The reuse or utilization of wastewater, faecal sludge and its embodied resources is widely acknowledged in the field of sanitation as a key component of complete sanitation. Reuse, for agriculture and other applications, is conventionally considered a means of mitigating water shortage or abating water pollution. We contend that reuse- oriented sanitation can also be leveraged to improve the long-term efficacy of a treatment scheme by providing tangible and quantifiable incentives for sound operation and maintenance that exceed those associated with running a disposal facility. The standards that need to be met for agricultural reuse are different from those required for discharge to the aquatic environment. This difference requires a change in the design philosophy and can lead to cost savings in the type of treatment process, the energy demand and the skills needed for operation. So, rather than a more complex system, wastewater treatment designed for agricultural reuse can result in a more appropriate plant for developing countries striving to enhance access to improved sanitation. To facilitate a culture of designing site-specific and reuse-oriented systems from the outset of the planning process, this chapter introduces a five-step planning tool, Design for Service (DFS). DFS defines wastewater as a resource and choices about its reuse inform the infrastructure design including site and technology selection, and plant scale. We highlight reuse schemes at various stages of implementation in South Africa to exemplify difficulties faced in the absence of accessible planning frameworks. To demonstrate how DFS can be used for rehabilitating schemes that have fallen into disrepair and for the design of new reuse-oriented sanitation systems, we describe projects that are currently underway in Ghana and China, respectively.

Attempts to implement participatory processes are often complicated by realities which make objectives of participation unattainable. Hence, if participation is to mean more than good intentions, it is vital to understand the strategies deployed by international nongovernmental organisations (INGOs) in participatory development. This study employed a qualitative case-study approach to evaluate the participatory processes employed in two WASH projects implemented by WaterAid Nigeria attempting work with Local Government Areas: the Sustainable Total Sanitation project and the HSBC Water programme. WaterAid Nigeria's participatory development approach recognises the responsibility of the various tiers of government for its citizens' wellbeing, especially the need for partnership with the Local Government Area (LGA) towards the delivery of WASH services. The state, as the ‘duty bearer’, is responsible for the provision of WASH services. Thus, both projects centred on government capacity building and community empowerment through the establishment and capacity development of WASH units in LGAs, insistence on counterpart funding and the establishment of water, sanitation and hygiene committees (WASHCOMs). Despite these attempts, findings highlighted the persistence of inefficiencies within the LGA WASH system that rendered partnerships ineffective. At the community level, WASHCOMs were not sustainable. Despite the challenges of implementing partnerships between INGOs and LGAs, such partnership remains a way to improve the provision of WASH services in Nigeria and other low- and middle-income countries. To better work within the participatory model, WASH INGOs should explore how to better use existing LGA arrangements for service delivery. Additionally, the LGA, as a duty bearer, could foster genuine, non-discriminatory spaces for the participation of communities by taking political, socio-economic and cultural differences into account.
