1GENERAL
1.1 Design parameters
These instructions contain a description of the operation, installation and maintenance
of the EuroHEK sand and sludge trap. EuroHEK functions in many systems as a part of
a larger separator complex preceding an oil separator unit. See separate instructions for
the operation, installation and maintenance of the SandSET 101 sludge alarm, which is
included as a standard in EuroHEK sand and sludge traps.
An optional extra for the SandSET 101 is the Labcom Data Transferring Unit, which
enables the alarm signal to be automatically forwarded to the person or company
responsible for emptying the sand and sludge trap.
1.2 Important when handling and installing the sand and sludge trap
•The sand and sludge trap must be handled with care and it must be fastened
properly for the transport.
•Immediately after the transport, at the installation site, the sand and sludge trap
must be inspected for any damage that might have occurred during the transport.
•The maximum installation depth of the EuroHEK sand and sludge trap, from
ground level to the lower edge of the input sewer, is 2.5 metres. If installed
deeper, the sand and sludge trap should be ordered in a reinforced construction.
In this case, please contact Wavin-Labko / Tanks.
•Anchor the sand and sludge trap to prevent it from floating; this is the buoyancy-
effect caused by the groundwater or the rainwater that pours into the excavation.
See further information in “Instructions for Mounting in the Ground”.
•In the area of heavy and medium weight traffic a traffic compensating slab must
be laid on the sand and sludge trap to equalize the wheel loads. See further
information in “Instructions for Mounting in the Ground”.
2TECHNICAL DATA
2.1 Operation
In the sand and sludge trap EuroHEK the solid matter is separated from the waste water.
The operation of the sand and sludge trap is based upon gravitation, and the solid
particles, heavier than water, settle at the bottom of the tank. The tank is desludged by a
suction hose of acontainer truck through a maintenance shaft.

2.3 Accessories
2.3.1. Anchoring belts
The tank should be anchored by means of non-stretching polyester belts. The nominal
capacity of the belt is determined by the tank size and the type of ratchets by the
surrounding ground. You will need as many anchoring belts as the sand and sludge trap
is long in metres. In demanding conditions, the security can be enhanced by increasing
the amount of belts. Instructions for belt dimensioning can be found e.g. on the Wavin-
Labko web pages www.wavin-labko.fi.
In easy corrosion environments (calcareous or sandy soil, gravel, loamy sand, soil layers
above ground water surface which pass air well or relatively well), electroplated zinc
coated ratchets can be used to tighten the belts.
In highly corrosive environments (clayey soil, humus, peat, slag, mud, sulphides,
ground water level fluctuation zones as well as coast areas), stainless ratchets are
recommended.
Tanks of diameter 1 m are anchored by tying the belts tightly onto the lugs on the slab.
The nominal capacity of each belt should in this case be at least 2000 kg. Tanks the
diameter of which exceeds 1 m should always be anchored with belts that are tightened
by means of ratchets. In this case, also the nominal capacity of the belt should be
higher:
-tank diameter 1,4...2,2 m, easy corrosion environments; nominal capacity 4000 kg,
electroplated zinc coated ratchets and hooks,
-tank diameter 1,4...2,2 m, highly corrosive environments; nominal capacity 2500 kg,
stainless ratchets and hooks,
-tank diameter 3,0 m; nominal capacity 4000 kg, stainless ratchets and hooks.
The anchoring belts are available as accessories at Wavin-Labko.
2.3.2. Maintenance shaft
The maintenance shafts EuroHUK 600 and LM-HUK and the cast iron cover and frame
5…40 t are available as accessories for the sand and sludge trap EuroHEK. The gaskets
enable a watertight installation of the maintenance shafts. The type of the maintenance
shaft is selected according to the installation depth of the sand and sludge trap, as
presented in the following table:
Table 1. Determining the EuroHUK and LM-HUK maintenance shaft
Type of the maintenance shaft 9-13 13-17 17-21 21-25
From inlet sewer to ground surface (mm) 900-1300 1300-1700 1700-2100 2100-2500
2.3.3. Cast iron cover and frame
The cast iron cover and frame of the maintenance or sampling shaft are chosen
according to the traffic load above the separator system (5, 25 or 40 t).
2.3.4. SandSET 101 sludge alarm
SandSET 101 is available as an accessory for the sand and sludge traps EuroHEK 600-
8000. SandSET 101 is an ultrasonic sludge alarm device, which signals when the sludge

EuroHEK Sand and Sludge Trap 16AI01ae
WAVIN-LABKO LTD7
layer on the bottom of tank requires emptying. The probe detecting the sludge is
installed at the preferable height, according to the preferred alarming level.
2.3.5. Data transferring unit Labcom
The Labcom data transferring unit can be attached to a SET alarm system, e.g. to the
SandSET 101 sludge alarm. The data transferring unit Labcom enables the alarm
indicating the need to empty the sludge storage space to be automatically forwarded to
the person or company responsible for the task.
By using a user name and a password, the customers can read the data concerning their
property on the Internet. The data can also be transferred as an SMS to a GSM phone or
as an e-mail to a computer. The modem and phone line need not be kept open at the end
being monitored.
3INSTRUCTIONS FOR MOUNTING IN THE GROUND
These mounting instructions apply to the installation of the EuroHEK sand and sludge
trap.
3.1 Mounting pit and anchoring slab
1. Excavate a soil area of sufficient size for the sand and sludge trap. The edges of the
mounting pit should be estimated with 0.5 metres of extra space from both the sides
and ends of the sand and sludge trap. This reserves the space for the stone free
installation sand around the sand and sludge trap.
2. Compact a 30 cmlevelled stone free sand layer on the bottom of the pit.
3. If necessary, cast an anchoring slab or slabs on the sand layer, inserting a necessary
amount of RST lugs of min. diameter ∅10 mm to anchor the sand and sludge trap.
We recommend that an undivided anchoring slab is cast for the whole separator
system. If several slabs are to be cast, one must make sure that the slabs will not
move as regards to one another, and that the seams between the slabs will not be
under the tanks.
The tanks should be anchored in order for the buoyant force of the water in the
ground not to move the tank. A reinforced concrete slab is recommended to be used
as an anchor (figure 3).
An anchoring slab should be cast, if
othe ground water level in the area is higher than the bottomof the tank;
othe water transmission in the ground is weak and the rain water may gather
into the mounting pit of the sand and sludge trap; or
othe bearing capacity of the ground is weak.
Determine the positions of the RST lugs on basis of tank length and the amount and
placement of the anchoring belts before casting the concrete slab. Note! The
positions of the anchoring belts on the tank have not been determined by the
manufacturer. The belts are positioned on the straight part of the tank at even
intervals (ca. 0.8...1 m, at maintenance shafts ca. 1.5 m). Make sure that the belts at
both ends cannot slip off the tank.
Note! The anchoring belts should not be placed over the inlet and outlet sewers!

