DO NOT begin using the HomeBiogas toilet unless you have
completed system activation according the the HomeBiogas
User Manual.
The system cannot properly break down waste before activation
and this will make the system produce unpleasant smells.
CAUTION:

introduction
The HomeBiogas toilet is an add-on to the HomeBiogas domestic biogas
system that allows users to turn human waste into clean energy in the
form of cooking gas.
The HomeBiogas digester only provides primary and partial wastewater
treatment for the connected HomeBiogas toilet. While rich in nutrients,
euent from the system requires further treatment according to local
wastewater treatment regulations.
Fully o-grid-ready toilet
can use various water
sources for ushing
hand-pump ushing action uses
only 1.2l of water per ush
waste converted to clean cooking

option 3 (If option 1 and 2 not possible):
build a draineld/mulch basin
option 1 (preferred):
connect to existing sewage system
option 2:
connect to existing septic tank
2. planning a suitable euent management system & connecting
the euent output from the homebiogas digester

location planning
You can install the bio-toilet indoors as a replacement for a regular toilet, or construct
an outhouse for the toilet nearer to your biogas system.
To ensure a smooth installation process and a well-functioning bio-toilet after
installation, it is important to properly plan for the toilet’s location, mounting
surface, and plumbing connections to the system, as well as a suitable euent
management method.
It is important to plan the bio-toilet’s installation within the maximum distance of the
connecting piping (see next page).

up to 5m
There are 2 main ways to connect the bio-toilet to your HomeBiogas system - the option you
choose will aect where you can locate the bio-toilet (maximum distance from system).
Option 1 (Recommended):
The toilet’s discharge elbow must be at least 1m above the fertilizer outlet opening (where the
wastewater pipe enters the system)
In this type of installation, the toilet can be located up to 10m (33ft) from the HomeBiogas system.
Option 2 (where option 1 is not possible):
The toilet is on the same level as the system (discharge elbow of the toilet MUST NOT be lower than the
base of the system)
A second vented loop must be installed along the wastewater pipe, close to the bio-toilet. The rst
vented loop near the toilet must be LESS THAN 1.2m ABOVE the toilet discharge elbow, and positioned
HIGHER than the fertilizer outlet vented loop.
In this type of installation, the toilet can be located only up to 5m (16ft) from the HomeBiogas system.

installing the toilet
• Flexible, reinforced sanitation hose (38mm/1.5in) of suitable length to connect toilet to system.
An odor-proof sanitation hose is recommended, especially for indoors toilet connections.
• 8mm diameter bolts for mounting toilet bowl (length depending on ooring/platform)
• PVC pipes and ttings to connect fertilizer outlet to chosen euent system (length depending
on toilet location - p15)
• Optional ball valve for 38mm/1.5in pipe, to install after pipe for easier maintenance
If constructing draineld/mulch basin (optional - refer p16):
Draineld:
• large gravel (1-2”diameter), 180 - 360 liter
• ne gravel (0.25-0.75” diameter), 25 - 75 liter
Mulch Basin
• landscaping mulch, large wood chips, ne wood chips/sawdust
Other tools required:
• Power drill (holes for mounting toilet bowl)
• Screwdriver (at) for hose clamps
• Shovel for draineld construction

Mounting the toilet bowl and attaching the toilet seat
Parts & Tools:
1
The toilet is shorter than a regular home toilet. It must be bolted down securely onto the oor or on a raised platform.
If installing onto a platform, it should be level, rigid and strong enough to support the weight of an adult. Do not
mount the toilet on shipping pallets or other weak surfaces. The platform should measure at least 52x63cm (W x L).
• Toilet bowl & Pump assembly
• Toilet Seat and Cover assembly
• 4x 8mmø steel bolts (with matching nuts if mounting
on platform
• Plastic seat ttings (see picture)
• Power drill (holes for bolts)
• Pen/marker for marking drilling location
1. Place the toilet on the mounting surface and
mark the positions of the 4 bolt holes.
2. Drill out the marked holes and bolt the toilet
down to the surface with the appropriate bolts/
screws/fasteners for your chosen surface.
