“…Variables of Number of Connection and Consumption Quantity has a negative linear relationship with the Non-Revenue Water. This result was consistent with the study done by Adams & LutzLey (2012), Aubuchon & Roberson (2012) and Murrar (2017). Meanwhile, the variable of Production Quantity has a positive linear relationship with the Non-Revenue Water.…”

“…Aubuchon & Roberson (2012) stated that the increase of water consumption with increasing total profit, may provide the budget to recover any damage or leakage and can reduce the Non-Revenue Water Ratio by investing in maintenance cost. Murrar (2017) found that there is a negative relationship between consumption volume on Non-Revenue Water per connection. This indicates that more water consumption will reduce the Non-Revenue Water.…”

“…Moreover, Korevaar et al (2013) also mentioned that the number of connections can lead to the increase of Non-Revenue Water. A regression analysis that was carried out by Murrar (2017) indicated that the more connection in the network, the more increasing the water loss is. This is because when the number of connection increases, the probability of water out through the intersection will also increase.…”

“…Liemberger (2010) concluded that increasing water production is a key strategy in reducing Non-Revenue Water. Murrar (2017) mentioned that Non-Revenue Water in the year 2015 decreased from 50% in the year 2003 to 23% due to increase in production quantity from 12 in the year 2003 to 91 litres per person per day in the year 2015. This indicates that there is a negative relationship between production quantity and Non-Revenue Water.…”

Water is one of the most essential needs in human daily life. Water losses or Non-Revenue Water (NRW) refers to the treated water that has been produced from water plant which did not reach to the customer. This waste of water has caused the company to suffer losses and hence, burdens the people with increasing water tariff. Moreover, it becomes one of the challenges for commercial water system management because the water company must fulfil the demand from the society which keep increasing day by day. In addition, the demand for water is increasing, as the population is growing. Despite having the rainfall throughout the year in Malaysia, many cities are experiencing water shortage and frequent water supply disruptions. Therefore, efficient management of water distribution is required to minimise the water losses and to make sure the sustainability of water reserve for a long period. This study focuses on identifying the significant factors that influence the Non-Revenue Water and modelling the data using Multiple Linear Regression Model. The sample size used in this study were 212 observations and the variables involved were Length of Connection, Number of Connection, Production Quantity, Consumption Quantity and Non-Revenue Water. It is found that the variables of Number of Connection, Consumption Quantity and Production Quantity were significant to Non-Revenue Water whereas the variable of Length of Connection was not significant. It is hoped that the result from this study can be used by the water authority company in improving the water distribution and thus reduce water losses and cost.

Non-Revenue water (NRW) refers to water produced and lost before reaching consumers. The summary focuses on the importance of reducing Non-Revenue water (NRW), as it increases water availability and the revenues of drinking water. This reduction is achieved when we install the flow meters and water pressure devices at water sources or inlets and exits of isolated areas. We can calculate the amount of water supplied to the area, comparing it with the calculated amount and determining the volume of water not subject to accounting. To solve this, actions like leak detection to determine the location of hidden connections and installation of effective water meters. Supervisory Control and Data Access (SCADA) systems have a role in water management, providing control and real-time monitoring, early problem detection, improved efficiency, and support decision making. When we use Supervisory Control and Data Access (SCADA) technology, we can reduce water losses, ensure reliable water supplies, and contribute to city water management practices. Reducing inaccurate billing or theft can increase revenue. Also, reducing physical/real losses, like leakages or inefficient distribution systems, engage water and wastewater companies to postpone investment in water resource development. To achieve the challenge, cooperation between departments such as network operations, hydraulic analysis, and geographic information systems is required. The commercial sector is important to evaluate and identify the different components that contribute to reducing water loss (NRW).

Studies investigating the relationship between size and performance of water service providers are abundant. Yet, this relationship has not been fully addressed in Palestinian water sector, particularly, after the issuance of water law 2014 which calls for merging water providers into large regional utilities. This research evaluates the significant effect of the size of Palestinian water service providers on non-revenue water, staff productivity, collection efficiency, average consumption, average price, operating and maintenance cost, working ratio, and gross profit. The multivariate analysis shows that there are significant differences in working ratio, non-revenue water, staff productivity, average price, and gross profit based on the size. On the other side, no significant differences have been found in average daily consumption, operating and maintenance cost per unit, and collection efficiency based on those providers' size. The small service providers perform better in non-revenue water, staff productivity, and collection efficiency; wherein, large service providers are more profitable than small service providers. Implications of these findings by conducting further studies will add the value for better merging of the Palestinian water providers and the reforming process.
