How to prevent winter pipe clogs

It is recommended to prepare for the cold weather even before the onset of frost. It is better to approach the pipelines of a private home in a comprehensive manner, to prepare both the sewer and water pipes, as well as the stormwater system.

The following procedures help to significantly reduce the risk of winter congestion:

• Conducting preventive pipe cleaning, such as hydrodynamic method;
• if necessary, make repairs of emergency sections of pipes;
• If there is no desire to clean pipes, you should at least make sure that the water moves without difficulty, that the runoff is not hindered;
• from the gutters and downspouts to remove all fallen leaves, branches, any debris;
• Cover gutters and other open systems with grates and other mechanical filtration devices;
• Make sure that cooking oil and grease do not get into the sewers because they often deposit on the inside of the pipes and cause blockages;
• Check faucets – it is important that they do not leak, especially if you plan to leave the house for a long time during the winter, as leaky faucets often cause icing, the appearance of ice plugs in the pipes, leading to bursts.

It is also possible to perform a teleinspection of the pipelines.

Hydrodynamic flushing of pipes

If patency testing reveals that runoff is slow, or if a clog has already developed due to frost or simple buildup of deposits, hydrodynamic pipe flushing is recommended.

The technology is the introduction through the revision in the pipeline of a special flexible hose, at the end of which is a head with nozzles. Water is fed into the hose under high pressure. Thin jets of water are forced out of the head. The hose advances inside the pipe, and the jets wash away all kinds of deposits – fat, salt, and any build-up is also knocked down.

After the main blockage is cleared, the hose is moved back in, but the water is not shut off. The jets, continuing to beat on the inner surface of the pipe, wash away the remains of impurities from it, which go into the sewage well or to another point, from which it will be easy to remove all the solid impurities, silt. In this way the original permeability of the pipe is restored.

If the sewer is clogged with an ice plug, hot water is fed into the hose instead of cold water. For additional effectiveness, a solution of special reagents can be used that dissolve dirt and deposits, making it easier to clean. The main thing is to correctly calculate the concentration of compositions so as not to damage pipes and other elements of the sewer system. Therefore, it is important to contact professionals who have the necessary knowledge and licenses.

Wastewater treatment in a private home: septic tank or loos? All these systems are based on different principles of operation. The mechanical method of purification involves sedimentation and subsequent filtration of wastewater. A more modern biological method is based on the processing of waste with the help of a colony of beneficial bacteria with a purification efficiency of up to 98%. As a result of these processes, the output is a technical liquid, which can be used in the domestic needs on the site.

General Information

Comparative characteristics of the most common models of sewage treatment plants differ in a number of parameters:

• total capacity, indicating the maximum volume of effluent the plant can treat in a day;
• maximum salvo discharge is responsible for the volume of liquid taken by the system at one time while using all the sanitary appliances connected to the sewerage system;
• the depth of piping, the greater this parameter, the higher the final cost of the station;
• materials of manufacture of the body, can be concrete, polypropylene or fiberglass;
• the need to connect to electricity, all modern septic tanks are equipped with pumps, aerators and other devices that require a stable supply of electricity for functioning method of disposal, for permeable soil with a low groundwater table choose gravity method, and for impermeable soil and high groundwater – forced discharge of treated liquid;
• Type of housing, selected individually, based on the characteristics of the terrain, there are stations in horizontal and vertical design.

Bacteria

Modern wastewater treatment systems for private homes involves several types of bacteria for effective processing of waste. Aerobic beneficial microorganisms require a constant supply of air into the system for efficient activity, anaerobic bacteria can also work in the absence of oxygen.

Treatment facilities for private homes using several types of bacteria, are able to clean the waste up to 98%, obtaining at the same time a colorless technical liquid output without odor. To understand what kind of sewage treatment plant is suitable for a particular situation, you need to review the options for sewage in a private home.

Septic tanks with anaerobic treatment method

Such systems are based on the filtration of wastewater by mechanical means and process organic compounds through the action of anaerobic bacteria. Wastewater enters the intake compartment through the sewer line coming from the house. The heavy fractions are trapped and remain at the bottom. The liquid then flows into the next chamber with light fractions remaining on the surface. Here, the effluent undergoes a thorough treatment and the large compounds settle out. In the next stage, the liquid enters the third compartment where the organic matter is processed by anaerobic bacteria.

After that, the clarified liquid is removed from the septic tank through the pipes to the filtration field, which consists of several layers of crushed stone and sand. This type of septic does not require power from electricity and is cheaper relative to energy-dependent models.

Septic tanks with aerobic method of treatment

Overview of wastewater treatment systems in a private home, equipped with aerators. In these systems (VOC) at the same time involved several ways of processing household waste. Cleaning is carried out in several stages, combining mechanical action, anaerobic and aerobic. The sewage treatment plants require connection to a power grid, but are completely silent. In case of power outages go to the mode of operation of a simple septic tank of the accumulation type.

Autonomous biological treatment of sewage and domestic sewage for installation in a private home does not require the additional organization of the filtering fields. Wastewater is purified up to 98% and discharged directly into the ground with a special drainage ditch. There are many modifications on the market, where the spent sludge can be pumped by yourself, without resorting to the services of sewage trucks and without the need to provide access roads to the station.

