Disinfection of harvested rainwater in rural world communities is often underdeveloped. With an estimated 1.8 billion people still drinking from contaminated sources, access to clean drinking water is one of today’s most pressing global issues.

In communities with access to chlorine, disinfection is often performed manually. This requires the attention and judgment of the resident and can result in problems like over-chlorination or under- chlorination.

A low cost chlorinator is designed for use in rural community-scale water systems, which allows for consistent flow-dependent injection of chlorine into a raw water conduit leading from a water source to a storage tank based upon Bernoulli’s principle. 

The total cost of the device is less than $15 US. The device has been installed and is being tested by the Office National d’Électricité et de l’Eau Potable (ONEE) in a rural community water system in Morocco.

We are looking into the feasibility of 3D printing elements of the product to distribute them in developing countries. We envision our final product being a kit that can be installed on existing water supply systems. Our role would be to supply these kits to local plumbers, train them on installation and maintenance and offer them online support from the UK.
