Septic tank closely associated with the biological activity of the entire household. That are not easily filled and compressed, it needs the right design. The design and improper maintenance, can make the septic tank is not functioning properly.
Septic tank is a sanitation system that consists of a pipeline from the toilet, liquid manure tanks and solid, air infiltration, and water discharge pipe and air. In order for a septic tank is full and not easily compressible, note the following:
The slope of the pipe. The slope determines whether current waste disposal process. Difference in height toilets and tank water surface dirt, preferably as large as possible. In order to flow smoothly, the slope of the pipe a minimum of 2%, meaning that there is a difference each 100cm height 2cm.
Select the appropriate pipeline. The pipeline should be a PVC pipe. The minimum size is 4 inches. The house has plenty of toilets, you should use a larger diameter pipe. Draw a straight line with no curves, because curves or angles, vulnerable incompressible.
Adjust capacity needs. For homes with a number of residents for up to four people, just made septic tank with a size of 1,5 m x 1, 5m x 2m. Tank deposition and infiltration wells can be made to the size 1mx1mx2m. More and more of the household, the greater the required size.
Tank must be strong and waterproof. Walls, foundation, and cover the main basin must be watertight, so that the waste does not pollute the environment. Tank deposition and infiltration should have a basic form of a mixture of gravel and sand.
