Outside Walls

The best form of septic tank – a round. The thickness of the walls should be at least 25 cm Place entrance to septic pipe which flowed from the house of fecal water, should be located at 5 cm higher than the pipe through which water flows from septic tanks into the drainage system. Wastewater enters the septic tank and leaves the tee through a 100 mm diameter, which establish the electrical and outlet pipes. The upper ends of the tees are still open, and above them make clean – tubes of the same section, and so that the gap between the tee and cleaning up at least 5 cm from the lower ends of the tees attached to them pipes must be of such length that they were 40 cm below current water level in the septic tank. Septic tanks are ventilated through an underground filtration riser domestic sewage at home, which should be displayed above the roof. The filter pit. The filter wells make good use of sandy and sandy loam soils with a quantity of waste water up to 1 m3 per day. Filter wells, as wells and septic tanks, perform reinforced concrete rings, bricks, concrete, rubble stone.

Filter size rectangular wells should be 2.8 * 2 m, depth 2.5 m, if a well-round, then at the same depth, its diameter should be 1.5-2 m wide filter bottom well satisfied with a height of 0.5 – 1 m of gravel, crushed stone , slag, etc. The walls of the filter inside the well should be plastered with cement mortar. In exterior walls and foundation to get well and sprinkled from the same materials used for the filter. Sump. Cesspool do with not less than 0.5 m3 per person. The average of the dimensions: length 2.5-3 m, width – 0.8 – 1 m, depth – 1.5 m. The walls of the sump is made of brick, stone or concrete, then plaster with cement mortar, steel, and is sometimes covered a layer of bitumen.

If manufacture of wood walls used, they should be solid, well-covered, double prokonopachennymi and bitumen. The walls are insulated on the outside layer of fat clay 25-30 cm, carefully compacting it. The bottom of the sump to make bias toward the hatch. Then at the bottom put a layer of fat clay 25-30 cm thick, and the top plank boards or concreted. Overlapping holes could be made of wooden boards, covered with roofing material, but better and more reliable to make it out of concrete, As we told above. In the overlapping arrange hatch 0.7 x0 7 m. The overlap is also an insulating layer of clay 30 cm thick and covered with earth on top. Cleanout opening should be two tightly closing lids, one of which done over the overlap, the second – at ground level. Cleaned the sump, depending on its content. Installation of sewerage systems in private homes and apartments almost identical, except that in the flat all sewers connected to the common sewers, and in a private home – with the individual.
