We challenge participants to create innovative applications using Blockchain, AI & IoT technologies to help solve the world's growing water challenges.

WRC = Wastewater Reuse Certificates



To crowdsource ideas to track wastewater reuse by several entities and incentives the entities that do so.

Problem Statement

Setup smart contracts on wastewater reuse targets between regulators and the focus entities. Capture data using IoT to track contract performance. Store data in a Blockchain to facilitate data transparency and verify compliance with set targets and contracts.

WRC’s is a concept that acts as a digital measure of the quantity of wastewater reused by each entity, subject to the water meeting minimum quality standards.

About the Organisers

This Hackathon is organised by the Maharashtra Water Multi-Stakeholder Platform, which is a public-private-civil society partnership launched through a Government of Maharashtra resolution in May 2017. As a part of this activity, 2030 Water Resources Group (hosted at The World Bank) and the Maharashtra Water Resources Regulatory Authority (MWRRA) are managing a workstream titled “Wastewater Reuse and Management”. 2030 WRG secretariat, along with MWRRA and a key private sector partner - the Bombay Chamber of Commerce and Industry (BCCI) are managing this Hackathon.


Contribute your coding skills to help solve the world's water challenges. Your solution maybe chosen for real-life implementation in the state of Maharashtra and if successful maybe implemented globally in multiple countries.
