Stormwater detention tank inspections are a crucial part of managing flood risks, ensuring system functionality, and maintaining compliance with local regulations. Whether for a residential subdivision or a large commercial development, routine inspections help ensure that your stormwater system performs as designed.
What are Stormwater Detention Tanks?
Stormwater detention tanks are designed to temporarily hold runoff during storms, preventing flooding and easing pressure on public drainage systems. These tanks play a vital role in stormwater systems across Greater Sydney and New South Wales, especially in areas with high rainfall or rapid urban development.
Why Regular Inspections are Necessary
Inspections ensure the tank operates efficiently and safely. Over time, sediment, debris, or structural damage can reduce tank effectiveness or lead to environmental and compliance issues. Regular inspections help:
- Prevent flooding and waterlogging.
- Eliminate mosquito breeding and health risks.
- Verify the integrity of drainage systems.
- Ensure OSD tank maintenance is up-to-date.
- Meet requirements from local councils and stormwater guidelines.
What Happens During an Inspection?
Licensed and experienced professionals assess key elements of your tank and its surrounding system. A typical inspection includes:
- Checking for structural defects.
- Verifying that inlets, outlets, and filters are unblocked.
- Evaluating overflow and bypass systems.
- Testing water flow and retention function.
- Assessing insect control features.
- Reviewing downstream systems and stormwater units.
- Ensuring no excessive debris, vegetation, or mosquito breeding grounds.
If your detention tank supports potable or fire water supply, more specialised maintenance may be required.
Inspection Frequency and Reporting
It is generally recommended to schedule inspections annually, or as specified by your asset management plan or development consent. For commercial sites and public amenities, inspections may be required more frequently.
After each inspection, you will receive a detailed report including:
- Photos of identified issues.
- Recommendations for professional maintenance and operations.
- A maintenance schedule for follow-up.
- Compliance assessment with AS and council standards.
Who Should Perform the Inspections?
Choose a team with experience in detention tank inspections and stormwater system management. Look for:
- Proper licensing and certifications.
- Understanding of OSD tanks and drainage design.
- Experience with subdivisions and infrastructure.
- Capability to perform repairs if required.
