Germany-based OSSCAD GmbH & Co. KG specialises in the design, development, support and technical consulting for optical sensor technologies. The company places a special emphasis on the ongoing development and promotion of its products in the area of CIPP (cured-in-place pipe) rehabilitation and monitoring of buried energy cables. In 2017 OSSCAD will celebrate its 10th anniversary.
As part of its product range OSSCAD has developed the CMS measuring system for the monitoring of the liner curing process during pipeline rehabilitation operations of both sewer and drinking (potable) water pipes. The CMS system consists of a CMS measuring instrument (laser radar), a fibre optic cable (LWL cable) as a line-shaped temperature sensor (CMS sensor cable) and the CMS application software (VISCOM liner) for the evaluation and visualisation of the curing temperature measuring data.

The BRAWOLINER® 3D lining system was recently utilised on a very challenging sewer rehabilitation project which was part of the on-going £1 million Torbay Sewer Rehabilitation Program being undertaken by South West Water (SWW) in association with its consulting engineer AECOM. The main contractor for the works was Balfour Beatty Utility Solutions Ltd (BBUSL).
In an ‘old town’ area of Torquay on the English Riviera, a section of clayware sewer pipeline running beneath steep steps (with 85 steps) connecting Melville Street and Rock Road was found to be in need of renovation after CCTV inspection and analysis. These steps are believed to be the steepest in the town.
Originally, the proposed solution was to replace the sewer using the traditional ‘open cut’ technique. The steps are a maximum of 2 m in width and run adjacent to dwellings on the one side and a substantial retaining wall on the other. The sewer is at a depth of between 2 m and 2.5 m. An inspection of the site showed that to open cut the section would require structural surveys to be undertaken on the properties and wall adjacent to these steps together with specialist designed excavation and shoring techniques to safeguard the structures stability during the excavation operation. Therefore, the client sought a trenchless rehabilitation solution that would eliminate the need to open cut the pipeline.
Whilst this might sound an easy option given the number of renovation systems currently available, practically this was far from the truth. Read More
It is widely known that a significant proportion of East Anglia relies for its existence on the effective operation of widespread land drainage networks. Without these networks much of the region would not be able to function in the way that it does and the population would be hard pressed to continue their lifestyles in the way they do in the modern world due to the high ground water levels.
Much of the drainage to keep ground water levels in check is achieved using local pumping stations that take water from the land drainage network and pump it into local rivers and drainage channels that remove the water off the land and out to sea so keeping the local area from flooding. These pumping stations are under the control of the Internal Drainage Boards (IDB’s).
However, when undertaking rehabilitation of a pumping station at a site near Kings Lynn, a reverse syphon carrying water from the pump station to the main drainage channels that fed the local estuary, was found to have failed and there were fears that water normally carried by the syphon away from its local pumping station would cause problems.
The failure of the syphon meant that water from the pumping station was not, as would normally be the case, all removed from the network but that it was being returned back into and potentially undermining the pumping station due to leakage in the syphon. This was also causing the river bank near the pumping station to erode. It was causing problems in the pump station as water was recycling, meaning the pump station was working significantly harder than it should, incurring extra cost and potentially could lead to significant flooding problems for the area.

Marlborough College in Wiltshire, UK is a highly respected independent school for day and boarding pupils. The College was established in 1843 by a group of Church of England clergymen. Today the College is a fully co-educational establishment catering for about 930 pupils with the great majority (98%) being boarders. The Duchess of Cambridge is a former pupil.
Of the full boarding schools across the country, Marlborough was recently ranked 4th with an 82% acceptance rate for pupils to the UK’s top 30 universities, a rating bettered only by Westminster School, St Paul’s School and Winchester College.
As with all buildings that have been in use for some considerable time, Marlborough College’s infrastructure is constantly reviewed and repaired or upgraded as necessary.
Recently part of this ongoing process there was a need for the renovation of a significant part of the College’s North Block including the building’s rainwater drainage system. The system comprises very old and ornate cast iron rain water downpipes that in places are hidden within the fabric of the wall and which take rainwater from the roof to ground level drains. In places these downpipes were leaking causing damp problems within the building. Given their design, location and accessibility they would have been very difficult to replace in keeping with the original building construction so an alternative to full replacement was sought.

The North of England has long been famous for not just its wonderful landscapes, world renowned cities and the character of its people, it is also globally recognised as a major centre in the growth of the industrial economies we see today. Whilst like many parts of the UK the region has had its ups and downs alongside the vagaries of the economy it still boasts some of the UK’s largest industrial facilities.
Not least of these is a major soft drinks manufacturing plant which was recently the site of a challenging pipeline rehabilitation project undertaken by DALROD, a family run drainage industry service provider established in Peterborough in 1985. The project was completed using the BRAWOLINER® HT CIPP liner system, supplied by the UK Brawoliner distributor C.J. Kelly Associates of Peterborough. The project had apparently been looked at by other rehabilitation contractors but dismissed as not possible using currently available techniques.
Sewer lining specialist DALROD Cambridgeshire was recently involved in a technically challenging project to keep water flowing to a major cement works in Essex, UK. The site is part of an industrial development in the mined out area of what is still elsewhere a working quarry site, investigations showed that the pipes which carried away fresh water between to two lakes was in need of rehabilitation. However, the fact that the site was industrialised with other operations as well as the cement mixing works, meant that operating conditions for any rehabilitation works would be far from easy.
The client expressly demanded that the rehabilitation be completed in a set timeframe with all traffic management being undertaken by the contractor and most of all that not only during the rehabilitation works but subsequently there should be no pollution created by the products used to complete the works.

Sewer Lining & Steam Curing
BRAWOLINER ® was developed especially for the rehabilitation of small diameter pipes (50 to 225 mm) with multiple bends of up to 90° and can accommodate changes in diameter.
BRAWO® SteamUnit offers a comparably compact but efficient steam generator. With a heat output of 56 KW the diesel-fired device produces a steam quantity of 50 kg per hour. Thus the curing of longer piping sections in buildings or buried pipes is possible. Read More
