Septics

Size of cesspools for cottage houses

In order to find the right size of cesspool, it is necessary to turn to normative documents, for example SNiP 2.04.03-85.In it, you can find complete and correct calculations of the volume of the installation. For example:

• Wastewater, their consumption, does not outweigh 5 m3 / day.
• Wastewater has a flow rate of more than 5 m3 / day.

It should be noted that the average water consumption per person is 100-200 liters / day.

Types of plastic structures

As we know, in many markets, as well as in shopping centers, there is a large assortment of different types of polymeric sewerage facilities. At the moment, plastic septic tanks crowd out well-known concrete settling tanks, as new locations can be installed not only in suburban areas, but also in residential multi-storey buildings.

Septic tanks can be:

• Polyethylene.
• Polypropylene.
• Fiberglass plastic.

Characteristics of polyethylene structures

Polyethylene structures are very popular today, as they are made of reliable material and perfectly cope with their work under difficult working conditions. Such special facilities will not detain any waste.

Most often, these channels are produced by two-layer, three or four-layer, and thereby double their shelf life and make their walls twice as strong. Such cesspools have an excellent opportunity to be installed in different climatic zones.

Polypropylene and fiberglass settling tanks

Let's start by looking at polypropylene ducts. They have, like the pluses, and the minuses. If to compare with polyethylene settlers, polypropylene wins because of its stability. This channel can withstand very high temperatures heating the drain, about 140 degrees.

It also has good corrosion resistance and is most often used in industrial drains, as they have a very aggressive environment, and only a well-established, simple, clean-up construction with adequate technical characteristics can handle it.

If we consider fiberglass septic tanks, then we can say that they are made on a resin base with the addition of fiberglass, for the strength of the walls. This structure has a separate view of certain chambers, as well, it can and should be used in corrosive drains due to its corrosion resistance.

Basic mounting characteristics of

Installation of plastic sewer systems can be handled by small teams of 4-5 people. For starters, the sump should be tied to wooden boards, and when it is lowered, these boards are removed, and our structure descends on the string.

To install correctly, you need to follow these rules:

1. The moat should have sand, about 15-20 centimeters, properly leveled.
2. The walls of the trench and the walls of the settler should be at a distance of 30 centimeters.
3. The septum partitions must be covered with bricks so that deformation of the septic walls does not occur.
4. If the groundwater level rises above the sump pan, a cement-sand mixture should be used.
5. It is necessary to install reinforced concrete covers, if the septic tank is buried at a depth of 1.5 meters.
6. Upon termination of the sedimentation of the settler, it must be checked that everything is connected correctly.

Main incorrect process installation solutions:

1. Do not connect the septic tank to the concrete floor. The concrete slab helps to keep the settler in the necessary space.
2. When the sump is not dumped with sand or cement-sand mixtures, as they can help to prevent the sedimentation from the soil, due to winter deformation of the soil.
3. If the septic tank is only covered with sand, then on the ground, cracks may appear.
   

   It must be remembered that before the clarifier is sprinkled with sand, it is filled with water, so that splits, deformations and other cracks do not appear. It also helps to serve it for a longer time without problems.

4. The correct volume of the clarifier is not correct. The septic tank has two processes for purifying water, and the gutters are completely considered cleaned when all processes in septic tanks and filtration wells pass. For well-purified water, it is necessary to select wells with a large volume.
   

   It has always been assumed that the volume of the septic tank should be large, so that water enters the filtration well in a much cleaner way, and with this the cleaning will be needed much less. Especially, the settling tanks must be no less than the three-day size of the drainage.

5. Lack of ventilation or incorrect installation. To rid yourself of an unpleasant smell, there must necessarily be a fan riser installation with a septic pipe.
