From the centerline of the pipe, fittings and appurtenances to a depth of one (1) foot above the

top of the pipe, the trench shall be backfilled by hand or by approved mechanical methods.

Compaction shall not be less than ninety five percent (95%) of maximum dry density as

determined by ASTM Test Method D-1557 (latest revision). The Contractor shall use special

care in placing this portion of the backfill so as to avoid damaging or moving the pipe. This

layer of backfill shall be consolidated by means of hand held vibratory compactors.

From one (1) foot above the pipe, the remainder of the backfill shall be placed and compacted in

one (1) foot lifts. Each layer shall be compacted to not less than ninety five percent (95%) of

maximum dry density as determined by ASTM Test Method D-1557 (latest revision).

Compaction methods shall be submitted in writing to and approved by the Engineer prior to

commencement of any work.

There is no guarantee that all excavation can be done by use of machinery. In some cases, the

pipe location may preclude the use of machinery. In this event, the Contractor will be required

to perform this Work at the same unit price bid in his proposal.

Thrust Restraint

Poured concrete thrust blocks shall be provided at all horizontal bends, mechanical joint caps and

tees and all locations indicated on the plans. Joints at fittings where thrust blocks are poured

shall be wrapped with polyethylene. All mechanical joints (i.e., valves and fittings) shall be

restrained by means of ductile iron retainer glands except where rod type restraint is specifically

called for on the plans or ordered by the Engineer. Push-on joint restrainers shall be used on all

push-on pipe joints for a distance of 27 feet on each side of all retainer glands. No more than

one pipe joint shall be allowed within that 27 feet of pipe. Concrete shall be mixed and placed in

accordance with the pertinent section of these Specifications.

Restraint of push-on joints shall be accomplished by means of using FIELD LOK 350 gaskets or

approved equal push-on joint restrainers. The push-on pipe joint restrainers shall be installed in

accordance with the manufacturer’s recommendations.

Mechanical joint restrainer glands shall be installed by first tightening the tee head bolts and then

making the set screws finger-tight against the pipe. All set screws shall be torqued to

manufacturer's recommendations, proceeding alternately on opposite sides of the pipe.

At mechanical joints to be restrained by rods, the proper number of tee head bolts for the

particular pipe size shall be removed and replaced with tiebolts. Tiebolts with washers shall be

used on bell flange slots. The mechanical joint gland shall be restrained by nuts on the threaded

portion of the tiebolts. Joint restraint shall be accomplished by placing threaded rods through

corresponding tiebolts at glands on each end of the length to be restrained and by running nuts on

the rods until tension is obtained. Four-inch, six-inch and eight-inch joints shall be restrained by

two rods; 10-inch, 12-inch and 16-inch joints shall be restrained by four rods.

Where connections are to be made between new water mains and existing water mains, any

unspecified materials required shall be utilized only after inspection and approval by the

Engineer. All connections between new mains and existing mains shall be made only at such

times as, and in a manner, approved by the Engineer. The approximate locations of connections

between new mains and existing mains are shown on the drawings; the exact locations will be

determined in the field by the Engineer.

The cutting of an existing water main where connection is to be made to a new water main shall

be done in a neat manner so as to leave a smooth end at right angles to the axis of the pipe. The

open end of the section of existing water main to be abandoned shall be sealed with concrete

before backfilling a minimum of 5' from the new facilities.

Abandonment of Existing Facilities

Abandonment of water facilities shall be as described on the plans. All open ends of abandoned

pipelines or conduits which are created or exposed by the Contractor and will not be removed

from the roadway, shall be sealed with concrete before backfilling. Valves to be abandoned shall

be closed (unless otherwise indicated on the Plans) and the valve box tops shall be removed and

properly disposed of. Where the plans call for salvaging existing water main and appurtenances,

materials shall be delivered to the Water Department at the former Line Street Water Treatment

Plant.

Leakage Testing

Leakage testing shall be performed on all cleaned and lined water mains as well as new

installations where it is not possible to perform a pressure test. Leakage testing shall consist of a

visual inspection of all new facilities and connections under system pressure. The Contractor

shall furnish any temporary thrust restraint required for testing and any other apparatus and

personnel necessary to conduct the test at no cost to the Town. All visual leaks shall be repaired

by the Contractor at his own expense regardless of the amount of leakage. Any defective pipe,

fitting, valve or hydrant discovered as a consequence of this test shall become the property of the

Contractor and shall be removed from the job site and replaced at the Contractor's expense with

sound material. When hydrants are in the test section, the test shall be made against the closed

hydrant valve with the auxiliary gate valve open.

Any section failing the test shall be retested after the repairs have been made. The test shall be

repeated until satisfactory to the Engineer. The main shall be disinfected again if so directed by

the Engineer.

be coordinated through the Engineer and shall be the responsibility of the Contractor.

Disinfection

Disinfection shall be carried out in accordance with Method 2 under Methods of Disinfecting

Pipe in the Connecticut State Department of Health's Bulletin, "Protection and Disinfection of

Water Works Pipes and Structures”, as required by Section 19-13-B47 of the Connecticut State

Sanitary Code.

Coordination with the Manchester Water Department through the Engineer will be necessary and

shall be the responsibility of the Contractor.

