas
should be filled ______.
✔✔angle of repose - ✔✔The______ is the greatest angle above the horizontal plane at
which material will lie without sliding back into the trench.
✔✔Indirectly - ✔✔In a combination gravity and forced-feed system, water is ______
pumped into the water distribution system.
✔✔Indicator Post - ✔✔A(n)______ is a device attached to a gate valve that provides a
means to operate a buried gate and indicates whether the valve is closed or open.
✔✔Horizontal - ✔✔Double-check backflow prevention assemblies are usually tested
and approved for _______ installations.
✔✔Effective - ✔✔The ______ opening is the minimum cross-sectional area at the point
of water supply discharge measured or expressed in terms of diameter or, if the opening
is not circular, the diameter of a circle of equivalent cross-sectional area.
✔✔Backsiphonage - ✔✔______ backflow is backflow condition in which used,
contaminated, or polluted water from a plumbing fixture or vessel flows back into a
water supply pipe due to pressure being less than atmospheric pressure piping.
