How to clean a storm drain

An important element of landscaping backyard or suburban area is considered storm sewer. It collects and diverts rainwater and melt water, which can cause serious damage to buildings and all areas in General.

Drainage is a relatively simple structure that should be maintained in a healthy state. Indeed, from time to time in the sewer pipes accumulates debris and traffic jams that impede the normal functioning of the system. How to clean, not to hurt? We will investigate.





Depending on the location of the elements there are two main types of stormwater: open and closed. In the first case the basis for the design be covered with gratings a tray of small depth, United into a common system. They are placed under the slope to the drains running in the right direction. Water is drained into a holding tank, a ditch or a septic tank. Closed stormwater drainage much more difficult. They represent the underground system of sewer pipes, the discharge from the site the water collected in gutters and inlets. In practice, there are mixed storm sewers, consisting of closed and open type.

Regardless of the kind of system they need to be regularly cleared of blockages. The main enemy of the storm sewer become grains of sand and soil particles, which brings the water stream in the pipe. If the system has a properly large debris to get into it simply can not, however, the mud comes here unhindered. She settles and accumulates, which becomes a cause of clogging. In the period of heavy rains and melting snow this process is particularly fast, which requires immediate cleaning system. Depending on the type of stormwater drainage cleaning procedure will have some differences.





Easier to clean open design. You should start with the roof of the house. All the gutters carefully inspected and thoroughly cleaned. This does not require any special equipment, just basic tools. Also thoroughly cleaned and funnels which direct the wastewater drainpipe. The latter can be cleaned using water. For this purpose, the pipe is routed a garden hose. Laid on the ground the trays also should be cleaned. They remove the protective grilles, remove the clog and wash the system with clean water.

Closed or mixed sewage system to clean more difficult. For exemption laid underground pipes from dirt used hydrodynamic method. Tube of mud and sand are destroyed by applying high pressure jet of water. This service provides specialised companies, but you can do on their own. If the pipe diameter of the stormwater drainage does not exceed 20 cm, for washing the system, you can use a homemade wash. For example, a standard Karcher issuing water under pressure at 140 bar, to cope with flushing a closed system.





To cleaning was the most effective, the water is fed alternately: first, in the course of the natural current, then towards. Not giving in to the pressure of the water tube you can try to break using conventional plumbing rope that goes down into the pipe. To clean closed system with a pipe diameter greater than 25 cm, use only professional methods. These include hydrodynamic already described, when the sewage is washed with water, is fed under high pressure from nozzles of various configurations. The professionals in such cases the use of special flushing hydrodynamic machine or channel-washing complex.

Can be used and mechanical cleaning of stormwater drainage – effective, but very time-consuming method. It eliminates serious clogging, which could not be addressed in other ways. So you can remove even the roots of trees or large stones. For professional mechanical cleaning using special equipment. It can be hand-held machines equipped with spirals or fans, or more powerful hardware drum or sectional type.

Another method of cleaning water drain heat. It is most often used in combination with hydrodynamic. Its essence is that for cleaning pipes water is used, which temperature reaches 110 degrees Celsius. The heated liquid easily dissolves all suspension and fat layers covering the inner walls of the parts, then dirt can be washed away with water. Thermal cleaning of stormwater performed only by specialists, because we have to work with boiling water and steam.





Method of chemical cleaning is used, as a rule, after the application of hydrodynamic or mechanical drain cleaning equipment. It allows you to effectively remove deposited on the pipe wall deposits formed from mineral oil, additives, greases and the like substances which is very poorly cleaned with water. In such cases, in pumped stormwater drainage a chemical reagent, solvent contamination. It is important to know that for the plots on which there are houses and cottages, used only biochemical drugs, because they cause minimal harm to the environment.

Cleaning of storm sewer – a mandatory event in order to avoid failure of the system should be conducted regularly. When choosing a treatment method it is necessary to consider design features and its location. For livevox, located in residential areas, usually of the hydrodynamic or mechanical method. In systems that are close to industrial enterprises, with the rain and melt water enter waste oil, oil and similar contamination. In this case, can not do without heat or chemical cleaning. published
