The 9000 Litre Pelican Plot Attenuation System by Turtle Enviro is a fully sustainable, "all-in-one" packaged system designed specifically for managing surface water runoff for single houses and small development plots. Unlike traditional crate systems, the Pelican system utilizes a high-strength, 1200mm diameter attenuation tank paired with advanced silt management and flow control.
Delivered ready to install, this system offers a quicker, simpler, and more cost-effective alternative to modular crates, requiring no complex membrane wrapping or specialized geotextiles.

This package includes as standard:
Optional Out Flow Upgrade
Complete Packaged System: Includes a Siltblok 300 Silt Trap, a high-strength 1200mm diameter tank, and a Flow Control Chamber (Oriflo or Vortiflo).
Quicker & Cheaper Installation: Eliminates the need for geotextile wrapping or membranes. The system can often be installed using reclaimed material, providing significant site savings.
Superior Silt Management: Features the unique Siltblok system, designed to remove up to 99.9% of silt and total suspended solids (TSS) before they enter the attenuation tank.
Precision Flow Control: Choose between the Oriflo (orifice plate) or Vortiflo (vortex) chambers to meet specific discharge rate requirements set by local authorities.
Durable Construction: Manufactured from high-strength plastic, ensuring a long design life and resistance to ground pressure.
The Pelican system is engineered to solve the common headaches associated with traditional soakaway crates:
Reduced Labour: Because it is a pre-fabricated "tank" system, there is no assembly of individual crates or on-site welding of membranes.
Silt Protection: Traditional crates often fail over time due to silt build-up. The Pelican’s integrated Siltblok trap ensures the storage volume remains clear and functional for decades.
Site Versatility: The high-strength 1200mm diameter tank is robust and reliable in various ground conditions, providing a predictable and easy-to-inspect solution for building control.
