Within RWSN to date, the main technologies developed and promoted for Self-supply have tapped groundwater (i.e. hand dug wells and boreholes with various pumps). Given the increased recognition that rainwater harvesting also has considerable potential, and success stories (e.g. in Uganda and Thailand) this strategy has a particular focus on rainwater. Over the coming three years, RWSN will build up a community for rainwater harvesting and promote good practices. The emphasis is on domestic use, but includes rainwater harvesting for agriculture. Not all water sources improved incrementally will immediately provide safe water. Thus there is need to consider household water treatment options within Self-supply, key aspects of water safety planning and quality assurance for products and services. Closer collaboration with the household water treatment and safe storage network will be established.

Not all technologies are applicable for every context and even apparently “clever” technologies can fail if they are not appropriate, or are not introduced to the market properly. The Technology Applicability Framework (TAF) is a method for assessing the applicability of technologies for a given context. It was developed and tested by three RWSN partner organisations (IRC, Skat and WaterAid) together with organisations in Burkina Faso, Ghana and Uganda and has subsequently been applied in Tanzania, Nicaragua,  Sierra Leone and the Philippines. Using the TAF at the early stage of product development can help to identify bottlenecks that would hinder the uptake of a technology in a context and identify mitigation measures. For more details see www.washtechnologies.net .

Within this strategy, efforts will be undertaken to promote the TAF widely, evaluate it and work towards a formal RWSN endorsement and training.

Topic: Technologies

Expected outcomes (2015-2017):

1.Technology options for Self-supply are selected using an agreed RWSN standard by at least five organisations.

2.Rainwater harvesting techniques are incorporated into government policy and practice in three countries.

3. Improved understanding of RWSN members of household water treatment and safe storage options.

Activities & Publications (2015-2017):

1. Sharing experiences of organisations that are already using the Technology Applicability Framework (TAF) for technology assessment and development, supporting others who are interested and promoting it.

2. RWSN Publication: Using the Technology Applicability Framework

3. Building online community of practice and facilitating dialogue and sharing of experiences regarding rainwater harvesting.

4. Joint networking and sharing with the Household Water Treatment and Safe Storage network (hosted by WHO).
