Blue Tap CIC

The Blue Tap Chlorine Doser


30% of the world still don’t have access to safe drinking water. Globally, diarrheal disease is the 2nd leading cause of death in children under 5. Many people now have access to “basic water services” but can’t drink their water as it contains pathogens. This means people become ill, boil their water, or buy bottled water. Blue Tap has designed a simple Chlorine Doser. It inserts the correct amount of chlorine into a piped water system to make it safe to drink in line with WHO guidelines. The simplicity of the design makes it easy and cost-effective to produce, install and maintain. Our rigorous training and monitoring process (enabled by IoT, conducted by local plumbers) ensures consistent, high-quality water.
