About Us

Our History

SEEC was established in August 2007 by Director Andrew Macleod and former Director Mark Passfield. SEEC offer a unique combination of expertise in environmental engineering, ecosystem management, geomorphology and soil science. We have a particular strength in stormwater quality, water sensitive urban design (WSUD) and erosion and sediment control. 

We offer prompt, professional, cost-effective solutions from our interactive and flexible team who use the latest design and modelling software.


We have an enviable reputation for professional integrity and accuracy in all of our work. Government agencies and Councils recognise that we don’t cut corners or try to sneak through sub-standard work. We place very high expectations on ourselves in terms of technical proficiency and getting it right first time, and our clients can expect nothing less.


SEEC staff have years of experience in environmental management in both the public and private sector. We know how to meet regulatory requirements and develop environmental solutions, and we know who to call in government to discuss your site.


We seek to provide a positive outcome in a timely manner for our clients. A consultant who gets it right first time ultimately saves you time and money. We work alongside you, listen to you, and provide advice where necessary, all with the ultimate goal of giving you a great service and a positive outcome.


We at SEEC believe that great service includes a great product, and a great experience. When utilising our services, it’s our job to ensure that our product meets your requirements. We also want to provide a great experience for our clients – friendly and reliable staff, plain-English communication, honesty and integrity in all of our dealings.
