4.2.2 Installation of the tanks in dry ground conditions

Once the base of the excavation is stable, the installation can begin

The Primary Tank should not be positioned horizontally; it must have a slight gradient
towards the water outlet

Before connecting any water or ventilation pipes, ensure that the units are perfectly
installed

Ensure that all levels are correct so that the wastewater can flow freely through the system

Check that all connections are correctly positioned

Ensure that the seals are watertight
4.2.3 Backfilling in dry ground conditions

Backfill the hole with 3 to 6 mm smooth pea gravel, or lean-mix concrete whilst filling the
tanks with water at the same level

Do not exceed 300 mm per filling and compaction cycle

Make sure that the BIOROCK® media is completely saturated with water

Do not backfill with the soil removed during the excavation: roots and stones can damage
the tank.

Do not compact the backfill material mechanically: compact manually.

Backfilling around and filling both the Primary Tank and BIOROCK® unit with water should
take place at the same time.

Once the backfilling is finished and compacted, check the levels of the tanks again

The lids or access covers of the system should be installed just above ground, level to
provide easy access for maintenance.

Close and secure all covers with screws

Complete the backfilling once all pipework has been checked and connected.
4.3 INSTALLATION IN HIGH GROUND WATER CONDITIONS
Appendix «Installation in high ground water conditions»
The ECOROCK units can be installed in high ground water conditions with special precautions.
If you don’t use a BIOROCK® Primary Tank, please confirm with the other manufacturer that
this Primary tank is suitable for high ground water conditions.
If you don’t use a BIOROCK® Primary Tank, please consult the manufacturer to
ensure this Primary Tank is suitable for high ground water conditions.
The level of the water table must never exceed the level of liquid inside the Primary
Tank. Extremely high water tables signify a flood risk which could cause water ingress
or collapsed tanks.
