Planning for "Hack the Cape Town Water Crisis"
Local Organizer:Stop Reset Go
When: Kickoff event: One weekend, sometime between Dec 2017 to May 2018
1. day 1: situational analysis
2. day 2: brainstorming solutions
Period between Hackathon 1 and 2
1. Build prototype
2. Test prototype
Hackathon 2 (Loughborough University Institute for Design Innovation)
day 1: prototype selection
day 2: rigorous analysis and refinement
Where: Cape Town Science Centre and possibly Johannesburg and Durban Science Centre (TBD)
Why: Cape Town is suffering a major water crisis. As of Dec 2017, level 6 restrictions and 87 litres of water/day for residential users. The city is developing large scale infrastructure projects but the city is still at risk of reach a zero water day by May 2018. This hackathon is an open source event to test the potential for the commons to play a role in solving challenging realworld problems through the use of open digital collaboration, circular design commons and cosmo-localization.

5. Maker Station
Future Events: The hackathon is actually an ongoing series of hackathons. Real, practical and scaleable manufacturable solutions cannot be designed and built in one weekend, but requires a sustained effort.
If successful, we will hold a multi-city "Hack the Global Water Crisis" event, especially targetting all water stressed cities around the globe.
The first hackathon in the series is a weekend for situational analysis and brainstorming. Product development objectives are defined including:
- define design targets/specifications (including practical timelines)
- progress trap analysis
- scenario planning using urban footprint/urban regional and planetary boundaries
- circular design/materials
- define R+D roadmap
- define, source and allocate project resources
- develop phase 1 prototype
- test prototype and feedback
- iterative design and testing
- industrial design
- local supply chain
- production funding
local, community production considerations
1. MuSIASEM multi-scale Water-Energy-Food nexus framework - develop grammar
2. cosmo-localization: Design global, Make local - the aim is to create a global design commons of open source circular water technologies. We are aiming for community level manufacturing with lowest possible cost, while retaining a high quality standard, and all designs available for download to start local, community manufacturing that contributes to the local economy.
3. encouraging the formation of a global network of "Global Ecoshops", local innovation / peer production hubs that are cooperatives that produce goods and services for themselves and sell into the local marketplace to raise self-sustaining capital
4. using urban and regional planetary boundaries to guide development within doughnut economics
5. using urban footprint open source software to perform scenario planning to measure urban impact and ensure doughnut eocnomics is not violated.

Water Loop water reuse technology
Water Loop is open source technology developed by Jason Selvarajan and his team in Finland. Jason has participated in past OSCEDays. The waterloop technology holds great promise to dramatically reduce water footprint. The showerloop website claims that a full waterloop system can reduce residiential water consumption from 120 L/day to 20 L/day. Our challenge will be to explore the waterloop technology with the aim of pushing the envelop of circular design to reduce cost and make waterloop an easy-to-install and low cost system accessible to everyone. It may require forking the hardware versions into many branches such as:
- middle income
- low income
- individual residence
Constructed wetlands can clean and filter water that can then be reused for irrigation or for other residential use.
Dietary Change to flexitarian diet
Meat has such a high water footprint that even a slight reduction of meat in personal diet can have a profound effect on water consumption.
Water harvesting technologies
There is a plethora of distributed water harvesting technologies that can be built to serve an individual home or an entire community including:
- passive air condensation technologies (fognets)
- passive underground condensation technologies
- rain harvesting
Refurbishing discarded and used electronics / cellphones
Micro-controllers, while affordable to middle class families, are an exotic item for low income families. Hence, we recommend another OSCE project to complement this, the repurposing of discarded cellphone technology.Many discarded cellphones have perfectly good electronic hardware and hundreds of millions are discarded annually. Could we repurpose these to serve as microcontrollers for embedded applications? When we compare the true cost of throwing away perfectly good electronics compared to purchasing even low cost open source hardware like Arduino or Raspberry pies,
