Configuration of drywells

When installing a drywell, it is important that the vertical contact surface is as large as possible so that the best drainage can be achieved. The bottom of the drywell is not included in the calculation as it will often get silted over time.

The perfect rain water drywell is a drywell that can take the most possible water and which has the largest vertical contact surface possible. This can be achieved by installing long and narrow drywells, which in this way achieve the largest possible vertical contact surface to the soil. The BIO-BLOK® drywell is perfect here because you can divide it into the widths you want.


The BIO-BLOK® element can be divided easily using a saw.

In the following examples it is clearly shown that the longitudinal drywells have the largest vertical contact surface and, where it is possible to install longitudinal drywells these should be used in preference to square drywells.
