  • Estimated Costs to Utilities for Issuing A Boil Water Advisory

    The United States Safe Drinking Water Act (SDWA) has stringent standards in place to ensure the safe distribution of water. However, water quality problems (e.g. water main breaks, elevated turbidity, microbiological non-compliance, etc.) can result in these standards not being met. The consequence of this is often a boil water advisory to inform the public that the water is unsafe to drink. ...

  • Towards a Service Quality Model for Water Utilities

    Regulation of water utilities is often achieved through “yard-stick competition”, where the service quality of monopolistic service providers is compared with peer organisations in the same jurisdiction (Braadbaart, 2007; Lin & Berg, 2008). Regulatory models for water utilities focus on measuring business performance through a series of indicators (Braadbaart, 2007; Byatt, 2013; ...
