Installation and User guide – ECOROCK-5000 & BIOROCK Multirock Systems – 10-10-2017
*1
The caCapacity of the ECOROCK-5000 unit can be decreased or increased if the required
effluent
quality is of a higher or lower standard than the results achieved during the EN-12566-3
performance test
4.1.1 Before the installation of the complete system
Always keep the system accessible
Check the tanks and the associated equipment (internal reinforcements, connections, seals, etc.)
before installation, see technical details for each tank
A minimum distance of about 3 m
1
from the house and 3 m
1
from trees which have extensive
roots should be ensured
A minimum distance of 2.5 m
1
from any building should be ensured, otherwise the stability of
the building should be checked
The installation should be located away from any traffic areas and parking (at least 2 m
1
)
The installation of the BIOROCK system is possible in high ground water conditions if special
precautions are taken
Consult a professional engineer if the units are to be installed with extension sets
System lids should not be buried and should always remain accessible for maintenance
The minimum distance between the primary tank and the treatment unit is 300 mm
The distance between the side of the excavation and the tanks must be minimum of 300 mm
Connections for the BIOROCK system are made with flexible seals with a diameter of 110 mm
Local rules and legislation must be followed
4.1.2 Installation of the Primary Tank
The Primary Tank must be installed as close as possible (less than 10 m
1
) to the wastewater
discharge point of the property; this avoids fats clogging in the inlet pipe. With a longer pipe run
from the property to the primary tank the installation of a grease trap may be necessary
This 110 mm diameter pipe (100 mm minimum, 160 mm maximum) should have a minimum
gradient of 2 % and a maximum of 4%
The Primary Tank should always discharge by gravity into the (optional) Flow Management
System and ECOROCK Treatment Units
Install the Primary Tank allowing a gradient towards the BIOROCK system
The Primary Tank should be installed away from any traffic area, unless special precautions are in
place
The Primary Tank must be equipped with an efficient Effluent Filter
For installation at Commercial Sites such as Restaurants, Hotels, Pubs etc… particular
attention should be taken to FOG (Fats, Oil and Greases) management.
Excess of FOGs may affect the overall performance of the system and special
precautions for their removal may be necessary.
It is the installer’s responsibility to ensure that special precautions (i.e. properly-sized
Grease Trap or other extra devices) are in place to avoid FOGs affecting the BIOROCK
system.
