North East Water has appointed Mott MacDonald to investigate the performance of sewerage systems in Yarrawonga, Wodonga and Wangaratta in north east Victoria, Australia.
Mott MacDonald said that the project aims to understand the current and anticipated future performance of the sewerage systems under the influences of urban growth and wet weather.
The global consultant said that it will install 46 flow monitors and 12 rain gauges to monitor flows within the system over a 12 week period. It said the results of this would then be used to model growth related to dry weather flows and wet weather flows across a range of average recurrence intervals.
Using MikeUrban software and the H2Kn0w-how specialist hydraulic assessment tool developed by its in house team, it will analyse flow data to identify any likely issues with inflow, infiltration or other hydraulic issues. This will work towards building, calibrating, and master planning the entire flow modelling stage.
Mott MacDonald project director Peter Stephens said: “The models will be used to develop options that will accommodate future growth and reasonable wet weather flows in the sewerage systems. The projects identified will be put forward for design and construction, mainly over the next five year planning period from 2017-22.”
The project is expected to be completed in the middle of 2016.
