Effective Pressure Management of District Metered Areas The paper highlights the growing global water crisis caused by rapid population growth, urbanization, and climate change, which is widening the gap between water supply and demand. It discusses how water utilities, particularly the Water Board of Lemesos in Cyprus, are addressing these challenges. Despite efficient management, the

Bambos Charalambous, Stuart Hamilton Have you ever wondered what you do with the water balance after the various components have been calculated? Or how you can use the numbers to work out an investment strategy and an action plan and how to prioritise your actions in order to get the best return on your investment?

“Challenges of Water Scarcity and Intermittent Supply: Lessons from the Water Board of Lemesos, Cyprus” The world’s population is increasing at a tremendous rate, the world’s renewable water resources are reducing rapidly, the gap between supply and demand is widening with urbanisation and climate change making it even wider. This paper reviews how the Water

Through the Intergration of Technological Changes and Strategic Planing The Water Board of Lemesos (Water Board) identified the need for the development and implementation of a Supervisory Control and Data Acquisition (SCADA) system, which would provide real time control and management of the water production and storage and of the distribution network.

Water Board of Lemesos Water Losses are made up of the Apparent and Real Losses. The Water Board of Lemesos considers that the reduction of Apparent Losses is as equally important as the reduction of Real Losses. This paper provides a detailed account of two studies that were carried out at the Water Board of

-at the Water Board of Lemesos, Cyprus- It is evident that water is a limited resource in arid and semi-arid regions of the world, a situation that has highlighted, among other things, the need to reduce leakage from urban water distribution systems to levels that are considered economically acceptable.

Effective Pressure Management of District Metered Areas This paper reviews global practices in pressure management and optimisation as leakage control strategies to reduce water losses in distribution networks. It outlines the methodology and experiences of the Water Board of Lemesos in lowering leakage to economically acceptable levels using advanced pressure control techniques like two-point control

It stresses that IWS undermines network performance, causing leakage, contamination risks, inequitable distribution, high coping costs, and revenue loss. The proposed transition approach is built around three core components: ensuring reliable water supply at the production and transmission level, improving distribution network efficiency by minimizing leakage, and promoting equitable and efficient water use among consumers. 

-Bambos Charalambous, Roland Liemberger- The paper highlights that intermittent water supply (IWS), though often introduced as a response to shortages or leakage, causes significant long-term damage to water distribution networks. It leads to increased leakage, water wastage, inequitable distribution, contamination risks, higher coping costs for consumers, and financial burdens on utilities. While IWS may appear
