The answer to the question by what methods it is possible to pump out the drain pit is especially interesting for owners of country houses and cottages where there is no centralized sewage system. The cesspool, as the simplest sewer system, copes with the collection of sewage. However, over time, its capacity is filled with them, and the problem of their removal arises sharply. It can be solved in different ways.
What determines the need for pumping
The need for pumping the drain hole arises when it is filled in the following circumstances:
- Planned pumping. To build a drain pit or septic tank of enormous size is expensive and economically unjustified, and the place is difficult to find. It is designed so that filling occurs after a certain time. The minimum period is 3-4 months, and in small cottages it can reach several years.
- Faster fill due to unplanned flow. In leaky septic tanks, siltation of the bottom or wall overgrowth is possible.
- Failure of the filtration system.
- Natural phenomena (heavy rainfall, flooding).
- The appearance in the cesspool of hazardous substances and microorganisms that threaten infections and harmful emissions.
- The appearance of the danger of gas accumulation (amber).
- Stench.
- Danger to fertile soil.
Unscheduled pumping will have to be carried out if it is necessary to repair the cesspool. 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 filling it for 2/3 of the volume. Work can be done with your own hands using pumps, devices or special tools. Complete cleaning without problems for the owner provides a team of trash cans.
Pumping off with a pump
One of the most effective pumping methods is to use a pump. A special fecal pump equipped with an automatic control and monitoring system is suitable for this purpose. Such immersion devices can be placed in a drain hole and included as necessary. In principle, you can use ordinary water pumps, but there is a risk of their rapid clogging. Eliminate this trouble filters.
Another necessary element during pumping is a sealed tank of sufficient capacity. Liquid is pumped into it from the pit, and then sewage is transported to the disposal site. The choice of pump and reservoir is made, first of all, by the volume of the drain pit. Main technical characteristics: productivity and depth of immersion of the pump.
The following pumps can be recommended for pumping drain pits:
- Aquatica 773411. The device can be immersed to a depth of 5 m. Automatic mode is provided. Cost - from 6000 rubles.
- Sprut V180F is a universal pump. Price - from 5200 rubles.
Advantages of pumping: high productivity, speed, pumping quality, process automation.
Among the shortcomings stand out: the need to purchase equipment, the cost of electricity, 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 waste pit. In its implementation, time and physical strength are needed. A bucket is lowered into the pit, with the help of which the liquid fraction rises up. After removing it, shovels are launched to clean viscous and solid substances. Raised sewage is poured into the tank, which is then transported to the place of authorized disposal.
Advantages of the methodology: no costs, ease of implementation and affordability.
Cons: low productivity, significant expenditure of physical strength, the duration of the process, the stench during operation.
Biological products
The main disadvantage of the above methods is the need to transport sewage to the place of permitted disposal. Such activity is licensed, and therefore only containers with such a license can transport containers with drains. Great difficulties arise in areas with high environmental requirements.
Chemical and biological methods of their treatment can provide waste disposal at their site. For this, special products are poured into the cesspool that chemically neutralize harmful components. Special microorganisms that process hazardous substances are even more effective. After this treatment, sewage becomes fertilizer and can, after filtration, be discharged directly into the soil.
As chemical reagents, nitrate oxidizing agents, formaldehydes, ammonium compounds are used. Among the biological preparations, the following are distinguished: Wayst Trit, KALIUS, "Zolotar Himself".
The advantage of the method: the exception of the transportation of sewage, obtaining fertilizer.
Disadvantages: sensitivity to certain aggressive substances, inability to affect plastics, temperature restrictions.
Cesspool machine
Despite the possibility of self-pumping drain pits, many homeowners prefer a contract with a specialized organization that has sewage equipment. A machine with a feces tank and a powerful pump is fitted to remove sewage. In 30-40 minutes, even a large pit in volume is completely cleared. Then, using a water jet, the walls are cleaned.
The owner does not apply any forces and does not think about the disposal of sewage. He only has to pay for work - an average of 750-900 rubles per 1 m3. The contract with the company-cesspool can be concluded for a one-time service or long-term service according to the agreed schedule.
The main advantages of sewage disposal: speed and quality of work, a 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 operation of the equipment, which can cause claims of neighbors.
The choice of the optimal method depends on the specific operating conditions of the waste pits. It is determined by the price / quality / speed ratio. In small cottages of periodic use, the filling of the pit can take several years. In such conditions, it makes no sense to buy a pump. You can use the one-time service of scavengers, if there is a convenient entrance. The best option is manual cleaning on your own. Cheap and reliable.
With the 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. Raised mass (odorless) can be sent through the filter system directly to the soil on the site.
If it is necessary to clean large pits with a frequency of no more than 4-5 months, then it is most advantageous to conclude an agreement with the company. It should be borne in mind that with more frequent pumping, the cost of sewage disposal does not pay off.
