Sustainable Urban Communities



Off-grid blockchain-linked hubs producing clean water, food, and electricity

Team Lead

Solution Summary

Water systems are growing old and inefficient. A select few providers have a monopoly on water services, and aging pipe networks are expensive and slow to clean and repair—which deteriorates water quality and accessibility over time. Waterig will counter this by gradually decentralizing urban water, energy, and food resources with a network of hubs and incentivized contributors.

These hubs harvest renewable solar and waste energy, and then use this energy to capture and treat water or power nearby food facilities. To further support decentralization, Waterig’s network is backed by a blockchain system that supports crowdfunded hub micro-ownership and facilitates the exchange of surplus energy, water, and food.

Market Opportunity

  • Centralized water systems have a higher leakage rate, with 15 to 20 percent of total consumption wasted because of poor pipe infrastructure.
  • 70 percent of countries reported to UN Water that tariffs do not cover the costs of operation and maintenance of water services, risking declining service levels.
  • Service providers have a monopoly on water, with a global cost of water and wastewater management of US $540 billion per year.
