Sewage cleaning today.

A well-developed sewerage system contributes to the ecological and sanitary safety of the surrounding area. Waste disposal of human activities has long been a serious problem.

One of the main procedures that allow maintenance of the condition of all sewerage elements in proper condition is the cleaning of the sewage system. Depending on the type of pollution, it is realized in several ways. According to the generally accepted classification, there are three: mechanical, thermochemical and hydrodynamic. Manually, with the help of mechanical tools (peaks and cutters), it is easiest to remove outside dimensional objects that fall inside the pipe. In some cases, the implementation of such a method can be problematic. Especially if the pipes lie at a great depth.

The thermochemical method shows the greatest efficiency when removing stale fossilized blockages by the total action of water heated to high temperatures and aggressive chemical compounds. This method is used most often when other ways to soften and eliminate sewage sludge failed.

Sewage cleaning with a high head of water, passing through a special nozzle, is usually called a hydrodynamic method. It is realized by a channel washing machines. Due to its efficiency and simplicity, it enjoys the greatest popularity and is in high demand when removing blockages at various sites.

Sewage cleaning above the indicated methods should be carried out taking into account the features of the object and the type of contamination. The final choice always rests with the performers; therefore, it is necessary to attract specialists with sufficient level of professionalism to the works on sewerage maintenance. Attempts to self-clean the sewer are fraught with unpredictable and sometimes financially costly consequences. Remove the blockage itself is possible only in extremely rare cases, and even then at an early stage of its occurrence. This is evidenced by many years of practice.

Leak Detection from Plumbing Experts

As a homeowner, you should be aware of the signs of a leak. When you hear water running while all the faucets are off, it’s a sign that there is a leak. Another sign of a leak is the water marks that develop where the leak is. a water stain can appear on the wall, ceiling, and floor which can make the leak detection easy. This is the case for simple leaks from the plumbing system in the plumbing system, but for more major leaks such as slab leaks, it’s harder to find the source of the leak. The only sign you typically notice with the more hidden leaks is the rise in your water bill. These hidden leaks affect large pipes, so the amount of wasted water will significantly raise your water bill and hurt your pocket.

The sewerage system of a private house, even if it is connected to a central sewage system, has its own characteristics. You must learn about these features, because it is often the owner of the house who has to act as a plumber. The correct operation of the sewage system will allow to avoid extra effort and hassle.

Any type of sewage system does not allow largw items, as well as all kinds of paper, hair, fat (fat food). To this end, it is necessary to equip the indoor restroom special boxes (box) for the collection of used toilet paper.

The design of the grease trap

When going down the drain, hair knots and tangles in the food fat and becomes difficult to remove (even with the aid of hot water) from the tube. Eliminated during the operation of sewage entering the hair into it, you can use the removable safety Veins, which are mounted on the drain funnel shower, bath, and sink. It is especially necessary, during the operation of sewage, to prevent the penetration in its issue of dietary fat. To prevent the accumulation of fat, you need to drain it from the sink and clean regularly with a strong stream of hot water. For the same purpose in a local sewer system, it’s recommended for the production of sinks (kitchen) that use a special grease trap.

The grease trap design consists of two pots which are inserted into each other with a certain gap. They meet with each other through the perforations in the inner pot. The grease trap is equipped with a cover (removed fairly easily) to remove the fat that accumulates in the upper compartment of the inner pot. This device is mounted on the release from a kitchen sink (possible and on the kitchen itself) to reduce waste fluid that flows upwardly therein. Proper use of sewage involves periodic cleaning of grease trap from fat.

Clogged pipes

Every owner of a private house, in the course of operation of sewage, has at least once faced the problem of clogged pipes. In this case it is necessary to get rid of clogging through inspection and cleaning by using a rough wire brush that is attached to a steel wire with a diameter ranging from 4mm to 6mm. Also rough cleaning utensils can be made with a piece of rope that has a diameter of6mm-15cm and is 12cm long. To do this in the middle of the cable, firmly attach the folded end of the wire by a binding wire of soft, braided ends untwist (with each side approximately 50mm) and spreading like a fan.

If ice plugs are formed in the sewerage, they can be punched in this way: this portion is fed to a thin rubber hose, through which flows the hot water (the tap water used should be provided through an audit).

When operating the sewage system, the easiest way to clean the taps of sanitary devices is by using rubber device like plunger. To make yourself a very effective plunger, you can use a small children’s rubber ball. For this purpose it is necessary to cut off the ball chet less than 1/3 of the sphere and insert the cut piece into most of the ball (provides rigidity). Wooden handle attached at the center of the ball screw through the washer. In order to clean the clogged portion, it collects water, put to the drain hole and the plunger with a force several times the knob is pressed. Pre-overflow hole bath or sink is necessary to close a wet cloth. In the case where the method of cleaning does not help, it is necessary to disassemble the siphon clogged plumbing devices, properly clean it, reassemble and try again to break through the blockage using a plunger.

In the case where sewage in the operation is detected continuously litter place in this zone should drill a hole 10 mm in diameter (Clean out) that will close a wooden stopper.

Due to the fact that the device is a rather primitive sewage system, many feel that it is easy to create your own, without drawings and calculations. However, the completion of these modifications is extremely difficult. Therefore, it is best to perform on the paper quality design sewer, which will specify the length of pipe diameters, grades, and a list of materials is needed. The diameters of the pipes are caused by sanitary facilities will be connected to any to them. In a pipe which connects a sanitary device to the riser, the diameter cannot be less than the outlet of the device. If several devices are connected to one tube, it should not be less than the greater of the outlets.

