Installation and User guide – ECOROCK 700 to 900 Units – 05-12-2016
The Primary Tank must be equipped with an efficient Effluent Filter
Use of the integrated Pump Well
If the effluent can’t be discharged by gravity, the integrated pumping well should be equipped
with a pump. The pump is required to lift the effluent (purified water) to a higher level.
Alternatively and if necessary an external pump well & pump can be installed after the system.
The seals on the BIOROCK tanks are flexible and have a diameter of 110 mm
The discharge pipe for the treated effluent should have a minimum gradient of 1%
4.1.3 Installation of the ECOROCK treatment unit
The ECOROCK unit must be installed downstream of the Primary Tank
The effluent from the Primary Tank should flow by gravity to the ECOROCK unit
The gradient of the treated effluent pipe to the ECOROCK unit should be a minimum of 1%
4.2 INSTALLATION IN DRY GROUND CONDITIONS
See Appendix
«Installation in dry ground conditions»
Conditions for installation:
-
Dry and stable ground conditions
-
Absence of water at the bottom of the excavation
4.2.1 Installation and digging in dry ground conditions
The maximum level of top soil above the backfill is 200 mm
The units must stand on a clean and stable base such as concrete
In dry ground conditions pea gravel can be used
Mud and other soft materials must be removed from the bottom of the excavation prior to
installation
A stable base must be created at the bottom of the excavation
The base of the excavation should be level and compacted
There must be a distance of at least 300 mm between the walls of the excavation and the
units
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
