Open-Source IoT Framework for Mobile Household Water Reuse System

Humanitarian response often addresses the basic human needs which include safe, sanitary, hazard free environment. From the war torn countries to remote communities, untreated household waste water creates living conditions directly affecting human welfare. We present an IoT enabled, semi industrial, mobile waste water treatment solution targeted for communities in remote sub-Arctic regions without a centralized sewer system or a waste water treatment facility. The open source hardware and software platforms were implemented on an Arduino Mega and Raspberry Pi to operate a household water reuse system. The water reuse system was developed as part of the Alaska Water and Sewer Challenge to address a cost effective alternative to piped water and sewer service in unserved remote Alaskan Communities. The semi-industrial water treatment system was controlled using the internet enabled Arduino Mega and Raspberry Pi components-off-the-shelf (COTS) that allowed for both on-site and remote control. While implemented as a proof-of-concept of a treatment system to evaluate existing waste water technology, the production model can take full advantage of the internet of things concepts that would allow for proactive maintenance scheduling, optimized treatment time to meet available community electrical loads, and remote troubleshooting and operation to name a few.
