5.3 Sludge removal

In the WehoPuts 5 and 10 
treatment plants, you can remove 
sludge by either using a sludge 
bag or using a vacuum truck. 
The sludge removal reminder 
can be enabled according to the 
instructions in section 4.3 when 
using a sludge bag. Selecting a 
vacuum truck sludge removal 
reminder comes automatically 
twice a year.

5.3.1 Sludge removal with 
sludge bag

During the cleaning process, 
residue sludge is pumped into a 
separate sludge bag that needs 
to be regularly emptied. In the 
WehoPuts 5 model, the bag needs 
to be emptied every 2 to 4 months, 
depending on family size and treat-
ment plant load. In the WehoPuts 
10 model, the replacement interval 
is on average 1 to 3 months. The 
sludge bag should be replaced 
when the surface of sludge in the 
bag reaches the halfway mark. If 
no sludge has accumulated in the 
sludge bag, see section 6.4.3.

The sludge basket has been 
attached to the brackets in the 
upper part of the storage tank. 

Sludge bag installation and 
replacement:

1. 

Open treatment plant lid and 
move the sludge pipe to the 
side before removing the 
sludge basket (picture 34).

2. 

Lift  up the entire sludge 
basket.

3. 

Release the string holding the 
mouth of the bag and lift  the 
sludge bag up together with 
the protective bag. You can 
compost the sludge bag with 
organic or garden waste.

4. 

Stretch the protective bag and 
install the sludge bag inside 
the protective bag. Bend the 
mouths of both bags over 
the edge of the basket and 
fi x with the ring. Ensure the 
bottoms of the bags reach 
the bottom of the basket 
(pictures 35 and 36).

5. 

Install the sludge basket back 
in the storage tank.

6. 

Insert the residue sludge pipe 
back in the bracket.

7. 

Lock the lid and wash hands.

NOTE! The bags are installed with 
the bottoms touching the bottom 
of the basket!

5.3.1.1 Sludge bag composting 

The recommended treatment 
method for the WehoPuts minia-
ture treatment plant sludge bag is 
composting. When complete, the 
compost is a good nutrient for e.g. 
growing fl owers. 

The best way to compost the sludge 
bag is to place it in a factory-built 
composter together with left over 
food or in a garden compost with 
plant residue.
