We have lived in Mumbai, Bangalore and Pune. Some of India's biggest cities. We've witnessed problem of usable water availability. WRC concept attracted me as it promised transparent and open solution to water reuse and takes care of penalties for those who fail to comply. And this all by design. Also we are interested in social impact blockchain technology can have on daily life.

In slides attached and walk through video, we have mentioned following points:

  • What it does
  • How we built it

Recommendations given by us

  • Match water usage data with power consumption information
  • Secure the data using key based hashing
  • Test volume of overall discharge to ensure that the users are not mixing plain water to improve quality

Challenges we ran into

The domain is new and this was first time with blockchain, setting up Hyperledger Fabric and creating SmartContract (known chaincode) was bit challenging.

Accomplishments that we're proud of

We as a team worked together for the first time. Akshay did ML using Spark ML. Ashish setup Hyperledger Fabric. And as a team we tried to address wide spectrum of solution for concerned problem statements.

What we learned

  • Hyperledger Fabric
  • Spark streaming and ml
  • Creative solutions to real life problem of device and data tampering

What's next for WaterCoin

We will try to work on ML models and try to fine tune our process. Also if we get funding for the project, we can actually implement the solution. From IoT device design to backend to deployment in real water reuse plants across industries.
