Using Alternative Methods in Greenland - Qaqortoq, Greenland - Case Study
In 2012, Leif Koch A/S had the honor of performing leakage detection as well as being witness to the repairing process. At the time, Nukissiorfiit Qaqortoq lost 5-7 m3 of water each day on their district heating plant. Unfortunately, nature of the pipes made it impossible to find the leaks without the use of alternative methods, which is why the supply company decided to contact Leif Koch A/S. ...

Adapting the IWA water balance to intermittent water supply and flat-rate tariffs without customer metering
The International Water Association water balance is an approach applied worldwide for determining and analysing water losses in water distribution systems (WDS) up to the point of customer metering. Thus, water losses occurring ‘before’ a customer meter are at the expenses of the water utility while water lost or wasted ‘after’ the meter is paid for by the customer. This applies to systems ...

A mathematical model to evaluate apparent losses due to meter under-registration in intermittent water distribution networks
Apparent losses consist of water volume drawn from the network, consumed by users but not paid for. Those due to water meter under-registration were evaluated by means of a mathematical model able to analyse the complexity of intermittent supply systems with private tanks. This supply scheme is very common in the Mediterranean area where unexpected water shortage often happens and intermittent ...

Assessment of domestic consumption in intermittent water supply networks: case study of Puerto Ayora (Galápagos Islands)
Intermittent water distribution systems are a stark reality in developing countries. Puerto Ayora, the centre of tourism of the Galápagos Archipelago, is not an exception, with its population and tourists suffering from scarce water resources. However, the extreme per capita consumptions, well above those in 24/7 supply situations in many other countries, contradict the (sense of) scarcity. ...

Counting the Drops: Leak Detection and Auditing Methods for Property Managers
Leaks are never good, whether it’s a leaky boat or a leaky pipe system. Even advanced water utility systems can experience water loses ranging from 10 – 40%, with these losses being proportional to the population of the urban area serviced by the water distribution system. Large cities like New York, Chicago, and Los Angeles are vulnerable to staggering amounts of water loss in ...

How to avoid system downtime when installing flow meters
FPI Mag installed in pipe. Water and wastewater utilities rely on accurate flow measurement for important process controls. These may include recycle streams, chemical dosing systems, and other operational functions. In addition, regulators require utilities to measure certain flows, such as treatment plant influent and effluent and potable water pumping. Accurate flow measurement is also ...

Israel/Haifa: Cutting water loss by more than half in a rigorous process - Case Study
Introduction Haifa is Israel’s third-largest city with a population of over 250,000. It is in the very north of Israel, close to the border to Lebanon and beautifully situated on the shores of the Mediterranean Sea. Mei Carmel is a public corporation founded in 2010 as a spin-off from the municipal government with the aim to improving the public service level to the residents of Haifa. Mei ...

Water level sensors help Australian irrigation
Irrigation management is serious business in Australia especially within the Murray-Darling Basin, a 1,000,000 square kilometer watershed that is home to Australia’s most productive agricultural land. The basin’s 23 rivers have some of the lowest and most variable flows in the world. A massive system of dams, lakes and canals stores water from mountain snowmelt and seasonal ...

Hole Dug, Leak Found - City Of Ottawa Entrusts Smartball Platform To Look For Leaks In Tranmsission Main
When your inspection task is to survey a critical pipeline for leaks, nothing is more satisfying than trusting your technology to predict the leak location and then standing by as the client excavates the area to find a flow of water within one meter of exactly where you said it would be. The above-described "leak-where-predicted" recently happened with the City of Ottawa, when Pure Technologies ...