When designing a sewer must take into account the sinks, bathtubs, sinks, shower trays, urinals, bidets, dishwashers, and washing machines can have a common connection to the riser. Toilets also need to separately connect to the riser (necessarily below the rest of the equipment). Otherwise, the water to be flushed down the toilet, the waste can flow through the holes in the other sanitary appliances.

Proper design of sewerage is impossible without taking into account the fact that the diameter of the pipe depends on the type and number of connected devices to them sanitary.

These diameters are determined empirically:

  1. for bidets and wash basins – 4cm,
  2. for baths and sinks – 5cm,
  3. to connect multiple downcomers, devices or waste holes without WC – diameter of 7cm,
  4. waste-holes, risers, WC – 10cm.

The design of sewerage systems should take into account the fact that the length of the toilet sewer connections must not be more than 1 meter, and to other devices – 3m. If the connection has a length greater than 3 m and a diameter of less than 7cm, it must have a diameter greater than the calculated one centimeter (for example, instead of 4 cm, make it 5). In the case where the diameter of the connection is 7cm, it should be increased to 10cm only if its length is greater than 5m. These recommendations should act when the height difference between the different endings connections of 1m-3m. If the connection is made with additional ventilation, the pipe diameter does not increase.

In the exercise of designing sewage pipes, you should be aware of the creation of the audit, through which it will be possible to clean the pipe. Those portions of the pipes that connect with the sanitary device with risers, it is necessary to conduct the shortest possible path. They should be attached to struts at an angle of more than 450 degrees between the riser and the toilet, it cannot connect other equipment as drains, which flow from the toilet for the entire cross section of the pipe. It can suck the water through a siphon of this equipment. In the case where the design requires sanitation realize bending of horizontal pipes, it is necessary to perform a bending at an angle of 900. Gravity sewage outside the home should provide biases pipes (1m pipe slope should be from 2% to 15%).

Sewage engineering, materials

In private homes, they mainly use tubes made from polyethylene, polypropylene, polyvinyl chloride species polyester resins which are reinforced with fiberglass. All of the above materials are quite lightweight and corrosion-resistant processes, have a low roughness coefficient. They are much more brittle and rough than ceramic and metal pipes. However, they have a greater strength and resistance to high temperatures.

When they are combined with the compounds of the socket, possibly stretching compensated automatically (approximately 10mm / m). When this is not enough, the system is mounted compensator – straight pipe sections that can move relative to each other.

Biological drain cleaning


The deep biological treatment station is a local wastewater treatment plant for domestic drain cleaning. Stations of different manufacturers can differ constructively, but the principle of operation is always the same – aerobic, with constant access of oxygen, decomposition of incoming wastewaters with the help of “active silt”. Active silt is an active biomass that accumulates during the operation of the station.


The wastes entering the station are averaged over the composition, aerated and, passing alternately through a row of tanks. They are then cleaned by 95-98%. After that, they are removed from the station either by gravity (for example, into a storage or resorption well) or by a pump (into the drainage Ditch, absorbing area, reservoir of fishery value, etc.). The plant’s capacity is determined by the calculation of water consumption of 200 liters (52.8 gals) per person per day. A station designed for 5 permanent residents should have a capacity of 1 cubic meter. Meter per day.


From the existing systems of autonomous sewerage, the stations of deep biological purification have the highest degree of wastewater treatment (up to 98%) and constructive diversity (selected depending on the depth of the sewage pipe, can be completed with a post-treatment filter and ultraviolet disinfectant)


The disadvantages of such equipment can be attributed to their relatively high cost and energy compatibility. Advantages come from the efficiency, the absence of the need to periodically call the sewage machine, and, as a consequence, greater variability in the placement on the site (even indoor installation is possible) and on the tapping of purified water.


If drain cleaning does not enter the station, it continues to operate in an autonomous mode of constant water circulation. A water level sensor is installed in the receiving chamber. At the moment when the airlift pumped water into the aeration tank to the lower level, the sensor sends a signal to the control unit and the solenoid valve. The valve, triggering, directs the flow of air from the compressor to the reverse phase loop. Aeration in the aeration tank is turned off, mixing stops and all active sludge settles to the bottom – the process of denitrification begins.


At a certain distance from the bottom, the recirculation pump starts to pump out excess silt from the aerotank to the stabilizer of the activated sludge. If a mixture of activated sludge and water enters the stabilizer, some silt precipitates in the stabilizer, and the other part, together with water, returns to the receiving chamber. The water level in the receiving chamber begins to rise to the level of the sensor triggering and the transfer of the station back to the direct phase. The aeration (nitrification process) is resumed in the aeration tank, and the recirculation pump stops pumping the active sludge. In this mode of automatic switching, the station will operate until the sewage water enters it.


The diversion of purified water from the plant can be realized according to various schemes. The most common of these are Diversion of purified water by gravity into a resorption well (realized in well permeable soils with low watercut level). Diversion of treated water is done by means of a drainage pump into the reservoir, a drainage ditch, an absorbent pad. Sewage treatment facilities, for example, are used at car washes, gas stations, industrial plants, or construction sites. If the purification system is designed to purify the water from oil products, then pressure flotation is used in combination with fine filters.
