Devices
In this appendix there are the technical data of all the devices used in the strategy.
In the strategy the totality of the devices represent a system of light infrastructure with
the triple function to support the human needs, activate the territorial regenerative pro-
cesses and create spaces of sociality in the settlement.
The system has the aims to mitigate the actual condition of the camp, and to prepare
the territory to the possible future scenarios after the camp.
There are three type of device:
- artificial
- hybrid
-vegetal
The entire system it has been thought to face a temporary situation, for this reason the
artificial devices are composed by removable materials that doesn’t affect directly the
soil. After the camp some of them could be removed, some could be converted.
The combined use of artificial technology and natural phytoremediation properties of
the plants to purify the soil, create a techno nature system.

For each device it is indicated the typology of void in which it could be placed and the
estimated duration in presence and efficiency.
For the vegetal elements, there are indications about their phytoremediation properties,
their growing and seasonality

Devices location and quantity
The amount of each device has been computed in relation with the number of the inhabitants and the avai-
lable space. The soil of the camp is completely covered with a light layer of drain gravel.
septic tank 1 each 1 hh about 5 person
rainwater harvesting and storage 1 each 5 hh about 25 person
phytopurification tank 1 each 5 hh about 25 person
micro garden 1 each 5-9 hh 25-45 person
evapotranspiration tank 1 each 2 hh about 10 person
rain garden In each part of the camp with an high risk of flooding
purifying trees Each large voids in the camp is filled for 2/3 with purifying trees
weed grasses Each 50 interstices there is 1m2 of weed grasses

Septic tank

Baffled Septic Tank (BST)
Description
This technology consists of septic tank followed by one or
more filter chambers. . The filter reduces the danger of clog-
ging of the soak away. Septic are in plastic material placed
close to the Cespit toilet under the ground.
Septic tank technology are placd between toilet and VFCW.
Technical use
Baffled Septic Tank (BST) is the most appropriate treatment
The BST are made by plastic material and they are going to be
system to treat the effluent of the Solids Free Sewers. When
removed during the Dismantellament Phase starting at 5 + x .
it is followed by a Vertical Flow Constructed Wetland, the ef-
fluent is fit for infiltration, reuse in agriculture or disposal in a
nearby stream. A BST is an improved septic tank because of
the series of baffles under which the wastewater is forced to
flow. The increased contact time with the active biomass (slud-
ge) results in improved treatment.
By providing a large surface area for the bacterial mass, there
is increased contact between the organic matter and the active
biomass that effectively degrades it. The Anaerobic Filter can
be operated upflow mode. The upflow mode is recommended
because there is less risk that the fixed biomass will be washed
out. The water level should cover the filter media by at least 30
cm to guarantee an even flow regime.
