Rating of the best septic tanks for high groundwater for 2022

The difficulties of arranging sewer flow in conditions of high soil moisture are known to owners of country houses and summer cottages in central Russia. After all, unsatisfactory functioning or lack of sewerage overshadows the time spent in a home without basic amenities. In addition, the high groundwater level (GWL) causes additional costs due to the need to install special equipment to ensure the full post-treatment of clarified waste liquids.

General information

A septic tank is an element of a sewerage system for the removal and storage of polluted domestic water and fecal waste.

The main task is the disinfection of waste and the removal of liquid after cleaning.

The use of sealed devices ensures safety for the environment and humans. The frequency of their pumping is affected by the intensity of use.

Advantages of septic tanks:

• simple installation;
• safety;
• small installation costs;
• cleaning efficiency manufacturer's guarantee;
• long service life;
• a wide range of;
• low level of soil contamination;
• the possibility of independent arrangement of the entire sewer system.

How does a septic tank work

With a wide variety of products, any septic tank design works almost the same. There are several chambers in the tank where the waste water is treated and removed through a drainage channel or into the soil. The compartments are interconnected by special holes in the upper parts of the walls. Each of them is equipped with gas exhaust ventilation.

Main steps:

• mechanical cleaning from solid waste fractions;
• upholding;
• decomposition of organic matter;
• fermentation and biological treatment with the help of special bacteria;
• gas outlet;
• liquid filtration.

At each stage, a certain degree of filtration occurs in its part of the purification circuit. As a result, wastewater is purified by 90%. The use of an aeration field allows for deeper cleaning.As a result, the purified liquid is reused for economic purposes.

Problems of high groundwater

High is the level of water at a depth of less than one and a half to two meters from the surface. In spring, it sometimes even comes to the surface and floods parts of the territory. Their occurrence is determined before the design of the sewerage system and the choice of a septic tank.

Possible problems and annoyances:

1. Spring surfacing and pushing equipment out of the ground under the influence of soil heaving forces and water pressure.
2. Depressurization and serious damage to the entire sewerage system due to the ascent.
3. The release of sewage from the tank due to flooding (full or partial) in the event of an increase in the level of HW above the location of the septic tank.
4. Environmental pollution due to sewage leakage into the fertile layer or sources of drinking water.

Methods for determining the depth of groundwater

1. Hydrogeological studies carried out by professionals using specialized equipment and tools. This is a complex process that takes a lot of time and is expensive.
2. Self-measurement with a two-meter rod with markings in increments of up to 10 centimeters. A well is preliminarily made on the site for the length of a garden drill. A day later, the rod sinks to the bottom and the wet mark is checked. Measurements are taken over several days during periods of heavy rain or snowmelt. At different values, the smallest values ​​are taken.
3. The study of vegetation on the site. When the water is shallow, reeds, willows, alders, currants, sorrel and others grow well. The proximity of moisture indicates the slope of birch, willow or maple.
4. The presence of open reservoirs near the site, the level of which demonstrates the proximity of the aquifer.The swampy terrain is also a distinguishing feature. In addition, wells where this level can be observed are a good indicator.
5. The advice and recommendations of neighbors who have previously encountered a similar problem will also tell you the depth of the water.
6. Knowledge of the signs and behavior of domestic animals also proves to be useful in determining GWL. Heavy dew in the mornings and thick fog in the evenings testify to the moisture content of the soil. Dogs choose dry areas to rest, mice and insects do not like excess moisture, and cats like to be closer to the water.

Classification and types of septic tanks

According to the principle of work

1. Cumulative - effluents settle in sealed chambers until pumped out.
2. Anaerobic settling - treatment of sedimentary substance with anaerobic bacteria with a degree of purification up to 70%.
3. Biocomponent Plants - Wastewater is attacked by anaerobic and aerobic bacteria to increase efficiency up to 98%.

Based on electricity

1. Non-volatile - without the use of electrical equipment and the need to connect to power sources.
2. Volatile - for normal operation, a constant connection to sources of electricity is required.

By cleaning method

1. Mechanical - impurities settle in the tank.
2. Biological - organic substances decompose under the influence of microorganisms.

By material

1. Plastic - durable and inexpensive devices, but at risk of "floating" with a high level of groundwater.
2. Concrete - reliable structures with a long service life, but requiring special equipment for construction.
3. Metal - universal inexpensive tanks, but with a short service life and susceptibility to corrosion.

By number of cameras

1. Single-chamber - collection of effluents according to the principle of a cesspool.
2. Multi-chamber - a high-quality process with the removal of up to 90% of contaminants.

Criterias of choice

Experts advise what to look for and take into account various factors in order to avoid mistakes when choosing the right equipment:

• geodetic conditions and relief of the site;
• location near water bodies;
• soil type,
• operation mode - permanent or seasonal;
• the volume of stocks;
• structure weight;
• performance;
• throughput;
• tightness;
• reliability at work.

In some cases, with occasional use of a lady or a summer house, it is advisable to choose a sealed storage tank. At the same time, you will have to periodically invite sewers to pump out. However, the risk of swamping will disappear and a filtration field is not needed.

With permanent residence and use of the sewer system, industrial production stations with walls up to four centimeters thick are preferable.

The required wall volume is calculated based on the needs and daily discharge. The advantages of such structures are:

• tightness;
• long service life;
• quality cleaning.

On modern models, sensors for signaling the filling of compartments are installed.

In case of difficulties in determining the optimal parameters, it is better to contact professionals or representatives of manufacturers. For a reasonable fee and quickly, they will mount their unit where necessary. In addition, you can agree with them on regular maintenance of the septic tank, so as not to bother yourself on this issue. At the same time, the cost of annual scheduled maintenance will amount to five thousand rubles.

Where could I buy

Popular models of septic tanks for high groundwater can be purchased at specialized stores or from manufacturers' dealers.They can find the best budget novelties that are presented by the best manufacturers, look and touch, read the description and compare the parameters. Consultants will tell you what septic tanks are, their varieties, how to choose which company is better, which one is better to buy, how much it costs.

How to protect a septic tank from surfacing

Easy-to-install sealed plastic tanks must be securely anchored due to the danger of floating to the surface.

Fixing order:

1. The bottom of the pit is leveled and a sand cushion is poured up to 30 cm, followed by tamping.
2. A reinforced concrete slab with mounting loops is installed or poured from above.
3. The tank is mounted, filled with water and fastened with anchor bolts or cables.
4. The pit is filled with a sand-cement mixture in a ratio of 5: 1 and compacted with pouring layers.

Post-treatment of wastewater will require the arrangement of a filtration well and a cassette. The forced pumping of water will provide a pump. With a daily discharge of 1 m3 of sewage, the area of ​​\u200b\u200bthe cassette should be more than 2 m2. This value increases as station performance increases.

When equipping a filtration cassette (field), it is necessary to remove at least 40 cm of soil over the entire area. The perimeter flush with the surface is fenced with concrete blocks and covered with fine gravel.A tank without a bottom is installed on top with a pipe from a septic tank. The structure is insulated and covered with soil.
