* Mean Zonal Compliance

** Serviceability is the capacity of a system of assets to deliver a reference level of service to customers and to the environment now and into the future. Serviceability is deemed to be stable when the assessment of trends in a defined set of service and asset performance indicators demonstrates that service is in line with the reference level of service and, by inference, is likely to remain so into the future.
