III. <strong>Technology</strong> Design, Installation, and QA/QC In<strong>for</strong>mation<br />
Product Standards PE pipe is approved <strong>for</strong> potable water service in most countries, and can be<br />
specified to withstand a wide range <strong>of</strong> internal pressures and burial depths<br />
Design Standards PE pipes used in the Swagelining process are manufactured to ISO, AGA,<br />
ASTIVI, and API standards, so lines renewed by this process have known<br />
physical properties and an established service life.<br />
Design Life Range As per specification <strong>of</strong> PE pipe used.<br />
Installation Standards As per client specifications.<br />
Installation Methodology As per sliplining, but the PE pipe is pulled through a die prior to being pulled<br />
through the host pipe.<br />
QA/QC Not available<br />
IV. Operation and <strong>Main</strong>tenance Requirements<br />
O&M Needs Resistant to corrosion, abrasion, and ground movement.<br />
Repair Requirements <strong>for</strong> Standard as PE pipe is used.<br />
Rehabilitated Sections<br />
V. Costs<br />
Key Cost Factors Social & economic cost <strong>of</strong> open cut replacement versus trenchless rehabilitation<br />
<strong>of</strong> existing pipe lines.<br />
List <strong>of</strong> parameters or key drivers <strong>for</strong> the costs. Labor, transport, PE prices &<br />
delivery, joints (price & delivery), mobilization, pit excavation, cleaning,<br />
inspection, gauging, lining, testing, re-connection, site restoration.<br />
Case Study Costs Not available<br />
