Lotus Water Chlorine Dosing Device
Stanford University with International Centre for Diarrhoeal Disease Research
A chlorine dispenser to attach to flowing water systems.
The Lotus Water Project aims to reduce the transmission of water-borne diseases through the implementation of community-level water disinfection throughout urban slums. This chlorination device (currently a prototype) utilizes basic principles of fluid mechanics to dose water exiting a hand pump with the necessary amount of chlorine, making it safe to drink and store for later use. The chlorinator relies on pressure differences created by the device’s geometry to inject a dose of chlorine proportional to the amount of water flowing through the hand pump without using electricity (i.e. venturi effect).

Lotus water was specifically designed for use in slums of Bangladesh. Interview with representative.
As a prototype, Stanford Researchers and the International Centre for Diarrhoeal Disease Research, Bangladesh are deploying the product. Lotus Water is developing a strategy for scaling its approach to water disinfection, one option being establishing an independent organization with full-time employees and a distribution network.

This water system is expected to be leased to landlords, therefore prices are covered by small increases in renter’s payments, estimated in the amount of $0.25 USD per month, per household. Interview with representative
