Water leakage and pressure management

Mesaj  Gabriela Lupancescu la data de Lun Iul 26, 2010 10:30 pm

We have 2 DMA`s in Timisoara, the first with one entry point and the second one has one entry and one exit point.
The DMA tehnique isd not so common in Romania, as it requieres mannyvalves and water meters.
For example, we have a project to meter a district but we would need a minimum of 5 water meters of rather large diameter (200 - 300).
Another problem is the quantification of water loss because of the large number of personal water meters (the ones that are installed at every
house) wich can not be read in a single day.

We would be curious how you manage you water loss. Are there any tipps you could give us?

Water leakage and pressure management

I can advice you regarding pressure management and DMAs. Athens network is very large. We consider our pressure zones as DMAs, therefore we also have large water meters of diameters up to DN300 as well as flow meters in larger pipes. All water is metered, about 2.000.000 water meters are installed in the network for all purposes (domestic, industrial & commercial uses). Therefore, our DMAs have a large number of water meters as well as important length of pipelines.

Pls specify your questions and we can be in touch for further advice. Besides, pressure management, we also apply advanced pressure management techniques (flow and time modulation) succesfully and we do have impressive results in controlling leakage.
waiting for your answer.
