TrashTrap
Capture Floatables With Innovative Netting Systems
Trash Removal Solutions for Stormwater, Urban Runoff and Combined Sewer Overflow (CSO) Discharges
TrashTrap™
Trash Removal Solution
TrashTrap netting systems combine the natural energy of water flow with disposable mesh nets to capture and easily remove trash, floatables and solids from stormwater and wastewater. The systems can be adapted to a variety of applications; several net size combinations are available.
Advantages
Proven Performance
- 97% removal efficiencies recorded by U.S. EPA-sponsored projects
- Certified by Los Angeles Regional Water Quality Control Board (LARWQCB) for full capture with 5-mm nets
- 25 years of experience in manufacturing, installing and maintaining netting systems
Trusted Technology
- Three-dimensional netting technology removes floatables, trash and debris while providing a larger surface area than traditional two-dimensional screens
- Less maintenance is required because nets can accommodate a larger volume of material, and do not need mechanical devices to remove blockages
Efficient Design
- Engineered to meet site-specific requirements, can accommodate any flow
- Utilizes the passive energy of water flow to drive pollutants into nets, no electricity needed
- Hydraulic relief prevents flooding while containing trash and debris, even when the event exceeds the design flow
- Negligible headloss, as system does not rely on head pressure to function
- Modules can be easily retrofit into almost any stormwater system
Environmental Solution
- Trash and debris are contained and drained dry, reducing further decay and leaching into water
- Efficient, cost-effective trash removal solution for TMDL and municipal requirements
- Quantifiable debris measurement easily attained for environmental permit requirements
Quick Installation
- Prefabricated, modular system enables quick installations
- Low capital and installation costs
- On-site supervision available on each project
Easy Maintenance
- Accessible for inspection and maintenance
- No confined space entry is required, as net change-out is done at the surface
- Long service life, with cost-effective maintenance
- Scales can be attached to lifting equipment for easy measurement of debris to meet environmental permit requirements
- Remote monitoring available through Telnet
Standard Configurations
In-Line Module
The in-line module is completely hidden from view, installed underground and upstream of the outfall. Components are installed in a high-strength precast concrete chamber, and servicing is easy due to ground-level access. In-line modules are installed in very tight locations and easily retrofit into almost any stormwater system.
End-of-Pipe Module
End-of-pipe modules are utilized where the end of the collection system enters the water course. They easily retrofit to existing outfall structures, and the robust design can handle very large storm events.
Floating Module
Floating modules perform in the same manner as end-of-pipe systems, but they float on the water. The pontoon structure floats constantly at water level, and funnel and side curtains direct trash into nylon nets. Floating modules can accommodate high storm events, and the prefabricated structure makes for fast installation.