Water mains less than 24-inches in diameter and up to 2,500 feet in length may be disinfected

using the Tablet Method instead of the Continuous Feed Method. Disinfection using the Tablet

Method shall be performed in accordance with the most current version of AWWA Standard

C651. Chemicals used in the Tablet Method shall meet the requirements of AWWA B300 of

latest revision and shall be certified to ANSI/NSF Standard 60. The Tablet Method shall not be

used if trench water or foreign material has entered the main.

When disinfecting using the Continuous Feed Method, mains shall be completely flushed after

the leakage test until all evidence of sediment is removed. A sodium hypochlorite solution or a

mixture of calcium hypochlorite and water shall be applied, with a proper regulating device at

the beginning of the pipe section to be disinfected, through a corporation stop in the newly lined

pipe. Hypochlorites utilized in this work shall meet the requirements of AWWA B300 of latest

revision.

Water from the existing distribution system entering the newly lined pipe shall be controlled to

flow slowly during the application of hypochlorite. The rate of sodium hypochlorite application

shall be in such proportion to the rate of water flowing through the pipe that the treated water

entering the newly lined pipe will have a concentration of chlorine residual of 50 parts per

million. There shall be a retention period of at least twenty-four (24) hours and preferably more.

The non-spore forming organisms shall be destroyed, and the chlorine residual after the retention

period at the extremity of the pipe shall be at least ten parts per million. When disinfecting

newly lined and/or installed water pipe involving more than one valved section, all valves shall

be operated while the pipeline is filled with the disinfecting agent. Hydrants and other

appurtenances shall also be operated for disinfection.

Final Flushing and Testing

After disinfecting for the minimum retention period, the pipe section shall be flushed until, upon

test, the quality of the water, both chemically and bacteriologically, is equal to the quality of the

water served to the public from the existing water supply. The procedure shall be repeated if

necessary until the water from the pipe section is satisfactory.

WATER MAIN

TS-151

Care must be exercised when disposing of water with high free chlorine residuals and shall be

performed in a manner that will not adversely impact the environment. Disposal of highly

chlorinated water to storm sewers shall be avoided without neutralization of the chlorine

residual. Neutralization of the chlorine residual remaining in the water can be accomplished by

application of a neutralization chemical. Chlorine neutralization methods and equipment shall be

submitted to the Engineer for approval. Discharge of highly chlorinated water directly to the

sanitary sewer maybe permitted in cases where surface discharge will pose a safety risk to the

general public.

Tests to determine the chlorine residual and the quality of the water in the new pipeline will be

performed by the Manchester Water Department. It shall be the responsibility of the Contractor

to coordinate with the Water Department to arrange for the testing at the proper time. No less

than twenty-four (24) hour notice shall be given when tests are to be performed.

Where connections are to be made between new water mains and existing water mains after

disinfection and flushing are completed, new materials shall be swabbed with a suitable

hypochlorite solution.

Pressure Testing

Newly installed water mains shall be pressure tested as directed by the Engineer. Pressure

testing and leakage testing shall be carried out in accordance with the appropriate paragraphs of

Section 4 of the latest revision of ANSI/AWWA C600 with the following clarifications and

qualifications.

All testing shall be performed after backfilling the completed pipeline. Before testing, the

Contractor shall submit in writing to the Engineer, his proposed method of testing the completed

pipeline. Testing shall begin only after approval by the Engineer of the proposed methods. Any

required coordination with the Water Department shall be conducted through the Engineer and

shall be the responsibility of the Contractor.

All new sections of water main shall be hydrostatically tested at a pressure of 150 pounds per

square inch for a period of at least two hours. "Pressurization" and "air removal" shall be

accomplished as specified in Sections 4.1.2 and 4.1.3 of the latest revision of ANSI/AWWA

C600. After the test pressure is applied, any defective pipe, fitting, valve or hydrant discovered

as a consequence of this pressure test shall become the property of the Contractor and shall be

removed from the job site and replaced at the Contractor's expense with sound material. The test

shall be repeated until satisfactory to the Engineer.

A leakage test shall be conducted concurrently with the pressure test. The Contractor shall

furnish all material, equipment, tools, labor and incidentals necessary to conduct the test.

Leakage will be defined as the quantity of water that must be supplied into the newly laid pipe,

or any valved section thereof, to maintain pressure within 5 psi of the specified test pressure after

the air in the pipeline has been expelled and the pipe has been filled with water. No pipe

Description: Clean existing conduit as required, as shown on the plans or as directed by the Engineer to

remove dirt and debris to facilitate the installation of new cable.

Construction Methods: Where cable is to be installed in existing conduit the conduit may have to be cleared prior to the

installation. Cleaning will only be necessary if the new cable cannot be easily installed in the existing

conduit. By field inspection, and with the concurrence of the Engineer, determine the sections of conduit

that require cleaning.

Remove all existing cable from conduit. Install temporary cable elsewhere, as necessary, to

maintain normal signalization complete with vehicle & pedestrian detection, EVPS, and coordination.

Clean the conduit by one of the following methods:

1) Rodding.

2) A high pressure jet spray, or air pressure.

3) By pulling a mandrel or ball through the conduit.

Submit in writing the anticipated method of cleaning the conduit to the Engineer for approval

prior to cleaning any conduit.

If the conduit is found damaged to any extent that the cleaning process will not clear the

obstruction, it will be the judgment of the Engineer whether to replace the entire conduit run or excavate

and replace only the damaged section.

If the existing conduit is found to be missing hardware such as bonding bushings and bond wire,

the missing material shall be provided and installed under this item prior to installation of the cable.
