E-book on sustainable sanitation systems

Globally, 80% of wastewater flows back into the ecosystem without being treated or reused. There is therefore an urgent need for a paradigm shift towards affordable technological alternatives for wastewater treatment, which should be tailored to local and specific contexts.
An option for low income countries and rural areas, is to promote wastewater treatment in ponds and lagoons, as well as the utilisation of the treated effluents for crop irrigation and aquaculture. The valuation of faecal sludge-derived products can offset treatment cost and act as an incentive to create sustainable wastewater treatment and services.

WaterLex and UN Environment recently launched the E-book Sustainable Sanitation Systems: Health, Environment and Governance Challenges: The Case of Human Rights-Based Policy Reform in Alternative Wastewater Management Strategies, which addresses these issues.
