Hello everyone and welcome to the November edition of “Keep Things Flowing”, the monthly newsletter presented by Storm Water Consulting.

In this month’s newsletter we review a recent SPEL Breakfast Seminar, we answer another frequently asked question and we bring you the latest news from Storm.


SPEL Breakfast Seminar

Earlier this month Jack, Darren, Steve and Cody (pictured below, left to right) attended SPEL’s Breakfast Seminar held in Southbank, Brisbane.

The special guest speaker at the seminar was Professor Carsten Dierkes, from Germany, who spoke of the new Hydrosystem and Hydrochannel products currently being tested throughout Europe. These new devices provide alternate treatment methods for stormwater runoff.

Professor Dierkes also spoke about the considerable difference between the key nutrient removal requirements between Europe and Australia.  European stormwater treatment is heavily focused on the removal of heavy metals (whereas Australia is focused on nitrogen and phosphorous removal). This is largely due to the high number of metal based roofs used in European cities.

The seminar concluded with presentations about three of SPEL’s products, the SpelFilter, Stormsack and Floating Wetlands. Our July 2015 edition of “Keep Things Flowing” presents information about the SpelFilter. Our previous newsletters can be viewed on our website at



Frequently Asked Question


My property is located in an overland flow path, but not located within Brisbane City Council’s Overland Flow Flood Planning Area. Does the Flood Overlay Code apply to any development I do on my block? If no, what overland flow design criteria will I be required to achieve?


If you are not located within the Overland Flow Flood Planning Area then you do not have to meet the requirements of the Flood Overlay Code (providing there are no other triggers). You are however required to meet the principles of common law. That means that you cannot create an adverse impact on a neighbouring properties. For example, you cannot divert overland flow onto a neighbouring property (without consent) and create an adverse impact. You may be liable for any damages caused and could be forced to remove the imposing structure.

It is always best to seek professional advice when unsure if overland flow flooding could be an issue. Despite the fact that the Flood Overlay Code may not apply, it would not be uncommon for a hydraulic engineer to still meet the design requirements of the Flood Overlay Code. The Flood Overlay Code contains many design criteria from the Queensland Urban Drainage Manual (QUDM). QUDM provides design criteria for both safety and sustainability of development in Queensland.

If you are unsure whether your property is affected by overland flow or you would like professional advice on the development constraints associated with overland flow on your block, please contact our office.
