The drywell’s development over time

 

The drywell’s development over time


1st Generation – Stone drywell

Low percentage of hollow space
Large excavation
Risk of clogging
High installation costs (many stones, large hole and many man hours)
Complicated to connect
No cleaning effect

2nd Generation – Plastic crate

Large percentage of hollow space
Small excavation
Low risk of clogging
Lower installation costs
Requires connector sleeves and a precise connection
Requires a very even surface to stand on
 

3rd Generation – BIO-BLOK® rainwater drywell

Large percentage of hollow space
Smaller excavation
Low risk of clogging
Lower installation costs
Flexible connection – no connector sleeves
Does not require a completely even surface for standing on
Can be adjusted to the conditions (blocks can be divided in two)
Cleaning effect due to a large surface area in the blocks (the requirement of drywells for the future!) 


The drywell of the future must be both easy and flexible to work with and must be able to assist the cleaning of rainwater before it seeps into the ground. This is only possible when using BIO-BLOK® elements which have a large surface area per m3. Third generation drywells are a combination of a block for wastewater cleaning and a drywell. This combines the best of both worlds.
