Water network models are an established tool for assessing system performance and identifying improvements. The primary measures of whether a water service is meeting customer requirements are water quality, water pressure and the number of occasions when the supply is interrupted.
Waterco team members have considerable experience in the use of network modelling, from the original non graphical methods to the current ‘all mains models’ and have been involved in a range of projects where this approach has been adopted for clients including:
- United Utilities (UU)
- DwrCymru Welsh Water (DCWW)
- Severn Trent Water (STW)
- Anglian Water (AW)
The team also has experience in the use of models to achieve various outcomes including:
- detailed zonal studies – all mains
- water main rehabilitation – all mains
- source to tap models – strategic models water quality – all mains
- pressure management – all mains
- water resource balancing – upstream losses
- surge analysis
Waterco has also worked with modelling packages internationally including with Watnet, Wesnet, Ginas5, EPANET, Strumap, SynerGee, Infoworks and Aquis. We ensure that our Design Department is kept fully up-to-date with industry developments and are always on hand to assist during the design and approval process.
