How to make a sump - rules and tips for the construction of a septic tank

Septic tanks are needed to collect domestic wastewater, therefore, without these tanks, no building can function (except for warehouses and some industrial facilities). Periodically, they need cleaning, and with proper procedures, these operations will need to be carried out much less frequently.

Separator - a tank for collecting household waste. Subsequently, this liquid will be subjected to primary cleaning mechanically. Filtration of waste takes place in a natural way: solid residues settle to the bottom under the action of gravity and its own weight, while purified wastewater rises to the top.

When the tank is filled to a certain level, the surface liquid enters the next tank through a special channel. There she will undergo another purification step. The design of the septic tank is simple, so everyone can make it yourself.

Selecting material

The sump must be cleaned regularly and cannot be escaped. It is recommended to use for this purpose an aspenisation machine or to make everything yourself. Solid residues accumulate over time, and they will also have to be removed. Even if you use special products that are designed to dissolve them, cleaning can not be avoided. What and how to make a device to clean it less often?

Material is selected individually. To give preference to a certain name will help financial opportunities, the volume of waste, the ability to handle this or that material, preferences and the site itself. The main thing that is required from the septic tank, its tightness, as the wastewater is collected here in an uncleaned form and it is highly undesirable that they fall into the ground.

So, let's consider which materials to choose.

Plastic tanks

Plastic septic tank

Plastic tanks became the most common solution therefore, their cubic capacity varies in a fairly wide range. Such a capacity will last about 50 years. When installing it does not require additional sealing, which is an indisputable advantage. The disadvantage - requires weighting or anchoring, as it can rise.

Metal tanks

Tanks from ordinary metal will not be suitable for effective functioning, as they quickly rust and become useless. The ideal option is a railway tank, but a container made of any stainless material is also suitable.

Eurocubes

The septic tank of eurocubes

The Eurocube is a rectangular container. It is made of multilayer plastic, "clad" in a steel cage. Their direct purpose is the transportation of liquids and their long-term storage.

Since the material from which the Eurocube is made is light enough, installing it as a septic tank requires attaching the tank to the concrete base. To avoid the spread of unpleasant odors from such a septic tank, it is recommended to use drugs with bacteria.

Used containers are cheap, and if you go to nearby businesses, you can also find free ones. And all because of the need for the disposal of Eurocubs money, with which the owners of companies part reluctantly.

Concrete sump

Concrete construction

By and large, this is a deep hole with plastered walls and concrete floor. To make it, you will have to tinker a bit, making and installing formwork, choosing and laying reinforcement for reinforcement, pouring concrete. This process is long, because the concrete freezes for at least 30 days. At the slightest movement of the soil cracks appear in the structure.

Reinforced concrete rings

For the manufacture of a septic tank, reinforced concrete rings must be placed in a dug hole, having an even cylinder. For the tightness of this tank, the joints must be sealed with concrete. The disadvantages of this method of manufacturing a septic tank lie in the difficulty of lowering reinforced concrete rings. It will not be easy when making holes under the pipes.

Septic tanks of tires

Separator of tires

For this we will need used tires from big cars. The most difficult thing in this method is to ensure maximum tightness of the connections.

Installation of a septic tank

The process is simple:

• Choose the right place.
• Dig a hole with the required dimensions.
• We lower the selected container into the pit.
• We connect with the drainage well and conduct the pipes.
• Check for leaks.
• We do.

Specialists' advice

1. To avoid further disagreements with environmental services or neighbors, you should choose a place away from residential buildings . There are several unspoken rules that must be followed.The sump should not be closer than 20 meters from the well, 10 from water bodies and 5 from residential buildings.
2. If the septic tank is plastic, then it is necessary to pour sand under it, creating a pillow. On top of the sand cushion lies a concrete slab, to which the container will be fastened with cables. It is necessary to monitor the horizontal position of the tank being installed, which can be done with the water poured into it.
3. Made of concrete is reinforced without fail, for which reinforcement of 8 mm in section is taken.
4. The space formed between the pit and the selected reservoir should be gradually filled with sand. Sand should be regularly moistened with water, which will ensure its best shrinkage.
5. A septic tank on top can be covered with a concrete slab with holes for the hatch and ventilation. If you buy ready-made devices, then there are already hatches.

The manufacture of a settling tank is a necessary thing, but it is rather difficult and long to make it yourself, although cheap. If funds allow, then you can buy a plastic tank and then only earthworks and pipe installation will remain.
