3. INTRODUCTION
o The purpose of privy digging is the salvage of antique
bottle and everyday household artefacts from the part.
o privy pit digging is a often conducted on private
residential properties.

a health hazard because animals and insects can
spread disease from the waste material back to human

4. Material needed for privy pit
 A privy pit is to take place, the map will show distance from
the pit to near by dwelling source of drinking water, property
lines and other.
 Showing the correct dimension of the pit.
 materials list describing all labour supplies and tools needed
for privy digging lining the pit the base of the pit.
 Also need a slab or cover to cover the pit immediately after
the base and lining are in place.

5. Locating map

6. When is a privy suitable
Privies are constructed where water under pressure
is not available or practical.
 The water table must be at least 1.6 to 2.1 mitres
below the surface of the ground in silty or clay soil
or 4 to 4.5 metres below the surface in sandy soil,
deeper in gravel

7. WHERE SHOULD PRIVY BE PLACED
20m from a lake, creek pond, river, etc.
20m from wells.
3m from properly boundary.
30m from own house/cottage.
15m from neighbours house/cottage.

8. HOW SHOULD A PRIVY BE CONSTRUCTED
 See attached plans.
 Excavate pit 1 to 1.5m deep crib sides to prevent
sloughing.
 Bottom of pit must be:-
 At least 60cm above water table in silty or clay soil.
 At least 3m above water table in sandy soil more in
gravel.
 Place privy structure so pit is not accessible or visible
from the exterior.

9.  Mound excavated earth so rain water and runoff do not
enter in the pit.
 Screen all opening in outhouse building and put self
closing device on the door to exclude insects.

10. Privy digging and construction
steps
Depending on local condition available of materials,
skills of workers and show on, some construction steps
will take only a few hours, while others may take a day
or more
Draw up a work plan that outlines required tasks and
rough time estimates based on local condition.
You will then have an idea of when specific workmen,
supplies and tools must be available during the
construction process.

11.  Determine the correct location of the pit, using the location
map similar to measuring tap.
 Clear the area of any vegitation that might hinder
construction.
 Lay out on the ground the correct dimension of the pit, as
shown in the technical drawing, and mark each corner of the
pit with a wooden stake or pointed stick as shown.
 Build the base around the pit site. This is done before digging
the pit to prevent the top of the pit walls from crumbling and
to ensure that the slab or cover can be put in place
immediately after the pit is dug and lined.
The following are construction steps for
building a pit

13. BASE OF PIT :-
Wood base
Brick base
Concrete base

17.  Privy pit digging can be dangerous.
 If the pit is deeper than about 1.5m the walls. Must be
shored during excavation to prevent a cave in that could
be fatal to a worker in the pit.
 Do not hand – dig a pit deeper than about 3.5m.
 Privy pit digging must take place at the exact site and to
the dimension specified by the project designer to
protect groundwater and other sources of drinking
water.
 A pit must be covered with a slab or a cover when it is
not attended and immediately after it is excavated and
the lining and base are in place.
