International Award Winning Engineering

Hydrascan Ltd, the R & D subsidiary of Kilbride Environmental Services Ltd, was formed to meet the challenge issued by Northumbria Water to clean large diameter water mains in North East England. The first product developed by Hydrascan was the Typhoon System which went on to carry out cleaning works in AMP 5 on over 50km of water mains ranging in diameters from 10 inch to 38 inches.

The system was awarded the Innovation Award by the United Kingdom Society for Trenchless Technology in 2009 and went on subsequently to be awarded the International Product of the Year Award in 2011 by the International Society for Trenchless Technology and was shortlisted for the Engineer Technology and Innovation Award 2010.


The Typhoon jetting systems delivers impeccable cleaning results for both large and medium sized water mains.

Offering a long range solution from a single point access, Typhoon is ideal for both urban and rural environments, cleaning around multiple bends and up to valve faces.  Radial fans jets ensure a total 360 degree clean of internal pipe walls.  Water pressure and jetting angles can be adjusted to ensure pipe linings are unaffected by the cleaning process.


Travels at up to 1.5m/s along the pipe before returning and cleaning at 0.5m/s to 0.1m/s


The Typhoon System can clean up to 1.2km from a single access point


The Typhoon System easily cleans 6 into to 72 inch diameter pipe

The Transformer

The Transformer Pig is the latest innovation in the Typhoon Cleaning System range. Developed to enable cleaning of very large diameter water mains on the Manchester Ring Main, this new technology means a single pig can clean water mains with diameters that vary between 32 and 72 inches. With the capability to fit access pipes of 24 inches and above, the system doesn’t require large open excavation pits and can be propelled to a range of 600 metres using a single water recycling vehicle. The system is jetted to the target area in propulsion mode and withdrawn when in cleaning mode. The transformer ‘legs’ are opened and collapsed depending on the diameter of the pipe and cleaning is by way of water jetting against the pipe walls. Wheels on the transformer legs ensure the pig moves freely and the wall and any linings are protected.
