Understanding Septic Tank Installation For Homeowners New To Septic Systems

Posted on

When managing wastewater in a residential setting, septic tank installation plays an essential role, and understanding how the system works can be helpful to anyone that has never used a septic system for their home. If you're a homeowner considering replacing or installing a new septic system, it's essential to understand the process involved before the installation starts. 

Determining Your Needs

Before starting the septic tank installation process, it's essential to evaluate your home's requirements. Consider things like household size, water usage, and any local regulations that can play a role in the installation.

These elements often determine the size and type of septic tank suitable for your property. Consulting a professional septic system installer or a local health department can provide valuable insights into the appropriate system for your needs.

Permits and Approvals

Septic tank installation requires compliance with local regulations and obtaining the necessary permits. Regulations vary across jurisdictions, and it's crucial to adhere to them to ensure the safety and functionality of your septic system. 

Before starting any septic tank installation, it is crucial to do some research to ensure you can have a septic system on your property. Reach out to the local code enforcement office or relevant authorities to obtain the required permits and approvals before starting your installation. If you are unsure who to call, your septic contractor can advise you.

Site Preparation and Excavation

The installation process begins with site preparation and excavation. A professional septic system installer will assess the terrain, soil conditions, and water table level to determine the ideal location for the septic tank and drainfield. 

The excavation process involves digging trenching for the inlet and outlet pipes and digging a hole for the septic tank to sit in. Proper placement and careful consideration of the surrounding environment are crucial to avoid potential issues in the future.

Septic Tank Installation

Once the site work is complete, the septic tank installation can begin. The septic tank, typically made of fiberglass, concrete, or plastic, is carefully placed in the excavated hole. 

The tank should be positioned according to local regulations and manufacturer guidelines. The inlet and outlet pipes are connected, ensuring proper wastewater flow into and out of the tank. 

The tank is then carefully backfilled with soil, ensuring it is secure and level.

Drainfield Installation and System CompletionAfter the septic tank installation, the drainfield, sometimes called the leach field, is constructed. The drainfield allows the treated wastewater to leach back into the soil. 

It consists of a series of perforated pipes buried in gravel-filled trenches. The pipes evenly distribute the effluent, allowing it to naturally filter through the soil. 

The drainfield placement is crucial and must be in an area with suitable soil conditions to ensure effective treatment.
