CivilsFlow™ Diffuser

CivilsFlow™ Diffuser:Optimised Rainwater Distribution for Soakaways & Attenuation Systems

The CivilsFlow™ Diffuser is a high-performance SUDS diffuser engineered for controlled rainwater distribution within attenuation tanks, soakaway systems, and infiltration units. Designed for Schedule 3 compliance and long-term durability, it reduces turbulence, improves infiltration efficiency, and promotes uniform stormwater dispersion throughout the system.

Offering comparable performance to Permavoid diffuser units, the CivilsFlow™ Diffuser provides a cost-effective solution for surface water management without compromising on strength or hydraulic efficiency. Built for contractors and designers seeking reliable Sustainable Drainage Systems (SUDS) components, it ensures consistent water flow and easy connection to existing pipework.

Manufactured from robust, high-strength materials, the unit is lightweight, quick to install, and rated for high load conditions (up to 715 kN/m²) — ideal for both residential and commercial drainage projects.
