Overview

Wellington Water Limited is seeking professional hydraulic model services from consultants to calibrate and validate the Pinehaven catchment. The deliverable is an updated model that can be used with an understanding of its limitations along with an understanding of the risk of using the model. Any further investigations will be clearly identified that would improve the model and/or reduce the risk of application of the model.
The model will be used for a systems performance assessment, and the development of a growth strategy and compliance with containment standards for the benefits of the community.
The goal is to create a robust hydraulic model that can be used to provide a resilient and efficient wastewater network for the community now and into the future.
