Frequently asked questions

What does an environment engineer do?

An environment engineer operates and maintains a plant's pollution control systems and runs environmental monitoring. They run the effluent and sewage treatment plants, monitor emissions and effluent, manage waste, and keep records for compliance. They keep discharges within limits every day and support consents and inspections with solid data.

What qualifications do you need to be an environment engineer?

Most environment engineers hold a degree or diploma in environmental engineering, and a chemical engineering background is often accepted. Employers look for knowledge of effluent and sewage treatment plant operation, environmental monitoring, waste management and safe chemical handling, plus the ability to keep accurate records for statutory compliance.

What is an effluent treatment plant?

An effluent treatment plant, or ETP, treats the wastewater a factory produces so it meets discharge norms before release or reuse. It uses physical, chemical and biological processes to remove pollutants. An environment engineer operates the ETP, adjusts the process to keep output within limits, and keeps records that prove compliance.
