Plastic Cesspools - Plastic Drain Pit

Today, construction markets offer many options for devices used in plumbing. Among these systems, plastic sumps are popular. What are these constructions? Consider their advantages and disadvantages, as well as the method of installation.

Benefits

Storage tanks for waste

Plastic containers are quite popular, since they have a number of advantages, among which are the following:

1. Along with low cost, the characteristics of these products are almost as good as reinforced concrete structures. In this case, the price of a single plastic sump will be lower than that of concrete rings. This option will undoubtedly be appreciated by families of two or three people who cannot afford expensive plumbing systems.
2. At manufacturing of holes modern technologies and materials are applied. Polypropylene, which is used as a raw material, has a low specific weight, easily resists corrosion, while possessing sufficient strength. Due to this, installation can be done without the use of heavy construction equipment with minimal use of manual labor.
3. Polypropylene is leakproof, which is much larger than that of concrete rings. At the same time, the plastic pit not only does not allow water to pass through, but also makes it impossible for unpleasant odors to come out, which, thanks to the special design, are retained inside.
4. The strength of such holes gives an invaluable opportunity to install products in any climatic zones, because these cesspools are not subject to deformation from critical temperatures or when they change.

Disadvantages

If the mold is squeezed with soil

Does it have cesspools from plastic any flaws? Yes, but in general they are not very serious:

1. The lightness of the structure forces the cesspools to be attached with chains or cables to the concrete slab laid on the bottom. This is due to the fact that over time, a product that is lightweight can be pushed out by loose soil or groundwater.
2. Random chance of damage from stones and other objects. This problem can be eliminated if you reinforce the walls of a plastic pit with fiberglass.

Instead of cables attached to a slab of concrete, you can use "anchors" - a special design that represents cables with weights that will not allow the pit to rise to the top.

Installation

They are not difficult to install

If the weight of the sump capacity of not more than 250 kg, a group of people consisting of about 5 workers will be able to easily carry out the entire process of mounting the product. What is the beginning of the installation?

First, it is necessary to determine the location on the summer cottage or the territory of a country house. Best of all, if the pit will be located close to the road, so that it is easier to pump it out with the help of a vacuum truck.

If you install the pit too far from the nearest porous scavenger entrance, you may encounter a number of problems. For example, in the nightman, the hose length to the pit may not be enough, and if it also leaks, then puddles of sewage may remain in the yard.

When we decided on the location, it is necessary to understand how deep the groundwater flows. After that, it is worth knowing the depth of soil freezing in the area where the sanitary system will be installed. This can be done by referring to the GOST tables or by asking those who have already carried out a successful laying of communications on the street.

By the size of the pit they dig a pit. You can dig it manually or using construction equipment. The second option is easier, easier and faster, but more expensive. When the foundation pit is ready, a base of concrete with a thickness of about 20 cm is made at its bottom, in which loops are made, so that cables are subsequently fastened to them. You can also lay a concrete slab on the bottom - however, in this case, the length and width of the pit may increase slightly. Concrete construction will not allow to land on the ground under a plastic pit.

The next step is to lower the tank. To do this, put it on the edge of the pit, tied with ropes and gently, slowly, lowered down and expose. The dimensions of the pit should be 55–60 cm larger than the pit.

The remaining space between the walls of the cesspool and the walls of the pit is covered with loose earth or sand. If water is not poured into the container before this process starts, the soil that is poured in can crush the product, and the cracks that appear will not be repaired. How much water should I pour? Its level should be higher than the top of the bedded soil by 20 cm.

At the end, rings are set, then finally level the surface of the soil around the plastic pit.

What else do you need to know

Pumping of a cesspool

If you observe during installation a few simple rules, we can guarantee the successful completion of work and high-quality work of the cesspool during its further operation.

So, setting the slab under the pit or pouring the concrete structure, you must adhere to the horizontal level. The distance between the walls of the pit and the plastic pit should be about 30 cm on all sides, at least 25 cm.

In addition to the aforementioned fiberglass, the walls can be reinforced with brickwork - in this case, a distance of 30 cm should be from the plastic container to the brick . A low-quality brick will be suitable for a masonry device; it is not necessary to plaster it - it will not allow the ground to crush the walls.

If ground water flows nearby, then instead of sand or soil, it is recommended to use a dry mix of cement and sand in a proportion of 1 * 4.

If the pit is deepened in the ground by 0.5 m and more, then it is necessary to think out for it a reinforced concrete floor. Also, do not forget about the ventilation of the pit.

Over time, it is necessary to remove accumulated domestic waste water, and all work must be carried out in a timely manner and periodically. To do this, it is necessary to call a vacuum truck once a month. And to remove the smell in the pit, you can add special bacteria that turn thick sludge into a liquid mixture to make it easier to pump.
