Sewage system of private houses is provided using simple materials. To arrange the drainage system of a private house are simplified'll need: plastic pipe and the material for the device capacity of a septic tank (ceramic bricks, concrete rings or used tires large diameter). The capacity of the septic tank should be done from a biological sewage treatment plant, if the soil is not clay, and the groundwater level more than 2-2. 5 meters. The septic tank will be a filter well, providing partial treatment of waste waters.
In the first stage, the device of the Sewerage system should determine the location of the septic tank, i.e. the tank drains. Here it is necessary to consider the level of water intake, if you in the area well or well with drinking water to prevent spillage of wastewater.
Also should as far as possible to place the septic tank from a residential building, but to consider the possibility of pumping sewage. Putrefactive bacteria in the septic tank – cesspool, with enough volume and low groundwater level, will operate the wastewater system effluent for several years without further purification.
The device of a septic tank involves different options. The easiest way is to use the old car or tractor tires. Septic tank with ceramic bricks should be laid without mortar at the side joints to ensure effluent discharge. Concrete construction when laying on the joints also need to provide filtering into the ground. Cover of the septic tank should provide security while on a cesspool. So the best to do it in concrete with a hole for the hatch. Modern hatches are produced from cast iron, and polimerpeschanaya material.
Next, measure the length of the sewer line. The pipe is better to use a polymer, preferably more durable and to avoid the installation of unnecessary joints to prevent deflection during laying. The diameter of the pipes to optimally choose 110 mm and as close as possible to bring it to the source (sink, washing machine, bath) and already there to make an adapter for a diameter of 50 mm, thereby there will be less blockage.
When laying a long enough sewer lines will require revision elbows, designed for cleaning in case of blockage. It is important to ensure the maximum angle of descent of the pipe, at least 5 degrees. The depth of the drain lines is based on the freezing ground in your latitude, usually not less than one meter.
