How to get rid of sludge in a cesspool

The accumulation of silt in a sewer pit often creates problems for owners of private houses and summer cottages. You can clean the waste container in several proven ways. Some methods involve the implementation of do-it-yourself cleaning, while others - using special devices or industrial means.

Signs of a problem

Silting of the bottom of the cesspool and its rapid filling often occurs due to the deposition of fat in the drains. Sewage waste, in combination with cold water, thickens the fatty compounds, which clog the pores of the soil and the drainage of the drain pit, as a result of which the water ceases to go into the soil.

The main sign of a sewage problem is a decrease in the volume of the tank. The waste container starts to fill up quickly, which leads to more frequent pumping of sewage waste. An unpleasant pungent odor appears due to a violation of the decay process.

Dry cleaning

If the problem occurs in winter, chemicals will help to fix it.

Their undeniable advantages:

• action in low temperature conditions;
• resistance to aggressive environment;
• the ability to decompose different types of sewage waste;
• quickly eliminate unpleasant odors.

The modern market offers a large number of nitrate oxidants that do not harm the environment and human health. The mechanism of action of such chemicals is similar to the work of nitrate fertilizers, which makes it possible to use sewage waste for feeding crops.

The use of nitrate oxidants contributes to:

• fast fat liquefaction:
• reducing the volume of solid waste:
• removing unpleasant odors.

Cleaning the cesspool in this way does not require large cash costs.

The cleaning procedure is carried out in several stages:

1. Measure the required amount of the chemical in accordance with the instructions.
2. Pour the agent into a sewer container and close it. The average duration of liquefaction and dissolution of waste is 3-6 hours.
3. Sewage waste is pumped out using a fecal or drainage pump.
4. The pit is washed with clean water.

This method has some disadvantages that you should definitely pay attention to:

1. They are not suitable for plastic drums and open septic tanks.
2. The effectiveness of the product increases gradually and depends on the frequency of its use.
3. After using such preparations, it is not recommended to carry out cleaning with bioactivators for a long period, since chemical compounds help to neutralize bacteria.

Biological cleaning

Biological preparations give a good effect when removing sewage sludge. They include anaerobic and aerobic microorganisms that process sludge, fatty compounds and human waste.

Specialty stores offer a wide range of products in powder, tablet or liquid form. Among the advantages of such drugs:

1. High efficiency, which reduces waste by 30%.
2. Fast elimination of characteristic odor.
3. Harmless to human health and the environment.
4. Suitable for both closed and open pits.

Biological cleaning is carried out according to the following scheme:

1. The required amount of biological substance is poured into the sewer pit (the recommended duration of cleaning is 7-10 days).
2. Liquid waste is pumped out.
3. Rinse with clean water under high pressure.

When cleaning the sewer pit in this way, the constant use of bacteria is possible. For this, an additional portion of microorganisms is placed in the container.

The effluent from the biological treatment of the tank can also be used as fertilizer in the garden and in the garden.

Mechanical cleaning

It suggests different ways to remove sewage sludge.

Manually

The cesspool can be manually cleaned. Although the method is not easy and unpleasant, the result will be good. For cleaning, use a shovel, rope and special clothing and shoes.

Sequence of work:

1. Drain the waste container using a bucket and rope.
2. Having gone down into the pit, they take out the accumulated silt with a shovel and use a bucket on a cable to lift it up.

This method is suitable for small sewer pits.

By pump

To remove sludge from the pit, perform the following actions:

1. A fecal or drainage pump is immersed at the very bottom or in the upper layer of the drain (depending on the type of technical device).
2. A hose is pulled from the sewer tank into the drain pit (additional).
3. After the cleaning process is completed, mechanical removal of sludge and fat deposits from the bottom and walls is carried out. Use metal brushes and buckets.
4. The pit is filled with clean water.
5. The pumping and disposal of water is repeated.

To enhance the cleaning efficiency, chemicals are added to the cesspool.

Waste disposal machine

For quick cleaning of the waste tank, the services of a sewer are often used. Professional machines are equipped with sludge pumps, which make it easy to remove sludge deposits.

This type of mechanical cleaning gives good results. It can be used for containers made of concrete, metal and stone. Its main disadvantage is the lack of a long-term effect.

Preventing the problem

In order to prevent siltation of the bottom of the sewer pit and reduce the number of cleanings, the following preventive measures are taken:

1. Sewage waste is pumped out of the cesspool in a timely manner.
2. The walls and bottom are regularly washed with water under strong pressure.
3. For the purpose of prophylaxis, biological and chemical agents are used in the summer, which prevent the formation of fatty deposits in the sewer tank and help to eliminate the unpleasant odor.

If you follow such measures, then the autonomous sewage system will function reliably for a long time.
