Failure is the norm for urban sanitation infrastructure in Ghana: of the rather substantial number of wastewater and faecal sludge treatment plants, with about 70 mostly decentralized systems throughout the country, less than 10 are operating effectively. This research presents an overview of the related sanitation situation in Ghana, and compares the few successful facilities with their failed counterparts in order to decipher the factors that enable the former to prevail. The research reveals important differences in the operation and maintenance (O&M) strategies, financing schemes and incentive structures in the successful versus unsuccessful facilities, which are probably not unique to Ghana. Based on the findings, we suggest a set of guiding questions for incorporation into the existing planning, funding or general decision-making framework in order to avoid commonly observed traps, which not only undermine progress in the delivery of sanitation services but also harshly affect environmental and public health.

In this article the authors document evolving attitudes, policies and roles of stakeholders in wastewater and faecal-sludge management in India, China and Ghana. In each country there is momentum for expanding not just access to sanitation at the household/community levels, but also for greater treatment and safe end-of-life management of human excreta. Governments are increasingly looking to engage the private sector, but models of engagement that make a compelling business case and instil confidence in cost recovery will have to emerge before the private sector takes an active role in wastewater and faecal sludge treatment in low-income countries.

Opportunities for public–private partnerships based on cost recovery from the reuse of human waste remain unexplored. In this paper, the authors present four potential business models involving aquaculture, biogas recovery, compost production and the use of faecal sludge as an industrial fuel, and describe their associated financial flows. The business models are based on efficiency indicators that can provide decision support to local authorities and entrepreneurs in choosing options that are best suited to local conditions and needs. The ultimate target should be that a portion of revenues from reuse can help finance less-profitable sections of the sanitation service chain.
