Benchmarks

Wolf-Cordera Ranch

Colorado Springs Utilities, currently serves a population of about 370,000 persons with the population projected to increase to about 520,000 persons by year 2030. Several master planned developments within the City require system optimization to determine the best engineering solution in meeting established design criteria while at the same time minimizing capital costs

EXNET

This benchmark water system has been set up by the Centre for Water Systems of Exeter University as a realistic challenging problem. The aim is to determine the most economically effective design to reinforce the existing system to meet projected demands as a network

Gessler 1985

This pipe network has been studied by Gessler 1985 and Simpson et al. 1994. The objective of the problem is to determine the most economically effective design for addition of five new pipes (6, 8, 11, 13 and 14) to the existing system, and duplication or cleaning or leaving alone three of the existing pipes (1, 4 and 5).

Expansion of existing water distribution systems

Anytown Water Distribution Network

The objective of the Anytown network problem is to determine the most economically effective design to reinforce the existing system to meet projected demands, taking into account pumping costs as well as capital expenditure.

New York water supply system

The objective of the New York Tunnel (NYT) problem is to determine the most economically effective design for addition to the existing system of tunnels that constituted the primary water distribution system of the city of New York.

D-Town Water Distribution Network BWN-II

The objective of the D-Town network problem is to determine the best long-term design improvements given projected future water demand and development of a new area. This analysis takes into account capital and operational costs, greenhouse gas (GHG) emissions and water age.
