Since winning the UKSTT Environmental Award last year for a collaborative project on behalf of South West Water, Sanivar’s presence in the pipe lining sector has gone from strength to strength with a healthy pipeline of opportunities including a large diameter refurbishment in Jersey and successful projects delivered for several leading UK WASCs including Anglian Water and Yorkshire Water.
Much of this activity has been focused on our unique pull through liner SaniTube which is proving to be a ‘go to’ solution for rising main repairs particularly where access or service interruptions are critical factors as was the case on a project delivered by PSS at Stansfield for Anglian Water.
The project involved the restoration of a 100mm rising main, part of which was installed under a bridge crossing, adjacent to a pumping station. The existing PVC rising main suffered a history of bursts, and a recent leak had caused effluence to leak through the bridge decking and into a neighbouring water course.
Without refurbishment, the PVC pipe posed a significant risk of pollution to the water course and adjacent amenity assets, in an area popular with walkers, Anglian Water sought a ‘no dig’ solution to minimise customer disruption and to avoid the prohibitive costs of accessing and replacing the main through traditional civil works.
SaniTube provided the only practical solution for this complex project due to :
• Flexibility – provided by the liner’s ultra-thin wall construction
• Durability – through a pressure rating in excess of 10 bar
• Efficiency – rapid installation enabled by lack of curing or wetting-out processes
• Adaptability – being able to accommodate various pipe conditions
• Sanivar’s commitment to collaborative working and on-site support
In addition to our growing portfolio of work in waste water we are now at an advanced stage of testing to achieve Regulation 31 approval and extend our operations into potable water applications. This coincides with the successful completion of a major clean water project in Wellington, New Zealand where parallel 150mm diameter mains were refurbished setting a new record for for installation length at 1.8km in a single pull. The mains were refurbished and returned to service within a single working day .. and all in the middle of Lock Down with logistical challenges over quarantine and safe working that included shipping the liner and installation teams out to New Zealand on a returning repatriation flight under permission from the New Zealand government.
The migration of Sanivar into potable water means that we are looking to expand our UK presence through distributors and in particular waste water contractors and we would be very interested in working with UKSTT members to jointly develop sector wide opportunities. Projects would be fully evaluated by ourselves in advance of supply and installations could be supported where necessary by our in house installation advisors. Any member organisations wanting to discuss potential involvement in this exciting collaboration should initially contact Tim Farley to discuss.
