Description
Through piloting the rehabilitation of a wastewater treatment plant for reuse of effluent in irrigation and action research, the project will introduce a market- and end-user oriented planning approach that simultaneously closes the water and nutrient loops called "Design for Reuse" in order to effectively capture the economic value of wastewater and faecal sludge nutrients to help finance, operate and maintain treatment facilities. The external benefits of reuse such as increased yields and earnings in agriculture, environmental protection, reduced pressure on freshwater resources have been widely demonstrated but this project will demonstrate reuse as a business model through constructing and implementing value chains between treatment plants and back-end users to share the economic value of reuse with the plant operator.
Objectives
The overall objective is to improve public health and environmental integrity throughout urban and peri-urban areas of Ghana through the provision of reliable and complete sanitation. The medium term outcomes expected from the project are:
(i) the rehabilitation of one WWTP including reuse for irrigation;
(ii) knowledge products based on action research for aquaculture and biogas value chains, and
(iii) the training of local planners on design for reuse.
Rationale
The rationale for the project is the current inadequate operation and maintenance of wastewater (WW) and faecal sludge (FS) treatment plants (TPs). Less than 10% of the existing treatment plants in Ghana operate as designed based on the findings of survey carried out in 2008. The 55 existing WWTPs and 7 municipal FSTPs in the country have a total design capacity to serve about 25% of the urban population but discharge into the environment without any effective treatment is dominating.
The project will be implemented through a participatory approach, including consultation and active engagement with key stakeholders in the Ministries of Water Resources, Works and Housing (MWRWH), Local Government and Rural Development (MLGRD), local consulting engineers, and targeted back-end users, such as farmers and industry. Active support from the owners and operators of each pilot TP was a critical factor in their selection.
