Nowadays, more and more local authorities are requiring households to stop discharging rainwater into the sewer system. In such cases, draining rainwater into infiltration boxes is an ideal solution. 

Infiltration boxes act as a buffer for the rainwater you want to drain away in your garden, for example. The infiltration boxes are installed underground and wrapped in non-woven geotextile. During a rainstorm, they collect the rainwater and slowly release it into the surrounding soil over time. + read more + read more

Preparation: What do you need?

1. Infiltration boxes

Our crates have a capacity of 200 litres per crate. Allow approximately 1 crate per 8m² of disconnected roof surface. So for a roof of 80m², you would need approximately 10 crates.

2. Geotextile

Protects the crates from sand and soil without impeding their water permeability. Do not use ground cover fabric for this purpose.
3. Catch bassin leaffilter
Prevents your infiltration boxes from becoming clogged with sand and soil.

4. PVC pipes and bends
For draining rainwater to the crates. Quantity and length depend on your situation.

5. Gravel, sand or crushed stone
To fill and anchor the hole around the crates.

6. PVC glue and tape
PVC glue for attaching the pipes and tape for fixing the geotextile around the crates.

Additional requirements:

• Digging tools
• Spirit level
• Measuring tape
• Safety equipment (gloves, safety goggles)

Installing infiltration crates:
 

1. Choose the location
Find the spot where you want to place the crates. Make sure this location is at least 2 metres away from the foundation of your house to prevent moisture damage. Also avoid a spot close to trees, at least 2 metres away, to prevent damage from tree roots.
2. Dig the hole
Once you have chosen the location, dig the hole. First remove the paving if you are placing the crates under a patio. The hole must be deep enough for the height of the crates (approximately 40 centimetres) and have a minimum of 25 centimetres of cover (50 centimetres if the crates are under a car park/traffic load). Do not forget to leave space for the PVC pipes and the leaffilter.
3. Prepare the crates and place them
Put a layer of sand on the bottom of the dug hole. Then wrap the crates in geotextile, seal the seams with tape and place the crates in the hole.
4. Disconnect the downpipe

Disconnect the downpipe from the sewer. 
5. Place the leaffilter
Place the leaffilter between the downpipe and the infiltration boxes. Connect the sand trap to the downpipe using a PVC pipe and connect the other end to the nearest box.
6. Provide for rainwater overflow
Consider the possibility of heavy downpours and overflow from the infiltration boxes. Use the leaf trap as an overflow option or install an overflow at the crate furthest from the downpipe. This could be a drainage hose that you connect to the stop/outlet of the crate and lead to a lower part of the garden.
7. Fill the hole and cover it
Fill the hole around the crates with sand, gravel or crushed stone. Cover the system with at least 25 centimetres of soil or sand. Restore the patio, replant your garden (avoid trees with deep roots) and design the garden as desired.

Growing municipal requirements

Nowadays, more and more municipalities are requiring households to stop discharging rainwater into the sewer system. Draining rainwater via infiltration boxes offers an ideal solution to this problem. Allowing rainwater to infiltrate the ground reduces flooding and sewer overload. This approach not only helps to protect the environment, but also contributes to maintaining the groundwater level and prevents problems such as flooding in your garden.

How infiltration crates work

Infiltration crates act as a buffer for the rainwater you want to drain, for example in your garden. They are placed underground and wrapped in a non-woven geotextile, which allows water to pass through but protects the crates from sand and soil ingress. During a rainstorm, the crates collect the water and gradually release it into the surrounding soil. This ensures that rainwater is drained efficiently and prevents puddles and flooding on your property.

Frequently asked questions:

How deep should an infiltration crate be placed?
The depth of the placement depends on the height of the crates and the covering required. In general, the hole in which the crates are placed should be deep enough to accommodate the height of the crates, usually about 40 centimetres, with an additional 25 to 50 centimetres for the covering, depending on the type of use (such as under a car park).

How many infiltration crates do you need per square metre of roof?
A guideline is to calculate 20 litres of crate volume per square metre of disconnected roof surface. This means that, depending on the amount of rainwater you want to collect and the size of your roof, you should choose a number of crates that match the capacity you need.

Can infiltration crates become clogged?
Yes, infiltration crates can become clogged with sand, soil or leaves if a proper sand trap is not installed. It is therefore important to use a sand trap to prevent these materials from entering the crates and reducing water permeability. Regular maintenance and inspection are also recommended to prevent blockages and ensure the system works properly.
