Acquire a permit to install a sewage disposal system. Inquire about the requirements from the relevant offices in your location. For example, citizens in North Dakota require a permit certifying that the tank meets the specifications of the North Dakota State Plumbing Code. Similarly, find out from the local zoning officers and health department the requirements of your sewage system.
Determine the location of the septic tank based on the characteristics of the soil, including its texture and local hydrology. Hire the services of a registered soil classifier to do this. Some health departments allow pre-location tests to satisfy the suitability of the soil. The soil in the drainfield facilitates the absorption process after the effluent seeps from the septic tank. Aerobic bacteria break down the effluent into harmless products like carbon dioxide and methane.
Select a quality tank to install in your desired location. Hire qualified professionals to install your septic tank system. A shallow septic tank installation is most suitable as it facilitates the treatment process. A deep septic tank installation is advisable in an area lacking a high water table. The tank should be at least 10 meters away from your home.
Ensure the installation is properly done. Consult the health department to examine your tank. This is important because the septic tank is where the effluent separates into the floating scum, the middle layer of liquid materials and solids, which settle at the bottom as sludge.
Inquire about the maintenance requirements of your sewage system from the health department. Avoid passing certain chemicals like paints, kerosene, plastics, tampons and oils through your system as they can damage your tank or cause blockages in the system.
Pump your septic tank at least once every three years to remove accumulated substances like sludge and grease. Pumping also prevents your system from overflowing.
