Description

Typical Network Design

Designing a water distribution scheme means locating and sizing each component of the network. Which source do we use? Where do we place our ESRs in terms of location and elevation? What should be their capacity? What should be the diameter of the pipes? The aim of the design is to satisfy the water demand of each village and at the same time minimize capital and/or operational cost of the design.

In the first iteration of the system, pipe diameters are optimized given the location and demand of the ESRs. ESR selection (location, height, capacity, and which nodes it serves) is also now integrated into the optimization.

Pipe Diameter Optimization

Finds optimal diameters for every pipe segment in branched or looped networks under pressure constraints.

ESR Selection

Selects ESR location, height, capacity, and which nodes each ESR serves as part of the optimization.

Pump & Valve Support

Models pumping stations and pressure-reducing valves for complex multi-source and multi-zone schemes.

ILP Solver Engine

Uses Google OR-Tools and COIN-OR Branch and Cut (CBC) for rigorous, cost-optimal solutions.

Linear program interface used: Google OR-Tools  |  Linear program solver used: COIN-OR Branch and Cut (CBC)
