Septic Tank Installation

What Is a Septic Tank?

Septic tanks are collection or storage tanks used to collect and treat drainage or wastewater in domestic properties. Septic tank installation contractors install the tank mainly in properties not linked to public sewers, which is why you will find them mainly in rural areas. The meaning of septic is “infected with microorganisms”, i.e. the tank has certain bacteria which work to decompose organic waste. We provide various types of septic tanks in different capacities to cater to every size of domestic property.

How Does a Septic Tank Work?

Septic tanks employ natural processes for treating the sewage it collects. They usually consist of two chambers or compartments. The drainage system of the property is connected to the septic tank, and when the sewage reaches the tank, the following process takes place:

  1. Wastewater is collected in the first chamber.
  2. The wastewater disintegrates over time.
  3. Solid particles settle down, while oily substances make a layer on top. A layer of clear water forms in between these two layers.
  4. This clarified wastewater enters the other chamber and exits into the seepage field, also known as the septic drain field.
  5. The remaining solids and scum in the septic tank are decomposed over time by bacteria. The remaining waste has to be removed periodically.

What Tank Size Do I Need?

Before going for septic system installation, you need to know which tank size suits you. The tank size should reflect your water usage and depends significantly on the property size. Septic systems are available in a variety of capacities. Remember that all wastewater from your home will collect in the tank; therefore, a large capacity tank should be preferred. As a thumb rule, a property with 2 to 3 bedrooms should have a 1000-gallon capacity tank. Some experts suggest adding 250 gallons for every bedroom above 3. Other fixtures such as larger than conventional bathtubs may also require a larger capacity septic tank. If you need more clarification about your required capacity, our professionals can help you estimate the right septic tank size for your property and usage.

Location of a Septic Tank

The best locations for septic tank installation are underground or on ground level. Most require a depth of at least 8 to 10 feet, while some advanced tanks can also be placed above the ground. Installing your septic tank on or below the surface can help prevent seepage and flooding. Above-ground installation is not preferred for permanent installation and cannot support very high capacities.

Various factors have to be considered when installing underground, including soil quality, any underground installation, or structures such as piping or electric cables. Underground installation also allows for larger capacities and safer storage. At Fast Drains, we provide both underground and above-ground installations. Regardless of which type of septic tank and installation you want, you can rely on our experts.

Are There Different Types of Septic Tanks?

Septic tanks are usually constructed from four materials: concrete, steel, plastic, and fiberglass. Precast concrete septic tanks are available in a variety of sizes. They are very durable and highly resilient. They come in a single-chamber variety or all-in-one systems. They are highly suitable for installation near water tables as they have high specific gravity and resist buoyant forces. They have a long life and do not require a lot of maintenance.

Steel tanks may have good resistance to water tables, but they are usually not recommended as they can corrode quickly and collapse easily.

Poly septic or plastic septic tank is much lighter than concrete and steel tanks. They are also highly resistant to corrosion and chemicals. They do require anchoring when being installed near a water table.

Fiberglass shares the same properties as plastic but is lighter, making it more vulnerable to water tables. Expect top-quality septic tanks when you contact us for installation. We will provide you with what is best for you and guide you to keep your septic tanks safe.

Septic Tank Drainage

The wastewater from the septic tank has to be drained somewhere, these spaces are known as leach fields or septic drain fields. The septic tank, drain field, and piping make up a septic drainage system. The leach field is usually made up of a series of trenches containing porous materials and perforated pipes. These are covered by soil to prevent any contamination or accidents. The septic drain field can be designed in several ways, and the design should match the system used. At fast drains, we do everything ourselves. Our engineers will thoroughly inspect your site before constructing a drain field for your septic tank.

Septic Tank Repair and Replacement

Septic tanks are usually long-lasting, depending on their material of construction and usage. Carrying out periodic septic system inspections is still a good idea and can prevent many problems. Our expert engineers and technicians can provide you with an annual septic system inspection to check if everything is working as it should. We also offer emergency repairs and complete replacement of septic tanks.

Benefits of Septic Tank Installation

  • If you are not connected to the main sewers, a septic tank can help you manage domestic waste.
  • Septic tanks are nature friendly. They use natural methods of treating waste. The organic waste, in turn, enriches the earth. The drain water is free from contaminants. All these factors make septic tanks eco-friendly.
  • They are an efficient and low-cost method of waste management.

Areas We Cover


Properties which are connected to the mains do not require septic systems. They are only required for domestic installation in areas without sewers.

This depends on the material of the septic tank. A concrete septic tank can last 10 to 40 years with proper maintenance and timely repairs. Concrete is considered to be more long-lasting than other materials.

Septic tanks are installed underground, and a considerable distance is maintained from your living space. Unless there is a leakage, you will not experience any foul smell.

Some leaked tanks may require replacement depending on their material of construction. Most of the fixtures can, however, be repaired.

Septic tanks should be inspected at least once annually to ensure that everything is working correctly and there are no leakages.

No. You should avoid constructing heavy structures on your septic drain fields and never put any heavy-weighing objects on your septic tanks.

Septic tanks employ naturally existing bacteria to break down waste, and no chemicals are used in the process. The drain fields do not contain harmful elements, and the drain water makes the land fertile.

This depends on the system you choose and the capacity you require for your home.
