What Is Aquaflow® Permeable Paving System? Formpave's® Aquaflow® permeable paving system is a sustainable urban drainage system (SUDS). The Aqualflow® system prevents run-off and flooding from paved areas, and collects and filters storm water for later use.
The patented system allows rain to infiltrate through a permeable block paving surface into a unique sub-base. How does it work? The water passing through the Aquaflow® SUDS system is cleaned by filtration and microbial action. It is then released in a controlled manner into sewers or water courses. Or, can be harvested and used for watering plants or flushing toilets.
