TuriTap: Passive Water Chlorinator

SYSTEM OVERVIEW

A novel liquid chlorine doser 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 TuriTap'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. Currently installed at kiosks and healthcare facilities in Western Kenya, with efforts underway to make TuriTap commercially available.

MY CONTRIBUTIONS

• 01

  Redesigned second-generation TuriTap exterior and interfaces in Fusion 360 to improve usability, flow behavior, and field robustness

• 02

  Rapidly prototyped functional hardware using SLA (Form 3, BioMed resin), applying GD&T to ensure repeatability and assembly alignment

• 03

  Iterated designs alongside full-time engineers based on field feedback from deployments in Kenya

• 04

  Built and ran controlled-flow dosing tests, measuring free chlorine residual with a colorimeter to validate dosing accuracy across flow conditions

• 05

  Supported redesign for mass manufacturing and injection molding

RESULTS

• Validated consistent chlorine dosing below taste detection limits across varying flow rates

• Prototypes deployed at kiosks and healthcare facilities in Western Kenya and Bangladesh

• Advanced device readiness toward commercial manufacturing
