Achieving sustainability: linking CLTS with other approaches - an example of a thorough WASH intervention in South Eastern Chad

Building resilience in a context regularly affected by crises requires innovative approaches both in terms of activities and programme management. In Sila region in Chad, a full WASH intervention has been implemented based on an iterative process of analysing the successes and failures of the programme while activities are still on-going. Barrier analysis has proven to be a strong complement to CLTS and PHAST interventions. Mixing the three approaches has resulted in significant gains in sanitation coverage and has prompted a mid-project adjustment of activities in order to target specific areas of continuing concern: access to safe water at the point of use and hand washing with soap. By performing regular analyses, the team was able to achieve better results in terms of identifying what is working well and adapting what is not, which has led to communities adopting new hygiene practices and increasing the use of WASH facilities.
