They are essential for maintaining proper sanitation and preventing environmental contamination.

Before you begin the septic tank installation process, ensure you have all the necessary tools and materials. In short, make sure you have the necessary septic tank installation requirements before starting the process to prevent any faults.

  • A leveler tool.

  • Plumbing wrenches and connectors.

Safety Measures to Take Before Septic Tank Is Installed

What Size Septic Tank Do You Need?

What Size Septic Tank Do You Need?

The size of the septic tank you need depends on several factors, including the number of people living in your household and the soil type in your area. 

Generally, a standard tank size for a household of 4-6 people is around 1,000 gallons. However, if you have a larger household or heavy water usage, you may need a larger tank.

What Are The Different Types Of Septic Tank?

What Are The Different Types Of Septic Tank?

There are several types of septic tanks available. The most common types include concrete, fiberglass, and plastic tanks. 

Concrete septic tanks are durable and heavy, making them less likely to float or shift but more challenging to install. Fiberglass and plastic tanks are lighter and easier to install, with resistance to corrosion and cracking. There are also advanced systems with aerobic treatment units that use oxygen to break down waste more efficiently, ideal for sites with poor soil conditions. 

Additionally, some tanks are designed to be low-profile or have special shapes to accommodate shallow or difficult installation sites. Each type has its own advantages and disadvantages, so it is important to consult with a professional to determine which type is best for your specific needs.

Installing a septic tank is a complex process that requires careful planning and execution to ensure proper functionality and compliance with local regulations. 

Here are the general steps involved in the installation of a septic tank, emphasizing the importance of professional involvement:

▪️ Obtain Necessary Permits

Before starting, check with your local health department or building regulatory office to obtain any necessary permits and understand the regulations regarding septic systems in your area.

▪️ Site Evaluation 

Have a professional conduct a soil test (a percolation test) to determine the soil's absorption capacity. This will help in deciding the size and type of septic tank and drainage field needed.

▪️ Design the System 

Based on the evaluation, design the septic system. This includes determining the tank's size, type, and the layout of the drain field. A professional septic tank installation service should be involved in this step to ensure the design meets local codes and environmental regulations.

▪️ Choose the Location 

Select a suitable location for your septic tank and drain field, keeping in mind local regulations regarding distance from the home, property lines, water sources, and wells.

▪️ Excavation 

Excavate the area for the septic tank and the drain field according to the system's design. Ensure the excavation is done accurately to prevent future issues.

▪️ Install the Tank 

Place the septic tank into the excavated area. For concrete tanks, a crane might be needed due to their weight. Ensure the tank is level and secure.

▪️ Connect to the Drainage Field 

Install the piping from the septic tank to the drainage field. The layout and depth should follow the design specifications to ensure efficient waste treatment and dispersal.

▪️ Backfill 

Carefully backfill around the tank and pipes, avoiding damage. Compaction should be done cautiously to prevent settling or damage to the tank and piping.

▪️ Final Inspection and Covering 

Have a final inspection done by a professional or local inspector to ensure everything complies with the regulations and is correctly installed. After approval, cover the tank and drain field area with soil.

▪️ Contact a Professional Septic Tank Installation Company

It is highly recommended to engage a professional septic tank installation company at the outset. They have the expertise, experience, and equipment to ensure that the septic system is installed correctly, efficiently, and in compliance with all local health and safety regulations.

Maintenance Tips for Septic Tank Effective Functioning and Longevity 

Maintenance Tips for Septic Tank Effective Functioning and Longevity 

▪️ Septic tanks need to be pumped every 3-5 years, depending on the size of the tank and the number of occupants in the household. This helps prevent buildup and maintains proper functioning.

▪️ Excessive water usage can put a strain on your septic system and lead to potential issues. Be mindful of your water usage, fix any leaks, and consider installing low-flow fixtures to reduce water consumption.

▪️ Only flush human waste and toilet paper down your toilets. Avoid flushing items such as baby wipes, feminine hygiene products, and grease as they can clog your septic system.

▪️ Harsh chemicals can kill the beneficial bacteria in your septic tank that help break down waste. Instead, opt for natural or enzymatic cleaners to keep your system running smoothly.
