Impact through Innovation Cambridge




In rural world communities, harvested rainwater is seldom disinfected safely. 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.

BlueTap is a low-cost chlorinator designed for use in the water systems of rural communities, which allows for consistent flow-dependent injection of chlorine into a raw water conduit leading from a water source to a storage tank. 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 developing methods to 3D print elements of the product, to facilitate distribution 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 to install and maintain the product while providing support from the UK.
