Technology Applicability Framework -TAF
Paul Kimera, J. Smet, A. Olschewski, A.Parker36th WEDC International Conference
‘
Introduction
Water & sanitation services fail due to choice of technology e.g. 46% of rural water supply schemes in Tanzania are not functioning
Promising technologies frequently do not go beyond the pilot stage.
WASHTech Project has 2 main outputs; TAF, Technology Introduction Process (TIP) guide
Introduction
TAF- A decision making tool on the applicability and sustainable use of a specific WASH technology and on its readiness for introduction within a specific context
Use To stimulate discussion about a WASH technology To assess the potential of a particular WASH technology in a
specific geographic and socio-economic context Assess readiness of a sector to scale up a technology Support M& E systems for technology introduction
Design Participatory tool that brings together user, regulator, and
producer/provider perspective Field data is collected by a diverse stakeholder group and verified in
workshops Designed to assess a single WASH technology
The TAF
Steps in the TAF Assessment
Screening & In-depth Assessment
The Process
Collection of relevant information for
specific technology.
Orientation workshop/ Training of field
staff
Field survey using guiding questions-
User, producer, regulator perspectives
Preliminary analysis and validation &
scoring in a workshop
National level scoring workshop

TAF is well received in Burkina Faso, Ghana & Uganda Global WASH professionals contacted confirm value of
processes & tools for evaluating & monitoring Embedding process resulted in agreed TAF hosts; Burkina Faso-
Direction des Etudes et de l'Information sur l'Eau (DEIE), Ghana - Community Water and Sanitation Agency (CWSA) and Environmental Health and Sanitation Directorate (EHSD), Uganda- the Appropriate Technology Centre (ATC) under the Ministry of Water & Environment
Tools have the potential to be used for urban water & sanitation technologies
Training Institutes to consider processes & TAF in their syllabi TAF recommended for adaptation in other countries for
sustainable WASH services
