Grupul de specialisti in managementul pierderilor de apa din cadrul Asociatiei Internationale a Apei (WLSG – IWA) si-a propus sa organizeze o serie de webinarii live gratuite catre cei interesati de tema Water Loss (pierderi de apa).

Cu acesta ocazie in fiecare zi de luni, miercuri si vineri au loc webinarii live pe diferite teme si cu diferiti prezentatori.

Webinariile au avantajul de a crea o dezbatere pe o anumita tema, de a intreba experti despre anumite situatii intalnite.

Pana acum au fost sustinute webinarii legate de Managementul presiunii, Proiecte NRW, Balanta apei (webinar sustinut de dl. prof. Alexandru Aldea din Romania).

 

Webinariile sunt postate apoi pe platforma IWA de Youtube:

 

Advanced Pressure Management (Gary Wyeth)

An introduction to pressure management, looking at the four pillars of real losses and how pressures can affect leakage volumes and pipe burst frequencies. Then the video looks at Pressure reducing valves and how a basic PRV functions, leading on to timers and modulation.

 

Financing NRW Projects – David Ehrhardt

 

Challenges for establishing the water balance – Alex Aldea

 

Quite often when someone sees or hears for the first time about the water balance, they tend to think that it is something that requires no more than basic arithmetic in order to calculate it. However, at the very first attempt to calculate a water balance in a real situation, pretty much everyone changes their opinion drastically. Further challenges await the person who starts calculating the water balance in countries or regions when there is very little knowledge about the IWA water balance and where usually there is very little data available. This kind of situation poses enough challenges even for a seasoned expert, so a beginner could be very easily overwhelmed or could make mistakes without realizing it. This webinar will tackle the most common mistakes that can be made under these circumstances with examples regarding every water balance component using WB-EasyCalc software. Several examples will be presented when the scarcity and unreliability of the data was partially mitigated by ultrasonic flow measurements.

 

Back to Basics – Roland Liemberger

 

It is already 20 years that the first edition of the IWA Manual of Best Practice, ‘Performance Indicators for Water Supply Systems’ had been published. It included the (then) new standardized water balance and water loss performance indicators. Since then Roland Liemberger has analyzed the NRW situation of water utilities around the world and has provided training to hundreds of engineers in many different countries. In this webinar Roland will explain the basics to those which are relatively new to the topic but also offer a few thoughts and tricks to the more advanced NRW engineer.

Leakage management in times of drought – Carlos Berenhauser

The webinar will concentrate on the use of night time pressure management, as the main action when facing a drought, and the execution of performance based contracts before and after a drought. It will also discuss how facing a drought can show how so much more can be done, with examples from Sao Paulo.

 

Managing repair quality – Jo Parker

 

 

Brief:
It doesn’t matter how many leaks are located, until they are repaired the leakage levels will not be affected. Repairing a leak can cost several times more than locating it and all too often a poor repair can lead to future leaks. In this webinar Jo Parker will draw on her worldwide experience to remind people of the fundamentals of making a good repair as well as introducing some new approaches which can speed up the repair and reduce disruption.
