WT10 - Automatic Well-water Treatment System

The WT10 will automatically and precisely treat water as it is being pumped from a well at a cost of approximately 20 cents per cubic meter and transmit information about well usage and well-pump health to a central database.

Stage 2: Research & Development

Key component testing (proof-of-concept testing) of the WT10 was completed in 2017. Development of the first prototype is underway.

Globally, 844 million people lack access to basic drinking water services and nearly one in five individuals relies on wells or a borehole as a drinking water source. While wells and boreholes are considered an improved drinking water source, research shows anywhere between 10-41% of wells/boreholes—affecting an estimated 423 million people—are faecally contaminated.



The WT10 inexpensively, reliably, and accurately treats well water with chlorine, one of the most common and effective forms of water treatment. The chlorine is produced from common table salt, solar energy, and water. By treating the water at the collection point, and doing it automatically and precisely, problems associated with under- and over-treatment are avoided, as are bad odor and flavor - all things that discourage the consumption of chlorinated water.

Target Beneficiaries

The WT10 is intended to serve communities, schools, households and other groups that rely on water pumped from bore holes and other sources. The current design is suitable for use on well pumps that serve 170 - 340 users per day. Later versions will accommodate wells that serve larger communities.

Mission and Vision

Our goal is to provide 17 million people with access to safe water by 2030.

Innovation Description

The WT10 generates chlorine using stored salt, water from the well, and solar electricity, then automatically and precisely doses the chlorine into well water as it is dispensed from the well pump. On a daily basis, the WT10 automatically connectsto a local cellular network and transmits operational data such as system usage, system health, consumable levels, pump health, and other information to a central server.

Competitive Advantage

There are currently no devices that automatically generate chlorine and treat water as it is being pumped from manual well pumps. Other chlorine generators require that the chlorine be manually dosed into the water which can result in under- or over-dosing. Other solutions rely on liquid or dry chlorine that must be sourced, transported, and stored - this adds costs and risks. Treatment systems that rely on filtration require various levels of user interaction, do not prevent recontamination, and relies on behavior changes. Simply stated, there is no approach that offers the safety, convenience, and low-cost of automatically dosed chlorine generated from salt.

Planned Goals and Milestones

We are transitioning from proof-of-concept testing to product development. Over the course of the next 21 months, alpha- and beta- prototypes will be produced, electronics, firmware and software developed, the system will be lab and field tested, market research performed, and complete regulatory testing and certification.
