Cambodia: sale of ceramic filters supported by awareness raising activities and social marketing

Combine filter promotion with access to Microcredit

Our partner Hydrologic is a Cambodian social enterprise whose objective is to supply drinking water by selling localy supplied ceramic filters to the rural and suburban populations in 19 of the country’s 23 provinces. Through the company, two distribution models have been successfully tested: the retail of the product to resellers, and direct sales in remote villages. Hydrologic is innovative with its direct sales: Clean Water Experts (CWE) raise awareness about the hygienic and economic benefits of consuming drinkable water in the whole community. Accompanied by members of a microfinance NGO, they offer buyers the chance to take out a loan of US$20 to US$40 per filter. Estimates show that 30% of village households become interested and involved in the direct sales process and that 60% of these people buy a ceramic filter.

Inspire thanks to innovative design to ensure sales

Yet, the company’s biggest innovation was to create a ceramic filter they call the Super Tunsai, which is more aesthetic and more practical than the regular model. In parallel, they have created bespoke training activities (e.g. learning forums on health, training on sanitation), as well as merchandising products (T-shirts, caps, branded treated-water bottles, information booths, flyers and posters).
