“…Based on calculation method, all consumption components as well as losses are being identified in one standardized form in this water balance. Clearly defined water balance represents a first step in the process of evaluation of non revenue water, water losses and leakage management in water supply systems [4].…”

“…They actually represent the minimum real losses level that can be achieved, utilizing appropriate strategies (Figure 3) [28]. UARL measured in lt/day can be estimated using the empirical expression (2) [29], where, P is the average operating pressure (m), L m is the mains total length (km), N c is the number of service connections and L p is their total length (km) (up to the user's meter).

This paper presents the basic principles for the integration of the water and carbon footprints cost into the resource and environmental costs respectively, taking the suggestions set by the Water Framework Directive (WFD) 2000/60/EC one step forward. WFD states that full water cost recovery (FWCR) should be based on the estimation of the three sub-costs related: direct; environmental; and resource cost. It also strongly suggests the EU Member States develop and apply effective water pricing policies to achieve FWCR. These policies must be socially just to avoid any social injustice phenomena. This is a very delicate task to handle, especially within the fragile economic conditions that the EU is facing today. Water losses play a crucial role for the FWC estimation. Water losses should not be neglected since they are one of the major "water uses" in any water supply network. A methodology is suggested to reduce water losses and the related Non Revenue Water (NRW) index. An Expert Decision Support System is proposed to assess the FWC incorporating the Water and Carbon Footprint costs.

“…Selected performance indicators were also estimated and reported. The second modified WB is based on the IWA International Standard WB introduced by Lambert et al [5] and incorporates the first proposed modification by McKenzie et al [6]. It also introduces "Minimum Charge Difference" (Figure 2) NRW compared to NRW).…”

Abstract:Water use efficiency is a crucial issue in drinking water utilities as it is connected to environmental and economic consequences. WATenERgy CYCLE project aims at developing a methodological approach towards efficient and effective transnational water and energy resources management in the Balkan-Mediterranean area. The paper presents the results of performance evaluation of the water supply systems of the water utilities involved in the project, both at local and national level. The methodology used in the water balance and performance indicators as well as data on the operational status of the water supply systems. The results showed that Non-Revenue Water is one of the major problems addressed.
