Perspectives are different frameworks from which to explore the knowledge around sustainable sanitation and water management. Perspectives are like filters: they compile and structure the information that relate to a given focus theme, region or context. This allows you to quickly navigate to the content of your particular interest while promoting the holistic understanding of sustainable sanitation and water management.
This study evaluates the performance of the filter under various set-ups, to investigate long-term removal efficiencies to improve the filter design and to implement the filter in arsenic affected villages.

This study presents the experience of applying the condominial approach to expand water and sewerage networks in three contrasting Brazilian cities. It is based on the findings of a Study Tour to Brazil organised in December 2003 for utility managers and public officials from the Peruvian water sector, who were in the process of applying large-scale condominial systems in Lima for the first time. The goal of the visit was to permit the Peruvian delegation to see mature and functioning condominial systems on the ground, and to interact with local policymakers, utility managers, residents and specialists, to obtain a better idea of the challenges and potential advantages and disadvantages of implementing this system.

In this paper, it is shown that a biomaterial produced from dried water hyacinths roots, a plant that is found in abundant supply in many parts of the world, can provide a simple, effective and yet cheap method for removing arsenic from contaminated water.

The main objective of this research was to assess the feasibility of applying low cost anaerobic technology for the treatment of relatively high strength sewage of Jordan usin two-stage and one-stage UASB (Upflow Anaerobic Sludge Blanket) reactors operated at ambient temperatures.

A questionnaire survey was circulated via internet-based sanitation forums to assess the prevailing expert opinion on the appropriateness of low-cost sewerage for African cities. The questionnaire explored opinions about low-cost, solids-free sewerage (settled sewerage), low-cost, solids-transporting sewerage (simplified ed sewerage, condominial sewerage), and conventional solids-transporting sewerage.

This study focuses on the comparison of ecosan with conventional sanitation systems suitable for urban settlements in Sub-Saharan Africa. The aim of the study was to compare ecosan with conventional sanitation systems in terms of financial and economic costs and benefits, in order to assist decision-makers and sponsors of development programs to make informed decisions about relative merits of different types of sanitation. Based on two case study analysis, none of the currently implemented systems are seen to provide an obvious model for scaling up without considerable external support.
