Flood risk asset management and asset performance in the Greater Wellington Region, George Bowman, Greater Wellington Regional Council
As part of its strategic asset management and continuous improvement, the Flood Protection Department of the Greater Wellington Regional Council has advanced its processes in flood risk asset management. This paper discusses a comprehensive, risk-based framework that has been developed to assess the overall performance of flood protection assets, in relation to required service levels and standards, whilst considering the potential risks posed to the community. Methodologies used and outputs achieved are discussed and presented, respectively, whilst insight is offered into continual improvement moving forward.

George has 3 years experience, having previously worked in the UK as a Flood Risk Management Officer.
Behaviour – a key challenge for our infrastructure
Hayley Tregoweth, WSP Opus
A key way to change people’s behaviour is to change what motivates them. This presentation discusses how our personal views affect our decisions and gives examples of processes already in place at an industry level that help to align our behaviour with community goals, including NZTA Greenroads certification, MauriOmeter and the Infrastructure Sustainability Council of Australia’s IS rating tool. It introduces an idea of a new model called PRISE which considers People, Resilience, Innovation, Sustainability, Environment, with the aim to encourage fundamental changes in behaviours, at every level of society, including the individual, to benefit our communities
Hayley has 6 years full time experience. She joined Opus as a cadet in 2010 completing the NZDE while working full time for three years. Since 2013 she has completed a Bachelor of Civil Engineering while working part time with Opus.Her experience includes working overseas designing gravity sewer systems in Fiji. More recently she has been involved in a large pump station and rising main design for a New Zealand Prison, and three waters investigation and design for a number of other correctional facilities.
Advances in concrete product technology
Ali Mobeen, Hynds Pipe Systems
In recent years manufacturing of concrete products has been affected by alternative materials. To combat this concrete product and manufacturing technology needs to advance.
Restructuring of the concrete product industry has continued at pace in many countries, largely accompanied by the increase of production capacity; in many cases market players with substandard product quality have been forced out of the market. However, this consolidation of markets has led more to price competition on a company level than to quality competition on a product level. These conditions would tend not to support the growth of the industry and potentially favour suppliers of alternative materials.
For concrete products to retain growth in the market, it needs to evolve using new technology and cost-effective manufacturing processes.
This paper illustrates how Hynds are using new technology to increase efficiency and quality of concrete products and how they will be introducing this in New Zealand.
Mobeen Ali is the Concrete Drainage Products Engineer for Hynds Pipe Systems Ltd and has been working for Hynds for over 4 years. Starting in the Graduate program, he has gained experience working in many parts of the business and has progressed to manage the Hynds Drainage product range.
For the last three years Mobeen has spent the majority of his time educating the drain laying industry on the correct installation of Concrete Pipe. So far, he has helped to train over 750 people nationwide from Whangarei to Invercargill.
In the last year Mobeenâs time has been spent on the new Hynds Concrete Factory located in Pokeno where he has been working with key council members to promote the new technology and products that will be available in the upcoming years.
What does wastewater system resilience look like?
Behrooz (Bruce) Balaei, WSP Opus
Failure of wastewater systems not only causes difficulties for the residents and critical users, it but also can have adverse impact on the environment. This paper outlines a framework to address wastewater resilience based on its robustness, rapidity, and contingency measures. A case study is presented discussing the application of this framework to Wellington’s wastewater system. Wellington’s wastewater system vulnerability was assessed. Pipes and pumpstations were ranked based on the combination of their vulnerability and criticality in terms of the number of user being served. Contingency measures were proposed for critical pipes and pump stations to minimise the adverse impact of wastewater overflow on the community’s health and environment. The framework provided an insight into the resilience of existing network and enabled Wellington Water to prioritise their renewal projects to enhance resilience cost-effectively. This framework can be utilised by other local authorities to foster their 3-water resilience under limited budget.
Behrooz is a Water Asset Management & Resilience Engineer at WSP-Opus. He has 9 years of experience in the disaster management field focusing on infrastructure resilience, damage estimation, mitigation planning, risk reduction, and asset management. He studied his M.S in Disaster Management at the University of Tehran in Iran. Having worked at the Tehran Disaster Mitigation and Management Organization (TDMMO), he has been to several disasters and gained a wealth of experience. Behrooz has been working on water supply systems resilience to determine the technical, organisational, social, economic, and environmental factors which affect water system functionality after an earthquake in his PhD journey.
Learning from our past to navigate our future
Pam Wilson, Calibre
There are many different perspectives on what reform means for the communities that we live and work within. Collectively we are navigating a pathway through reform in a manner that is not dissimilar to the pathways that we may navigate individually in our own careers. We identify goals to strive towards and we adapt our career paths as we develop and react to the challenges and uncertainties of what the future of our industry looks like.
We each have different perspectives that may shape how we adapt to future reform. Should we be connecting the dots of our own pasts in order to put new perspectives on how we collectively move forward on the journey of reform?
