Plan International USA and The Water Institute at UNC have conducted the first study to present comprehensive, accurate, disaggregated costs of a WaSH behaviour-change programme. The study calculated programme costs, and local investments for four community-led total sanitation (CLTS) interventions in Ghana and Ethiopia.

Evidence on sanitation and hygiene program costs is used for many purposes. The few studies that report costs use top-down costing methods that are inaccurate and inappropriate. Community-led total sanitation (CLTS) is a participatory behaviour-change approach that presents difficulties for cost analysis. We used implementation tracking and bottom-up, activity-based costing to assess the process, program costs, and local investments for four CLTS interventions in Ghana and Ethiopia. Data collection included implementation checklists, surveys, and financial records review. Financial costs and value-of-time spent on CLTS by different actors were assessed. Results are disaggregated by intervention, cost category, actor, geographic area, and project month. The average household size was 4.0 people in Ghana, and 5.8 people in Ethiopia. The program cost of CLTS was $30.34–$81.56 per household targeted in Ghana, and $14.15–$19.21 in Ethiopia. Most program costs were from training for three of four interventions. Local investments ranged from $7.93–$22.36 per household targeted in Ghana, and $2.35–$3.41 in Ethiopia. This is the first study to present comprehensive, disaggregated costs of a sanitation and hygiene behaviour-change intervention. The findings can be used to inform policy and finance decisions, plan program scale-up, perform cost-effectiveness and benefit studies, and compare different interventions. The costing method is applicable to other public health behaviour-change programs.

GHANA WASH PROJECT: Lessons Learned: Hybrid CLTS Approach to Improving Sanitation, 2014.
USAID’s Ghana Water, Sanitation and Hygiene (GWASH) Project aimed to improve rural sanitation access through the provision of household latrines to households in targeted communities. In the beginning of the project, GWASH used a “high-subsidy” approach for household latrine provision, providing households with a 60 percent subsidy per latrine.
It was in this vein that GWASH aimed to meet its project target of constructing 4,680 household latrines over the course of a four-year period. During the second year of the project, the Government of Ghana (GOG) implemented a new sanitation policy that promoted a pure Community-Led Total Sanitation (CLTS) approach.
The strategy is a no-subsidy approach that emphasizes community-level demand creation for sanitation improvements aimed at stopping open defecation and supporting household and community efforts to independently construct improved household latrines.
USAID Kenya Integrated Water, Sanitation, and Hygiene Project (KIWASH)
KIWASH aims to enable more than one million Kenyans across 9 counties to gain access to improved WASH services & increase access to irrigation & nutrition.
We are working with Geodesic Water Company in Kamulu, Nairobi County to increase household connections and access to water services, and improve reliability of water supply for more people.

Adopt or Adapt: Sanitation Technology Choices in Urbanizing Malawi. PLoS ONE 11(8): 2016.

This paper presents the results of a mixed-methods study examining adaptation strategies that property owners in low-income, rapidly urbanizing areas in Malawi adopt to address the limitations of pit latrines, the most common method of disposing human excreta. A particular challenge is lack of space for constructing new latrines as population density increases: traditional practice has been to cap full pits and simply move to a new site, but increasing demands on space require new approaches to extend the service life of latrines.
In this context, we collected data on sanitation technology choices from January to September 2013 through 48 in-depth interviews and a stated preference survey targeting 1,300 property owners from 27 low-income urban areas. Results showed that property owners with concern about space for replacing pit latrines were 1.8 times more likely to select pit emptying service over the construction of new pit latrines with a slab floor (p = 0.02) but there was no significant association between concern about space for replacing pit latrines and intention to adopt locally promoted, novel sanitation technology known as ecological sanitation (ecosan).
Property owners preferred to adapt existing, known technology by constructing
replacement pit latrines on old pit latrine locations, reducing the frequency of replacing pit latrines, or via emptying pit latrines when full.
This study highlights potential challenges to adoption of wholly new sanitation technologies, even when they present clear advantages to end users. To scale, alternative sanitation technologies for rapidly urbanising cities should offer clear advantages, be affordable, be easy to use when shared among multiple households, and their design should be informed by existing adaptation strategies and local knowledge.
