A Comprehensive Guide to Septic Tank Installation

Septic tanks are an underground system used to treat and dispose of wastewater from homes that are not connected to a municipal sewer system. If you are building a new home or need to replace an existing septic system, there are several factors to consider when installing a septic tank. In this comprehensive guide, we will go through the steps necessary for septic tank installation.

Step 1: Determine the appropriate system size

The size of the septic system will be determined by the number of people who will be using it and the size of the home. Septic tanks are sized based on the number of bedrooms or the amount of water usage in a home. It is recommended that a septic tank be pumped every three to five years to prevent overflow and maintain optimal performance.

Step 2: Obtain required permits

Before beginning the installation process, it is essential to obtain all the necessary permits from the local health department. This process includes soil testing, legal certifications, and construction permits. The permits ensure that the septic system is safe and up to local codes and regulations.

Step 3: Choose the right location

The best location for a septic system installation is on well-drained soil, away from water sources, wells, and within the recommended distance from the house depending on your area’s regulations. Planting trees or plants on the surface of the septic system can help to improve soil absorption and provide good air circulation.

Step 4: Excavate and install the septic tank

After obtaining all the necessary permits and choosing a suitable location, it is time for excavation. Excavation involves digging a hole about two to three times the size of the septic tank. Once the hole is prepared, the septic tank can be lowered into it. The septic tank should be level with the soil surface and should have proper support to prevent settling or cracking.

Step 5: Install the inlet and outlet pipes

The inlet and outlet pipes are the primary components of the septic system. The inlet pipe carries wastewater from the home’s drains to the septic tank. The outlet pipe carries the treated wastewater to the drain field, where the wastewater is treated and absorbed into the soil.

Step 6: Install the drain field

The drain field is where the wastewater is treated and disposed of. The drain field is made up of a series of perforated pipes that are installed on top of a bed of gravel. The pipes allow treated wastewater to seep into the soil and be filtered naturally. The drain field should be properly sized, located, and constructed to ensure optimal performance.

Step 7: Connect to the plumbing and electrical systems

Once the drain field and septic tank are installed, it is time to connect them to the home’s plumbing and electrical systems. Make sure to check the connections for leaks and test the system to ensure that it is functioning correctly.

Step 8: Backfill and cover the septic tank

Once the septic tank and drain field are installed and connected, the soil can be backfilled around them. This should be done gradually and evenly to avoid damage to the systems. The backfilled soil should be soft and free of debris. The effluent filter should be inserted after the tank is backfilled using a vacuum truck.

Step 9: Maintain the septic system

Routine maintenance is crucial to ensuring optimal performance and longevity of the septic system. It is recommended that the system be inspected every three to five years and pumped as needed. You can also practice water conservation by fixing leaks and using low-water-use appliances to reduce the strain on the septic system.
