Aaron Sanders

Designer Manager – Waste & Water Infrastructure, and Civil

Aaron undertook a Cert III in Plumbing & Services after finishing year 10 moving onto completing his Cert IV to move into the hydraulic design sector where he began his career at WDG and then WPFD.

At the time the company consisted of a team of four, where Aaron began as a hydraulic design consultant working on high rise developments, schools and health facilities and HWC, Mid Coast Council Assets.

Aaron went on to study and attain entry into university where he began a Bachelor of Civil Engineering Degree. With the support of Shaun and the WDG team Aaronhas been able to work full time whilst completing a degree and continue to progress in his career where he has seen the company grow over throughout the past five years from the initial WPFD team of four to the now WDG team of fifteen strong and becoming a part of the infrastructure management team.

Aaron loves working at WDG because of  the culture and values it stands for and whom has supported and encouraged Aaron to further his education and development, and has rewarded his hard work.

Aaron enjoys working in a multidisciplinary company where he has gained experience across a wide variety of fields and projects and as the company has continued to expand, Aaron has been supported in progressing his career with a well-established strategic planning framework and mentoring.

The team take their responsibilities seriously but not themselves creating a great inclusive work environment.

At WDG we are always looking to be innovative and improve our systems and Aaron has had the opportunity to participate in the development of WDG systems from 2D CAD to 3D design and modelling.
