Process & Hydraulic Design Engineer

Water and Wastewater Treatment

Innova Water Pty Ltd

Portside, Brisbane QLD

Indicative salary: $135,000–$155,000 + super

Design complete treatment solutions and see them through to successful operation

If you are already a capable process engineer but feel your current role is becoming too narrow, this may be the prospect you have been looking for.

Innova Water is a specialist process and hydraulic engineering consultancy delivering water and wastewater infrastructure projects across Australia’s east coast.

We work closely with contractors, councils, utilities and engineering partners to develop practical treatment solutions that can be successfully procured, constructed, commissioned and operated.

Our engineers remain involved throughout the project lifecycle. You will complete process calculations, develop PFDs and P&IDs;, select equipment, prepare control documentation, coordinate supporting disciplines and work directly with clients and suppliers. You will also have opportunities to support procurement, construction, commissioning, performance testing and process optimisation.

This is an opportunity to remain technically hands‑on while developing into a complete project engineer and, over time, a project and business leader.

About the Role

This is first and foremost a hands‑on process and hydraulic design position.

From commencement, you will be expected to personally produce the essential deliverables of process engineering, including:

- PFDs and P&IDs;

- Mass, flow and chemical balances

- Process and hydraulic calculations

- Equipment sizing and selection





- Equipment, instrument and valve schedules

- Design reports and Basis of Design documents

- Functional descriptions and control philosophies

- Alarm and interlock schedules

- Technical specifications and procurement documentation

- Commissioning plans and procedures

You do not need experience across every treatment technology or equal strength in both water and wastewater.

You may, for example, have strong experience in conventional water treatment, membranes, biological treatment, industrial water, chemical systems or equipment‑package design. What matters is that you already possess sound process‑design fundamentals and can apply them to unfamiliar systems with appropriate support.

During your first 6–12 months, the development focus will be on unfamiliar treatment processes, Australian utility requirements, multidisciplinary coordination and increasingly independent project delivery. It will not be on learning the fundamentals of process‑design documentation.

What You Will Work On

Projects may include:

- Water and wastewater treatment plants

- Recycled‑water facilities

- Pumping stations and hydraulic systems

- Chemical storage and dosing systems

- Filtration and membrane systems





- Biological treatment systems

- Solids‑handling systems

- Treatment‑plant upgrades and process optimisation

Your responsibilities will extend beyond conventional design and may include:

- Concept development and optioneering

- Tender‑stage and early contractor involvement

- Multidisciplinary design coordination

- Equipment evaluation and technical procurement

- Client and supplier engagement

- Construction‑phase technical support

- Commissioning and troubleshooting

- Proof of Performance Testing

- Water‑chemistry testing and process optimisation

About You

You are already capable of developing technical process deliverables, not simply coordinating or reviewing work produced by others.

You can explain the engineering basis behind your calculations and design decisions. You communicate professionally with clients, suppliers, contractors and other disciplines, and you want greater responsibility without moving away from technical engineering.

You will be able to demonstrate:

- A recognised degree in Chemical, Process, Environmental or a closely related engineering discipline

- Approximately 4–10 years of relevant experience, with flexibility for an unusually capable candidate

- Hands‑on process‑design experience in water, wastewater or a sufficiently related process industry

- Personal authorship of PFDs, P&IDs;, calculations and design reports

- Experience sizing and selecting process equipment

- Experience preparing functional descriptions, control philosophie
