III. <strong>Technology</strong> Design, Installation, and QA/QC In<strong>for</strong>mation<br />
Product Standards All requirements <strong>for</strong> the technology's application in drinking water pipes in<br />
Germany, the KTW recommendations <strong>for</strong> application <strong>of</strong> plastics in drinking water<br />
pipes and the DVGW W270 Recommended Practice (German Association <strong>of</strong> Gas<br />
and Water), have been complied with. The relevant U.S. certificate, NSF 61<br />
(National Sanitation Foundation), has been applied <strong>for</strong> and is expected in 2010.<br />
Design Standards Not available<br />
Design Life Range 50 years per DVGW certification<br />
Installation Standards Not available<br />
Installation<br />
Methodology<br />
The liner has to be pressed through calibrated rollers be<strong>for</strong>e it is pushed into the<br />
pipe. Liner is then wound on a pressure drum and bolted into an inversion cone<br />
attached to the host pipe. The liner is inverted inside the host pipe and the process<br />
ends when the liner reaches the catch basket.<br />
