“…6 Analysis of the performance of Brazilian water supply concessionary companies in the period between 2002 and 2004, showed that public companies were more efficient. 26 A study analyzing the effect of governance on the dynamic efficiency of the water companies also found no robust gain in efficiency following the privatization of utilities. 17 When public companies were analyzed, there was more likelihood of households being connected to water and sewerage networks in municipalities served by government agencies.…”

Objective: to describe the characteristics of Brazilian sanitation utilities and municipalities according to the water supply system fluoridation situation. Methods: this was an ecological study using data from the National Survey of Basic Sanitation 2008, the Demographic Census 2010 and the Atlas of Human Development 2010. Results: of the 5,565 Brazilian municipalities, 60% had a fluoridation service; there was variation in fluoridation provision depending on the characteristics of the service providers and the municipality; the greater the coverage of water supply and sewerage and the higher the level of human development, the greater the provision of fluoridation (p<0.001); fluoridation provision was higher in municipalities where the sanitation utilities were mixed-capital companies (75%) and lower when the companies were private (27%) and also when the service was provided only by the municipal government (40%). Conclusion: there was an important dependence relationship between the characteristics of the companies and the provision of water fluoridation in Brazilian municipalities.

“…Most previous studies have examined privatization in the US and UK contexts and provided mixed empirical findings (Bel and Warner ). Some studies have found that costs of water supply services are significantly lower under direct public delivery than under private delivery (e.g., Mann and Mikesell ; Bruggink ; Lynk ; Bhattacharyya et al ; Souza et al ), whereas others have suggested the opposite effect (e.g., Morgan ; Crain and Zardkoohi ; Raffie et al ) or have found no significant difference between the two institutional arrangements with respect to cost savings (e.g., Feigenbaum and Teeples ; Fox and Hofler ; Teeples and Glyer ; Byrnes ; Bhattacharyya et al ; Ashton 2000a, 2000b; Saal and Parker ).…”

Effects of institutional arrangements in local water supply services in Korea

In Korea, local governments are primarily responsible for providing water supply services to citizens. Since 2004, 15 local governments have contracted this service to the Korean Water Resources Corporation (K-Water). This paper examines the effects of the two different institutional arrangements -direct public delivery versus contracting out to K-Water -on cost savings and productivity. To do so, it employs a hybrid cost function approach and uses the panel data covering the nine years from 2000 to 2008 in local governments. Empirical findings show mixed evidence on the effects of the two institutional arrangements on cost savings and productivity gains. Water supply costs are significantly lower under contracting out than under direct public delivery. However, there are no significant differences in productivity gains between the two institutional arrangements. Local water supply systems need to further reduce the average water supply costs through increasing their size and magnitude. JEL classification: H44, R50, L95, Q25

“…The difficulty in providing public sanitation services, in terms of access and quality, are governance challenges to be overcome in the next two decades, as highlighted by several authors [ 9 , 16 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. Studies in the field reveal a growing preoccupation in better understanding the causes and consequences of efficiency problems in the use of infrastructure, human, and financial resources in this sector, in order to boost development and competitiveness between agencies and sanitation companies.…”

This study aims to evaluate the level of technical efficiency of companies that perform the integrated management of basic sanitation in Brazilian municipalities. A Multiple Data Envelopment Analysis (M-DEA) model was applied to estimate the performance of water supply and sewage services in 1628 municipalities covering more than 56% of the Brazilian population, identifying the factors that most influence the efficiency of the sector in the years 2008 and 2016. The M-DEA methodology is an extension of Data Envelopment Analysis (DEA) with multiple DEA executions considering all combinations of inputs and outputs to calculate efficiency scores. The methodology reduces possible biases in the selection of resources and products of the model, ability to support decision-making in favor of improvements in the sector′s efficiency based on national regulatory framework. The analyses show that the companies analyzed can increase their operating results and attendance coverage by more than 60%, given the current levels of infrastructure, human and financial resources in the sector. Based on the simulation of potential efficiency gains in Brazilian basic sanitation companies, the estimates show that the coverage of the population with access to sanitary sewage would go from the current 59.9% to 76.5%. The evidence found provides indications to subsidize sanitation management in the country at the micro-analytical level, enabling a better competitive position in the sector for the integrated management of basic sanitation and its universalization in Brazil.
