Malaysia
To allow for new highway construction, the Federal Government Administrative Center of Malaysia found it necessary to reroute two 6.6-kilometer segments of two 72" water mains running 22 kilometers between a reservoir and a water treatment plant outside Putrajaya, Malaysia. Both 72" lines were steel with internal concrete linings.
Since the government agency wanted to avoid shutdown of this critical potable water supply, TDW Services, Inc., was contracted to perform the hot tapping and plugging operations. Four 48" hot taps were made in the two original 72" lines, and four 60" taps were accomplished on the new 72" permanent bypass lines. The 48" taps were completed in four hours each, while the 60" taps were finished in six hours each.
TDW Services Technicians installed double STOPPLE® Plugging Machines with 48" x 72" folding heads on the 48" taps. This strategy saved money and time through the use of smaller fittings, shorter tapping times, and resulted in reduced weight on the line. The 48" folding heads were inserted through the 48" taps, then opened up to successfully plug the big 72" water mains. TDW effectively completed its part of this water development supply project without inconvenience to the local Malaysian residents and customers. |
