Septic systems are composed of a number of channels by which household wastewater is disposed of. The most important part of any septic system is the septic tank. Septic system design is primarily a series of tanks that can hold somewhere between 500 and 2000 gallons. These tanks are connected by pipes, which are in turn connected to an inlet wastewater pipe on one end and a septic drain field on the other. The connections between the pipes are most often made by a T-type pipe. Each tank usually has two chambers, each with a manhole cover and separated by a wall that has openings on the roof and floor of the tank.
The household wastewater enters the first chamber of the first tank; at this point, the solids settle to the bottom and the scum floats to the top. The solids are settled and digested, which lessens the content of the tank. The remaining liquid flows through the dividing wall and into the second chamber. Here, further settlement takes place so that the excess liquid becomes nearly clear and empties into the drainage field, also known as the leech field. The remaining impurities of the water are then broken down into the soil and taken into the roots of surrounding plant life.
There is often a piping system that is installed in a stone trench that allows the water to be evenly distributed throughout the field. The network will contain multiple holes for drainage. The size of the drainage field will depend on the overall size of the septic tank system. Septic system price also varies based on the overall size of the system, so be sure to keep this in mind when you are getting quotes.
Septic system maintenance is extremely important to ensure your system remains in proper working condition. There are plenty of products that can be used to break down the contents of a septic tank. These are poured down the toilet or drain.
