Lack of sanitation facilities is a common occurrence in informal settlements that are common in most developing countries. One challenge with sanitation provision in these settlements is the cost and financing of sanitation.

This study aimed at estimating the cost of sanitation, and investigating the social and economic dynamics within Kisumu’s informal settlements that hinder provision and uptake of sanitation facilities. Primary data was collected from residents of the settlements, and using logistic and hedonic regression analysis, we identify characteristics of residents with sanitation facilities, and estimate the cost of sanitation as revealed in rental prices.

Our study finds that sanitation constitutes approximately 54% of the rent paid in the settlements; and dynamics such as landlords and tenants preferences, and sharing of sanitation facilities influence provision and payment for sanitation. This study contributes to general development by estimating the cost of sanitation, and further identifies barriers and opportunities for improvement including the interplay between landlords and tenants.

Provision of sanitation in informal settlements is intertwined in social and economic dynamics, and development approaches should target both landlords and tenants, while also engaging various stakeholders to work together to identify affordable and appropriate sanitation technologies

Comparing Sanitation Delivery Modalities in Urban Informal Settlement Schools: A Randomized Trial in Nairobi, Kenya

The provision of safely managed sanitation in informal settlements is a challenge, especially in schools that require durable, clean, sex-segregated facilities for a large number of children. In informal settlements in Nairobi, school sanitation facilities demand considerable capital costs, yet are prone to breakage and often unhygienic.

The private sector may be able to provide quality facilities and services to schools at lower costs as an alternative to the sanitation that is traditionally provided by the government. We conducted a randomized trial comparing private sector service delivery (PSSD) of urine-diverting dry latrines with routine waste collection and maintenance and government standard delivery (GSD) of cistern-flush toilets or ventilated improved pit latrines.

The primary outcomes were facility maintenance, use, exposure to fecal contamination, and cost. Schools were followed for one school year. There were few differences in maintenance and pathogen exposure between PSSD and GSD toilets. Use of the PSSD toilets was 128% higher than GSD toilets, as measured with electronic motion detectors.

The initial cost of private sector service delivery was USD 2053 (KES 210,000) per school, which was lower than the average cost of rehabilitating the government standard flush-type toilets (USD 9306 (KES 922,638)) and constructing new facilities (USD 114,889 (KES 1,169,668)). The private sector delivery of dry sanitation provided a feasible alternative to the delivery of sewage sanitation in Nairobi informal settlements and might elsewhere in sub-Saharan Africa.



The Sanitation-Education Connection: What’s a toilet worth in Kenya?

Published on Nov 19, 2016

Sanitation is a critical, yet often overlooked fundamental human right. This documentary, first in a series, broadly describes the worth of the sanitation-education connection in one area of Kenya, by defining its challenges and presenting solutions.

Water may be life, but the quality of our lives is determined in part by our health and wellbeing. It may be surprising to many of us, but in countries like Kenya, health is largely affected by access to toilets. Sanitation is a critical, yet often overlooked fundamental human right. Globally 2.5 billion people lack access to adequate sanitation. The resulting health risks touch all ages and affect every aspect of life: education included. Impacts reverberate through economies and generations as individuals fail to meet their full potential. Unfortunately sanitation is generally not a topic of common conversation nor is it often an economic priority. It becomes then, a silent emergency.

USAID APHIAplus -Community-led sanitation in Nakuru County, Kenya

Published on Aug 3, 2016

APHIAplus Nuru ya Bonde project works with technical teams in five Kenyan counties to improve water, sanitation and hygiene (WASH). Over the past five years, the project has helped to significantly increase access to functional latrines in the five counties it covers.

In Nakuru County, Efforts are focused on working with public health officials and communities to stamp out open defecation, practiced by only 3% of the community. This video presents some of the project’s work in the county.


High-Resolution Spatial Distribution and Estimation of Access to Improved Sanitation in Kenya

High-Resolution Spatial Distribution and Estimation of Access to Improved Sanitation in Kenya. PLoS One, July 2016. Authors: Peng Jia , John D. Anderson, Michael Leitner, Richard Rheingans

Background – Access to sanitation facilities is imperative in reducing the risk of multiple adverse health outcomes. A distinct disparity in sanitation exists among different wealth levels in many low-income countries, which may hinder the progress across each of the Millennium Development Goals.

Methods – The surveyed households in 397 clusters from 2008–2009 Kenya Demographic and Health Surveys were divided into five wealth quintiles based on their national asset scores. A series of spatial analysis methods including excess risk, local spatial autocorrelation, and spatial interpolation were applied to observe disparities in coverage of improved sanitation among different wealth categories. The total number of the population with improved sanitation was estimated by interpolating, time-adjusting, and multiplying the surveyed coverage rates by high-resolution population grids. A comparison was then made with the annual estimates from United Nations Population Division and World Health Organization /United Nations Children’s Fund Joint Monitoring Program for Water Supply and Sanitation.

Results – The Empirical Bayesian Kriging interpolation produced minimal root mean squared error for all clusters and five quintiles while predicting the raw and spatial coverage rates of improved sanitation. The coverage in southern regions was generally higher than in the north and east, and the coverage in the south decreased from Nairobi in all directions, while Nyanza and North Eastern Province had relatively poor coverage. The general clustering trend of high and low sanitation improvement among surveyed clusters was confirmed after spatial smoothing.

Conclusions – There exists an apparent disparity in sanitation among different wealth categories across Kenya and spatially smoothed coverage rates resulted in a closer estimation of the available statistics than raw coverage rates. Future intervention activities need to be tailored for both different wealth categories and nationally where there are areas of greater needs when resources are limited.


Handwashing With a Water-Efficient Tap and Low-Cost Foaming Soap: The Povu Poa “Cool Foam” System in Kenya

Handwashing With a Water-Efficient Tap and Low-Cost Foaming Soap: The Povu Poa “Cool Foam” System in Kenya. Global Health: Science and Practice, June 2016.

Authors: Jaynie Whinnery, Gauthami Penakalapati, Rachel Steinacher, Noel Wilson, Clair Null, Amy J Pickering.

The new handwashing system, designed with end user input, features an economical foaming soap dispenser and a hygienic, water-efficient tap for use in household and institutional settings that lack reliable access to piped water.

Cost of the soap and water needed for use is less than US$0.10 per 100 handwash uses, compared with US$0.20–$0.44 for conventional handwashing stations used in Kenya.


  • Soap security: The soap foamer is attached to the system, preventing theft
  • Affordability: Just 5 g of powdered or liquid soap mixed with 250 mL of water can provide 100 uses for US$0.10 (cost includes soap and water).
  • Hygienic: The innovative swing-tap design is bidirectional and can be used with the back of the hand or wrist, limiting recontamination of hands after handwashing.
  • Water-frugality: The water flow is sufficient for handwashing while providing a 30-77% reduction in water usage compared with conventional methods.
  • Scalability: Components are specifically designed for low-cost mass production and deployment, estimated at US$12 per unit.
  • Adaptable: The 2 handwashing station configurations can be adapted to meet different needs and preferences and can be used in households and institutional settings, such as schools and health centers.
