An Efficient Pollution Control Instrument: The Case of Urban Wastewater Pollution

Abstract

International audienceUrban wastewater and agriculture activities are the main sources of urban water pollution and of eutrophying nutrients in many water ecosystems. Several EU directives have been adopted and affect the control of urban water pollution. The EU legislationrequires the achievement of good ecological and chemical status in all water. This paper focuses on the use of economic instruments as a priority in the context of implementation. Our analysis only considers public wastewater utilities facing demand and capacity shocks. The proposed mechanism constitutes efficient means of moving towards sustainability by promoting full-cost pricing and considering external costs from wastewater services. Environmental damage associated with urban water pollution are internalized. The model also explicitly considers the investment needed to setup wastewater system facilities. Our results indicate that savings in capacity could be achieved by adopting the proposed incentive-based mechanism that characterizes the optimal capacity selection rule

Identifying Factors Affecting the Sustainability of Water Environment Treatment Public‐Private Partnership Projects

“…Similarly, sewage pollution threatens human health and wildlife in different regions around the world. is increase in environmental pollution underscores the need for effective environmental resource management [31].…”

“…A number of researchers have investigated water sustainability. Elnaboulsi [31] believed that sustainable development of public wastewater utilities can be achieved by promoting full-cost pricing and considering external costs from wastewater services. Reduction in drinking water consumption, also through the reuse and recycling of unconventional sources of water, has been identified as one of the goals of sustainable development.…”

Critical Factors to Achieve Sustainability of Public-Private Partnership Projects in the Water Sector: A Stakeholder-Oriented Network Perspective

“…Academics have paid more attention to water sustainability evaluation than to other topics. Elnaboulsi [35] argued that water reuse and recycling should be one of the sustainable development goals of water infrastructure projects. Pellicer-Martínez and Martínez-Paz [36] recommended using water footprints to assess environmental sustainability in water management.…”
