Latest product launches


Posted: Monday 7th June 2010

New technology which will save water authorities and their contractors millions of pounds cleaning and surveying water mains has been launched after successful trials with Northumbrian Water.

The Hydrascan Typhoon water jetting system, which uses a tethered ‘pig’ system developed from technology used in the oil & gas industry, allows contractors to clean pipes ranging from 6 to 60 inches in diameter.

Requiring only a single entry point, Typhoon will save millions in the cost of excavating and re-routing traffic for extended maintenance projects in both rural and urban environments and achieves high levels of cleaning in pipes lined with concrete, cement, bitumen or PE.

The technology, which can be fitted with imaging equipment for surveying pipe condition, allows the hydro powered pig to be jetted along a length of pipe where it will switch between propulsion and cleaning operations.

On its return, multi directional controlled water jets remove any build up on pipe walls allowing for expedient, thorough and environmentally friendly cleaning at ranges of up to 500 meters – totalling 1km in both directions from a single entry point.

Hydrascan Limited, based in Gateshead, is a company established to develop and enhance technology in the water industry. Technical director, Dr Neil Stutchbury, explained:

“We have been working on the Typhoon system since May 2007 and today believe we have the most effective and cost efficient system on the market.

“Compared to the Typhoon system, current ‘pigging’ and ‘swabbing’ methods require substantially more plant, equipment and machine operatives on site - each pipe length that requires cleaning necessitates an excavation at each end of the pipe length as access to both ends of the pipe is required and only average cleaning results can be obtained.

“The Typhoon system requires access at a single point only, it can clean up to a valve face and its plant and operative ‘footprint’ is as small as it gets within the industry – which is ideal for urban areas. Most importantly Typhoon’s cleaning results are excellent.

“This product is set to make a major contribution to the maintenance of mains water infrastructure in the UK and beyond. With the help of our contracting partners we can achieve the ultimate aim of leaving a lasting legacy which is cleaner water for all. In theory any good quality jetting company could provide this level of service with this equipment and appropriate training’’.

Hydrascan engineers have a professional background in the design of tethered and free swimming pigs in the oil and gas industries and the system is able to pass around pipe bends and flush out all waste to be pumped off-site and disposed of.

Last year Hydrascan won a contract to supply its cleaning technology to Lumsden & Carroll Civil Engineers to clean Northumbrian Water pipelines. The Northumbrian Water project manager Stuart Tilley said:

“The Hydrascan method of cleaning water mains has proved well suited to working in urban environments due to its small site set-up, the achievement of high specification cleaning over long lengths and the ability to negotiate bends, valves and fittings in the network. Furthermore, the water re-cycling feature clearly contributes to the low carbon footprint of the system’’.

Northumbrian Water used Hydrascan cleanliness results obtained during trials undertaken for them in 2007 to set their own in-house cleaning requirements in conjunction with the standards laid down by the DWI (Drinking Water Inspectorate) for Aluminium, Manganese and Iron deposits.
