In what ways can you pump out the drain pit

The answer to the question of what methods can be used to pump out the drain pit is of particular interest to the owners of country houses and summer cottages where there is no centralized sewage system. A cesspool, as a simple sewerage system, copes well with the collection of sewage. However, over time, its capacity is filled with them, and the problem of their removal becomes acute. You can solve it in different ways.

What is the reason for the need for pumping

The need to pump out the drain pit arises when it is filled in the following circumstances:

  1. Scheduled pumping out. It is expensive and not economically justified to build a drain pit or septic tank of huge dimensions, and it is difficult to find a place. It is designed so that the filling occurs after a certain time. The minimum period is 3-4 months, and in small summer cottages it can reach several years.
  2. Accelerated filling caused by unplanned runoff volume. In leaky septic tanks, the bottom can be silted up or the walls overgrown.
  3. Failure of the filtration system.
  4. Natural phenomena (heavy rainfall, flooding).
  5. The appearance in the cesspool of hazardous substances and microorganisms that threaten with infections and harmful emissions.
  6. The emergence of a danger of accumulation of gases (amber).
  7. Stench.
  8. Danger to fertile soil.

An unscheduled pumping out will have to be carried out if it is necessary to repair the sump. This may be due to a violation of the tightness or deformation of the structure.

Pumping methods

It is recommended to pump out the waste pit when it is 2/3 full. Work can be done by hand using pumps, devices or special tools. Complete cleaning without problems for the owner is provided by a team of suction trucks.

Evacuation with pump

One of the most efficient ways to pump out is to use a pump. A special fecal pump equipped with an automatic control and monitoring system is suitable for this purpose. Such submersible devices can be placed in a drain pit and turned on as needed. In principle, conventional water pumps can be used, but there is a risk of clogging up quickly. Filters help eliminate this nuisance.

Another essential element when pumping out is a sealed reservoir of sufficient capacity. Liquid from the pit is pumped into it, and then the sewage is transported to the place of disposal. The choice of the pump and the reservoir is made, first of all, according to the volume of the drain pit. Main technical characteristics: performance and immersion depth of the pump.
For pumping out drain pits, the following pumps can be recommended:

  1. Aquatica 773411. The device can be submerged to a depth of 5 m. Automatic mode is provided. The cost is from 6000 rubles.
  2. Sprut V180F is a universal pump. Price - from 5200 rubles.

The advantages of pumping: high productivity, speed, pumping quality, process automation.

Among the disadvantages are: the need to purchase equipment, electricity costs, the need for transportation to the place of disposal, energy dependence.

Do-it-yourself pumping without a pump

The easiest and cheapest way is to manually clean the sewer pit. Its implementation requires time and physical strength. A bucket is lowered into the pit, with the help of which the liquid fraction rises upward. After removing it, shovels are used to clean up viscous and solid substances. The raised sewage is poured into a tank, which is then transported to the place of authorized disposal.

The advantages of the technique are: no costs, ease of implementation and availability.

Cons: low productivity, significant expenditure of physical strength, duration of the process, stench during work.

Biological agents

The main disadvantage of the above methods is the need to transport sewage to the place of permitted disposal. Such activities are licensed, and therefore only organizations that have such a license can transport containers with effluents. Great difficulties arise in areas with high environmental requirements.

Chemical and biological methods of cleaning them can ensure the disposal of wastewater at their site. To do this, special agents are poured into the cesspool that chemically neutralize harmful components. Even more effective are special microorganisms that process hazardous substances. After such treatment, the sewage becomes fertilizer and, after filtration, can be discharged directly into the soil.

Nitrate oxidants, formaldehydes, and ammonium compounds are used as chemical reagents. Among biological preparations, the following stand out: biological agent Weist Treat, KALIUS, "Sam to itself Zolotar".

The advantage of the method: elimination of the transportation of sewage, obtaining fertilizer.

Disadvantages: sensitivity to some aggressive substances, inability to influence plastics, temperature limitations.

Waste disposal machine

Despite the possibility of self-pumping drain pits, many homeowners prefer an agreement with a specialized organization that has sewage equipment. To remove sewage, a machine with a feces tank and a powerful pump is fitted. In 30-40 minutes, even a large pit is completely cleaned. Then, with the help of water jets, the walls are cleaned.

The owner does not exert any effort and does not think about the disposal of sewage. He only has to pay for the work - an average of 750-900 rubles per 1 m3... A contract with a sewer company can be concluded for a one-time service or long-term service according to an agreed schedule.

The main advantages of sewage disposal: speed and quality of work, full guarantee of environmental safety, the ability to clean large pits, independence from air temperature.

Disadvantages: financial costs, the need for access roads, noise during the operation of equipment, which can cause complaints from neighbors.

The choice of the optimal method depends on the specific operating conditions of the sewage pits. It is determined by the price / quality / speed ratio. In small summer cottages of periodic use, filling the pit can take several years. In such conditions, it makes no sense to buy a pump. You can use a one-time flusher service if there is a convenient entrance. The best option is manual cleaning on your own. Cheap and reliable.

With active use of a country house with the need to clean the pit several times a year, it is best to install a fecal pump and use chemical or biological treatment. The lifted mass (odorless) can be sent through the filter system directly into the soil on the site.

If large pits need to be cleaned at intervals of no more than 4-5 months, then it is most beneficial to conclude an agreement with a sewer company. It should be borne in mind that with more frequent pumping, the costs of sewage treatment will not pay off.
