Water loss is a spill-over problem that water service providers seek to control by adopting strategies that will limit both real and apparent loss to targeted levels that are decided upon data provided by reliable databases, the absence of which is a hallmark of many water service providers, especially in developing countries, and this entails resorting to costly strategies to deal with the problem of water loss, especially in its real part. The studies that have examined this issue are devoid of any efforts related to Libya, and this study came to highlight the reality of the real water loss case in Benghazi and the efforts of the city's water and sanitation company to deal with this issue based on their available water supply data and its distribution networks, its consumption characteristics, rates of loss and strategies to reduce this loss. The study concluded that the water and sanitation company in Benghazi not relied on up-to-date data for the water supply hub giving a false indication of whether the city is being supplied with sufficient water whenever linked with the rest of the axes, with the absence of some important operational data for the distribution and consumption axes, such as the methods of measuring the company for the volume of water consumed and the number of customers registered with the company and the workforce of the company. As for the two axes of loss and strategies to deal with it, the database on which the company depends does not provide any quantitative determinants reliable in determining the levels of loss, which the company uses conservative estimate puts loss rates in the same proportion as those recorded for service providers in the United Kingdom, and the only strategy that the water and sanitation company in Benghazi sees was the strategy to renew the water networks with the huge amounts they need to put them into action.
