2. TESTING - SANITARY SEWERS AND APPURTENANCES
2.2 Air Test Method
The sewer pipe section under test shall be clean at the time of testing, but the pipe may be wetted.
Pneumatic balls shall be used to plug the pipe ends at manholes. Low pressure air shall be introduced
into the plugged line until the internal air pressure reaches 4.0 psi greater than the average back
pressure of any ground water pressure that may submerge the pipe. At least 2 minutes shall be allowed
for the air temperature to stabilize before readings are taken and the timing started. During this time,
the Contractor shall check all plugs with soap solution to detect plug leakage. If plugs are found to leak,
air shall be bled off, the plugs shall be retightened, and the air shall be reintroduced into the line.
The sewer section under test will be accepted as having passed the air leakage test if it does not loose
air at a rate to cause the pressure to drop from 3.6 to 3.0 psi in less time than 112 minute per inch in
diameter of the pipe tested.
Test Failure and Remedy:
I. In the event of test failure on any test section, testing shall be continued until all leakage has
been detected and corrected to meet the requirements. All repair work shall be subject to
acceptance of the Engineer. Introduction of sealant substances by means of the test water will
not be permitted.
2. Unsatisfactory repairs or test results may result in an order to remove and replace pipe as the
Engineer considers necessary for test conformance. All repair and replacement work shall be at
the Contractor's expense.
2.1 Exfiltration Test
All sanitary sewer lines, including service connections, shall be substantially watertight and tested for
excessive leakage upon completion and before connections are made to the service by others. Each test
section of the sewer shall be subjected to exfiltration testing, either by hydrostatic or air test method
as described below. The requirements set forth for maximum leakage shall be met as a condition for
acceptance of the sewer section represented by the test.
If the ground water level is greater than 3 feet above the invert elevation of the upper manhole and the

1. FIRE HYDRANT AND WATER MAIN VALVE OPERATION
Only authorized City personnel will operate fire hydrants and water main valves. This means
that a Contractor will not use a fire hydrant for construction water or for flushing water and
sewer mains unless a valid permit has been issued. Contractors will not operate water main
valves in the existing water system unless a valid permit has been issued. A permit for
operating valves will only be issued when there is no chance of interrupting or contaminating
the existing water system.
A permit may be issued for this purpose when Water Department personnel are not available
for valve operation, but only after a 24 hour notice has been given.
Before valves will be operated or a new water main can be filled for testing or flushing, a 24
hour notice must be given to the City Water Department.
If it becomes necessary to interrupt water service because of new utility construction, 72 hour
advance notice must be given to the City Water Department so that written notice may be
given to the affected customers prior to interruption of service. When notified, the City Water
Department will take the responsibility for customer notification.

minutes. Current flow through the pipe shall be measured continuously on a suitable ammeter
and shall remain steady without interruption or excessive fluctuation throughout the5 minute
test period.
Insufficient current or intermittent current or arcing, indicated by large fluctuation of the
ammeter needle, shall be evidence of defective electrical contact in the pipeline. The cause
shall be isolated and corrected. Thereafter, the section in which the defective test occurred
shall be retested as a unit and shall meet the requirements.