Principle of operation:

Domestic wastewater enters the reception compartment through the sewage pipe coming from the house. It undergoes mechanical treatment – sedimentation. Large compounds remain at the bottom, where they are processed and dissolved by anaerobic bacteria.

The liquid then enters the aeration tank, where oxygen is continuously supplied.

The fine air bubbles break down the debris into smaller particles. The oxygen-rich medium reacts with the activated sludge, thereby triggering the necessary oxidative processes.

After that, the liquid flows to the secondary settling tank, where the waste sludge settles to the bottom and the water is clarified. From here, it is discharged into the drainage ditch by the selected method of discharge.

From a special compartment – stabilizer, you need to regularly pump out the spent sludge, which can later be used as a useful biological fertilizer on the site.

What is better to choose: LOS or septic tank?

• safety for the environment;
• high level of effluent purification, reaching 98%;
• complete absence of any unpleasant odors;
• possibility of disposal of recycled liquid directly into the soil;
• no need for a regular call of sewage trucks and additional costs for the maintenance of the station.

The option of sewerage with filtration fields is difficult to implement in clay soil, while VOC can be installed on any site, without restrictions. In areas with a high level of groundwater cannot be arranged filtration fields, so the only way out would be to install an aerobic septic tank with a forced drainage system.

What to consider when choosing a septic tank

Life out of town today is chosen by many city dwellers, while many are not prepared for the difficulties that arise, and this is primarily the lack of municipal infrastructure. To solve the problems of water supply and wastewater disposal have to decide by different methods, and it is important in this case to minimize the risk of ingress of sewage into the ground and water bodies. The degree of purification of the liquid discharged into the pond must comply with the provisions of legislative acts governing the protection of the environment. If the water purified in the septic tank will be used for the second time, the sanitary standards already come into force.

The main advantage of local wastewater treatment systems can be called the most effective treatment for re-use of water for technical purposes, including watering. When choosing a wastewater treatment system, you should consider the following factors:

• the number of people living in the house;
• frequency of residence;
• the features and composition of the soil;
• the characteristics of the terrain;
• the level of occurrence of deep water;
• Frost depth of the ground.

Local sewage treatment facility is selected depending on the specific conditions and characteristics of the area. It could be a storage tank, sufficient to cope with the wastewater in a cottage, designed for seasonal residence, settling tanks and complete biological treatment plants. The latter guarantee almost one hundred percent sewage treatment and significantly reduce the frequency of use of special equipment. Therefore, when installing the septic tank has to take into account the volume of the sewage truck, and the standard model can accommodate 3.75 “cubic meters” of sewage. It remains to know how to calculate the volume of the septic tank, taking into account the main factors.

Calculating the volume of the septic tank for a private home

The main task of the septic is the disposal of residues of vital functions, so the device must have the capacity to accumulate and effectively clean the entire volume of sewage. To avoid overfilling the chambers must make the correct calculation of the volume of septic tank for a private home. It would seem that there is nothing complicated about it – you just need to add up the volume of all the chambers of the disposer, but it would be too simple.

In fact, it looks a little different: the volume of the first chamber is calculated from the level of the bottom to the overflow pipe, while the usable space of the second chamber is all that is between the bottom and the drain pipe. In addition, you should take into account that over time in the first tank accumulates a large number of solid particles, which occupy one fifth of the usable space. Therefore, when calculating the liquid component, these 20% must be subtracted from the total volume. Now, to understand what should be a septic, it remains to compare the expected amount of sewage.

The daily flow rate of water for the average user is 200 liters, or 0.2 m3, but according to the rules of the minimum volume should be calculated with a margin of 3 days. Thus, for a family of 3 people, the approximate flow of water is 1.8 m3, and that’s not counting the 20% that must be added to the bottom sediment.

The formula for calculating the volume of the septic tank for the summer house

Sanitary standards indicate that the discharge of treated water outside the device should be carried out no more often than once every two weeks. When making calculations, no one uses this provision, because in this case, for a family of 4 people you need a device, the volume of 8 “cubes”, at least. It is also not a fact that each resident spends 200 liters of water per day, and experts and does not believe that we can proceed from the indicator in 0.1 m3/day. In this case, 3 people will need a “cubic” septic, but the installation of such devices are not welcome.

There are other exceptions to the rules in the form of an unexpected increase in the number of residents and expanding the composition of household appliances (buying a dishwasher, for example). Therefore, to calculate the required volume of septic tank should take into account possible changes. Experts recommend using a more precise formula:

V septic = (Number of tenants * 0.2 + 0.2) *2

To give a margin of safety should add another flow for one conditional person, then multiply the result by two, counting on the fact that some residents are very fond of taking water procedures. Thus, for 5 people, for example, the minimum volume of septic tank is 2.4 m3, the ideal solution for 6 people will be the disposer of 2.8 m3. As practice shows, these are real figures that allow you to unmistakably buy a septic tank that will make living in the house as comfortable as possible.

It is even easier to calculate the necessary volume of septic tank for dacha, designed for occasional residence. In this case, most often installed low-function hoarders, which should choose, given how many cubes can dispose of at a time, the sewage removal equipment.
