Page 15-6, Sub-article 1510-3(B) Testing and Sterilization:
Add the following:
After the pipeline has been satisfactorily constructed compete with the required fire hydrants,
services, and all other appurtenances, and the trench backfilled satisfactorily, and after line flushing
and approval by the Engineer, the newly constructed pipeline and valved sections shall be
subjected to a hydrostatic pressure leakage test. The Contractor shall notify the Engineer when the
work is ready for testing with all testing done in the presence of the Engineer. All labor, equipment,
water and materials, including meters and gauges shall be furnished by the Contractor at his own
expense.
Ductile iron pipe will be tested in accordance with AWWA standards or NC DEQ requirements,
whichever is most stringent.
Each completed section of the pipeline shall be plugged at both ends and slowly filled with water.
As the main is being filed with water in preparation of the tests, all air shall be expelled from the
pipe. The main shall be subjected to hydrostatic pressure of 200 pounds per square inch for a period
of two (2) hours unless otherwise specified. Pressure shall be applied to the main by means of a
hand pump for small lines or by use of a gasoline pump or fire engine for larger lines.
The rate of leakage shall be determined at fifteen (15) minute intervals by means of volumetric
measurement of the water added during the test until the rate has stabilized at the constant value for
three (3) consecutive fifteen (15) minute periods.
Leakage is defined as the quantity of water to be supplied into the newly laid pipe, or any valved
section, necessary to maintain the specified leakage test pressure after the pipe has been filled with
water and the air expelled. No piping installation will be accepted until the leakage is less than ten
(10) gallons per inch of pipe diameter per mile of pipe per twenty-four (24) hours.
Cracked or defective pipe, joints, fittings, valves, or hydrants discovered in consequence of this
test shall be removed and replaced with sound materials, and the test shall be repeated until the
09/09/2026 4/8

UC-5A
Project: U-4700CB County: Caldwell
test results are satisfactory. Precautions shall be taken to remove or otherwise protect equipment
in, or attached to, pipe to prevent damage or injury.
Pipe interiors, fittings, and valves shall be protected from contamination. Pipe delivered for
construction shall be strung so as to minimize entrance of foreign matter. When pipe laying is not
in progress for more than one hour, all openings in the pipeline shall be closed by watertight
plugs. Joint of all pipe in the trench shall be completed before work is stopped. If water
accumulates in the trench, the plug shall remain in place until the trench is dry.
If dirt enters the pipe that, in the opinion of the Engineer, will not be removed by flushing
operations, the interior of the pipe shall be cleaned and swabbed as necessary, with a 5%
hypochlorite disinfecting solution.
Sampling taps may be used as blow-offs. The number and locations of the taps/blow-offs must be
approved by the Engineer. Hydrants may not be used for bacterial sampling.
The Contractor shall construct taps so that bacteriological samples can be easily collected without
danger to personnel or likelihood of sample contamination. The Contractor shall legibly mark
each sample tap with identifying letters or numbers for sample reference purposes. The
Contractor shall not designate hydrants as taps for bacteriological sampling purposes. If the
service or corporation taps are installed before the laboratory tests are completed, each tap will be
tested for coliform bacterial.
Before being placed in service, all new mains and existing piping disturbed in any manner by the
work shall be disinfected. Draining the water from existing piping or even lowering the water
pressure more than one-half will constitute disturbance of the piping.
The disinfecting of water mains, valves and other appurtenances incorporated into the main
construction shall be done by means of a chlorinating measuring apparatus, with proper devices
for regulating the flow and providing an effective diffusion into the water within the main being
disinfected by an application of chlorine-bearing compound bearing a high-test calcium
hypochlorite (65-70%) available chlorine). In the preparation of the solution, the powder shall
first be made into a paste and then gradually thinned with water to approximately 1% chlorine
solution (10,000 parts per pound of powder). This will require about 7.50 gallons of water to each
one pound of powder. Solution shall be applied to the main through a rubber hose by gravity,
siphonage, injection or by suitable pump feeder.
The point of chlorine application shall be at the beginning of the water main construction and/or
any valve section thereof, through corporation cock installed close to and on the downstream side
of the regulating gate valve controlling the flow of such proportion to the rate of water flow
entering the main that the chlorine applied shall produce fifty (50) parts per million (420 pounds
per million gallons) chlorine concentration in the water within the main.
During the disinfecting operation, valves, hydrants, and other mechanical devices controlling the
flow of water shall be operated to permit full effectiveness of the chlorine. Valves shall be
manipulated so that the strong solution within the main being sterilized will not flow back into the

Project: U-4700CB County: Caldwell
supply line nor flow into mains already in service. A chlorine concentration test shall be made, in
turn, at each of the hydrants and/or taps provided for that purpose.
The tablet method of disinfection may be utilized for disinfection provided the total length of
potable water main to be laid is less than 2,000 linear feet of pipe less than 12" in diameter. This
method will be suitable only, if in the opinion of the Engineer, the pipeline has been maintained
suitable free from foreign matter and any other contaminants during construction.
The Contractor shall provide sampling taps, Generally, sampling taps shall be provided on the
water main every 1,000' and at the end of each main and at the end of each branch, in order to
afford representative water testing and sample collection.
All disinfection shall be performed in accordance with AWWA Standard C651 and the Rules
Governing Public Water Systems. All bacteriological tests shall be performed by a state-approved,
certified laboratory per Rule .1001.

The maximum allowable limits for deflection of installed pipe under this specification shall be 7.5%.
Base inside diameters and 7.5% deflection mandrel dimensions shall be per ASTM F-679 (latest
edition). Deflection shall be measured with a rigid mandrel (Go/No Go) device cylindrical in shape
and constructed with a minimum of nine evenly spaced arms or prongs. Drawings of the mandrel
with complete dimensions shall be submitted to the Engineer for each diameter of pipe to be tested.
The mandrel shall be hand pulled through all sewer lines.
Any section of sewer not passing the mandrel shall be uncovered and the bedding and backfill replaced
to prevent excessive deflection. Repaired pipe shall be retested to ensure that acceptable deflection limits
are not exceeded.