Sources of D.C. current for these tests may be motor generators, batteries, arc welding
machines, etc.; D.C. arc welding machines will probably be the usual source. These machines
are available in adequate capacity for these tests and are equipped with controls for regulating
the current output.
Cables from the power source to the section of the system under test should be of sufficient
size to carry the test current without overheating or excessive voltagedrop. Usable sizes will
probably be in the range of 2/0 to 4/0 AW.G.
Connections for the test shall be made at hydrants. The hydrants shall be in the open position
with the caps on during the test. The cable shall be clamped to the top operating nut. Note:
After the test, the hydrant shall be shut off and a cap loosened to allow hydrant drainage.
Tighten cap after drainage.
A hook-on type D.C. ammeter placed on one of the cables leading to the hydrant is a
convenient method of measuring current.
In using arc welding machines, the current control should be set at a minimum before starting.
After starting the machine, advance the control until the current indicated on the ammeter is
at the desired test value. Caution: In case of open circuits at joints or connections, the voltage
across the defective joint or connection will be in the order of 50-100 volts.
5. DISINFECTION OF WATER MAINS
5.1 General
All pipelines installed shall be disinfected with a strong chlorine solution. Disinfecting may be
done concurrently with pressure and leakage testing or after pressure and leakage testing at
the option of the Contractor. Each section line that is repaired shall be disinfected after such
repairs are made. All necessary disinfection equipment and materials shall be provided by the
Contractor.
5.2 Flushing
The pipeline shall be flushed at a velocity of at least 2.5 feet per second immediately prior to
disinfection. A 24-hour notice is required to the City Water Department for pipeline flushing.
5.3 Disinfectants
Disinfection shall be performed using either chlorine gas or calcium hypochlorite solution.
Chlorine gas shall conform to AWWA 8301 and shall be handled under pressure as an
aqueous solution. Calcium hypochlorite shall conform to AWWA 8300 and shall be granules
with 70 percent available chlorine.
Standard Detail Specifications
Water Main Systems
Albertville, MN
04/00
Page W-11
5.4 Feeding
Chlorine gas shall be used only as a solution. Introduction of chlorine gas into the pipeline
directly will not be permitted. When chlorine is used, a chlorinator and booster pump with
injector shall be provided.
Calcium hypochlorite shall be made into a solution and pumped into the pipeline with a
suitable chemical feed pump.
5.5 Application
Pipelines shall be disinfected by either the continuous feed method or the slug method.
In using the continuous feed method, chlorine feed shall be proportional to the rate of flow into
the pipe so the entering water contains at least 50 mg/l of available chlorine. Chlorine
application shall be continuous until the entire pipeline is filled with the chlorine solution. The
treated water shall be retained in the pipeline for at least 24 hours and the chlorine residual
at the end of the period shall be at least 25 mg/l.
In using the slug method, chlorine shall be fed at a rate that will produce at least 300 mg/l in
the water entering the pipeline and a sufficient quantity of water shall be chlorinated so all
parts of the pipeline will be exposed to chlorine concentration of 300 mgll for at least 3 hours.
During disinfection all valves and hydrants shall be operated to ensure all appurtenances are
disinfected.
5.6 Bacteriological Tests
The chlorine solution shall be flushed out of the line and samples shall be collected and tested
for bacteriological quality after the line has set for a minimum of 24 hours. Thesamples shall
be collected by the City Water Department personnel and the cost of these tests paid for by
the Contractor. A 24-hour notice is required to the City Water Department for pipeline flushing.
5.7 Repeat Testing

have a least a 24-hour notice for said inspection.
6. WATER MAINS CROSSING SEWERS
Water mains crossing sanitary sewers, storm sewers, or house sewers shall be laid to provide
a separation of at least 18 inches between the bottom of the water main and the top of the
sewer. When local conditions prevent a vertical separation as described, the following shall
be used:
1. Sewers passing over or under water main shall be constructed of materials equal to
water main standards of construction.
2. Water mains passing under sewers shall, in addition, be protected by providing:
1. A vertical separation of at least 18 inches between the bottom of the sewer and the
top of the water main.
2. Adequate structural support for the sewers to prevent excessive deflection of joints
and settling on and breaking the water mains.
3. The length of water pipe be centered at the point of crossing so joints will be
equidistant and as far as possible from the sewer.
Water mains shall be laid at least 10 feet horizontally from any sanitary sewer, storm sewer
or sewer manhole whenever possible. When local conditions prevent a horizontal separation
of 10 feet, a water main may be laid closer to a storm or sanitary sewer provided that:
1. The bottom of the main is a least 18 inches above the top of the sewer;
2. Where this vertical separation cannot be obtained, the sewer shall be constructed of
materials and with joints that are equivalent to water main standards of construction and
shall be pressure tested to assure water tightness prior to backfilling.
7. MAINTAINING WATER SERVICE
While construction is underway, the Contractor shall maintain water service to existing users
on a continuous basis until service from the newly installed mains can be restored. The means
and methods used are subject to the acceptance of the Engineer. Overland service lines
connected to a hydrant via a common header is recommended.
All service lines, headers, connections, and appurtenances shall be disinfected in accordance
with Minnesota Health Department and AWWA rules and regulations.
