The Cambodia Sanitation Marketing Scale-Up 2.0. (SMSU) programme aimed to achieve market based sanitation solutions in rural Cambodia and support the dissemination and replication of the sanitation marketing approach to other countries.

This report summarises findings from iDE’s monitoring and evaluation efforts throughout the programme that was implemented in Cambodia from November 2014 to June 2018. It describes progress made against inception of SMSU 2.0 (the endline of SMSU 1.0) as well as progress against all SMSU project time (since Feb. 2012).

Intervention description

The report outlines the methods used to collect and analyse data and provides the key findings related to each of the project targets. It is organised around the themes of coverage and use, sales and business development.

Evidence methodology

The report uses: monthly collection of sales data from project-connected enterprises (measures direct sales); ongoing verification of latrine-business sales (including a household questionnaire to identify the percentage of poor customers, consistent use by adults and installation rate); a biennial latrine count to estimate changes in coverage at district level and calculate sales through other non-project-connected enterprises in project areas; a quarterly business profile update, collecting key business data from each active latrine business, including a one-time gender analysis studying the impact of female involvement in latrine businesses; a one-time call centre analysis to follow-up on canceled orders; and ongoing data survey for all sales pitches that do not result in an order to help determine barriers to purchase.
