Internal vertical garden above the floor – sewage system
One of the types of indoor vertical gardens is the one built above the floor. This kind of green wall requires a different adaptation of the drainage compared to living walls built directly from the floor. This adaptation involves planning the drainage at the lowest point of the vertical garden being created. For example, if we want our garden to be suspended 100 centimeters above the floor, the drainage outlet is introduced at the same height – 100 centimeters. This is because at this height (the lowest part of the constructed garden), there is a collecting gutter. The water that gathers in it flows into the drainage outlet made at the same height.
The image on the left side presents an illustrative drawing of an indoor vertical garden suspended above the floor, along with the drainage. The drainage outlet, leveled with the wall, is concealed by a water collection gutter.
The drainage is commonly made from a pipe with a diameter of 32mm or 50mm. In most cases, however, we recommend using a 50mm diameter pipe.
Please note that the drainage pipe’s flange should be flush with the wall.
The drainage outlet should be placed as close to the center of the planned vertical garden wall as possible. If a situation arises where such placement is not possible, it can be moved to the left or right as needed. However, it is essential to remember that the drainage outlet must not extend beyond the outline of the green wall, nor come closer than 10 centimeters to either edge of the planned garden.
Please remember that it is essential to install a trap on the drainage outlet.
