The sewer cesspool fills up quickly - what needs to be done?

Local sewer networks for private houses include either cesspools or septic tanks. The simplest design is a cesspool in which sewage is simply collected. Partially, water penetrates into the layers of soil, but the bulk and sewage must be pumped out. The frequency of pumping depends on the volume of the well and on the ability of water to pass through the soil. But, as often happens, even such a simple tank starts to work poorly. Therefore, you can often hear the question, the cesspool is quickly filling up - what to do?

Reasons for the rapid filling of the cesspool

There are many reasons why the water in the cesspool does not go away. One of the main ones is the volume of the reservoir, which does not correspond to the amount of sewage. That is, at the very beginning, the developer planned that drains from the bathroom and toilet would merge into the cesspool. But over time, they were joined by a bathhouse, a summer kitchen, a washing machine and dishwashers. To solve this problem, you just need to increase the number of pumpdowns.

The second reason is the level of groundwater. Unfortunately, this indicator is neglected by many developers. Many do not consider it necessary to find out at what depth these waters lie. But it is they, as practice shows, that are the cause of the overflow of sewer wells. Especially during rainy and snowmelt periods. After all, sewage is often built in the summer, and at this time the level of groundwater is the lowest. Therefore, when digging a hole, the foreman does not encounter a water layer.

If the pit often overflows, it is necessary to increase the number of pumping

It started to rain in autumn, and the pit began to fill up more intensively. Water pours through the lid and hatch, sewage spreads over the territory of the site, an unpleasant smell appears. This problem can be solved in the same way as in the first case - to increase the frequency of pumping out wastewater.

Types of cesspools

This is another reason why the water in the cesspool does not go away. It is identical to the first reason, but there are differences. There are two types of sewer wells: hermetic and non-hermetic. In the first case, this is a reservoir, the volume of which must be accurately determined. There is a formula by which the volume is determined. It is based on:

  • the number of people using the sewer system;
  • the amount of water consumed by one person;
  • the frequency of pumping out the cesspool.

For example, three people live in a house, it is planned to pump out once a month, that is, every 30 days. A person consumes 200 liters of water (0.2 m³) per day. The volume of the pit will be equal to: 3 × 30x0.2 = 18 m³. If you increase the number of pumpings, you can reduce the volume of the tank. True, the services of a sewage truck are not cheap. You can also pump out sewage with your own hands, using a fecal pump, in extreme cases, a bucket with a rope.

Self-pumping the contents of the pit

Attention! Pumped waste must be disposed of in certain places specially allocated for this.

As for leaky cesspools, the number of pumpings in it is less due to the fact that part of the water seeps into the ground. But even such constructions are subject to overflow. The main reason for this is oil and fat deposits, small polymeric materials and films, hair, animal hair. All this does not rot and settles to the bottom and walls of cesspools, making them airtight.

Solution of the siltation process

So, if a cesspool silted up - what to do? There are several options for solving this problem.

Pit filled with water

First of all, you need to pump out sewage. Empty the pit to the end, while trying to pump out the silt that has settled to the bottom. Often it becomes very dense, and even a sewage truck cannot pump it out. Therefore, before pumping it is necessary to gut the silt with any long object. It can be a pipe, a board, a rail, and so on. The sludge becomes soft, part of it rises into the water, so some volume will be pumped by the pump.

There is another way to approach this problem. First, pump out dirty water from the pit, and then pump clean water under pressure, washing away fat and oil deposits from the walls. A very effective measure. After that, pumping is carried out, and clean water is poured again, with the help of which the silt deposits located at the bottom of the pit are liquefied. After a couple of hours, the hole must be emptied again.

There is another option, in which it is not necessary to pump out sewage. To do this, you can use chemicals for cesspools. But before cleaning a cesspool without pumping out, it is necessary to choose the right chemical cleaner.

There are three types.

  1. liquid formaldehyde solution. A highly toxic drug that is now banned for use. Although it is very effective and inexpensive.
  2. Nitrate type oxidizers. With their help, any waste is liquefied, in addition, this drug is environmentally friendly, but it has the highest price of all the chemicals offered for cesspools. By the way, oxidizing agents do not react to aggressive environments, they destroy all organic and inorganic impurities in any wastewater.
  3. ammonium compounds. The same effective preparation, but practically loses its qualities in aggressive environments (with a large amount of chlorine, detergents).

If the water in the cesspool does not go away, then you just need to pour the selected and purchased chemical preparation inside. It will begin to liquefy the silt deposits, turning them into fine suspensions. That is, a chemical reaction will occur, one of the residual components of which will be carbon dioxide. Therefore, pouring the chemical into the well, care must be taken that the gas can freely leave it. For example, you just need to leave the hatch open.

After a certain time, the contents of the cesspool must be pumped out along with the liquefied sludge. After that, the walls of the tank are washed with clean water under pressure. And the pit is again ready to receive drains from the sewerage system and not overflow.

Answering the question of how to clean a cesspool without pumping out, one more option can be offered. To do this, you will have to use biopreparations. They simply fall asleep inside the well, where putrefactive bacteria come to life and begin to process organic matter. If a sealed tank was installed for a private house, then anaerobic bacteria should be poured into it, which feel good without oxygen. If the capacity for the cesspool is leaky, then aerobic bacteria are filled up, which die without oxygen.

Attention! When arranging a cesspool for a private house, it is necessary at the beginning of its operation to immediately start putrefactive bacteria. Thus, all the problems associated with its silting will be solved immediately.

Frozen cesspool

If the water in the cesspool does not go away in winter, and it overflows, then this is a guarantee that everything inside is frozen. What to do in this case? Of course, the first step is to melt the ice. If it is not very thick, then you just need to pour hot water into the pit.

But if it is thick, then hot water will not solve this problem. Therefore, it is necessary to come up with various methods of defrosting. For example, use a blowtorch or a gas burner. You can install a heat fan on the manhole cover so that it directs the flow of warm air into the well. In a few hours of work, the drains will thaw - that's for sure. The time will depend on the thickness of the ice. Someone offers various home-made devices that run on electricity. Dangerous things, and if you are not an electrical specialist, then it is better not to use them. And the effectiveness of their work is highly questionable.

The best solution so that the cesspool does not freeze is to insulate it. Fortunately, today manufacturers offer a large number of different heat-insulating inexpensive materials and technologies.

Cleaning cesspools and toilets is a basic requirement for their smooth and trouble-free operation. If you approach this issue competently, then the sewerage of a private house will work efficiently without creating problems.
