Installation of a septic tank.
If you hire a company to install a septic system, these steps would likely be taken:
Obtaining permits: Before installation begins,the necessary permits required in your area need to be secured. The contractor you hire should do this task. If the contractor fails to do this, you could find yourself having to tear out the tanks and pay hefty fines.
Surveying the field to be used: The plumber or septic contractor will perform topography surveys of the area and complete a blueprint and project plan to ensure that your new septic tank will be positioned properly. Local zoning ordinances may require the septic tank be placed a set distance from structures and/or the property line.
Excavation and site preparation: This includes bringing in sand and gravel for the leach field. Accurate site prep is essential for the system to work properly since the force of gravity provides the necessary flow.
Stubbing out the plumbing: The term "stubbing out" refers to having a building's plumbing in place, but capped at various points awaiting installation of fixtures. So at this stage the plumber installs the drain from the house to the septic tank, ready for connection. The pipe needs to have the correct "fall," or degree of decline over distance to use gravity. If a toilet or sink is installed in the home's basement, a sewage sump pump must be installed and piped into the main drain.
Installing the septic tank: When the plumbing field is ready the septic tank is installed.
Connecting the tank to the plumbing: The piping that runs from the interior plumbing system of the home out to the septic tank will be connected and sealed to prevent leaks. Any drainage pipes that are necessary out to a secondary drainage area to prevent excessive pooling of water will also be connected at this point. The system will be tested to ensure that it operates properly. Once all connections are completed, the septic field will be filled in to hold the tank in place and provide proper operation of the septic system.
