Colin McLeod

Colin McLeod
Maroondah City Council

Colin is a Civil and Infrastructure engineer who started his career working as a Civil Structural Engineer focusing on housing developments and drainage design. During this time, Colin has developed skills relating to foundation and construction; his passion however, was always with water and its interactions with the environment.

Colin is currently working with the local government as a Drainage Engineer, expanding his knowledge and skills of flood modelling and project engineering. His role consists of assisting developers to design proposals that reduce flooding across municipalities, whilst also identifying areas for draining improvements and water sensitive urban design. Through his work, Colin hopes to continually enhance surrounding communities through developments of new innovative solutions that will reduce adverse impacts on waterways and ecology surrounding those waterways.

Tracey Pham

Tracey completed a Bachelor of Engineering (with honours) at Monash University, and worked for a short time at Western Water as a project manager. During her undergraduate degree, she investigated the cost and benefits of several stormwater harvesting projects in Melbourne. Tracey finished her Master of Engineering (Research) thesis titled “The Effect of Vegetation in Stormwater Biofiltration Sytems”. This project taught her the importance of persistence, optimism and patience to project delivery.

Tracey has also had various roles in the Civil Engineering world. She taught stormwater management to undergraduate students, and assisted PhD students with field or lab work as a Research Assistant. Tracey was a stormwater consultant at Cardno for three years and is now working at Afflux Consulting. The work varies depending on project and client requirements, however they primarily consist of:

  • Devising stormwater and flood management solutions
  • Drainage, flood and water quality modelling (primarily using 1D and 2D XPSWMM, MUSIC, TUFLOW)
  • Liasoning with clients and relevant authority
  • Flood mapping (MapInfo)
  • Stormwater Risk asessment
