Infusion system for small-diameter wastewater pipelines and the iPlus Composite system for medium- to large-diameter wastewater pipelines will be used for the first time in Singapore on this project. Insituform plans to use its air invert steam cure (AISC) technology to complete this project, which will reduce water and energy usage on the job site by approximately 95%.
 

Insituform has also received an additional US$1.4 million in orders to supply CIPP tube to third parties in Singapore. In 2009, PUB, Singapore's publicly-owned water utility, began work on a US$295 million rehabilitation program. This rehabilitation program is expected to be completed in 2014 and will upgrade over 700 miles of public sewers and 30 miles of pumping mains.
 

Insitu Envirotech's part of the rehabilitation programme is expected to begin in March 2010 and be completed by December 2011.
