For Science Hack Day 2019 in San Francisco, we built a water filtration system to turn dirty water into a drinkable, clean, sanitary fluid, using local supplies and an optional electronic turbidity measurement system.

We won the prize for "Best Demonstration".

APIs, data and tools used

  • Reclaimed plastic bottle, paper or cloth, sand, gravel, charcoal.
  • Arduino (I had an ESP8266 and used it, but you should find the most basic and cheap Arduino available).
  • 1 x red LED
  • 1 x green LED.
  • 5 volts power bank (a solar cell and a condenser should be sufficient, as the power consumption is very limited)
  • 1 x photocell

Possible improvements

  • Enclose the electronic and the solar cell into a ring that can fit many bottle sizes
  • Manage the total cost to be less than $0.90
  • Design an undestructible To-It-Yourself instructions sheet to create and use the water filter
  • Ask for production and distribution help from an NGO like the Billa And Melinda Gates Foundation, the Red Cross, etc.
  • Distribute wherever unsanitary drinkable water supply is an issue
