What is an ecological cesspool? How to choose its size? How often do you empty them?
An ecological cesspool is commonly called a popular type of sewage treatment plant, i.e., a sewage treatment plant with drainage. They consist of a tank for the initial treatment of sewage (preliminary settler) and a system of drains, i.e., perforated lines, for their distribution in the ground within the plot. Sometimes the term ecological cesspool is also used to refer to sewage tanks without drainage. By adding the adjective ‘ecological, septic tank installation orlando fl ‘ producers want to emphasize that the septic tank is 100% tight, so the contaminants contained in it do not get into the ground in an uncontrolled manner, and thus do not pollute it. It is hard to look for such a slogan in industry terminology or regulations; it is rather a colloquial name, so let’s always find out what is behind it.
Ecological septic tank – construction
As we have already mentioned, the ecological cesspool consists of a preliminary settling tank and infiltration drainage.
The preliminary settling tank may have the shape of a horizontal cylinder or cuboid, with two hatches enabling access to its center. Most often, they are made of hard plastic (e.g., high-density polyethylene PEHD), septic tank installation orlando fl sometimes also of concrete. The sidewalls of the sidewalls and the bottom are to increase their strength during installation in the ground.
At the outlet from the tank, there are filter baskets, whose task is to stop larger impurities before getting into the draining drainage (so it must be cleaned regularly).
I am infiltrating drainage.
Pre-treated wastewater is directed to the system of perforated plastic pipes, whose task is to drain the wastewater into the ground slowly and evenly. The length and number of drainage lines are adjusted to the number of contaminants that are produced in the household and which will flow through them, as well as to the shape of the plot and the possibilities of their arrangement, as well as soil and water conditions. It must be remembered that vegetation with a deep root system cannot be planted above them; preferably, it is grass. For single-family homes, there are usually two or three drainage lines. They may or may not be the same length. At their end, aeration fireplaces are installed. Thanks to them, oxygen is supplied to the system, which promotes the wastewater treatment process.
The aeration fireplace ends with an exhaust vent, which must be led out about 0.5 meters above the surface. First of all, so that in winter, it is not completely covered with a thick layer of snow, thus preventing the flow of oxygen to the system.
