Areas of Focus

Our core focus is always on innovation in local processes. We have topical expertise in community and household water systems and treatment processes, decentralized sanitation systems, and approaches to hygiene practices. In addition, we leverage tools such as ICT platforms, sensors and IoT technologies, artificial intelligence, machine learning, and data analytics.


Community and Household Water Systems and Treatment Processes


Decentralized Sanitation Systems

Technology Development

Ensuring available technologies and localized decision support tools for decentralized water systems (rainwater, wells)

Building low-cost, simple to use advanced technology platforms for rural water systems to improve management

Optimizing use of available urban sanitation assets to sustainably improve services

Understanding the drivers and control mechanisms to high pathogen exposure environments in urban settings

ICT platform development (user engagement/design, etc.)

AI/machine learning (computer vision, prediction, etc.)

Data analytics (SEM, RCTs, longitudinal observations, data source integration)


Working with underserved communities to solve critical challenges around water security and safety, sustainable sanitation solutions, and democratizing access to digital technologies and data analytics.


About GHE

We are a hybrid organization that systematically leverages the best aspects of research, non-profit work, consulting, and product development to provide a unique ecosystem that maximizes innovation and scalability for products and ideas that enable local problem solving in water and sanitation challenges. 

Our team brings experience from business incubators and startups, the CDC and other USG institutions, the UN, academia, and other large international foundations with experience and networks across 6 continents and 20+ countries.


Solutions-oriented organization solving problems at the nexus of water, sanitation, and technology with underserved communities


Water: US Virgin Islands Point-of-Entry Treatment


Water: US Virgin Islands Territory-wide Program and Policy


Water: Community Water System Mapping (CWSMap) Platform

90% of households use contaminated rainwater for domestic activities. Led by community leaders, we are supporting the adaptation and evaluation of various locally available water treatment technologies for cost-effectiveness given local water use habits.

To empower local stakeholders with evidence-based practices and technologies for regional water programs and policies, we are conducting a scalability analysis for components of a pilot water treatment program and developing a treatment decision support tool for households (digital and analog).

Traditional water system mapping tools are too complex and too expensive for rural, low-resource communities to access. Therefore, we are developing an easy-to-use digital platform, CWSMap, to allow volunteer water operators to make informed decisions about operation and maintenance of their systems.

Sanitation: Livestock Facility Effluent Control

Globalization concept

Tech: Global Health Information Intervention Framework


Tech: Computer Vision-Google Street View Environmental Health Tool

In collaboration with the Indonesian Government and UN, we are providing capacity development and guidance on monitoring approaches and control technologies for effluent and rivers associated with livestock facilities. The primary focus is on pathogens and antimicrobial resistance.

As software and information become an increasingly more central part of engineering and public health solutions, we have developed a typology and framework for classifying and optimizing information interventions.

Individual health is often driven by environmental health characteristics of communities. Here, we are exploring the use of Google Street View imagery, computer vision models, and bioinformatic methods to evaluate associations between environmental health characteristics and child health outcomes.
