Sanitation Services

The safe management of fecal waste is a major public health and economic challenge in most cities of the developing world. Working across continents, Aquaya aims to support local institutions to develop appropriate sanitation solutions.

Fecal Sludge Management Services in Port Harcourt, Nigeria

Santiation services in Port Harcourt, Nigeria are limited. Most residents in formal city neighborhoods maintain their own septic tanks, very often emptying the contents in illegal dump sites. Residents of informal settlements use hanging piers or ‘flying toilets’. Waste is not being safely managed across most of Port Harcourt. We aim to understand existing fecal

Sanitation value chain study in rural areas and small towns in Haiti

Aquaya is designing and carrying out a value chain analysis on sanitation products and services available in small towns and rural areas in Haiti. The study will be conducted at national level; however a special focus will be placed on the Centre, Sud, Grande Anse and Nippes departments where more intensive supply-chain strengthening activities will

Pro-Poor Sanitation Surcharges in Kenyan Cities

The safe management of fecal waste is a major public health and economic challenge in most cities of the developing world. Coping with poor sewerage infrastructure and rapid population growth will require significant investments in both standard waste water treatment systems and on-site fecal sludge containment and removal. The objective of this research assignment is

Water Quality Monitoring

Accurate information is important for evaluating service delivery, improving efficiencies, and targeting resources.  Water sector data, however, are limited in much of the developing world. The objectives of our research are to develop and apply appropriate technologies and best practices that support the integration of data into water management programs.

Water Safety Plan Consultation with WHO in Asia Pacific Region

Aquaya teamed up with the World Health Organization to assess to what extent the implementation of Water Safety Plans affected water supply performance in the Asia Pacific Region. The study also assessed performance indicators of the Water Safety Plans. The study focused on addressing two main questions: -To what extent has the implementation of WSPs

Seasonal Water Quality in Port Harcourt, Nigeria

Establishing and maintaining public water services in fragile states is a significant development challenge. In anticipation of water infrastructure investments, we compared drinking water sources and quality between the dry season and the rainy season in Port Harcourt, Nigeria. In Port Harcourt, a city recovering from political and economic instability, residents have limited access to piped water,

Monitoring for Safe Water

Why doesn't microbial water quality testing meet regulatory standards in many countries?  

Sanitation Supply & Demand

Aquaya designs and administers field studies to evaluate supply chains for sanitation products and to measure consumer demand. Many efforts to improve sanitation services propose market forces for achieving distribution of emerging sanitation products, but demonstrations of commercially viable business models that reach poor consumers are limited. Aquaya is conducting research on and providing valuable data to inform decision-making on sanitation policies.


Aquaya was selected in conjunction with Tetra Tech, FHI 360, and FSG (India), to lead a USAID market-based sanitation analysis over the coming 5 years. The goal of the program is to strengthen USAID’s WASH programming at a country level and enhance global learning and adoption of the evidence-based programmatic foundations needed to achieve of the

Evaluating Marketing Strategies for Rural Sanitation Products

In collaboration with the Water and Sanitation Program of the World Bank, Aquaya is developing a randomized controlled trial in rural Kenya that will compare different marketing strategies for plastic latrine slabs and assess their health benefits.

The Market for Rural Sanitation

With support from the Water and Sanitation Program of the World Bank, Aquaya is investigating supply chains for improved latrine slabs in rural Tanzania and measuring consumer willingness-to-pay for different latrine slab products among 1, 500 randomly selected households in two districts.

Local Empowerment

Small-scale businesses often provide innovative and effective solutions to fill gaps in public services. We study examples of local entrepreneurship in the water, sanitation and hygiene (WASH) sector. We also administer WASH research fellowship programs to empower African researchers with the tools to address Africa’s WASH challenges.

Our goals are to identify the factors that promote local solutions and the strategies that will expand their reach among lower income groups.

Teaching and Dissemination

As experts in the field, staff are solicited to assist in education of water and sanitation testing methods and data analysis and dissemination of related information and expertise. November 2016 – Dr. Ranjiv Khush was a guest presenter at UNICEF in Copenhagen, Denmark. UNICEF is interested in building capacity for water quality safety and is

ICT & Business Development

Aquaya advises on data management tools that support performance monitoring, survey efforts, and evaluations. Where existing open source software tools are appropriate, we optimize and configure these tools to address our clients’ needs. In addition, Aquaya builds tools in-house when we identify software gaps.

Unleashing the full potential of local, independent entrepreneurship in the WASH sector often requires business management support and access to business financing. Aquaya collaborates with development partners to ensure that these services reach promising entrepreneurs.
