MAJOR WEST OF SCOTLAND SEWER PROGRAMME NEARS COMPLETION
A major 8.5 million programme to rejuvenate ageing sewers in major towns and cities throughout the West of Scotland has been completed by Insituform Technologies. The contract was awarded to Insituform by Scottish Water for cured in place pipe (CIPP) lining of deteriorated sewers. In total 51 Kilometres of sewers have been lined over a three year period. This will add at least 50 years working life to the sewers, some of which are a hundred years old.

Speed has been an essential element in the high tech operation to reverse decline. Scottish Water has created an extensive video database of their sewer network that allowed areas for priority treatment to be identified to help Insituform to accurately cost the work involved. Having agreed the scope of work site activity proceeded rapidly.
In addition to being pioneers of the CIPP process, Insituform are the only contractor to take responsibility for the entire lining operation. Polyester needle-felt liners are manufactured to the correct thickness and weight in their own factory in the Midlands. These bespoke liners are then vacuum impregnated with chilled thermosetting resins at their Wakefield factory before transportation to site in refrigerated vehicles. The inversion process and heating of the displacement water is closely controlled to ensure liners are fully cured. All stages of manufacture and installation are subject to ISO 9000 quality procedures.
Being a high speed and trenchless technique the Insituform process has had a minimal environmental impact with less traffic disruption, fewer HGV movements and only minor excavations at points of entry and exit.
