EcoProtector

EcoProtector Applications:

  • Residential Subdivisions
  • Commercial and Industrial developments
  • Main Stormwater drainage systems
  • Retrofitting to existing Stormwater drainage systems
  • Stormwater harvesting projects
  • Combined sewer overflows
  • Any other applications where the target pollutants are primarily gross pollutants and oils and sediment

The EcoProtector is a hydrodynamic, full capture, high-capacity trash and debris removal GPT (Gross Pollutant Trap) with superior litter and organic debris capture. The EcoProtector has been designed to remove particles greater than 5mm using physical processes to trap solid waste such as litter and coarse sediment under low velocity conditions.
EcoProtectors are commonly used as the primary treatment for the removal of large, non-biodegradable pollutants in areas with a high fraction of impervious surfaces such as residential subdivisions, roads, car parks, industrial applications and any area that may require Stormwater treatment. Primary treatments include, physical screening, rapid sedimentation and separation processes. The typical retained contaminants include gross pollutants and coarse sediments.
Gross pollutant traps are most often used as part of a treatment process with other Stormwater treatment measures as they are not entirely effective in removing nutrient.

The Process
There are many different types of gross pollutant traps. All of them perform a similar function: Trapping litter and sediment above 5 millimeters in size so that they can be removed from the water system. By removing large pollutants, downstream treatment of Stormwater can occur more effectively.

The EcoProtector Process:
1. Capture of Gross Pollutants (Cigarette Butts, Cans and Bottles, Leaves, Tree Branches, Bags and other Litter)
2. Capture of Heavy Sediment (Clay, Dirt, Carbon Dust and Other heavy objects)
3. Capture of Hydrocarbons (Oils, Fuels Etc.)
The system will operate in both Low flow and High flow conditions (Start of a Rain event or a Full Rain Event)

High Flow Bypass
In the Full Flow event the extra water that the system cannot handle will by pass through the indirect screen direct to the outlet.
The System is designed with the By-Pass Screen at 60˚to flush clean in High flow conditions, preventing the block up of the Screen and to give a full aperture of the flow by pass duct, resulting in no reduction to flow

Oil Capture
The EcoProtector is designed with a closed By-Pass duct and the collection outlet riser tube has been placed midway on the side wall which allows high oil capture in Low Flow/First Flush situations. The EcoProtector capacity allows capture and retains oils and hydrocarbons with up to 20% of the system total capacity.

Engineering
All EcoProtectors have been individually engineered to handle the toughest environmental situations and proven in the toughest environments such as high water tables and volcanic soils. Problems in these areas have been solved with the installation of the EcoProtector.
The Packaged EcoProtectors are engineered to the following Standards:BS4994 – 1987, AS/NZS 1546.1:1998. Hydraulic and civil engineering can also be provided to your requirements.

Construction
Even though the EcoProtector is relatively light weight, pound for pound they are stronger than alternative stuctures. The EcoProtector has no joins leaving a smooth, clean internal surface that resists scum and sludge build up and allows no leakage to the external environment. The lightweight configuration of the EcoProtector simplifies handling and reduces costs in transport, labour and handling down time.

Installation
The EcoProtector is designed and built as one homogeneous unit to allow easy handling, transport and most importantly, installation: One of the most significant advantages of the EcoProtector over any other alternative Gross Pollutant Trap.
Ease of onsite installation and access, no heavy cranes and without the assembly of heavy concrete sections in the ground results in considerable cost savings: EcoProtector cuts down the labour and saves time and money!
A complete installation hand book is supplied to ensure the installation goes smoothly and to plan. The guide provides advice for lifting, OHS measures, handling techniques and other important requirements. Installation is typically:

1. Excavate hole
2. Place station in hole
3. Fill well with water about 20% of total volume
4. Back fill to locking ring
5. Pour ballast
6. Install all connections as per manual*
7. Back fill and pour top slab and install access cover*All installation requirements are as per installation data manual.
