If you own a property with a septic system, accessing and replacing it, if necessary, is an important task. However, many people are unfamiliar with septic systems and their specifications and dimensions.

Different types of septic tanks suit other households and drainage systems. To know what septic system size you need for your household, keep reading for information on the different septic tank sizes.

Consider Your Property’s Size

When considering the size of septic tanks, it is `essential to consider the size of the land on which they will be installed. Larger properties with higher foot traffic typically require a larger septic tank to accommodate the larger effluent produced.

Conversely, a smaller property with lighter foot traffic would require a smaller septic tank. Small tanks come as small as 500 gallons, and larger tanks can hold up to 2,500 gallons or more.

The experts at Tanks for Everything are well-prepared to answer all your questions about septic tank sizes. Whether you’re building a new home or looking to replace an existing tank, they have an array of measures to meet your specific needs.

Number of Bedrooms Your Property Has

The number of bedrooms in the house significantly impacts the size of the septic tank you need. Generally, for properties with up to 3 bedrooms, a septic tank with 1200–1800 liters should be more than adequate.

For properties with four or five bedrooms, a septic tank with a capacity of 1850–2400 liters is suggested. Septic tanks with a total of 3000 liters or more are required for properties with 6 or more bedrooms.

It is crucial to choose the correct size of the septic tank, as if it’s too small, you risk overloading it and emptying it, while if it’s too big, the bacteria will not be able to break down the waste, and the system may fail.

Number of Occupants

The size of the residential septic tank depends on the number of occupants and the people in one home. Generally speaking, a 1500-gallon tank is suitable for a house carrying three occupants or fewer.

A 2000–2500 gallon tank is ideal for four to six occupants, a 2500–3000 gallon tank is suitable for seven to eight occupants, and a 3000-5000 gallon tank is ideal for nine to ten occupants. Larger tanks exist for more than ten occupants.

Ensure the tank is appropriate for the number of occupants because if it is too small, it can become overwhelmed and lead to septic system failure. Likewise, installing a larger tank than is necessary can be a good use of money as it requires more maintenance and can lead to overflowing.

Choose Appropriate Septic Tank Sizes to Meet Your Needs

Different septic tank sizes suit almost any need, from large residential septic tanks to larger ones used in commercial and combined applications. With so many options available, it’s essential to research and chooses the right size for your property and project. As a takeaway, this guide provides the necessary knowledge to find the perfect fit.
