Hydraulic Modelling

Wastewater, Stormwater & Rivers

We have the experience and capability to deliver cost-effective modelling. Our team has delivered integrated stormwater models for catchment planning, detailed wastewater system performance models and everything in between. We take a practical approach to modelling. Our work is targeted at achieving the project objectives and effort expended in the right places for the right reasons.

We can use any of the industry standard software packages – XP STORM, Microdrainage, Infoworks ICM, MikeFlood, TuFlow and HEC products.

Resource Consent Processing & Policy Development

The Metis team has supported technical review on stormwater management / flood risk components of more than 700 resource consent applications in the last five years. We bring detailed understanding of best practice international and local approaches to your team.

We can lead development and implementation of planning policy for flood risk / stormwater management and climate change. Our previous work includes a Strategic Flood Risk Assessment for West London (an urban population of 1.5million people).

Peer Reviews

Our senior team can do Peer Reviews in line with the Engineering New Zealand guidelines for any of the services detailed above. We bring international experience and a range of best practice approaches to the Peer Review process. Reviews can be undertaken at the following levels:

  • Concept / Strategic – Confirm the direction of your project and ensure it meets the key objectives
  • Specific – Ensure suitability of deliverables, assess the impact of new factors, test risks or economic viability
  • Regulatory – Confirm that your work follows relevant regulations, codes, standards or guidelines

Case Studies

Newton Park Flood Alleviation and River Restoration Project

The park originally flooded after heavy rainfall causing damage to residential properties around and downstream of the park. Metis gained funding for and designed the Newton Park West Flood Storage Area and River Restoration Scheme.

Seven Kings Water - Flood Mitigation Feasibility Study

Funding was granted to the London Borough of Redbridge to investigate the flood mechanisms and identify potential flood mitigation options at Westwood Recreation Ground on the Seven Kings Water river.

Urban stormwater modelling approaches in NZ and the UK

Between 2019 and 2020 Metis Consultants and Awa Environmental collaborated to deliver eleven large urban stormwater models in the United Kingdom. The case study draws together lessons learned and how NZ / UK could use each other’s experiences – including how the ongoing three waters reforms could benefit from similar approaches in the UK and the implementation of national modelling standards.
