A Golden Opportunity to Uncover and Maintain Constructed Stormwater Wetlands 

 

As South Australia moves through another dry period, many of our constructed stormwater wetlands are experiencing naturally low water levels as part of their regular drying cycles. While this may seem like a quiet time for these important assets, it’s actually a critical window of opportunity for asset managers and maintenance teams. 

Uncovering Your Hidden Assets 

When wetlands dry, they reveal more than just their muddy bottoms—they uncover valuable infrastructure that may be hidden or submerged during wetter months. This is the perfect time to ask: How low does your wetland go? And more importantly, what can you see now that you couldn’t before? 

With lower water levels, you have the chance to: 

• Get up close and inspect asset components like inlet and outlet structures, trash racks, headwalls, sediment basins, and sub-surface infrastructure. 

• Ensure these components are recorded on your asset register. If they’re not, now is the time to document, photograph, and update your records. 

• Perform necessary maintenance while access is safer and easier. This includes removing built-up sediment, repairing eroded banks, checking for structural damage, and managing invasive plant species. 

Why Now? Following the Natural Cycle 

Constructed wetlands are designed with drying cycles in mind. These periods are crucial not only for ecological balance but also for practical maintenance and inspection. Scheduled drying gives teams a reliable timeframe to plan for site visits, audits, and restoration work. 

Act Now 

Dry periods are not just a seasonal inevitability—they’re a strategic asset management moment. If you’re responsible for stormwater assets, plan a visit now. It’s your best chance to uncover, understand, and enhance your wetland systems. 

Is your asset register ready for a refresh? Your wetland might be telling you it’s time.
