Data analysis was performed in a quantitative and qualitativemanner using descriptive statistics and thematic analysis respectively.Findings of thestudy revealed that, the unbilled authorized consumption influences highly NRW.Besides,linearrelationshipexistsbetweenmetered,unmeteredunbilledauthorizedconsumption and level of NRW.Study findings alsorevealedthat, billing system errorshashighinfluenceonNRW. Influence of fourtechnicalerrorsonNRWwasidentifiednamely, age of infrastructure, leakages, bursts, and metering inaccuracy. Further, resultsindicatedthat,socialdynamicsfactors,whichinfluencedNRW,includewatertheft,corruption, high water tariffs, and intermittent water supply. Multiple linear regressionanalysisrevealedthat,unbilledauthorizedconsumption,billingsystemandtechnicalerrors, and social dynamics factors have significant relationship with level of NRW. Thesefactors explain 19% increase of the level of NRW. The study recommends that, inorder to reduce unbilled authorized consumption, installation of standard meter designshould be conducted align with repair of meter registration inaccuracies.
