Instead of waiting for mains to arrive, Fluence can provide flexible, modular treatment to get your project going As a global trend toward urbanization continues, population growth hotspots in the United States have been concentrated in the South and West, with many suburbs and exurbs now experiencing rapid growth that outpaces local infrastructure planning. Recent Census Bureau estimates show ...
Almost everyone knows about the challenges the telecoms industry had with the “last mile” efforts made on land years ago to connect the main trunk fiber broadband network into the home. Enabling the last mile meant that by placing a wireless modem in the home we witnessed profound changes in life as we had known it. ...

Introduction Three million litres per day of drinking water were leaking from a 16-inch cast iron pipe buried 2.5 metres beneath Guildford Street, next to the historic Great Ormond Street Hospital in central London, and it was discovered amid an intensive hunt for leaks across the capital’s trunk main network. Thames Water’s pipe network stretches ...
On the morning of Saturday 27th May 2017, an 8” cast Iron trunk main carrying water from a reservoir to the area of Sea Mills burst. ...
An initial location on an 18” Cast Iron trunk main was identified from Longwood Service Reservoir feeding four large DMAs. ...
Introduction Locating leaks on large diameter water mains can be very difficult due to poor sound propagation and increased distances between fittings that can be used to perform correlations from. ...
Trunk mains connect the water works or reservoir with the distribution network. ...
Based on the field evidence and simulation results, the leak-before-break approach might be applicable in CI pipes to avoid severe consequences of trunk main bursts. ...
This geographical landscape creates a number of operational challenges, including: A large number of different pressure zones; Long sections of trunk main; and Long distances for maintenance staff to drive to reach the extremities of the network. ...
This paper presents predictive discolouration modelling and subsequent field trial validation for a cast iron trunk main network. This enabled a UK water company to propose an ‘operational flow conditioning’ maintenance plan that reduces discolouration risk, improves network resilience and asset condition and yet does not require the ...
To tackle the issue, this paper proposes a new concept for rehabilitation and expansion of a water distribution network while ensuring cost-effectiveness and adequate water pressure. The main framework of the pipe network is formulated based on the concept of a ‘trunk/limb mains reinforced pipe system’. Reinforcement of ...
This paper describes an enhanced concept for determining the right time and place for maintenance works (in this case rehabilitation and renewal), within the scope of a risk-based maintenance strategy for trunk mains, including a technical and economic risk assessment. The risks considered include damage caused by pipe failure (main burst) like ...
The Aquasscan TM Successfully locates leaks at distances over 1KM in Sydney. The Gutermann Aquascan (Trunk Main) correlator provided a series of high performance correlations in trials performed in Sydney, Australia. Sydney Water provided a 1.2 KM of 600mm OD Steel trunk main for a series of tests to be performed to evaluate ...
A Thermoluminescent Dosimetry (TLD) card was placed on the main trunk of the body of the accompanying person(s), where the maximum dose was probable. ...
Kingsborough used the new Vermeer BC2100XL brush chipper for the job, one that is capable of processing whole trees that have limbs and branches attached to the main trunk. The BC2100XL is built for production and features a 21-inch capacity and the largest infeed table in its class, allowing for smooth material feeding. ...
