Suki Singh


Suki is a people orientated Civil Engineer with a high degree of proficiency across Sewer and Water Design. Suki’s attention to detail and his dedication to achieving the best outcome is well received from developers, who appreciate his friendly and approachable nature.

His years of experience in the Hunter Region as a Civil Engineer positions Suki to fully understand the needs of his clients.

Suki began his career working as a Traffic Controller for a few months after completing University before moving into surveying, drafting and administration for a short period.

Suki then worked as a sewer and water designer, eventually becoming the lead designer & acting manager of sewer & water projects.

Suki joined WDG as a Civil Engineer and currently works on civil infrastructure design (stormwater/roads/erosion and sediment controls) with the team. Suki also assists with sewer & water design from time to time.

Suki loves working at WDG because he enjoys working along side of some very experienced and intelligent team members who are open about collaboration and focus on constantly improving.

It’s encouraging to work in this type of environment that also helps Suki to grow as an engineer.

Suki also likes the work culture and office banter, despite being very hard workers, it is still a relaxed office environment and everybody is very friendly and jovial.
