Usually water utilities provide their services under natural monopoly, with few incentives to become efficient, therefore affecting customers in the form of expensive tariffs. Hence, it is extremely important to find out the sources of inefficiency. The present study aims to identify the most efficient water utility groups in Brazil. For this purpose, a robust non-parametric method was applied. The results show that the utilities that provide both drinking water and wastewater services, the local utilities, and the utilities with private participation are more efficient. Furthermore, this study proved that the utilities were more efficient before the regulatory framework had been implemented.

Mind Set

Protection of the water environment has become a modern socio economic issue in which the sociological pressures for a healthy water environment must be balanced with affordability. Reconciliation of these aspects requires clear political thinking and rigorous methodologies. It also requires a shift in mind-set which considers members of the public as customers. Water utilities are the major users of the water environment and potentially its greatest threat – so good delivery of water services is very important. The presentation addresses the topic through the experience of Anglian Water, a privatised water utility serving Eastern England.

Water Behavior

Provision of safe drinking water by water utilities is challenged by disturbances to water quality that have become increasingly frequent due to global changes and anthropogenic impacts. Many water utilities are turning to adaptable and flexible strategies to allow for resilient management of drinking water supplies. The success of resilience-based management depends on, and is enabled by, positive relationships with the public. To understand how relationships between managers and communities spill over to in-home drinking water behavior, we examined the role of trust, risk perceptions, salience of drinking water, and water quality evaluations in the choice of in-home drinking water sources for a population in Roanoke Virginia. Using survey data, our study characterized patterns of in-home drinking water behavior and explored related perceptions to determine if residents’ perceptions of their water and the municipal water utility could be intuited from this behavior. We characterized drinking water behavior using a hierarchical cluster analysis and highlighted the importance of studying a range of drinking water patterns. Through analyses of variance, we found that people who drink more tap water have higher trust in their water managers, evaluate water quality more favorably, have lower risk perceptions, and pay less attention to changes in their tap water. Utility managers may gauge information about aspects of their relationships with communities by examining drinking water behavior, which can be used to inform their future interactions with the public, with the goal of increasing resilience and adaptability to external water supply threats.

The frequent analysis of the 2-methylisoborneol (2-MIB)-generating algae, Pseudanabaena sp., for predicting odor occurrence in drinking water sources is a major challenge for many drinking water utilities. This study aims...
