There are as many different methods for septic system installation as there are different types of septic systems. In general, a septic system refers to an on-site system that safely and sanitarily disposes of biological waste. Most septic systems use a holding tank design, which means that human waste is left to decompose in a container. The decomposed waste usually takes the form of water before being released from the container.
According to legal regulations, septic systems usually have to be made out of certain materials. Traditional materials like concrete gradually have been phased out in favor of materials such as plastic. This generally is because plastic is considered to have a longer shelf life while also being easier to relocate if the septic system has to be moved or becomes damaged.
In general, septic systems are installed away from sources of drinking water and at a safe distance away from residential homes or commercial properties. This usually helps to avoid any damage or sanitation problems that may result from waste being preliminarily discharged from the unit. To determine the right location for septic system installation, sometimes a percolation test may be used. This can help determine with more accuracy how the water percolates into the soil, helping identify the best place to install the unit.
Measuring generally is an important part of septic system installation. Proper measurements can determine the size of the hole that needs to be dug to accommodate the unit. Digging the hole may be a difficult task depending on the size of the septic system. Sometimes when the required hole is of a fairly large size, digging equipment is used to help make the job easier.
Usually after the hole has been dug, the septic tank is inserted into the ground. This step generally is followed by connecting the tank to the plumbing system. In most cases, plastic PVC pipes are used to connect the two. An important part of the septic system installation process can be planning the piping system beforehand. This helps determine the most efficient way of laying the pipes and how much piping is needed.
A good method for septic system installation generally takes note of how well the pipes are connected to the septic tank. A bad connection can mean that biological waste will leak out of the piping system before it reaches the septic tank. This can contaminate the soil around the septic tank. One of the methods for testing any potential pipe leakage is to flush the toilet a few times after the tank has been connected to the plumbing system, and observing if there is any leakage.
After the piping system has been verified as functional, the dug-up ground then can be backfilled with soil. Normally the top of the septic tank is not covered with soil. This allows for easier access in the case of plumbing problems.
There are many septic tank dealers and installation services available for those who don't want to install their own septic system. These companies typically can eliminate some of the hard work and stress of septic system installation. Usually these companies employ professional technicians, who have developed their own precise methods based on their experiences in installation.
