Experts in all manor of drainage issues

Some recent UV-lining works at the Manor House estate in Hutton Henry, near Hartlepool, demonstrated the operational challenges which Jet Aire are often required to manage in the delivery of professional drainage solutions.

As part of our ongoing maintenance contract with Northumbrian Water, Jet Aire strengthened a 110m-long drainpipe, which traversed from one side of a valley to the other, suspended in a purpose-built frame, with our UV-lining system which inserts a glass reinforced polyester liner filled with a special resin. The liner was inflated with air and built-in UV lights cured the resin to effectively create a new pipe within the original 150mm-diameter pipe.

Before this work could be carried out, the pipe required a CCTV survey to establish the extent of the required repairs. The downstream manhole was located within woodland which meant it had to be cleaned out by jet vac and remote reel. The liner then had to be transported with a quad and trailer to take it to the downstream manhole.

The liner had to be pulled into position with a winch but, with access hampered by the woods, the winch and UV lining van were 30 metres away from the manhole. Our partner contractors, Seymour Civil Engineering, built scaffolding around the upstream manhole make it safe to work. Despite these challenges, the UV-lining was safely and successfully completed with maximum efficiency.

Jet Aire Director, Keith Ferris, said: “The local conditions of the Manor House Estate presented difficulties which are typical of many projects which Jet Aire undertake, but our UV-lining team, led by Lining Manager Gavin Brook, are very experienced in adapting to physical and environmental complexities. We have the operational versatility and expertise to navigate challenges like these and achieve timely solutions.”
