“…While incorporating user perceptions into the tariff model provides valuable insights, it is crucial to acknowledge the potential limitations and biases associated with user-reported data. Respondents may overestimate their willingness to pay or inaccurately report their actual water usage patterns [94]. To mitigate these biases, a stratified random sampling method was employed to ensure a representative sample of the population, and the survey responses were cross validated with actual billing data where possible.…”

This study addresses the financial sustainability challenge of integrated watershed management (IWM) in regions with inadequate water service tariffs. A novel water service tariff model is proposed, incorporating supply costs, water loss reduction investments, and IWM expenses informed by user perceptions. The model is applied to an intermediate Andean city in southern Ecuador, where the current tariff impedes the financial viability of the water utility, reflecting a regional trend. The results indicate a necessary tariff increase exceeding 100% to cover the costs and support IWM. The economic value of watershed environmental services (WES) were estimated at USD 1,505,530.64 per year. This value translates to an average water consumption of 20 m3/user/month, equivalent to a WES of USD 2.60 per month. Despite the users’ willingness to pay falling below the estimated economic value of WES, there is a clear need for implementing incentive programs to promote water conservation and policy adjustments that favor the financial sustainability of water supply companies in developing countries.

The technical efficiency of water companies plays a crucial role in ensuring the reliable and sustainable delivery of clean and safe drinking water. It also influences the effective management of water and wastewater services. Services of this kind, usually provided by a monopoly supplier, offer operators no market incentives to innovate, or improve their efficiency. So, the mission of the regulatory institutions is to simulate a competitive environment. The main aim of this contribution is to use Network Data Envelopment Analysis (N-DEA) to assess and benchmark the technical efficiency of 14 water and wastewater companies offering their services in Slovakia from 2019 - 2021. The methodology of N-DEA allows us to assess the activity’s cost and delivery efficiency, and its overall technical efficiency. We show that full cost efficiency was achieved by two small and one large water companies operating in different regions. Three of the largest suppliers of water and wastewater services and one small company achieved the efficient delivery of water services. Overall efficiency was achieved by one large company in 2021 and one small company in 2019 and 2020. The outcome of our empirical analysis demonstrates the excellent skills of managers in technically efficient companies, regardless of company size and region. That outcome may be of interest to regulatory institutions and the management of individual water companies.
