Understanding non-registration in domestic water meters: Implications for meter replacement strategies

摘要: Understanding elements of non-revenue water (NRW) has become more critical in an era where urban a rapidly increasing value. Meter under- and over-registration flows received considerable research attention over the years, but there been limited focus on non-registration, particularly for domestic meters their life cycle. This paper presents empirical estimates non-registration typically installed emphasises that both should be considered any meter replacement assessments associated policies. Economic modelling showed replaced at lower throughput volumes when considering these inaccuracy categories. The key value is it provides methodology determining nonregistration fleet meters.
