How Do I Know How Big My Septic Tank Is?
If an undersized septic tank’s holding capacity is exceeded, sewage can back up into your home, so it’s critical to calculate the exact size when installing a septic tank. Even the smallest septic tanks must store about 1,000 gallons in most communities.
The necessary capacity grows from there, depending on how many bedrooms, occupants, bathrooms, and fixtures the septic system will handle.
Septic tanks come in a variety of shapes and sizes, and it’s easy to forget or never learn how big yours is. However, knowing the capacity of your septic tank is vital since it impacts how often it should be pumped. There are two ways to accomplish this.
Rely on Current Records
This may be documentation from the original system installer, the last supplier that filled the tank, or the prior owner. You may also get septic system records from your county’s septic permit offices. The position, dimensions, and design of the septic tank can be found in these records, but they are not necessarily correct.
Look about your house for hints as well. The size of the septic tank required is determined by the amount of bedrooms as well as square footage of the property. One may use the table below to estimate the size of your septic tank.

Hire a Septic Maintenance Provider
Although documents and the size of your home can help you estimate the size of septic tank on your land, it’s only a guess. Documents may be incorrect, and a former owner may have installed a tank that is larger or smaller than required.
The only way to be positive about the size of your septic tank is to have it located, opened, and pumped by a septic service provider. He or she will be able to tell you the exact size of the item as well as whether it is in good condition or requires maintenance at that time.
Septic Tank Size Affects Pumping Schedule
What does it matter if you know the size of your septic tank? Because it impacts how frequently it needs to be pumped in order to maintain top performance.
In general, we recommend pumping your septic tank every 3-5 years – the smaller the tank, the more frequently it must be pumped. Tanks that go too long without this maintenance are more likely to become backed up or fail, necessitating costly repairs or replacement.
Step 1: Determine how many people will use your septic system on a regular basis. Most municipalities assume four regular residents in a two-bedroom property, for example. Six people can fit into a three-bedroom home.
Step 2: Calculate how many bathrooms the septic tank will be able to handle. Include the second bathroom in your count if you just have one bathroom now but want to install one later to avoid having to replace your tank.
Step 3: Count how many plumbing fixtures you have in your home. This figure includes all faucets, toilets, showers, dishwashers, laundry washers, and any other septic tank-draining fixture.
Step 4: To ascertain proper septic tank sizing, take your calculations to your local permission office and compare them to your local laws. The guidelines for sizing differ slightly from one place to the next.
Step 5: A tank of at least 1,250 gallons is required in Arizona for a three-bedroom house with two bathrooms and around 20 fixtures. A 2,000-gallon tank is required for a building with 14 residents and three to five baths.
Determine Your Septic Tank Size
Every septic system owner should be aware of the size of their septic tank. What difference does it make if you know how big your tank is? It’s crucial to understand the size of your septic tank so you can figure out how often it has to be pumped to keep it running smoothly.
In comparison to the expense of a new system, the minimal amount of preventative maintenance that septic systems require is quite low. As a result, it’s critical to know when your septic tank will need to be pumped so that you don’t miss a maintenance appointment.
Solids and grease will overflow into your drainfield if you fail to pump your septic tank on a regular basis. If particles build up in the tank to a point where they block and strain the system, a new drainfield may be required.
Find out how big your septic tank is now, before it’s too late.
The minimum septic tank capacity requirements are determined by a number of variables. State, county and/or local rules might dictate permissible sizes as well as tank material and location.
The efficiency of a system is influenced by soil characteristics and area topography, which can affect drain field and septic tank size.
The size of the septic tank depends on whether it’s for domestic or commercial usage; here, we’ll focus on residential use. The size of the required tank might also be affected by the septic tank system that is now in place or that will be erected.
The size of your septic tank may be determined using documents from the time it was installed. These documents may have been kept by the former owner of your home. Another approach to figure out the size of your tank is to speak with the last firm who maintained or pumped it.
You can also obtain these data from your county’s environmental health agency if you can’t reach the former owner or septic firm. These papers may include information such as the location, size, and structure of your system, as well as a map of your system.
Counting the number of bedrooms in your home is another technique to determine the size of your septic tank. The chart below shows the anticipated size of your tank based on the number of bedrooms in your home.
There is, however, only one way to tell for sure how big your tank is. This may be accomplished by having a septic specialist visit your home, identify the tank, open it, and pump it. They can then estimate the size of your tank and tell you how frequently it will need to be pumped.
Hiring a professional can also help you assess whether your tank is in good condition or if it need more maintenance. Septic tanks serve an important part in keeping homes without access to public sewage clean and safe, and there are many different solutions depending on the individual or family’s needs.
While the type of septic tank can be chosen based on personal desire, it is critical that the right size be carefully calculated so that waste can be efficiently broken down.
Homeowners can choose from a few different approaches to assist them assess the septic tank size that is suitable for their home.
Bedroom and Square Footage Calculation
Another of the easiest techniques for homeowners to identify the optimal septic tank size for your house is to base their opinions on the numbers of used bedrooms as well as the floor space of the house.
- One to two bedrooms and under 1,500 square feet: 750-gallon storage tank
- Three bedrooms and a living space of less than 2,500 square feet: 1,000-gallon storage tank
- Four bedrooms and a living space of less than 3,500 square feet: tank capacity increased from 1,200 to 1,250 gallons
- Under 5,500 square feet and five or six bedrooms: 1,500-gallon storage tank
Water Usage Calculation
The most precise way, according to SEPTIC PROFESSIONALS, is to design a septic tank based on initial water demand. The person uses 75 gallons of water each day, but devices like dishwashers as well as washing machines must also be considered. Individuals can look up use details on their utility bills.
- 500 Gallons or Less: 900 Gallon Tank
- 500 to 700 Gallons: 1,200 Gallon Tank
- 700 to 900 Gallons: 1,500 Gallon Tank
- 900 to 1,240 Gallons: 1,900 Gallon Tank
Those who are torn between two tank sizes due to differing estimates should factor in additional costs before making a selection. Higher-capacity tanks will be more expensive upfront, and all tanks will need to be pumped every three to five years. Budget may be the deciding issue in many situations.
