Project Plan 1600 households in 1-, 2- and 4-story buildings to be completed by 2007 dry urine-diverting toilets urine collection and recycling dry fecal collection, sanitisation and recycling greywater collector, treatment and reuse kitchen organics collection, composting and recycling source-separation of solid waste and recycling The Hei Zao Kui Ecosan Project The houses in the new ecosan town are being equipped with modern, affordable porcelain urine-diverting dry toilets using standards developed and applied in Sweden. Toilets and related equipment and fixtures are being developed and manufactured in China specifically for this project. Urine (ca 500 L per person per yr) will be collected on site in decentralised tanks and used in local agriculture. Water supply will be restricted to kitchen and bath use only (ca 80 L per person per day). The greywater (30,000 L per person per year) will be collected and treated on site in decentralised small treatment oxygenation and filtration facilities to reduce pathogens, BOD, N and P prior to surface soil discharge (there is no surface water in this area and the safety zone to the groundwater is 20-30 meters). Grease traps requiring maintenance will be supplied in order to improve hydraulic flow of the greywater but also to reinforce at the household level the immediate effects of waste discharge to water. Organic and solid wastes will be sorted and collected in ecosations. Fecal material (50 L per person per year) will be retained in dry form in cellar containers, which are to be emptied once or twice a year and composted along with household organic wastes and used in soil improvement. Storm and runoff water will not be mixed with any household products and will drain following the natural contours of the landscape. The tenants purchasing houses and apartments in this town will receive training and follow-up information in order to build up their level of awareness and interest in this project. Many studies will be carried out it in connection with this project both during and after construction. Performance and cost profiles will be evaluated in order to be able to make comparisons with conventional practices. The project staff has been organised into a series of R & D teams specialising in various project components e.g. infrastructure planning and installation (roads, water supply, power, IT, heating), housing architecture and building, ecotoilet installations, urine and greywater systems, agro-reuse, communications, etc. The project will undergo a period of development and testing prior to full-scale implementation in 2005 and 2006. Once in operation the model town will be the object of further performance studies by water and sanitation specialists, urban planners, urban agriculturalists, etc.
