Experiences in DMA redesign at the Water Board of

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. This paper reviews the experiences gained at the Water Board of Lemesos in striving to achieve lower levels of leakage by DMA resizing and subsequently applying a pressure reduction programme. An account of the work carried out in redesigning DMAs is given as well as the results obtained in further reducing leakage from the distribution system by pressure reduction and control to economically acceptable levels and to maintaining these levels through the adoption of an effective active leakage management strategy
