2.2.1 Planning
Issues to note when planning
•
A location is chosen taking
into account treatment plant
maintenance (i.e. not inside
recreational areas)
•
Location must not be inside a
pit gathering surface water
•
Determining electrical and
drain connections and pos-
sible need for pumping.
•
Treatment plant discharge and
overfl ow must be arranged so
that no backfl ow to the plant
can occur
•
The discharge and overfl ow
pipes are separately led into
the discharge location.
•
Freezing and ground frost
damage are prevented using
insulation if necessary.
•
Storm water and irrigation
water must not be drained
into the treatment plant.
•
The drain is ventilated to the
roof of the building.
•
If necessary, a discharge plug
is installed to prevent rodents
from entering the discharge
pipe.
•
Treated water discharge
location is chosen taking into
account the local conditions.
•
Discharge water may only be
soaked if the absorption capa-
bility of the soil is suffi
cient.
•
The absorption well or area
is measured based on the
amount of water absorbed
at one time, and a bypass
option is arranged in case of
clogging.
•
It is preferable to install an
inspection pipe in front of
the treatment plant. If the
discharge pipe is long, an
inspection pipe should also be
installed.
NOTE! Ensure discharge and over-
fl ow pipe functionality in winter
conditions
2.3 Installation
2.3.1 Before installation
•
Before installation, verify that
the tanks or treatment plant
equipment have not been
damaged during transport.
•
Remove the anchor package
from the sides of the plant.
•
Take out the parts and sup-
plies packed inside the plant.
2.3.2 Digging trench
•
Pay attention to work safety
when digging the trench, and
leave suffi
cient working room
around the treatment plant.
•
Level and mechanically
compress the bottom of the
trench using sand or gravel
(bedding level min. 150mm).
•
Ensure that the bottom of the
trench is level under the tank
•
Make subsurface drains in
trenches dug inside clay or
bedrock.
