Justification In Sub-Saharan Africa, excreta and wastewater disposal is characterised primarily by on-site sanitation systems. This sanitation option is more likely to increase as governments, municipalities, communities, private operators and donor agenci ...
Triggered by the Kyoto Protocol and by the aggravation of freshwater scarcity, environmental impacts should soon become key decision criteria for the planning of potable water supply projects, especially when advanced systems such as seawater desalination ...
In this paper we present six scenarios about the possible evolution of the water supply and sanitation sector in Europe, considering both liberalised and non-liberalised environments. The scenarios were developed around three macro-storylines, namely (1) p ...
This paper estimates a translog cost function for Swiss water utilities. From the cost function, we are able to estimate measures of marginal costs as well as economies of production density, customer density and scale, which are important determinants in ...
Decreasing water availability per capita in more and more countries is the result of bad management over the past centuries. The 'world water crisis', however, is not inevitable. The concept of Integrated Water Resources Management (IWRM) has been promoted ...
Traditionally, urban water services were characterised by local monopolies, where the incumbent was publicly-owned. This was explained by safety, health, economic, and technological reasons related to the sector's specificities. However, in spite of this, ...
In this paper we explore the trend of professionalization, with a focus on autonomization, in the Swiss wastewater sector. The aim is to evaluate the performance of water utilities in terms of legitimacy, efficiency and effectiveness in the context of auto ...
The purpose of this article is to identify possible scenarios for the evolution of the European water supply and sanitation sectors (WSS) in the next 15 years, on the basis of empirical knowledge of its dynamics. These are: tendered market, tendered market ...
Sediment-water fluxes are influenced by both hydrodynamics and sediment biogeochemical processes. However, fluxes at the sediment-water interface (SWI) are almost always analyzed from either a water-or sediment-side perspective. This study expands on previ ...
Private sector participation and liberalisation call for a greater and more efficient role for sector‐specific regulation. This necessitates a balanced and stable institutional regulatory framework to accommodate both public intervention and market dynamic ...
