Exploring scaling up strategies in WASH


Still billions of people lack access to water and sanitation. The urgency for access to WASH is clearly reflected in the Sustainable Development Goals (SDGs), but it is unlikely that SDG-6 will be met based on the current development-aid approach. Radical new approaches are required to get to scale in WASH. @Scale was initiated by WASTE and Aqua for All to explore such approaches and to develop tools for scaling in WASH.


How to go to scale?

What are promising models? How to arrange financing? In specific, how to use limited public funds to interest the (large) pool of private investors for water? What are bottlenecks hampering scaling and what are factors boosting scaling in WASH? What is needed to make things work in practice, on the ground? Promising new approaches with the potential for scaling are surfacing:
• Households paying for services (thus reducing or – ideally – even removing dependency on subsidies)
• Mobilisation of private sector financing, including local financing
• Re-thinking the usage of donor funds
• Involving the private sector in service delivery

@Scale wants to better understand these mechanisms for scaling, support the development of these mechanisms and support projects and organisations to put these mechanisms into practice.


We will not rest until we have answered these three questions:
• What models can provide water (at scale) for households that are not linked to the grid?
• What models can provide access to sanitation (at scale) for households that are not linked to sewerage systems?
• What models can manage faecal sludge (at scale) and allow for re-use of faecal matter?


Impact we realised

  A better, practical understanding of scaling up strategies and innovations in WASH



@Scale is built on the principle that delivery of public goods like water and sanitation cannot be solved with business models alone but require embedding in a local context. Therefore we use the diamond model to stimulate cooperation of local stakeholders: community leaders, municipalities, businesses and the financial sector.
