It has so far only been installed in Kenya, however IPA is planning to scale up the program. The system has the potential to work on a global scale as a solution to waterborne diseases. Studies show it improves health at a cost of US$20 per [http://www.who.int/healthinfo/global_burden_disease/metrics_daly/en/index.html DALY] (Disability Adjusted Life Year). Approximately 100$ per DALY is considered very cost effective.

===Construction, operations and maintenance===
[[Image:chlorine dispenser.jpg|thumb|right|200px|Chlorine dispenser in use]]A dispenser of dilute chlorine solution is installed on a fixed stand in a lockable box. Below the box is a dosing valve so users turn a knob and a specific dose of chlorine is released. This dose is appropriate to treat the amount of water usually collected. As the water is transported back home, there is contact time for the chlorine to act.
The dispensers need to be refilled regularly. Not much maintenance is required since the dispensers are made of plastic.
===Costs===
The total costs were estimated at $0.15 per person per year. This is about a quarter of the cost of retailing chlorine.
===Field experiences===
The system has been extremely successful in Kenya. 20 dispensers were installed at water points supplying water to around 5000 people in rural areas. Previously around 8% of households used chlorine to disinfect the water. A study 6 months after installation, showed 61% of households used chlorine and this number is still increasing
