WaterWise: Smarter Water, Smarter Cities

 

1.The problem

Cities around the world waste millions of liters of water every day.

  • Leakages drain resources before they reach homes.
  • Unequal distribution means some neighborhoods face shortages while others get oversupply.
  • Outdated systems rely on fixed schedules and manual monitoring.

With urban populations growing and climate change pressuring resources, water distribution inefficiency has become a critical global challenge.

 

2.The Solution

WaterWise: A smart, affordable, and scalable water management system that uses mathematics and optimization to ensure fair, efficient, and sustainable water supply.

Unlike costly smart city solutions, WaterWise adapts to existing infrastructure, making it accessible even in developing regions.

 

3.How it works

  • Model the water network as a graph (nodes = tanks, edges = pipes).
  • Apply Linear Programming & Network Flow Optimization to minimize losses and balance supply.
  • Run simulations using Python or MATLAB to test different scenarios like peak demand or pipe failure.
  • (Future-ready) Integrate with IoT sensors for real-time leak detection and adaptive control.

 

4.Key features 

  •  Fair distribution – every community gets its share.
  •  Cost-effective – works with existing pipelines and tanks.
  •  Leak reduction – optimized flows reduce wastage.
  •  Scalable – from small towns to mega cities.
  •  Future integration – IoT-enabled, AI-driven monitoring.

 

5.The Model

  • Revenue Model: Subscription-based service for municipalities.
  • Impact Model: Communities save water, municipalities save costs, environment benefits from conservation.
  • Growth Model: Start with cities in water-stressed regions → expand to global smart city networks.

 

6.Final Pitch

    WaterWise is not just a water management tool—it’s a step toward smarter, greener, and fairer cities. By turning mathematics into impact, we ensure that every drop counts. WaterWise: because smarter cities start with smarter water.
