This publication intends to help spread awareness and knowledge about the technology of subsurface flow constructed wetlands in developing countries. Constructed wetlands (CWs) can be used as part of decentralised wastewater treatment systems, due to their “robust”, “low-tech” nature with none or few moving parts (pumps) and relatively low operational requirements. CWs can be used for the treatment of domestic and municipal wastewater or greywater, and play an important role in many ecological sanitation (ecosan) concepts.

This 12-page factsheet reflects the existing management systems practiced in various areas of Nepal in managing solid waste and contains initiatives of Municipalities; national and local NGOs/CBOs; public and private entities. The paper helps to transfer the lessons and existing practices regarding solid waste management and encourages urban, peri-urban and emerging towns for similar initiatives in urban sanitation.

All about dry urine diversion toilets, from the principles, design, construction and operation

The earthquake that struck Haiti in January 2010 and the cholera epidemic that followed from October 2010, resulted in one of the largest humanitarian relief efforts in history. Many of the internally displaced persons camps were located in urban neighbourhoods with high groundwater, making onsite sanitation extremely difficult. In response to these unique conditions a small local organization, SOIL, partnered with Oxfam Great Britain to pilot urine diversion EcoSan toilets in camps throughout Port-au-Prince. This briefing paper covers this pilot project from March 2010 through March 2012. During that 2-year period, SOIL’s toilets served over 20,000 people and treated more than 400,000 gallons of human waste, converting it to rich compost.

This is the case of a small farmer who chose to be different from the typical resource-poor farmers struggling to make a living in the degraded drylands. His deep ‘love for life’ has not only earned him a decent living, but more importantly, it has inspired many other farmers to emulate him.

The publication explains the purposes of urine diversion, its benefits and challenges, possibilities of urine treatment and reuse in agriculture. It provides an overview on design and operational aspects for equipment needed, such as waterless urinals and urine diversion toilets. An appendix with a worldwide listing of suppliers for waterless urinals and urine diversion toilet pedestals and squatting pans is also available.

After a brief introductory chapter on the Philippine sanitation situation and basic principles of sustainable sanitation, the manual focuses on the introduction of different low-cost sanitation solutions comprising the arborloo toilet, the 1-chamber and 2-chamber UDDT, hanging UDDTs, and the ecopee urinal. Each technology is briefly described by giving general information on how it works, operation and maintenance requirements, reuse or safe disposal options, and in which setting this technology might be appropriate. In addition, a picture-based guide on how to construct each technology is provided as well as the necessary technical drawings and rough cost estimates based on current prices. Since a sanitation system does not end with the toilet itself, the last chapter also provides information on the overall management of the system including collection, transport, treatment, and final reuse of urine, feces and composting products in agriculture.
