Development And Testing Of Software For The Optimal Improvement Of Water Distribution Networks (1997-2003)

Funding body: Ewan Optimal Solutions Ltd.

Development work resulted in the software programs, GAnet and GAcal, which have been used on commercial projects involving hydraulic model calibration, design of water distribution network reinforcement and rehabilitation schemes and the optimization of level controlled pumping station operation. GAcal has also been sold commercially. Current development work is aimed at integrating GAnet with OpenNet, a library of C++ classes that provide the facilities for modelling water networks.
