GrasCell® RC550

Modular Stormwater Management Tanks
A high-strength modular system that can be configured as an underground stormwater tank, detention tank or retention tank for efficient stormwater management and flood mitigation in urban developments. Designed as a structural stormwater tank system, the RC550 modules form large underground stormwater storage tanks that temporarily store rainwater runoff before controlled discharge, reducing flooding and improving urban water management.

The system can be assembled into various stormwater tanks, including detention tanks, retention tanks, rainwater harvesting tanks and infiltration tanks, supporting sustainable drainage applications such as bioswales, biotopes, eco-ponds and urban stormwater management infrastructure. Engineered with exceptionally high compressive strength, the RC550 system is capable of supporting heavy vehicular loads, including fire engine access roads and emergency vehicle routes, making it suitable for installation beneath pavements, driveways, fire engine access lanes and landscaped areas.

With its robust structural design, GrasCell® RC550 stormwater tanks provide durable underground stormwater detention and retention tank solutions while maintaining fire engine accessibility and heavy load-bearing performance, ensuring reliable flood control and resilient urban infrastructure.
