StormTank® - Model Shield -Low-Cost Stormwater Pre-treatment Solutions
To complement our stormwater management products, our StormTank Shield offers a smart and simple solution for stormwater treatment. It reduces water pollution from the system by blocking both floatable and oil discharge from exiting the outlet pipe.
The StormTank Shield is a stormwater treatment device designed to reduce pollutant discharge through gross sediment removal and oil/water separation. It prevents floatables and oils that enter a structure from directly exiting the outlet pipe, ensuring they are unable to enter the management system and be conveyed back into the environment. This treatment solution reduces water pollution caused by runoff that would otherwise flow freely throughout our neighborhoods and environment.
By installing the StormTank Shield, these floatables and oils are blocked from discharging and polluting local waterways. Additionally, heavier sediments will settle in the sumped inlet, as the Shield increases flow length and reduces velocity of the runoff by maintaining a constant level of water in the structure.
- Reduces water pollution discharge
- Available for Water Quality Credit
Anti-Siphon Vent
Vortexes and siphoning are prevented by the built-in vent, which requires no additional parts or connections.
Access Port
The access port and slim profile simplify the cleaning process and ensure that nothing obstructs the discharge.
Hand Grip
The built-in hand grip makes the Shield easy to handle during the installation process.
Easy Installation
The Shield is conveniently available in 18-, 24-, and 30-inch sizes with pre-drilled mounting holes for easy fastening over the outlet pipe.
The StormTank Shield prevents floatables and oils entering a structure from directly exiting the outlet pipe. As stormwater runoff flows to the catch basin and enters the structure, it accumulates oil, debris, and sediment. These pollutants are often transported through the conveyance system and discharged into a storage system or directly into a stream.

Additionally, heavier sediments will settle in the sumped inlet, as the Shield increases flow length and reduces velocity of the runoff by maintaining a constant level of water in the structure.

StormTank offers support during the design, review, and construction project phases, which incorporate the Shield. StormTank Shields required no assembly and the pre-drilled mounting make for easy fastening over the outlet pipe.
