In Urban Africa, water and sanitation utility companies are facing a huge backlog of sanitation provision in the informal settlement areas. In order to clear this backlog, new investment is required. However, to select appropriate sanitation technologies, lifecycle costs need to be assessed. The aim of this research was to establish lifecycle costs for appropriate sanitation technologies in informal settlement areas. Three sanitation options were compared: simplified sewerage, urine diversion dry toilet (UDDT) and Ventilated Improved Pit (VIP) latrine. Three scenarios for simplified sewerage were considered; gravity flow into existing conventional sewers with treatment; new-build with pumping and treatment; and new-build gravity flow with treatment. The study revealed that simplified sewerage is the cheapest option for Soweto informal settlement, even when the costs of pumping and treatment are included. Gravity simplified sewerage with treatment is cheaper than the UDDT system and VIP latrine at all population densities above 158 and 172 persons/ha, respectively. The total annual cost per household of simplified sewerage and treatment was US$142 compared to US$156 and US$144 for UDDT and VIP latrine respectively. The costs of simplified sewerage could be recovered through a monthly household surcharge and cross-subsidy summing US$5.3 The study concluded that simplified sewerage system was the first choice for Soweto informal settlement areas, given the current population density.

About 55% of energy used in the South African water cycle is for wastewater treatment, with the bulk of this energy associated with aeration in biological processes. However, up to 15% of wastewater energy demand can be offset by energy generation from sludge (power and/or combined heat and power), while best practices adoption can deliver energy efficiency gains of between 5% and 25% in the water cycle. Advanced process modelling and simulation has been applied in this study as a tool to evaluate optimal process and aeration control strategies. This study further applied advanced modelling to investigate and predict the potential energy consumption and consumption cost pattern by the South African wastewater sector resulting from implementation of optimal process and aeration energy use reduction strategies in support of sustainable municipal wastewater management. Aeration energy consumption and cost savings of 9–45% were demonstrated to be achievable through implementation of energy conservation measures without compromising final effluent regulatory compliance. The study further provided significant potential future energy savings as high as 50% and 78% through implementation of simple and complex aeration energy conservation measures respectively. Generally, the model-predicted energy savings suggest that adoption of energy efficiency should be coupled with electricity generation from sludge in order to achieve maximum energy consumption and cost savings within the South African wastewater services sector.

Household water end-uses have been extracted from high-resolution smart water meter data in various earlier studies. However, research on end-use disaggregation from rudimentary data is limited. Rudimentary data is defined as data recorded in intervals longer than 1 min, or data recorded with resolutions larger than 0.1 L/pulse. Developing countries typically deal with rudimentary data, due to the high cost and high resource investment associated with high-resolution data. The aim of this study was to extract useful event characteristics from rudimentary data, without identifying the actual end-uses per se. A case study was conducted in the City of Johannesburg, South Africa, where 63 homes were equipped with iPERL smart water meters. The meters recorded flow measurements every 15 s at a 1 L/pulse resolution, rendering the recorded data rudimentary. A total of 1,107,547 event pulses were extracted over the 217-day study period. Although the method presented is limited in the sense that water use events cannot be identified, the method allows for disaggregation of event pulses in the presence of rudimentary data. Using this tool, it is possible to lift valuable information from rudimentary data that would subsequently benefit service providers in setting water demand strategies.

Rising rates of urbanisation in Africa, without attendant improvements in critical infrastructure, have occasioned gaps in the provision of basic services in cities across the continent. Different systems and scales of service delivery — decentralised and centralised, public and private — coexist and often compete in urban spaces but rarely connect in ways that ensure the needs of the poorest are met. Our paper interrogates the value of transdisciplinary research for bringing actors in these systems together to co-produce knowledge for inclusive and sustainable outcomes. Drawing on empirical data from two complementary projects in four African cities, we demonstrate the possibilities for facilitating this kind of knowledge co-production among system actors in the food, water and energy domains. We show, through a comparative approach, elements of the co-production process that enable more responsive engagement by traditionally detached policy actors. From our findings, we generate a framework that local researchers serving as ‘knowledge intermediaries’ can use to stimulate research-policy-society interactions aimed at fostering sustainable and inclusive service delivery across Africa. By synthesising the findings from local case studies into a widely applicable framework, our analysis informs both the theory and practice of transdisciplinary sustainability research in the African context where the imperative to bridge gaps in methodological innovation and service delivery is high.

Water Sensitive Design (WSD) is gaining attention as a Nature-based Solution (NbS) to urban water problems. It incorporates green infrastructure with engineered urban water systems through innovative design of the built environment and urban landscape. In Africa, Johannesburg and Cape Town are two cities engaging with WSD at a policy level. This paper uses the Strategic Niche Management (SNM) approach in a comparative analysis of ongoing engagement with WSD in Johannesburg and Cape Town. We explore the extent to which this engagement signals the launch of the transition towards water resilience. WSD represents a niche that is in synergy with the visions of sustainable urban (water and environmental) management in both cities. Results indicate a progressive engagement with WSD by different actors at regime and niche levels. However, the lack of coordination and capacity deficiencies due to limited social networks and higher order learning are challenges that constrain take-off and further consolidation of the WSD approach in the transition towards water resilient futures. Furthermore, we find urban governance practitioners struggle with reconciling the pursuit of visions of sustainability to be realised through nature-based urban development with the pressing infrastructure deficits that persist in most African cities.

Green roofs affect the urban food-water-energy nexus and have the potential to contribute to sustainability. Here we developed a generalizable methodology and framework for data-sparse cities to analyze the food-water-energy nexus of green roofs. Our framework integrates the environmental costs and benefits of green roofs with food-water-energy systems and makes it possible to trace energy-water-carbon footprints across city boundaries. Testing the framework in São José dos Campos (SJC), Brazil and Johannesburg, South Africa, we found that green roofs are essentially carbon neutral and net energy consumers from a life cycle perspective. SJC is a net water beneficiary while Johannesburg is a net water consumer. Rainwater utilization could save irrigated water, but requires 1.2 times more energy consumption. Our results show that SJC and Johannesburg could direct their green roof development from local food production and energy saving, respectively and highlight opportunities for green roof practices in cities.
