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 report gives an outline of the performance of Commercial Utilities and other divisions of the water supply and sanitation sector in meeting national targets and consumer demands.

The National Water Supply and Sanitation Council (NWASCO) regulates water providers for efficiency and sustainability of water supply and sanitation service provision. A critical function of NWASCO is the developing of sector guidelines and disseminating information to consumers. The annual sector report is one such information dissemination channel.
This article shows how local leadership through government structures, sector reforms and private investment changed the behaviour and attitudes of two communities.

In 1987, the World Commission on Environment and Development (WCED), which had been set up in 1983, published a report entitled «Our common future». The document came to be known as the «Brundtland Report» after the Commission's chairwoman, Gro Harlem Brundtland. It developed guiding principles for sustainable development as it is generally understood today. The Brundtland Report stated that critical global environmental problems were primarily the result of the enormous poverty of the South and the non-sustainable patterns of consumption and production in the North. It called for a strategy that united development and the environment – described by the now-common term «sustainable development». Sustainable development is defined as follows:«Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.»In 1989, the report was debated in the UN General Assembly, which decided to organize a UN Conference on Environment and Development.

This presentation talks about separated wastewater as a new source for fertiliser production and includes 5 conventional options for concentration/solidification: 1. Membrane filtration; 2. Precipitation with iron and aluminium; 3. Precipitation and treatment with lime; 4. Struvite production; 5. Ammonia stripping in closed loop.
