Concrete rings septic tanks

For many private homeowners of our country, the issue of sewage at first is very acute. One of the solutions to create an autonomous sewage system is a septic tank . Consider what it is and what are the advantages of this type of structure.

What is a septic tank?

A septic tank is a structure for cleaning wastewater by defending them and anaerobic sedimentation of precipitation. By themselves, they do not provide one hundred percent filtration of drains, so they need subsequent completion - with the help of a filter well, a drainage tunnel or any other similar structure.

Now the most popular option is plastic and septic tanks consisting of reinforced concrete rings. In this case, the height of the rings of the latter is 90 cm, and the inner diameter varies from 1 to 2 m.

Advantages and disadvantages of septic tanks from concrete rings

The popularity of the design of concrete rings can be called truly deserved. There are several reasons for this:

1. Concrete has high strength, so the design will be able to withstand the pressure that occurs as a result of soil abrasion due to frosts;

2. The use of concrete also guarantees a high service life - such that this does not even have to worry about it;

3. In addition, concrete septic tanks practically do not need maintenance: everything that is required from the homeowner is to pump out the silt with the fecal pump once a year, and rinse filters once every few years.

However, there are drawbacks:

1. Concrete septic tanks are almost omnivorous, but this “practically” has its own restrictions: in particular, it is not allowed to withdraw in them the waste of construction chemistry, as well as drains from water purification systems;

2. In the case when the installation of the structure can only be installed using an excavator or crane-manipulator, the cost of work increases significantly;

3. If “forcibly” divert water from the structure, then the structure begins to require energy and operation costs.

How and where to place a septic tank?

The normative acts, including numerous SanPins, prescribe quite specific placement requirements. Nevertheless, homeowners often depart from them, and in cottage and country villages their own, internal rules can exist, regulating the placement of treatment facilities. Despite this, several very specific recommendations can be distinguished by how and where to place it:

1. The structure should be located at a distance of at least 5 m from a residential building, while the filter well is customary to be located at least 8 meters from the house;

2. It needs to be placed so that, if necessary, the assignor equipment has access to it when it arrives at the site;

1. The distance from the fence to the structure should be at least 1 m, and if it is possible to increase it to 4 meters.
