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.

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.

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

BRAWOLINER® RENOVATES JERSEY SEWERS

Since 2004 Bell Services Ltd, the Dyno Rod franchise holder for the Channel Island of Jersey, has been using the German-manufactured Brawoliner® system, from KOB (Karl Otto Braun KG) of Wolfstein, for the lining of deteriorated pitch fibre and vitrified clayware foul and surface water pipes across the island. Some 2,000 m of Brawoliner® has been installed over the last 3 years in either 100 mm (4”) diameter, 150 mm (6”) diameter, with some 200 mm (9”) diameter installations. Clients have included The States of Jersey Public Services, Education Sport & Culture (local schools), Health & Social Services (General Hospital) and Housing Departments as well as Public Houses and Residential Homes and numerous properties across the island. The work has been undertaken in close association with CJ Kelly Associated Ltd, an independent specialist sewer renovation consultant and KOB’s technical representative the UK and Éire.

UNIVERSITY OF EAST ANGLIA – SEWER CLEANING AND LINING PROJECT WITH MC BUILDING CHEMICALS

As part of a corridor link and long term maintenance project, Norwich-based utility consultant Kier Eastern (part of the Kier Group) recently undertook a programme of sewer cleaning and lining work on behalf of University of East Anglia (UEA), under the direction of Tim French. The contract to complete the necessary work was awarded to Dyno-Rod of Mahoney Green, Rackheath, Norwich, with lead project engineers J Vaughan and S Plane. The work was to be undertaken beneath the Sainsbury Centre for Visual Arts, part of UEA, a prestigious and well known building in Norwich and comprised the rehabilitation of existing cast iron pipe work, which was in a poor condition and in many locations, badly pitted and corroded. Dyno-Rod advised that the most sensible and practical solution would be to Dyno-Line the existing drainage pipe. The works were undertaken as part of the overall improvement and refurbishment of the Sainsbury Centre. The work would result in a new pipe within the old damaged pipe, which would be resilient to ground movement, impervious to leaks or root penetration, and which offers minimal cross-sectional loss (and therefore carrying capacity) whilst increasing hydraulic efficiency. The lining is also guaranteed for 15 years.

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.

MANHOLE RENOVATION- THE KEY TO LONG-TERM WASTEWATER NETWORK DURABILITY

MC Construction Chemicals, along with its UK representative CJ Kelly Associates Ltd, is pleased to announce the launch of a new all-encompassing Manhole Renovation product range, ‘ombran’. The most recent statistics, reported by some 27 countries across Europe, have shown that there are some 60 million manholes currently in operation. A further report showed that, of these manholes, around 12% (or 7.2 million) are in a state of deterioration to the point where renewal is required. Furthermore, cost estimates also showed that the average cost of fully rehabilitating one manhole is about €2,250. This equates to a total of around €16.2 billion for the 7.2 million manholes needing repair.
