SMART Stormwater Infiltration by GRAF.

So, what is stormwater infiltration?

Stormwater infiltration refers to the process where rainwater (stormwater) is absorbed into the ground. It is, at its core, a natural process that helps replenish groundwater supplies and reduce the risk of flooding.
In urban environments, many sealed, inorganic surfaces are introduced, preventing water from naturally being absorbed organically, as it is intended to. This puts heavy pressure on surface water systems like storm drains, rivers, or lakes and prevents water absorption to ground water, negatively affecting the natural environment.

Stormwater infiltration systems are designed to capture stormwater and control its release back into ground water sources without overwhelming stormwater infrastructure, preventing flooding and erosion of surfaces such as concrete or bitumen. 
 

EcoBloc SMART for stormwater infiltration.

In an infiltration application, inlet pipes connected to the tank transport stormwater from any sealed surface such as a roof or a car park, to inside of the tank where the stormwater is stored temporarily and slowly released in the ground depending on infiltration rate of the soil, restoring the natural cycle of water.

In an infiltration tank, after an excavation of the pit and compaction of the base, the installation team lay a geotextile layer and EcoBloc SMART base plates are assembled according to the design of the tank. Then, EcoBloc modules are clipped together to make sure every EcoBloc is secure, making the tank a strong structure, and end plates are connected to the lateral surfaces of the completed tank.

The final steps are to wrap the geotextile all around the tank, certifying overlapping on the geotextile, to avoid any material from outside entering the inside of the tank, and backfill the laterals with appropriate backfilling material.
