Firth's EcoPave System is a complete paving system that will help maintain the natural water balance as part of a property development.
Traditionally, land development has had a negative impact on the natural flow of rain, stormwater and nutrients. Runoff from impermeable surfaces not only increases demand on drainage systems during rain, but also starves adjacent vegetation and subsoil of water and nutrients and increases the rate of erosion.
Benefits:
•Reduces rainfall runoff from hard surfaces, decreasing the demand on drainage systems.
•Reduces the need for retention structures (e.g. ground sumps, ponds or dams) and maximises land use by retaining water within the Permeable Paving System.
•Recharges natural groundwater and aquifers.
•Improves hydrological response of stormwater peak flow by holding and releasing in a controlled manner.
Filters run off water by removing heavy metals such as zinc and copper through cationic exchange when using greywacke sub base drainage aggregates.
