Water distribution networks

Network modelling

The process of building, verifying and operating network models of distribution systems provides valuable insights into operational practices.

Halcrow is experienced in data collection and model building using the latest simulation network analysis programmes.

As framework consultants to several major water utilities, Halcrow has experience with the following software packages:

WESNET, INFOWORKS, STONER/SynerGEE, EPANET, AQUIS and WATNET hydraulic modelling packages.

ARCVIEW, INTERGRAPH. SUS2000 and MAPINFO. These GIS packages are used to provide many of the physical attributes required from a distribution system to establish a base hydrualic model and for future updates of network models.

STRUMAP. This package is used to convert GIS data into a format suitable for direct input into various hydraulic models.

Halcrow have also used Strumap as a GIS system together with HARP, its built-in hydraulic model.

Halcrow uses models in many ways to improve operational performance and to identify improvements and reinforcements to the distribution system.
