This study examines the characteristics of municipalities owning water utilities that took advantage of incentives provided by the Japanese government to consolidate. We find that economies of scale and government transfers were some of the main factors leading to consolidation of government services. This is expected given the Central Government's efforts to equalize public service levels, and the large cost savings available to municipal level water monopolies.
Water is the most valuable asset on earth, which determines to a significant extent the development of life in all corners of the world. 95% of the amount of water on earth is chemically bound in rocks making it impossible to utilize and be part of the hydrological cycle. Of the remaining 5%, 97% is saline found in oceans and seas, while the remaining 3% is distributed: • 2,37% in polar ice and glaciers • 0,6% in deep underground aquifers, which are not exploitable • and finally 0,03% in...
3 Water Utilities that Lowered their Arsenic Levels with AdEdge
Finding an appropriate solution to address arsenic in raw water can be challenging for utilities. Studies have shown that when ingested in high concentrations, it is linked to cancer in the skin, lungs, bladder and kidney, and can cause significant skin changes, such as thickening and pigmentation, as well as other health issues. For this reason, the U.S. Environmental Protection Agency (EPA) has a maximum contaminant level standard of 0.01 mg/L. Throughout the country, municipalities are looking for ways to...
Governance, strategy and efficiency of water utilities: the Italian case
The determinants of the performance of water utilities are a topical issue worldwide. This paper analyzes the relationship between efficiency and corporate governance in Italian water utilities, measured through data envelopment analysis. Using an M-quantile regression model, efficiency estimations are ranked considering relevant governance (board size and composition; firm size) and strategy features (membership of a corporate group; provision of wholesale services) in order to provide decision-makers with...
Protective coatings for underground utility concrete structures
As our cities and municipalities grow older, the utility and wastewater infrastructure and corrosion preventive program for underground asset protection are aging with them. Municipalities and Utility Companies are struggling to handle rehabilitation measures and effective corrosion prevention programs to deal with prolonging the life of their buried assets. More municipalities are in the process of undertaking rehabilitation projects to restore underground structures and protect them against further corrosion....
Resilience-based water main rehabilitation planning in a multi-hazard context
Due to aging beyond the intended design life, many water mains in the USA are currently deteriorated resulting in an increasing number of failures which challenge water utilities with diminished supply reliabilities, loss of treated water, and numerous other societal issues. Water pipeline systems serving regions that are naturally vulnerable to external hazards, such as earthquakes, pose additional challenges. Numerous vulnerabilities such as these must be congruently analyzed for optimal capital improvement...
