The project:
Drink Up Bobonaro, Timor-Leste
Technologies used:
Nazava Bening Small Water Filter, Nazava Bening 1 Water Filter, Nazava Bening 2 Water Filter, Nazava Bening XL Water Filter
Local partner:

We are working with our local partner, Hemetin Asaun Dezenvolvimento Edukasaun no Ekonomia Rural (HADEER), to distribute 480 Nazava water filters in Bobonaro district, Timor-Leste.

In June 2015 while the distribution was ongoing, Kopernik fellow Imelda Wang, visited Maliana city to assess the Drink Up Bobonaro project in Timor-Leste which began in August 2014.

By conducting household surveys, Imelda identified the impact of the use of water filters on the lives of people who bought them. The impact assessment involved interviews with 54 water filter buyers (from a total of 115 buyers when this report was composed).

The interviews were conducted over a two-week period and the impact can be summarised as follows:

  • Health – The use of water filters improved people’s health, with 62 percent of respondents indicating a reduction in health problems, such as coughing, diarrhoea, and headaches.
  • Economic – On average, up to US$18 per month can be saved by using the water filter.
  • Time saved and productivity – By using the water filter, households can save up to 90 hours per month, by not having to boil water or travel to a well. Furthermore, 76 percent of respondents stated their productivity increased significantly after using the water filter.
  • Lifestyle – Using the water filter increased the amount of water intake significantly, with 57 percent of respondents stating that they drink more water because it tastes better and it is easier to obtain.

While the positive impact was undeniable, this impact assessment raised some questions regarding who should be targeted to purchase the water filter. Customers in the city of Maliana, needed and could afford the product, but those located in last mile communities, perhaps needed the technology more, but had more trouble affording the technology due to their lower income levels. HADEER also had more trouble providing access to the products to people located outside of Maliana city due to higher transport costs.
