Through the pipeline with Waterflow
5 June 2007, News release from WATERFLOW SERVICES GROUP
National innovation award goes to Waterflow
The United Kingdom Society for Trenchless Technology (UKSTT) has presented its 2007 Innovation Award to the Waterflow Group Plc for developments to the company's UV-cure pipe lining system.
This prestigious Award recognises advances to trenchless technology that further the scope and application of construction and rehabilitation techniques, minimising environmental impact and disruption. The presentation was made at the UKSTT Annual Awards Dinner held in Birmingham on 27 April 2007. During 2006 Waterflow introduced a new system for the renovation of gravity pipelines including drains, sewers and land drainage pipes. The system is a curedin-place lining technique using ultra-violet (UV) light to cure the resin, which allows the lining operation to be completed much more quickly than with conventional liners that cure at ambient temperature or by the application of heat.
In addition to applications in the wastewater sector, the UV-cure system is ideally suited to the renovation of railway track drainage where work must be undertaken during very short track possession times. Alongside vehicle-based liner installation and robotic cutting systems, Waterflow has identical equipment mounted on track trolleys that will operate safely on standard gauge railway tracks. Although intended specifically for renovating track drainage for the London Underground and Network Rail, this palletised equipment is also suitable for use in locations with limited vehicle access. The trolleys can be lifted by crane from a bridge or adjacent access point to the tracks below, or be transported across difficult terrain on a suitable offroad vehicle. Installation can be carried out from small access chambers with no excavation or disruption. A novel element of the system is the robotic drilling machine that creates perforations in a lined land drainage or track drainage pipeline. Waterflow's multi-drill robot has an array of six water-cooled diamond drills that operate automatically to perforate the pipeline at predetermined intervals. Conventional replacement of railway track drainage by excavation is slow - averaging about three metres per overnight shift there is also risk of disturbance to the track bed. Traditional lining methods are impractical because of the time taken to set up, cure the liner and clear the track ready for trains to operate.
The issue of perforating the liner and pipe to act as a land drain would still remain unresolved. Waterflow's UV-cure lining system, in combination with the newly developed multi-drill robot for perforation, allows a typical 30 metre length of defective track drain to be completely renovated in just two overnight shifts of about 3.5 hours each, and that includes bringing all the equipment on to site and removing it afterwards. Waterflow Director Roger Kern commented, "We are delighted that the effort we have put into developing this new system has been recognised by the UKSTT.
This Innovation Award is a great encouragement to everyone working on the project, I would especially like to thank the team at Tube Lines for their valued involvement and support over the past two years."
New Thames Water Sewer Renovation Services contract
The Waterflow Group Plc has won a major sewer renovation contract for Thames Water.
The contract will enable us to use our latest cured-inplace pipe lining techniques, UV Light Cured Linings. This environmentally friendly process is used extensively throughout Europe and, as well as the environmental aspects, has many important benefits over old sewer renovation methods. Several renovation projects have already been undertaken for Thames Water using the UV-cure technique, these include some difficult lining installations through sewers located beneath railway tracks.
The contract will operate for three years during this time we expect that this clean, fast, cost-effective pipe rehabilitation process to be fully established in the UK. Waterflow is also using UV-cure lining to renovate track drainage systems on the London Underground rail network.
New office in Vauxhall
The Waterflow Group Plc has established a central London office in Vauxhall.
The Waterflow management team that will be based at the new offices will be handling the management of several new rail contracts. As well as providing a base for the team the office is within easy reach of our main rail client's, Tube Lines and Metronet.
Waterflow's General Manager Rail, Mark Lusher commented "we expect that this will enhance our good working relationship with these two very important customers and enable us perform well with the additional workload". The facilities will be directly linked to our head offices at Heathrow and will be equipped with the latest communications and IT systems. The Waterflow Group Plc now have facilities in four locations around the London area. These locations are at Heathrow, Vauxhall central London, Maidstone and Essex.
Pearpoint Explosion Proof Colour Pan & Tilt CCTV
The Waterflow Group Plc has made a significant investment in the most up-to-date equipment with its purchase of two of the latest explosionproof CCTV inspection systems from Pearpoint.
These pan and tilt, colour, CCTV systems are able to operate in sewers up to 1500mm in diameter and will be used on a major Thames Water sewer survey project. Waterflow's CCTV Manager Adam Wheeler commented "We are very pleased with this latest acquisition, we are also very pleased indeed to be working for Thames Water on this demanding contract. More equipment purchases are planned throughout 2007, this will include more CCTV Camera systems and more vehicle based IT hardware and software".
We are very pleased to report that we have achieved an important milestone, over 100 Waterflow operatives and supervisors have completed the CSCS (Construction Safety Certification Scheme) training.
The Construction Skills Certification Scheme forms an important part of our training programme. We have maintained steady progress during the past year with staff and operatives attending the CSCS courses on a regular basis. This is in line with the company's emphasis on health and safety awareness and competency. The CSCS Training forms part of the comprehensive training programme that all Waterflow staff and operatives receive.
New UV Light Cured Sewer Renovation receives WRc Approval.
The Waterflow Group Plc has now completed the WRc assessments for the installation of its new UV-cured sewer lining system.
WRc Approval for the lining material will follow on completion of final testing of materials. Mr Kevin Woolf, Waterflow's Renovation Manager commented " WRc Approval for our UV light cured lining process is very important to us as it serves to underline our commitment to bring this new technology to the UK, we are very impressed with the performance of the new techniques. The linings are six times stronger than conventional pipe liners, the installation is fast and the finished liners are the best we have seen".
Lining Equipment Operation and Installation Training
All our sewer renovation crews have now completed their training courses on the new UV cured CIPP system.
The courses were held at the German headquarters of manufacturer Prokasro. According to Waterflow's Renovation Manager, Kevin Woolf, There was no language barrier - sewer-speak seems universal! The Waterflow renovation crews have also attended the Brawo Liner training courses in Wolfstein, Western Germany. Waterflow has established expertise in a wide range of pipe lining techniques including ambient-cure polyester lining, Brawo lining, patch repair, hot-cure polyester lining and now the latest UV-cured CIPP system. Kevin Woolf has over twenty years experience in sewer renovation and pipe lining techniques.
The Waterflow Group Plc has recently won two very important safety awards.
The awards received were the RoSPA Silver Award for Occupational Safety for 2006 and the British Safety Council International Safety Award for 2006.
Waterflow's Health & Safety Manager Mr. James Taylor commented "To be eligible for these awards we had to submit our health and safety performance statistics, details of our health and safety managements systems. We also had to demonstrate continuous improvement, both in our management systems and the reduction in accidents and incidents. These awards serve to confirm our solid commitment to health and safety. I am very pleased and proud of our performance to date".
Previous safety performance awards are as follows:
We are committed to maintaining a safe working environment for all our staff and operatives, important and innovative health and safety initiatives are planned for 2007.