3.2 Installing the sand and sludge trap
1. Compact a min. 20 cm stone free sand layer on the anchoring slab.
2. Set the sand and sludge trap on the layer of sand and pour about 20 cm of water into
the tank to stabilize it.
3. Fix the sand and sludge trap onto the slab by means of non-stretching anchoring
belts. You will need at least as many anchoring belts as the tank is long in metres.
If the amount of anchoring belts is insufficient or the belts are not tight enough, the
buoyant force of the water in the soil can lift the sand and sludge trap up to surface
later on, when the tank is being emptied.
Fix the anchoring belts round the tank and to the RST lugs on both sides of the
anchoring slab (see figure 3). The belts should preferably be tensioned with
appropriate ratchets. If you order the anchoring belts with the tank, you will receive
the necessary ratchets with the belts. Other appliances are not allowed to be used to
tension the belts, because the belts might get overtensioned, causing damage to the
tank.
The recommended way to tension the belts is two-phase: each belt is first tensioned
to a level, where the force of the ratchet starts to increase substantially. In the
second phase, each belt should be tensioned again, starting from the first belt. Make
sure that the ratchets do not press onto the tank surface.

4. Compact the sand layer around the sand and sludge trap with extreme care. Keep
compacting the sand bed around the sand and sludge trap in 20 cm layers. While
this work is being done, keep adding water to the tank to keep it steady.
5. If the system is to be equipped with a EuroNOK sampling shaft including a shut-off
valve, see separate installation instructions for the sampling and shut-off valve shaft
EuroNOK as well as the instructions laminated onto the side of the shaft.
6. Install the inlets and outlets of the sand and sludge trap.
7. Install rubber gaskets onto the bottom edge of the maintenance shaft(s). Install the
EuroHUK maintenance shaft in a vertical position into the installation frame of the
sand and sludge trap. Lock the retaining latches (see figure 5).
If required, attach the RP-maintenance shafts (LM-HUKs) into their installation
frames. Do not let the gaskets slip off their grooves. Certain lubricants contribute to
an easier installation of the RP-maintenance shafts.
8. Install the ventilation tubes onto the ventilation outlets on the maintenance shafts.
9. Install the sludge alarm probe of the SandSET 101 into the sand and sludge trap
(comes as a standard in models 10000-50000, an accessory in other models). The
connection box is hung on the metal hook on the upper edge of the maintenance
shaft. After this, determining the preferred height of the probe is possible;
recommendation is 1/3 of the tank volume.For further information, see figure 4.

10. Install the cable protection tube into the cable penetration at the top of the
maintenance shaft. The probe cable should be pulled into the building through the
cable protection tube. Leave enough cable inside the maintenance shaft to lift the
probe on the ground surface for maintenance operations.

11. Continue compacting the sand in 40 cm layers until the ground level is reached.
Avoid the use of heavy vibration when compacting sand layers on top of the tanks
or their inlets and outlets.
12. After filling the pit, cut the maintenance shaft in a proper height. Note that the cover
and frame will give about 100 mm extra height for the maintenance shaft.
13. After cutting the maintenance shafts in a proper height, the frame of the cover and
frame assembly is installed on the maintenance shaft. The frame must not lean
against the maintenance shaft, but against the surrounding compacted layers of sand
or a load compensation plate and the asphalt layer laid on the ground surface.
14. In an area of heavy and medium weight traffic, a load compensation plate and a
layer of asphalt must be laid to equalize the wheel loads. See figure 5, and the
instructions on the body of the sand and sludge trap concerning mounting in the
ground.

15. Finally, fill the tank completely with water to ensure its effective operation. Filling
with water will also diminish the effect of the groundwater buoyancy.

4MAINTENANCE
1. Check the condition of the sand and sludge trap at least every six months. Also
measure the thickness of the sludge bed regularly.
2. Sludge can be removed from the bottom of the tank by a container truck. It should
be removed when one third of the total volume of the sand and sludge trap has been
reached, or at least once a year.
3. The EuroHEK sand and sludge trap should be completely emptied at least every
second year. When doing this, clean the dirt from the walls with tap water or by
high pressure washing. Check also the condition of the sand and sludge trap.Right
after finishing the service, fill the tank completely with water to ensure the new
starting up of the cleaning process. In areas of high ground water level, the filling
with water reduces the buoyancy effect, too.
4. The probe of the SandSET 101 must always be cleaned and checked when
desludging the tank and in connection with the annual maintenance procedures.
Cleaning can be done by using a mild detergent (e.g. dish washing liquid) and a
brush.
