When New Plymouth District Council (NPDC) recently upgraded their wastewater treatment plant’s headworks, they needed an advanced hydraulic model to better estimate the types of headlosses they would experience under various flow conditions.
Challenge
When New Plymouth District Council (NPDC) recently upgraded their wastewater treatment plant’s headworks, they needed an advanced hydraulic model to better estimate the types of headlosses they would experience under various flow conditions. They approached Lutra to help develop such a model.
With Covid-19 level-4 lockdowns in full force in New Zealand, Lutra collaborated remotely with the team at NPDC to confirm suitable approaches for the hydraulic model structure and a method for data collection.
Solution
Together with the team at NPDC, Lutra were able to develop and calibrate a hydraulic model using operational data from site and online readings recorded by the plant PLC.
The outcome was a representative model which accurately predicted the hydraulic capacity and resulting headloss of the headworks at various operational conditions.
The model is now a tool which can be used to update plant documentation and allow for greater insight into the anticipated performance and capacity of the new system.
