2.2 PIPE DESIGN REQUIREMENTS

.1 Pipe: The pipe shall be manufactured in accordance with AWWA C950. The

pipe shall meet the following cell limits of AWWA C950: Type 1, Liner C,

Grade 4. The pipe shall be field connected with glass reinforced sleeve

couplings that utilize elastomeric sealing gaskets as the sole means to

maintain joint water tightness. The couplings shall be manufactured using the

same process as the pipe. The joints shall utilize elastomeric sealing gaskets

meeting the performance requirements of ASTM D4161.

.2 The pipe shall be manufactured using a filament wound mandrel process

utilizing continuous glass fibre reinforcements in the circumferential

direction. Both continuous glass fibre rovings and chopped roving will be

incorporated for high hoop strength and axial reinforcement. A sand fortifier

shall be used to provide increased stiffness with placement near the neutral

axis in the core.

.3 Pipe design is governed by the following criteria unless specifically noted

otherwise:

.1 Internal Working Pressure: 690 kPa

.2 Field Test Pressure: 1,050 kPa

.3 Water Hammer Allowance: 40%

.4 Trench Supported Full Vacuum: 100 kPa

.5 Live Load: HS-20

.6 Variable Depth of Earth Cover: as shown on drawings

.4 Pipe pressure class, wall thickness or dimension ratio shown on the Contract

Drawings or specified elsewhere in the Contract Documents take precedence

and may vary from those determined through the application of Design Guide

methodologies and procedures.

.5 This does not relieve the pipe supplier from responsibility for conducting an

independent analysis to confirm that dimensional information specified or

shown elsewhere satisfies the design criteria. In the event that Design Guide

procedures result in a wall section thicker than that shown or specified

elsewhere, use the larger of the two values.

.6 NSF/ANSI 61 compliant materials in contact with potable water.

radius is less than 2 ½ times the pipe diameter, stresses shall be checked and

the pressure class increased if necessary.
