Description

Pavements Many water utilities operate their pipe networks as an open system where water is fed from more than one Water Treatment Plant (WTP) into an inter-connected pipe network. Generally, NRW management in an open system is undertaken in a passive manner where NRW reduction activities are initiated only when the loss becomes visible or is reported. A more effective approach is to move towards Active NRW Management where dedicated teams are established and sent out to look for water losses or other causes of NRW such as reservoir overflows, in main pipes, distribution networks up to the customer, inaccurate meter reading, and illegal connections. Active NRW Management is more cost effective when using zones to measure the NRW, where the system as a whole is divided into a series of smaller sub-systems for which NRW can be calculated individually. These smaller sub-systems, often referred to as District Meter Areas (DMAs) should be hydraulically isolated so that dedicated team would be able to calculate the volume of water lost within the DMA. When a supply system is divided into smaller more manageable areas, the utility can better target NRW reduction activities, isolate water quality problems, and better manage overall system pressure to allow for 24/7 water supply throughout the network. These include the analysis of minimum night time flows (MNFs) into District Metered Areas (DMAs), as well as the results of active leakage control surveys carried out in District Metered Areas. The author seek to emphasize that from his professional experience at Prishtina Regional Water Utility, the issue regarding NWR, in most of the Water companies in Kosovo and or in Albania, should focus on one of aggressive, system-wide metering from sources, to production and storage reservoir meters, through district metering areas, and finally to customer meters. Therefore, this paper will contain network zoning and design of DMA, active control of leakages, and achieved results in water loss reduction in metered areas. The findings, and interpretations, expressed in this paper are entirely those of the author.
