BRIEF INSTALLATION GUIDE
EUREKA ECOFOSA TANK
Step 1:
Identification of the type of soil (not applicable for hard or rocky soils).
◾Take a clod of soil and grind it into fi ne soil.
◾Place this material inside a glass or container with vertical
walls, measure the height that the soil reaches inside the
container (initial h) with the help of a ruler or tape measure (5
cm is enough).
◾Add water until the volume of light soil is completely covered
and let it stand for at least 1 hour to allow the material to
expand.
◾After this time, measure the fi nal height (fi nal h) reached by
the volume of fi ne soil.
◾Store tanks on a fl at surface free of objects that will damage the tank walls or fl oor.
◾Stock on no more than three levels in a horizontal position at ground level.
◾Avoid stacking tanks on mezzanine edges or places where they can fall and hit. Do not stack on more than two levels.
◾When handling, they should not be thrown from height, dragged or hit against walls or fl oors.
◾They should be lifted and transported by two people. Protect the connection plans and other components of the
system during handling and storage.
◾4” PVC reinforced pipe including elbow or tee.
◾Polyplas fi lter in polyethylene.
◾4” PVC exit pipe.
◾4” rubber pack ( long lip) for inlet and outlet.
◾4” rubber pack (short lip) for polyplas fi lter.
◾2” sludge extraction pipe (bag in assembly material).
◾Filter material
◾2” rubber packings for extraction tube
◾2” valve (not included)
Eureka introduces to the market its new line of polyethylene pit for wastewater treatment, with auto-cleaning
system, constituting one more solution that Eureka provides for the care of health and the environment.

and cover 10cm
Step 4 : Descent of Ecofosa
Step 5: Logging for extracted sludge
◾For the correct installation of your Ecofosa, the slope must be considered, until an angle is reached such that the
material remains stable, without collapsing inside the excavation.
◾To prevent the Ecofosa from collapsing, the Ecofosa should be fi lled with water.
◾For the cement base at the bottom of the excavation, it is recommended that it be made with a 1:5 cement-sand
mixture and electrowelded mesh. A minimum thickness of 10 cm is recommended to allow a fi rm and uniform
◾The Ecofosa can be assembled before lowering it into the excavation.
◾Place the rubber sealing gaskets (long lip facing out) and use silicone sealant (5).
◾From the inside of the Ecofosa to the outside, insert the Ø 4” (10 cm) PVC pipe with
the assembled elbow into the tank inlet (2).
◾At the tank outlet, also from inside to outside, mount the Ø 4” (10 cm) pipe.(4).
◾Place the POLYPLAS rising fi lter with its rubber seal and the tank outlet pipe as
indicated in the diagram. Soak the inside of the rubber seal (3).
◾The PVC fi lter material is placed inside the POLYPLAS fi lter. The fi lling material
should be kept inside the mesh bag. If it is necessary to clean this material. Do it
outside the Ecofosa and inside the mesh bag (8).
◾Place the rubber gaskets (long lip facing out) in the side and top holes, use silicone
to seal (5).
◾The sludge removal device can be assembled on the outside or inside (7).
◾Once the sludge extraction device is in place, it is recommended to place a plug in
the upper outlet pipe to prevent rainwater from entering or to prevent mosquitoes
from proliferating.
◾Place a 2” valve (not included) for the extraction of all (seal it with adhesive) from
the interior.
Lower the Ecofosa as shown in the fi gure, avoid hitting the walls of the Ecofosa.
Do not confuse the sludge drying bed with the well or absorption fi eld, which is where the effl uent water is

It is recommended that the Ecofosa be inspected at least every six months as this is the only way to determine when
maintenance or cleaning is required (a very thick layer or a leakage of fl oating material at the effl uent outlet will be an
indication of the need for more frequent removal of the effl uent).
