Stormwater Treatment Products & Systems
Stormwater Screens & Baskets
Custom-fabricated screens and baskets designed to capture debris and sediment at the stormwater pit before it enters downstream infrastructure.
- Captures rubbish, debris, and coarse sediment at the source
- Helps protect pumps, valves, and downstream treatment systems
- Retrofit-friendly designs for existing pits and drains
- Stainless steel options available
Stormwater Pits
Pre-manufactured stormwater pits with integrated silt baskets designed to capture sediment and debris as part of permanent drainage infrastructure.
- Captures sediment, litter, and gross pollutants within the pit
- Suitable for new builds or retrofit into stormwater networks
- Pre-manufactured options available
- Helps reduce downstream maintenance and cleaning costs
De-Watering Bags
Temporary filtration bags used to reduce sediment and turbidity in pumped water during construction and excavation activities.
- Helps filter silt and sediment from discharged water
- Commonly used during construction, civil works, and dewatering operations
- Suitable for temporary stormwater management on active sites
- Easy to deploy and remove once the work is complete
Weighted Drain Covers
Temporary, surface-mounted barriers used to seal stormwater inlets during spill response and maintenance activities.
- Provides an immediate seal over stormwater pits and drains
- Helps prevent contaminants entering the stormwater network
- Simple to deploy, remove, and store when not in use
- Suitable for clean-ups, washdowns, and short-term works
Systems are selected for Australian site conditions and backed by Trade Enviro’s product-selection and project-support advice.

|---|---|---|
| Risk of spills entering stormwater drains | Weighted Drain Covers | Temporary protection during clean-ups, maintenance, or short-term works |
| Debris and sediment entering pits or pipework | Stormwater Screens & Baskets | Passive interception in existing stormwater pits |
| Ongoing sediment build-up in drainage infrastructure | Stormwater Pits | Permanent installations in new builds or infrastructure upgrades |
| Turbid water during excavation or construction | De-Watering Bags | Temporary filtration of pumped or discharged water |
When Is Stormwater Treatment Required?
Stormwater treatment is typically required whenever site activities create a risk of pollutants entering the stormwater network or surrounding waterways.
Common triggers include:
- Construction or earthworks generating sediment-laden runoff
- Vehicle washdown activities on outdoor or unroofed hardstands
- Fuel, oil, or chemical exposure from plant, machinery, or vehicles
- Industrial or commercial operations connected to stormwater drainage
- Sites near sensitive waterways or environmentally regulated areas
In many cases, stormwater treatment forms part of a broader site management approach, combining containment, diversion, and treatment depending on the risk level and operating conditions.
The most effective solution depends on:
- The type of pollutant present
- Whether the risk is temporary or ongoing
- How water is generated (rainfall, washdown, or process runoff)
If you’re unsure which system is appropriate, it’s common to start with source control or diversion, then scale up to engineered treatment systems where required.
FAQs
What is stormwater treatment?
Stormwater treatment refers to systems and controls used to reduce pollutants such as sediment, oils, and debris before runoff enters stormwater networks or waterways.
What’s the difference between stormwater management and stormwater treatment?
Stormwater management focuses on controlling how water moves across a site, while stormwater treatment focuses on removing or isolating pollutants from that water. Most sites use a combination of both.
Do all sites need stormwater treatment systems?
Not all sites require the same level of treatment. Requirements depend on site activities, pollutant risk, proximity to waterways, and local authority expectations.
What’s the difference between diversion and treatment systems?
Diversion systems redirect contaminated water away from stormwater networks, while treatment systems actively remove pollutants before water is discharged or reused.
How do I know which stormwater treatment solution is right for my site?
The right solution depends on the type of runoff generated, pollutant risk, and whether the issue is temporary or ongoing. Reviewing the comparison table above is a good starting point before exploring individual product pages.
