A septic tank made of concrete rings is a practical solution to the problem of drainage and recycling of sewage in private houses that do not have a connection to central communications.
Its use has become widespread in the arrangement of autonomous treatment facilities for country cottages and summer cottages.
An overflow concrete septic tank is a tank consisting of one, two or three chambers-compartments. The number of sections depends on the estimated volume of wastewater and the intensity of discharge, therefore it is calculated for each project individually.
For a country house with a large number of residents, a three-chamber septic tank is suitable, in which the first two tanks are hermetically sealed, and the latter is equipped with a crushed stone bottom filter and serves to drain drains into the ground.
The optimal variant is a well consisting of three rings with a diameter of one meter.
A single-chamber septic tank is a storage tank in which purification and water drainage are not performed. Contaminated liquid from such structures is pumped out independently using drainage pumping equipment.
The popularity of concrete septic tanks and a large number of positive reviews are due to a number of indisputable advantages of these structures:
The weight of the rings assumes the use of construction equipment during their transportation and laying, which is also referred to as a disadvantage of the structure. In addition, single-chamber tanks require regular pumping of sewage, and multi-chamber tanks require periodic cleaning of the sump.
Many users also note that in case of untimely maintenance of the septic tank, an unpleasant odor may spread.
