HDPE Piping (SD-03, Product Data), FIO HDPE Joint Fusion Certification (SD-07, Certificates), GA Pressure Test Results (SD-06, Test Reports), FIO Delivery, Storage, and Handling:

Deliver piping with factory applied end-caps. Maintain end caps through shipping, storage, and handling to prevent pipe-end damage and to prevent entry of dirt, debris, and moisture.

Protect flanges, fittings, and specialties from moisture and dirt.

Store piping, fittings, and accessories to protect from direct sunlight. Support piping to prevent sagging and bending.

PRODUCTS

GENERAL

All waterlines, pipes, and fittings shall be new and unused, of the type, pressure rating or class, and size specified and as shown on the drawings, and in compliance with the Reduction of Lead in Drinking Water Act.

Comply with NSF 61 for materials for water-service piping and specialties, with piping bearing the label, stamp, or other markings by the specified testing agency.

Unless otherwise indicated, the minimum pressure requirement for piping, specialties, and fittings is 160 psig.

MATERIALS

HDPE Piping: PE-3408 as defined in ASTM D 1248, minimum cell classification 345464C per ASTM D 3350, SDR 9.

For pipe sizes larger than 2” diameter, provide in 40-foot lengths rather than rolls.

Dissimilar Pipe Couplings: Compression type, transition fittings from plastic piping to various pipes, Cepex performance series as manufactured by Cepex Holding, S.A., or approved equal.

EXECUTION

GENERAL

Before placing in position, clean pipe, fittings, valves, and accessories, and maintain in a clean condition.

Do not under any circumstances drop or dump pipe, fittings, valves, or any other water line material into trenches.

Cut pipe in a neat workmanlike manner accurately to length established at the site and work into place without springing or forcing.

Grade the pipeline in straight lines; avoid the formation of dips and low points.

Lay pipe such that the full length of each section of pipe and each fitting will rest solidly on the pipe bedding.

Excavate recesses to accommodate bells, joints, and couplings.

Keep trenches free of water until joints have been properly made.

Do not lay pipe when conditions of trench or weather prevent installation.

Do not exceed 5 degrees alignment, or the manufacturer’s recommended alignment offset, for adjacent joints, whichever is more stringent.

Penetrations:

Provide ductile-iron or Schedule 40 steel wall sleeves for pipe passing through walls of valve boxes and structures.

Fill annular space between walls and sleeves with rich cement mortar.

Fill annular space between pipe and sleeves with mastic.

Provide thrust blocks in the size and position as indicated in the drawings.

Provide tees at all branch connections to the main, and with the same diameter as the largest pipe connected to the tee.

When work is not in progress, securely close open ends of pipe and fittings.

Do not place pipe in the trench until the Contracting Officer approves the trench and bedding.

Backfill the pipe within 24 hours after installing the pipe in the trench, leaving the joints and one foot of pipe on each side of each joint until testing is complete.

INSTALLATION

HDPE Pipe Install in accordance with ASTM D 2774.

Jointing per ASTM D 2657m Technique I – Socket Fusion, or Technique II – Butt Fusion, and per the manufacturer’s written instructions.

Use certified HDPE jointing personnel or provide qualifications showing at least three years’ experience in HDPE fusion techniques.

CLEANING

Before testing, clean new water distribution piping systems and parts of existing systems that have been altered, extended, or repaired by high-pressure water jet or mechanical means.

Flush water lines or modifications of an existing water system, and all of the existing system immediately downstream, to remove sediment.

During flushing operations, operate all valves, hydrants, hose bibs, and other outlets.

Flush system with clean potable water until dirty water does not appear at points of outlet.

PRESSURE TESTING

Conduct piping tests before joints are covered and after thrust blocks, if required, have hardened sufficiently. Keep joints uncovered until testing is completed satisfactorily.

Furnish personnel, pump, pipe, gauge, measuring device, connections, and all other necessary apparatus for testing, and are subject to approval by the Contracting Officer.

Test all newly constructed portions of the water system, including water mains, service lines, fittings, valves, and hydrants. Test new water line extensions and modifications to an existing water system at the specified test pressure.

Provide and use only potable water.

Test water lines in sections not to exceed 2,000 linear feet in length or a maximum pressure differential of 30 psi in the test section.

Expansion Test Procedure Slowly fill each valve or plugged test section of pipe with water. Fill by means of a pump connected to a pipe. Operate all hydrants and taps to bleed entrapped air from test section. Operate pump continuously during bleeding operations, and such that the pump takes suction from a small auxiliary tank for measuring the water pumped into the test section.

Raise internal pressure of the system by pumping in water. Increase pressure in 50-psig increments and inspect each joint between increments. Raise internal pressure to a test pressure of 1.5 times the working pressure at the point of testing based on the elevation of the lowest point of the line or section under test, or other test pressure as approved by the Contracting Officer.

Allow the system to stabilize for three (3) hours at the test pressure before conducting the hydrostatic test. Make up liquid may be added during this time to return to test pressure.

After obtaining the approved test pressure, record the water level in the auxiliary tank.

Test Phase Procedure Begin test phase immediately after recording the water level, for two (2) hours.

Reduce the test pressure by 10 psi, and stop adding test liquid. If the pressure remains steady, within 5% of the target value, for one (1) hour, no leakage is indicated.

Verify leakage with the Contracting Officer.

Locate and replace any defective pipe, fittings, valves, joints, and hydrants as required, if there is leakage in excess of the above requires, at no cost to the Government, until the leakage is within the specified allowance.

All visible leaks are to be repaired regardless of the amount of leakage. Flush the system, and repeat the pressure test until leak is repaired.

The use of paints, asphalts, tars, enamels, or other types of pipe compounds to eliminate leaks is not permitted.

Backfill the water lines after the Contracting Officer approves the testing.

Furnish a written report to the Contracting Officer, describing the results of each test. Identify specific portions of pipeline tested, the pressure, the duration of the tests, and the amount of leakage.
