Managing Water for the City of the Future

» Wastewater Resources section

Focus 1: Situational analysis in Lima, Beijing, Accra and Hamburg. Urban agriculture contributes to a wide variety of urban issues; it provides multiple benefits for urban inhabitants and can have many different functions. An assessment was conducted to determine which institutions should be involved in the working group on urban agriculture, what need there is for a particular demonstration, and what research should be undertaken.

• Situational analysis of urban water for urban agriculture

Focus 2: Adoption and operational performance reports on practical experiences in applying "ecosan" source-separating sanitation systems. A comprehensive overview of drivers and barriers for ecosan implementation, operational experience and user perception based on over 100 case studies is provided. Performance improvements to the tannery industry are also explored with a focus on Colombia.

• Cross country assessment of adoption and performance of ecosan systems
• Industrial performance improvements

Focus 3: Treatment processes for pharmaceuticals presents research on biological and physico-chemical removal of these compounds from concentrated wastewater flows including the potential uptake by plants.

• Ecosan
  • Inventory of the most important pharmaceutical compounds
  • Biodegradability and fate of phamarceutical compounds
  • Development of a bio-physical-chemical system for removal of micro-pollutants
  • Plant growth tests, addressing fate and behaviour of pharmaceutical residues
• Public urinal pharmaceutical analysis – Accra
• Natural systems for wastewater including BF and ARR

Focus 4: Agricultural use of nutrients explores strategies, guidelines, market value and logistics associated with use of sewage based nutrients. Demonstrations in Chongqing, Lima, Accra and Beijing provide experience and data and link action research to demonstrations (see demos for further info). Water recycling aspects are covered under Water Supply research area.

• Guidelines and standards for ecological sanitation
• Inventory of agriculture demand and value of application of ecosan fertilizers
• Current and future transport systems for ecosan products to agriculture
• Urine reuse report

Focus 5: Best practice and decision support systems builds on the knowledge derived under Focus areas 1-4 and outlines approaches for sanitation technology selection under various conditions.

• Evaluation of ecosan alternatives for urban areas – focus on Accra
• Best practice and decision support for ecosan
• Sustainable industrial emission limits

Focus 6: Institutional change explored the arrangements between government and stakeholders with a focus on resolution of conflicts and regulatory change.

• Conflict resolution
• Policy guidelines for promoting water treatment systems which reuse domestic and municipal waste water for irrigating urban and peri-urban green areas
