Environmental engineer video

After the Maldives I went to Liberia for 12 months also with the Red Cross and the role that I played over there was quite different from when I was working in the Maldives. Instead of installing desalination plants we were dealing with more basic water and wastewater treatment, so like, you know, hand dug wells, deep bores, as well as latrines, so it was just really basic water supply and basic waste treatment, and when I came back and there was an opportunity with Watercare, which I thought would fit in very well with the next step in my career, so I joined Watercare, and that was seven or eight years ago, and I’ve been with Watercare ever since.
I've been involved in two projects so far. One is a landfill and the second one is the Central Interceptor project and both of them are large in terms of scale and unique in terms of is you know its design and its construction.
The century interceptor is a 13-kilometre-long wastewater pipeline. It's one of the biggest projects that Watercare has ever done and basically it takes flows from Western Springs and gravity feed it all the way down to Mangere Wastewater Treatment Plant. This is a billion-dollar project and it'll take six years to complete from start to finish.
In some ways it's very similar to what I used to do when I was overseas in terms of the level of engagement and stakeholder engagement and community consultations but at the same time it's very different in terms of the technical difficulties and the complexities. When construction begins we'll be using a tunnel-boring machine very similar to what we used for Hobson tunnel.
The project is currently in its design state and so some of the design includes you know further investigation, such as geotechnical investigations. We've also carried out some typographic surveys just to make sure that we understand the places where we're going to be working and understand where the connections are.
There are three main key drivers for Central Interceptor project. First one being to replace part of the Western interceptor main lead in Manukau, second key driver is to provide for growth, and the third key driver is to protect the environment.
The manager of this huge project is David Warden. He’s also a bit of a mentor for me. He’s the kind of person that is very easily approachable. I use him as a bit of a sounding board when I get stuck with technical issues, as well as in terms of my career as well.
Part of being involved in such a large project is obviously to engage with different stakeholders, be it internal stakeholders or external stakeholders. So within Watercare the CI team actually work closely with the communications team, the property team, their planning and strategy team, as well as the service delivery team.
For me it's all about the people that we work with. I work with a fantastic group of people – the team of engineers within this same project. They're really supportive and they're really motivated and we all have the same objectives and that is to do our job and do our job well.
I'm Bernice Chiam and I'm proud to be a principal design engineer for Watercare.
To become an environmental engineer you usually need to have a Bachelor's degree in engineering.
You can complete a four-year Bachelor of Engineering or Bachelor of Engineering with Honours, specialising in environmental, civil or natural resources engineering.
A tertiary entrance qualification is required to enter further training. Useful subjects include physics, chemistry, maths, geography, and construction and mechanical technologies.
Environmental engineers need to be:
- practical and logical, with good problem-solving skills
- accurate, with an eye for detail
- good at planning and organising
- good communicators
- able to work well as part of a team
- able to work well under pressure and meet deadlines.
Useful experience for environmental engineers includes:
- environmental or outdoors work.
Bachelor of Engineering (Hons) graduates may apply to gain registration as a Chartered Professional Engineer (CPEng) with Engineering New Zealand.

What are the chances of getting a job?
Shortage of environmental engineers
Opportunities for environmental engineers are good due to a shortage of skilled workers.
Environmental engineer appears on Immigration New Zealand's long-term skill shortage list. This means the Government is actively encouraging skilled environmental engineers from overseas to work in New Zealand.
According to the Census, 357 environmental engineers worked in New Zealand in 2018.
Best job chances in the North Island
Job opportunities for environmental engineers are increasing as the Government invests in infrastructure in the North Island.
Auckland and Wellington in particular require civil infrastructure engineers with experience in stormwater systems.
Changing environmental rules mean increasing demand for engineers
New environmental standards mean local authorities are upgrading their stormwater infrastructure. Environmental engineers are needed to help design and supervise this work.
Demand for environmental engineers to work on stormwater systems is likely to grow as more frequent, severe weather events cause increased flooding.
Environmental engineers are also needed to help monitor the environmental impact of construction and infrastructure projects.
Types of employers varied
Environmental engineers may work for a variety of employers, including:
- private engineering consultancies
- regional and local government authorities
- infrastructure and utility companies such as roading and electricity companies
- government agencies such as the Ministry for the Environment.
