What capacity to take under the sewer

To collect the waste in the system of domestic sewage, as is well known, special storage tanks are used, which perform the function of a septic tank and are periodically emptied with the help of waste disposal equipment. In its most general form, such a tank is a volume tank with two holes, one of which serves to connect the sewer supply pipe, and the other is the technical hatch used for cleaning.

Before you decide on what capacity to take under the sewage system you should familiarize yourself with the well-known variants of its execution, which are widely used in practice. These options include:

  • plastic drums;
  • metal containers;
  • concrete drives.

Consider each of these performances in more detail.

Plastic tanks

Plastic storage tanks

Among all the types of containers listed above, plastic barrels are the most popular, featuring the following advantages:

  • lightness of the material, significantly simplifying the installation of the tank;
  • high tightness due to lack of welds;
  • enviable durability due to non-susceptibility of the material to corrosion and the damaging effects of aggressive media;
  • relatively low cost.

Due to the chemical neutrality of plastic materials, such containers can be used for up to 35–50 years. In addition, choose a suitable plastic vessel with a capacity of about 3? 4 m3 these days are not particularly difficult. In addition, plastic products are characterized by high mechanical strength, comparable to the performance of metal containers.

For objectivity, the characteristic disadvantage of this choice should be noted, which consists in the fact that, due to its lightness, bulk barrels can be pushed out of the soil under the influence of groundwater or heaving of the soil itself. That is why when installing a plastic storage device, additional measures are needed for its reliable fastening in the ground.

Metal containers

Metal capacity

At the next place in popularity with the user are metal containers, which are known to everyone, which are installed, as a rule, with the involvement of special equipment. For maximum protection of the tank material from corrosion, its internal and external surfaces are treated with a special anti-corrosion material, which allows extending the product's service life. Often, as a coating, special moisture-resistant dyes are used (enamel HV-785, for example).

In addition, before installing in a previously prepared place (to avoid the ingress of sewage into the soil), the connecting seams of the metal tank are carefully sealed.

Barrels 216,5 l

With regard to the specific choice of capacity of this type, due to the high cost of metal tanks of factory production for the arrangement of small drain holes, standard 200 × 250-liter barrels are most often used. Due to the limited volume of such barrels, the latter can be used only in temporary residence places (in summer garden plots, for example), where the volumes of domestic wastewater are usually small.

Tip! In addition to the high cost, the disadvantages of metallic containers, which significantly limit their use, should also include low corrosion resistance, which requires additional measures to protect their surfaces from rotting, as well as a limited amount of metal collectors.

Concrete tanks

Capacity of concrete rings

Concrete sewage collections are not uncommon. Although the installation of concrete rings can be fraught with some difficulties, but the safety margin is worth it. According to experts, such a cesspool can last 100 years.

Concrete septic tank

Thus, based on the results of consideration of existing options for the execution of containers for domestic sewage, we can conclude that because of the ease of installation and subsequent operation, many people opt for a plastic tank.

Making a competent decision on how to properly bury a container for a septic tank involves the fulfillment of certain conditions associated with the correct choice of place for it, as well as the need to comply with current sanitary standards. In this case, the following points should be taken into account:

  • the boundaries of the area allocated for the sump;
  • allowable distance to the nearest residential facility;
  • lack of nearby sources of drinking water.
