The Basics of Septic Tanks
A septic tank is a self-contained unit that receives and stores sewage from a building. It is typically used in rural areas where there is no centralised sewer system. The septic tank breaks down the sewage into effluent and sludge, which is then discharged into a leach field or drain field. The size of septic tank you need will depend on the number of bedrooms in your house and the soil type in your leach field.
What is a septic tank?
A septic tank is a watertight chamber, usually made of concrete, fiberglass, or plastic, in which sewage from a home or business is collected and stored until it decomposes through bacterial action. The effluent from the septic tank flows out through a pipe into a drain field or leach field, where it percolates into the soil.
Septic tanks come in a variety of sizes to accommodate the amount of sewage generated by the home or business they serve. A typical residential septic tank ranges in size from 750 to 1,500 gallons (2,839 to 5,678 liters). Commercial septic tanks can be much larger.
What are the different types of septic tanks?
There are several different types of septic tanks on the market, each with their own advantages and disadvantages. The most common type of septic tank is the concrete septic tank. Concrete septic tanks are typically the most expensive option, but they are also the most durable and require the least amount of maintenance. Fiberglass septic tanks are another popular option because they are much lighter than concrete tanks and therefore easier to install. However, fiberglass tanks are not as durable as concrete tanks and may require more frequent maintenance. Plastic septic tanks are the least expensive option, but they are also the least durable and may need to be replaced more frequently than other types of tanks.
Determining the Size of Your Septic Tank
Before you decide on the size of your septic tank, you need to take a few things into consideration. The first thing you need to think about is the amount of waste that your household produces on a daily basis. You also need to think about the future and how your waste production might change. Once you have a good estimate of your daily waste production, you can start to look at septic tanks of different sizes.
How many people will be using the septic tank?
The size of your septic tank is determined by the number of people who will be using it. The average home uses a 1,000 gallon tank, but if you have a larger family or anticipate more usage, you may need a larger tank.
What is the average daily water usage?
To determine the size of your septic tank, you’ll need to know your household’s average daily water usage. You can typically find this information on your water bill. Once you have that number, multiply it by 0.5 to get a rough estimate of the size of septic tank you’ll need.
What are the local soil conditions?
The first step is to have your soil tested. You will want to know the percolation (or infiltration) rate of your soils. This is a measure of how fast water flows through the soil. The test involves putting a hole in the ground, filling it with water, and measuring how long it takes for the water to seep into the soil.
This test must be conducted by a licensed professional, and you will need to have at least 3-5 acres of land that can be used for the absorption field. The test results will be used to determine the size of your septic tank.
Other Considerations
In addition to the size of your household, you need to take into account the following when deciding on septic tank size:
What type of wastewater will be generated?
The type of wastewater generated by a home or business will have an impact on the size of septic tank required. For example, residences that have a garbage disposal unit will generate more wastewater than those that do not. Businesses that generate large volumes of wastewater, such as restaurants, will also require larger septic tanks.
What are the local climate conditions?
Climate can play a significant role in how often your septic tank will need to be pumped. In areas with high amounts of rainfall, the ground will absorb less water and your leach field will not work as effectively. As a result, you may need to pump your tank more frequently. Conversely, in arid climates where rain is scarce, the ground will absorb more water and you may be able to go longer between pumps.
What is the available space for the septic tank?
There are a few other important considerations when choosing the size of septic tank that is right for your needs, including the available space for installation and the required capacity for your home or business.
The available space for installation is an important factor to consider, as you will need to have enough room to accommodate the septic tank. You will also need to consider the required capacity for your home or business. The required capacity is determined by a number of factors, including the number of bedrooms in your home or business, the number of occupants, and the expected water usage.
