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.
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....
Report: Energy and utility companies can help preserve water resources
By investing in new technologies and infrastructure, together they can help reduce problems associated with water shortages While both humans and their commercial operations rely on fresh water more than ever, sources of clean water are becoming scarcer. Climate change, droughts, increasing agricultural needs, water pollution, and global economic and population growth all contribute to frequent freshwater supply disruptions.A recent report by Barclays, a transatlantic bank, maintains that the energy industry, a...
