Factors Associated With Utilization of Ecological Sanitation Technology in Burera District, Rwanda: A Mixed Methods...

The utilization of "on-site excreta decomposition technology" known as "Ecological sanitation (Ecosan)" has a rational use of human excreta. It is a resource-oriented sanitation mostly feasible in areas with rocky soil and prone to agriculture. This technology was implemented in Rwanda for more than a decade. However, little is known about Ecosan utilization in the process of scale-up in the community.

The study was carried out to determine enablers and barriers associated with the utilization of Ecosan in Burera district, Rwanda.

A mixed method study was surveyed in 374 households with Ecosan. A systematic random sampling was used to select respondents and a sample was drawn from the 3 administrative sectors of Burera district. We interviewed 20 key informants that included community leaders and sanitation actors. Bivariate, ordered logistic regression with thematic content analysis were used.

Ecosan users were unable to practice both urine diversion and the use of Ecosan by-products. Only 39.4% of households were better users. As by the survey results, primary and secondary educational status (AOR 2.60, 95% CI 1.11-6.08) and (AOR 3.49, 95% CI 1.02-11.9), frequency of fecal pit emptying (AOR 3.38, 95% CI (2.18-17.91), ash use (AOR 1.65, 95% CI (0.93-4.64) and concrete slab latrine (AOR 7.31, 95% CI (2.94-17.95) were found to be associated with better use of Ecosan. Qualitative findings suggested unaffordable cost, a touch of excreta taboos, and poor maintenance practices as key barriers to utilization.

Overall utilization of Ecosan was poor and the majority of households was not able to use Ecosan for both dry separation of urine from feces and reuse in the gardens. Upgrading existing knowledge about Ecosan with greater emphasis on the use of by-products and adopting good maintenance practices through regular training can promote better utilization of Ecosan.
