Reducing Non-Revenue Water

Abstract

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).
