Decentralized sanitation systems for the southern Ecuadorian Andes, assessment and challenges

Abstract:

The decentralized treatment systems for domestic effluents are an economic and sustainable alternative in comparison to conventional wastewater collection and treatment systems in rural and peri-urban areas in developing countries. However, there are still many shortcomings in the planning, implementation, operation and maintenance (O&M) of those systems. This article aims, throughout a comprehensive bibliographic review, to analyze the current state of decentralized sanitation systems in several developing countries, comparing to the technological, environmental and socioeconomic characteristics present in the rural and sub-urban communities in the southeast Andean region of Ecuador, establishing recommendations for actual systems O&M and further investments in these areas.
