Willingness-to-Pay For Sanergy Products and Services in Kisumu, Kenya

Sanergy builds healthy, prosperous communities by making safe sanitation, accessible and affordable for everyone, forever – starting with the urban slums of Nairobi, Kenya.


Sanergy is currently expanding their container-based sanitation (CBS) services into Kisumu, Kenya. Container-based sanitation (CBS) is a sanitation service that provides toilets that collect human excreta in sealable, removable containers on a regular basis and safely disposes of or reuses excreta. In CBS facilities, liquid and solid human waste are separated and deposited in removable containers, which are collected on a regular basis for safe disposal or resource recovery. 

In February 2021, the Aquaya Institute conducted a survey of potential customers in the low-income area of Nyalenda in Kisumu to estimate demand and inform pricing for Sanergy’s Fresh Life and Fresh Fit Toilets. The Fresh Life Toilet is a standalone structure that can be used by multiple households and is often marketed to landlords as a facility for their tenants to use. In Kisumu, Sanergy charges a total monthly service fee of 950 KES per toilet for container collection (pricing is determined based on local market demand and varies geographically). The Fresh Fit Toilet is a small in-home facility often marketed to households with elderly or disabled members, and Sanergy charges a monthly fee of 300 KES in Kisumu. Currently, Sanergy does not charge an upfront deposit for installation or as a mechanism to cover the loss. 

In total, 302 surveys were completed among landlords, tenants, homeowners, and schools. This survey used a stated willingness-to-pay (WTP) method (double-bound dichotomous choice) in which two hypothetical questions are asked about randomly selected price points, followed by a direct question asking for the respondent’s maximum WTP. Here we present summary statistics and WTP curves, with regard to both monthly service fees and upfront deposits. Further, we also explore alternative payment models and factors that may be associated with a respondent’s WTP.
