Evaluation of the effects of non-revenue water on water security in Ondo State, Nigeria

Abstract

The provision of safe drinking water is a crucial service that gen-erates revenue for water utilities to fund their operations. The an-nual amount of water lost is a crucial indicator for evaluating how effectively water is supplied and distributed. According to the us-age of a deterministic simulation model on public water supply var-iables, the volume of non-revenue water (NRW) and its cost conse-quences have further developed a complicated system for the availability, distribution, and affordability of the utility. Annual wa-ter accessed (AWA) was negatively impacted by the steady annual increase in public water supply (AWS) from 8.0 * 106 m3 to 13.4 * 106 m3, with R2 = 0.096, and annual water loss (AWL) was signifi-cantly impacted with R2 = 0.99. This result suggests that the public water supply plays a role in water loss, which primarily occurs through leaks and bursts. As a result, Akure's expected annual vol-ume and revenue water costs (NRW) are 6 million m3 and 15.6 mil-lion USD, respectively. A thorough investigation reveals that the annual money lost might be utilized to fund health and education programs for eight months. Therefore, it is predicted that the diffi-culty of determining safe drinking might be reduced by 30% if the rainwater is effectively harnessed in Ondo State, Nigeria
