From Technologies to Lasting Services

A wide range of conventional and innovative water, sanitation and hygiene (WASH) technologies are readily available to implementing sector agencies and communities worldwide. Affordable solutions for achieving sustainable WASH services are within reach, yet few have been mainstreamed and/or scaled up successfully. Despite the failure of various conventional WASH technologies to deliver a sustainable service, the sector has been hesitant about adopting innovative technologies.

It can be challenging to assess if a water, sanitation and hygiene (WASH) technology really has the potential to provide sustainable services and continue to work at scale. In response to this, WASHTech project has developed and tested a methodological framework that envisages helping the sector identify technologies that work and may be brought to scale. In collaboration with sector stakeholders in Burkina Faso, Ghana and Uganda, WASHTech has developed the following tools that help with this assessment:

The Technology Applicability Framework (TAF) is a decision-support tool that helps, using a participatory process to assess if a specific technology is applicable in a certain context and can be scaled up. TAF functions in two ways within a given context: a) it identifies a sustainable and applicable WASH technology from those that are not; and b) it reveals risks and supportive factors that influence the successful introduction or roll out of a technology. A complementary tool, the Technology Introduction Process (TIP) defines the roles and activities of key actors needed for successful introduction and scaling up of technologies in a country.

In all three countries, national level ‘host’ institutions with a formal role in technology introduction in the country have agreed to take TAF and TIP forward.

In this webinar, participants will:

  • Learn more about bottlenecks to lasting service delivery and how the Technology Applicability Framework (TAF) and Technology Introduction Process (TIP) can help
  • Understand key elements of TAF and TIP
  • Discover how TAF and TIP have been applied in Ghana
  • Reflect on potential use of the tools in their own work
