Probably, any owner of an individual system of water supply and sewerage faces this kind of problem one day or another. At some point, siltation of the cesspool occurs. And that means that the pit fills up very quickly, and its pumping becomes a very expensive pleasure. Let's try to understand the causes and consequences of this phenomenon.
Causes and signs
Cesspools are divided into several types:
- A cesspool without a bottom. This is a simple pit dug in haste. The biggest plus is the cost of execution and mobility. You can dig it out manually, at any depth and in any place. The downside will be: very fast filling, unpleasant odor, negative effect on the soil.
- An isolated pit with an open bottom. Such pits are equipped with concrete rings or the walls of the pit are laid out with any insulating material. But the bottom is left open, which ensures the outflow of sewage strictly down.
- Septic tank. This is a device that releases only purified water into the environment, but the residues are pumped out already cesspool by car.
Well, the signs of siltation are quite simple and unpretentious - cesspool the pit fills up very quickly and gives off an unpleasant odor.
Of course, there are a great many methods for cleaning a cesspool. You just need to choose the best one for your problem.
Dry cleaning
To clean the cesspools, products containing ammonium salts or formaldehydes. But they can be used only in the warm season. There is an alternative in the form of nitrate oxidizing agents. After their use, you can even use the waste as fertilizer for the soil. The only negative point will be that the waste treated with chemicals will not be very useful for secondary use as fertilizer after the cleaning residues have been pumped out.
But chemical methods for cleaning cesspools have numerous cons - they toxic toxic. Therefore, it is worth thinking very seriously before undertaking such methods, although they are very cheap.
For chemical cleaning, most often used:
- formaldehydes that are very affordable, but directly proportional in terms of harmfulness and toxicity both for soils and for humans. For these reasons these drugs are rarely used today, because they can provoke cancer;
- nitrates perfectly break down all organic residues contained in cesspools. After cleaning with nitrate oxidizing agents in the correct dosages, the purified contents of the cesspools turn into high-quality and inexpensive fertilizers for agricultural use. But these drugs are quite expensive to purchase;
- ammonium cleaners for cesspools are very effective, but to this day have not been fully studied, so it's too early to talk about their dangers or benefits. But there is no doubt that they bring a long-term effect.
The only negative chemical cleaning for all preparations can be considered that the chlorine entering the cesspools greatly reduces their effect. Therefore, if you use the chemical method of cleaning the cesspools of your houses, is worth to abstain from the use of chlorine-containing preparations for washing dishes, washing clothes and cleaning plumbing.
Biological cleaning
Bioactivatorsbased on live bacteria. This is precisely the basis of drugs that decompose and recycle everything that is full of a cesspool. These bacteria reduce the contents of the cesspool by almost 30 percent.Along the way, these living organisms clean the walls of the cesspool itself, providing better absorption of fluid into the soil layers that surround the cesspool. These living bacteria do not emit harmful components, which is a significant advantage in using live bacteria to clean cesspools.
These biological cleansing additives come in several forms. Everyone can choose from the abundance of tablets, gels and special fluids on the market, as well as granules and powders. These microorganisms will make the sewage from the cesspool completely harmless to the environment. After treatment with biological organisms, these waters can even be used to water the same gardens and gardens. But if drains of water with chlorine or a washing machine and dishwasher box are drained into the same cesspool, then the properties of microorganisms are significantly reduced.
Mechanical cleaning
Mechanical cleaning of the cesspool is not particularly difficult. For this Total we need a bucket and a rope corresponding to the depth of the cesspool. The procedure itself is unpretentious. The contents of the cesspool are simply scooped out with a bucket. The main thing is not to forget to change into clothes that protect against pollution and unpleasant odors. Another prerequisite will be the protection of the respiratory tract from ammonia and methane fumes, which can become dangerous to the human body. After all, the press repeatedly publishes notes on fatal poisoning when cleaning cesspools.
Self cleaning of the cesspool has always been a dreary, long and dangerous. Therefore, many users of cesspools who need mechanical cleaning, put a special fecal pump. This device many times simplifies this procedure and makes it practically safe. This pump is also called sludge suction. It is installed on a machine that drives up to the cesspool and simply pumps out the entire contents of the cesspool through a wide hose. True, the smell after this manipulation has been in the air for quite a long time. But this method is the most eco-friendly.
And of course, a classic of the genre, pumping out a cesspool cesspool cars. Everything is pretty trivial here. You just need to find a company that provides such services. Call specialists for the date and time you need and calmly wait for this service to be provided. You just have to pay attention to the fact that the service of the scavengers provides services only if your cesspool is filled to two thirds of the total volume. Otherwise, the installation simply cannot work. Therefore, it is worthwhile to clearly monitor the volume of filling the cesspool. Otherwise, everything will become very problematic and costly.
Problem prevention
Of course, filling a cesspool is a mandatory phenomenon, but there is a way to make it happen as rarely as possible. To do this, it is necessary to equip the bottom of even the simplest cesspool with filtering elements: gravel and sand - he always underlie all filter elements of cesspools and septic tanks. Therefore, do not underestimate the importance of the filter in the cesspool.
Another option would be an additional outflow of liquid water from the cesspool. For this, a sewer pipe is installed, which falls exactly on half of the dug out pit. And she is diverted at an angle to the side. This ensures the outflow of liquid water away from the main storage. This method is also quite effective. True, quite laborious. The pipe must not only be taken to the side, but also created under it the same filter pad as at the bottom of the cesspool. First, a hole is dug up for the entire length of the outlet pipe, the bottom is laid agrofibre or sand mixed with gravel. A pipe is placed at this angle at an angle, which is sprinkled with gravel of a large fraction, after which it is covered with sand and covered with soil.Such arrangement of a cesspool will maintain its purity for a sufficiently long time. Yes, and an unpleasant odor can be avoided for a long time.
Of course, it will not be possible to get rid of siltation of the cesspool forever. But this problem can be avoided for a long time, if you apply some of the available methods described above. The main thing is to choose exactly those methods that are suitable specifically for your site.
First you need to decide on prophylactic methods, think over all available methods for cleaning the silting cesspool, and then create a cesspool for a comfortable and convenient stay on your site.
