Stormwater Treatment Products & Systems
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
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
- Locally manufactured 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
- Australian-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 works are complete
First Flush Diversion Systems
Automated systems designed to divert the initial, most contaminated runoff during rainfall events before clean stormwater is allowed to discharge.
- Captures the first flush of rainfall where pollutants accumulate between rain events
- Suited to large wash areas and hardstands that cannot be manually cleaned
- Programmable diversion volumes to suit site conditions and rainfall events
- Operates automatically without manual intervention
Oil Water Separators
Engineered treatment systems designed to separate oils and hydrocarbons from contaminated stormwater before discharge or reuse.
- Treats oily or hydrocarbon-contaminated runoff from industrial sites
- Used where higher levels of treatment are required prior to discharge
- Suitable for permanent installations and engineered stormwater systems
- Typically specified for sites with vehicle activity or fuel exposure
Automated Wash Down Diversion Systems
Automated diversion systems designed to redirect contaminated washdown water away from the stormwater network during wash activities.
- Diverts washdown water to trade waste or holding tanks when taps are in use
- Operates automatically during washdown and returns to stormwater during rainfall
- Suited to outdoor and unroofed wash bays and hardstand areas
- Commonly used for vehicle, equipment, and machinery washing applications
Spill Control Systems
Automated monitoring and diversion systems designed to detect contaminated runoff and prevent polluted stormwater from being discharged.
- Continuously monitors stormwater for hydrocarbons or contaminants
- Automatically diverts polluted runoff away from the stormwater network
- Operates 24/7 during rainfall events without manual intervention
- Typically specified for high-risk or sensitive sites
All systems are Australian-made, tested for tough site conditions, and backed by expert advice.

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?
IDiversion 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.
