Our team has designed a novel liquid chlorine doser (the Venturi) that employs properties of fluid dynamics to automatically add liquid chlorine at the point of water collection (e.g. taps), without moving parts or electricity. The Venturi’s ability to precisely dose at tap outflows across varying flow rates enables consistent dosing under the taste detection limit of most users, increasing user acceptability. The use of dilute bleach as the chlorine source enables a large potential target market because dilute bleach is widely available in low-income settings.
The Venturi uses commercially available Waterguard as its liquid chlorine source; bottles can be poured directly into the device when refills are needed. Currently the Venturi is installed at Kiosks and health care facilities in Western Kenya. We are working on making the Venturi commercially available in Kenya.
In Kisumu, Kenya, we conducted a competitive market analysis and developed a business plan for POC in collaboration with PATH and SWAP. We completed a business pilot in which we sold lease and lease-to-own sales packages to kiosk owners. Kiosks paid >$250 USD over 6 months to own the devices and they have selling chlorinated water now for two years. Currently we are partnered with CARE and KEMRI to evaluate and develop a scaling model for health care facilities.
