CAST IRON SOLUTION WITH BRAWOLINER® HT

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.

MC & BRAWOLINER AIDS COMPLETION OF CHALLENGING FRESH WATER PIPE REHABILITATION

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.

DALROD UTILISES BRAWOLINER TO COMPLETE A CHALLENGING RENOVATION PROJECT NEAR ELY CATHEDRAL

The problem was that some 5 years ago pipeline survey works highlighted that ground movement has caused deterioration and cracking in sewers the vicinity of the cathedral, with the situation being carefully monitored by DALROD since. A more recent survey indicated that the sewers were now in need of relining, which is normally a straightforward procedure for the DALROD team. However, in this instance, one particular 225 mm (9 in) diameter sewer system, which was approximately 2.8 to 3.0 metres deep, had particularly difficult access problems. The access was tricky for various reasons including that the pipeline runs below a terrace of pre-war-built houses with no rodable access points from most of the lateral connections as well as poor access to most of the gardens of each individual property which made it difficult to reopen the lateral connections subsequent to the main line lining work. In addition to the access difficulties, most of the properties comprised 3-storey buildings that had live systems which could not be shut down adding to the general operational difficulties. All of this meant that Dal Rod had to reline the sewers whilst the system was live and over-pump where flows required it to make sure that no flooding occurred in the basements of any of the 3-storey buildings during the works. This was clearly a case for a trenchless lining or 'no-dig' solution. Having examined the options it was decided that Brawoliner was best suited to the work, a system which the DALROD team had previously utilised on similar jobs.

UV LINING AIDES MAJOR POWER STATION RENOVATION WORKS

AES Kilroot Power Station (KPS), near Carrickfergus, some 12 miles northeast of Belfast, is an oil and coal burning power station that produces around one third of Northern Ireland’s electricity. Being such an important power generator for the area, however, the current facility must be kept at its best efficiency and operational performance at all times. As part of the ongoing maintenance work to ensure this performance is achieved, a CCTV survey of the existing 420 mm diameter, steel, sea water pipelines which have been in use for over 30 years was undertaken. The survey showed signs of severe encrustation and corrosion, with, in places, up to 30% of the pipe cross section being obstructed. Corrosion had also removed a length of approximately 7.0 m in the invert of one pipe and there were also numerous small holes throughout the length of the pipes which allowed the ingress of water in the form of jets and seepage.

MULTI-DIAMETER AND EXTRA STRENGTH LINERS FOR THE UK RENOVATION MARKET

The rehabilitation of lateral connection pipes and service drains with in-built changes in diameter sometimes presents a major challenge for many existing rehabilitation technologies. Given the occurrence of such pipe structures, there has for some time been a need for a liner system that can accommodate such diameter fluctuations during the installation process without the need to excavate to access the diameter change location or design a liner with the diameter change in the ‘right position’ before installation. This is particularly the case where, in one single pipe length, large increases in diameter exist, for example from DN 100 to DN 150. The new BRAWOLINER® 3D liner system was developed especially

INSTALLATION SUCCESS FOR NEW BRAWOLINER® CONTRACTOR

Cambridgeshire-based drainage contractor Dal-Rod Cambridgeshire recently undertook its first ever lining operation with the BRAWOLINER® system on a project in Epping Forrest. Working for managing contractor AMEC, the project was required to renovate drains at the Epping Forest college campus. The local authority required rehabilitation of the sewer, which runs under a main highway between the college and a public walk way, to be completed using Brawoliner® as a preferred method of repair. The majority of the pipes comprised 225 mm or 150 mm diameter pipes which were suffering from numerous cracks, joint displacements and fibrous root intrusions, as well as egress & ingress of sewer and ground water flows.
