Waste Water Modelling Guidelines

The purpose of these guidelines is to provide good practice protocols for undertaking wastewater (sewer) network modelling in New Zealand. In establishing these good practice protocols, the guidelines aim to progressively improve the development and use of models in New Zealand and consequently the accuracy of modelling results so they can be relied upon when undertaking developing asset management plans, designing specific engineering solutions and assessing environmental effects to support resource consent applications.

The guidelines contain information and recommended protocols on many aspects of wastewater network modelling including: the main types of models available and when to use them, the nature of input data required, and how to get the most accurate results for the level of assessment required. These guidelines have been developed to assist those relatively new to modelling techniques, and those involved in scoping and/or reviewing modelling outputs.
