How to choose the right septic tank for a summer residence with a high level of groundwater

Tags:Septic tanks

ABOUTThe absence of a sewerage system forces the owners of suburban dwellings to install autonomous treatment facilities. Their functioning depends on many parameters, including the proximity of groundwater flow. Their close occurrence complicates the creation of treatment complexes. In this case, suitable septic tanks for summer cottages with a high level of groundwater, which are adapted for such conditions.

Methods for determining the level of groundwater

It is possible to calculate the location of underground currents in the territory in the spring when the snow melts or after long rains in the fall.

Groundwater occurs in layers. Surface currents saturated with water not suitable for drinking

To independently find out the depth of underground arteries, you will need the following tools:

garden drill, the length of which is 2 m;
a spoon drill that can drill to a depth of 5 m;
a rod of a certain length.

In some cases, a test well is created to determine the distance to the water.

After drilling a well, it must be left for a day. During this time, water will appear in it. Then the water level is measured with a rod. Marks are made on it in advance that indicate centimeters. After that, for several days, the water level is monitored, if it does not change, then this is an indicator of the presence of water underground.

Underground currents can run in the most unexpected places

Some popular methods will help to determine this value. In this case, you need to study the vegetation in the surrounding area.

Certain crops may indicate proximity to moisture

Lingonberries, raspberries or blackberries grow well in areas where water flows no closer than 45-60 cm from the surface.Sea buckthorn, currants or gooseberries grow remarkably if the given groundwater level is 105-115 cm. If the water level is at a distance of 155 cm, then plum, cherry plum or cherry tree will feel great. Apricots, chestnuts and apple trees grow remarkably at a water table of 2.5 meters. Cranberries can grow in very wetlands.

Septic tanks for summer cottages with a high level of groundwater: varieties

The choice of septic tanks for a summer residence with a high level of groundwater depends on many factors.

Ground model of a septic tank

This model has a low cost. When installing this structure, you do not need to dig a pit and specially insulate it.

Surface equipment can be of various sizes

A ground septic tank is only a storage tank. When choosing such an installation, you should first choose a place for its placement. Such equipment will require a lot of space, and it is also necessary to regularly pump out the contents using special equipment.

The cleaning system on the surface can be massive and equipped with additional elements

Such septic tanks are suitable for summer cottages with a high level of groundwater, where they do not live all the time.

Useful advice! In the surface device, you can draw conclusions from the sink, washbasins and from the toilet bowl. Depending on the underground arteries, the container can be buried a certain distance.

Ground models may not always fit well with site design

Factory made septic tank

An important criterion for the selection of a treatment plant is tightness. Factory-made plastic containers fully satisfy such requests.

Factory-type structures are distinguished by great convenience and the presence of additional functions

Installation of such a structure is laborious. At the same time, a pit is dug out and all the necessary containers are placed in it.

Since groundwater can push the treatment structure upward, the septic tank must be well fixed. In this case, a concrete pillow is made, and then a container is attached to it.

Finished equipment is produced by many popular companies, for example, TRITON

Helpful information! For an area with a close passage of groundwater, equipment with three chambers is used. Primary cleaning will be carried out in the first tank, and additional treatment will be performed in the remaining two.

The nuances of installing septic tanks for a private house with your own hands

Septic tanks for summer cottages with a high level of groundwater are best installed in the autumn-summer period. For laying, you need to make a pit. In this case, it is necessary to accurately determine the height of the base and container. The structure should be secured with ropes. The trench must be made at a distance of six meters from the foundation.

In the presence of groundwater, it is necessary to fasten the septic tank with anchor straps.

With a high presence of groundwater, it fits drain pipe, and sand is poured to the bottom. A concrete slab must be installed on top.

Installation of functional structures is rarely done alone

Before filling the sand-cement composition, it is necessary to connect the structure with the filtration fields. In this case, special couplings are used to improve the tightness.

Useful advice! The cover of the treatment plant must be above the ground line. This will prevent melt and rainwater from getting inside. In winter, it is recommended to cover the cover with thermal insulation plates.

How to carry out a treatment plant when groundwater is near?

When placing groundwater near the surface, you can try to create septic tanks for a private house with your own hands. For their laying, brick or concrete rings are used.

Monolithic concrete wells are distinguished by their special performance, which function perfectly with the close passage of underground arteries

The work should take into account the following points:

there should be a space of 10-15 cm between the surface of the pit and the cleaning structure;
the thickness of the sand cushion is within 5-10 cm;
it is necessary to make formwork from boards;
so that the tank cannot move, you need to fill the distance between the surfaces of the septic tank and the pit with sand;
backfilling is done when the tank is gradually filled with water.

For a high-quality purification and filtration system, it is worth considering the installation of pipes and filtration fields

The simplest septic tank can be done by hand from plastic containers. You can use the Eurocube. In this case, the containers must be connected with special pipes through which the waste liquids will move. Finished chambers must be coated with special waterproofing.

Diy septic tank option from concrete rings: diagram and photo

You can create a solid septic tank from concrete rings with your own hands. The diagram shows all the main stages of installation.

Concrete plants can be carried out from several treatment tanks

Before moving on to installation, everything needs to be calculated and planned. In this case, it is worth determining where the structure of the tanks will be located. The following points are taken into account:

the length from the device to the building must be at least five meters;
the gap from wells to sources with drinking water is at least 50 m;
distance to reservoirs - about 11 m;
up to garden plantings about 4 meters.

It is worth considering the installation diagram of the simplest two-chamber installation

For laying concrete elements, the involvement of special equipment will be required. A crane and a truck may be needed. After the calculations, three holes are made, which should be 10-12% larger than the rings. The bottom of the first two trenches is equipped with concrete pads that are horizontally aligned. The bottom of the third groove should be deeper than the rest. Crushed stone and sand are poured into it.

Concrete ring structures cannot be assembled alone. These are dimensional septic tanks, which must be covered from above with special plates with a hatch

Rings are treated with a bituminous compound before installation. With the help of special equipment, concrete elements are placed inside. All joints are processed with liquid glass.

It is necessary to make holes for pipes, which, after installation, are carefully sealed

It is also worth digging trenches for connecting sewer lines. At the points of entry into the rings, sealing is performed using fittings and sealants.

After the sealed lubricants have hardened, sewer hatches are installed. Bituminous mastic is being processed. The wells are insulated with stone wool and expanded polystyrene.

The distance between the well and the soil is covered with earth. You can also use clay for better waterproofing. From above are performed blind areas made of concrete for the removal of sedimentary flows.

High-quality installation of the device will avoid the problem of high GWL

A septic tank is a necessary part of the sewerage system of a suburban home ownership. Its installation can be done on your own. In this case, it is worth following the installation work technology and following the instructions.
