The Madison Water Utility, located in Wisconsin, US, has commenced a project to upgrade a water main along Droster Road on the City’s east side using Trenchless Technology to avoid digging up the entire street.

The new technique will rehabilitate the existing main, which has been showing signs of deterioration, by inserting a liner through a minor excavation at one end of the main segment. This pilot project will be the first in the state to use the new trenchless method.

Residents will not have their street torn up, and water service will be only minimally interrupted while the work takes place. While the liner is being installed for the entire main between E. Buckeye Road and Starker Avenue, a temporary above-ground water system will supply drinking water.

According to Water Utility Engineer Adam Wiederhoeft, the new water main lining should last at least 50 years, and it is more cost-effective and less intrusive than traditional water main replacement methods. All the liner materials have been certified for use in drinking water systems. The project is expected to be completed in about a month.

Insituform Technologies Ltd Canada President Ken Foster said “Insituform has been installing cured-in-place pipe (CIPP) in Calgary since the mid-1980s and we are pleased to continue to provide high quality pipeline rehabilitation solutions. Our crews remain committed to providing this community with renewed pipelines with minimal disruption.”

Over the next 12 months, Insituform expects to complete approximately 90,000 ft of CIPP rehabilitation on wastewater pipelines ranging from 8 inches to 48 inches in diameter. It is expected that Insituform’s proprietary air inversion steam cure installation method will be used throughout the project. This installation method reduces energy and water usage by approximately 95 per cent.

Thames Water is replacing a section of worn-out, century-old water main that has burst three times in three years between Bicester and Amrosden, located in the UK.

More than 2 km of 12 inch cast-iron pipe between Bicester and Ambrosden will be replaced with tough new plastic pipe.

The major project is part of a £1.5m scheme to cut leakage in Oxfordshire and to minimise the risk of interruptions to the water supply.

Thames Water has been granted special permission from English Nature to work near a community of protected a Great Crested Newts.

Thames Water’s Head of Capital Delivery Lawrence Gosden said, “This is a must-do job to improve the water supply network over the long term for our customers in Oxfordshire.

“We’d ask people to bear with us in the knowledge that the purpose of this project is to reduce the number of disruptive burst and leaky pipes in the area by replacing creaky old cast-iron mains with tough, new plastic ones less prone to breaks and leaks.

There will be no road closures in place although there will be some traffic management along the route of the pipe on the A41 from Bicester, along Ploughey Road and into Ambrosden Village.

Work is set to commence 6 October and will be ongoing until February 2012.

By offering a single service agreement for pipeline maintenance and remediation, the benefits of non-destructive inspection coupled with non-destructive repairs can rehabilitate piping systems without the added costs commonly associated to traditional ‘poke and hope’ methods.

Using advance locating devices to crawl and inspect piping as long as 1,000 ft, damages and blockages can be identified accurately and remedied quickly using line-in-place technology up to 24 inches in diameter. The ease and accuracy of both methods prevent costly project overruns and unneeded roadway disturbances commonly found with traditional remediation projects.

Business Development Manager of Jamko Technical Solutions Karl Schlifke said, “From a new build to regular maintenance to remediation projects, the strategic alliance will deliver experienced field technicians and advanced pipeline technology to customers throughout New York State and the New England region.”

The new structure will eventually replace the town’s existing pumping station in Greta Grove. At around twice the size, it will play a vital role protecting the environment and helping prevent the problem of sewer flooding which occasionally affects some local homes.

Project manager Simon Povey said engineers had a lot of essential work to do but had the community’s best interests at heart.

“As well as working in the car park, the coming weeks will also see some work under Keswick streets. We’ve talked to a lot of people about the best way to do this and now have a program that avoids the run-up to Christmas and a number of important local events.

“After the new year we will be back to install and upgrade some sewer pipes and we hope to finish this by Easter,” Mr Povey said.

This project will take place on Chicago Avenue from Pembroke Road to Charles Street. Traffic patterns will be altered on Chicago Avenue throughout construction, and signs will be in place directing motorists to alternate routes.

This project will utilise an innovative Trenchless Technology consisting of cured-in-place thermosetting resin pipe that is installed inside the existing water main. The process creates a structurally sound and flexible pipe, therefore eliminating corrosion and greatly reducing future water main failures.

The use of Trenchless Technology has many advantages over conventional dig and replace methods. These include a significant reduction in pavement replacement, property restoration and other construction-related issues such as noise and dust.

Additional advantages of this Trenchless Technology include rapid installation and minimal future disruptions caused by water main breaks. In addition, the life of the existing water main is extended by more than 50 years.

The work will involve the replacement of approximately 110 km of water mains to improve the quality, reliability and flexibility of water supply, while also reducing leakage.

The work will take place in two phases, with one phase focusing on the area around Moneymore, including work taking place in the Loup and Orritor areas.

The second phase will centre on the rest of the Cookstown District, with work taking place in areas such as the settlements of Kingsmills, Dunnamore and The Rock.

Wachs Water Services has been awarded a $US9.4 million contract extension to continue supporting the City of Atlanta, Georgia, US, in their efforts to assess, test and survey thousands of valves and fire hydrants throughout their water network.

One of the largest water infrastructure projects of its kind in the United States, Wachs Water Services is helping to improve and rehabilitate vital water distribution system assets and control points for the City of Atlanta as part of a joint venture with Brindley Pieters and Associates.

The ongoing program has accomplished several water system improvements to date, including achieving a high degree of water main valve operability that has set industry standards for large urban cities.

Wachs Water Services President Cliff Wilson said “Managing an aging water network requires a results-driven approach that achieves both immediate system improvements and long-term sustainability.”

The program in Atlanta is focused on improving water main valve and fire hydrant operability, enabling the utility to better respond to water main breaks, achieve a high-level of operational control of the water network, and pinpoint repair and replacement of water distribution assets more effectively.

Working with the Atlanta Department of Watershed Management, services provided by the joint venture include asset location, operational condition assessment, and GPS location mapping of critical water assets.

We expect to maintain a productive relationship with Coninstrugas and yourselves and hope that they and you share this desire. Should you have any questions regarding the foregoing, please contact me.

Sincerely,
