That is not a problem if
you use our heavy duty 2" Drainage Cell.
We will move water horizontally to the lower
point and pump it from there into a leach drain made out of our EcoRain modular tank system.
No street discharge at all.
Our 2" Drainage Cell is an structural void space Drainage Cell that is so strong that you can build the complete concrete slab base right on top of it.
TYPICAL DRAWING: This is the typical design drawing for the use of the EcoRain system as an underdrain, wall drain and leach drain using our modular tank system.
