Septic Tank FAQs: Your Questions Answered

Many never think about what happens to the dirty water they use daily. When we flush toilets and wash dishes, the wastewater goes to an underground system called a septic tank.  

Let’s get to know the mechanism of a septic tank and answer other frequently asked questions about the underground wastewater chamber. 

How Do Septic Systems Work?

When water is flushed down toilets or drained through the sink, it goes through exit pipes that lead to the septic tank. Septic tanks have airtight seals and are usually made of concrete and buried underground. Some parts of the system are made with fiberglass and polyethylene or plastic. 

The system holds all the wastewater while allowing solid matter to settle down at the bottom of the tank to form a sludge. Oil and grease floats on top of the water as scum. Water is then drained out while sludge and scum remain. 

What Is the Ideal Size of a Septic Tank?

Septic tanks are where all waste goes, so the larger the household, the bigger the tank. Ideally, a single-family home should have a septic tank with a capacity of 750 to 1,000 gallons. According to the rule-of-thumb calculation, multi-family properties, such as duplexes or triplexes, will have a standard 1,000-gallon base capacity and an additional 250 gallons per bedroom. For example, a duplex with two bedrooms each should have at least a 1,500-gallon septic tank. 

Commercial establishments obviously need larger-capacity septic tanks based on foot traffic. Small businesses should have a minimum 2,500-gallon capacity, while larger ones should have much more. 

These figures are the recommended sizes, and septic systems must follow strict local laws and regulations. Local governments have their own standards based on topography and underground soil type. 

What Is Septic Tank Made Of?

The exterior of the septic tank is made of concrete to ensure it won’t leak and that it can withstand extreme weather changes and other elements. The interior must be watertight so that wastewater is not released into the environment. 

Some septic tank parts are made of fiberglass and fiber-reinforced plastic. Metals are no longer allowed to be part of septic tanks because of their propensity to rust. 

How Do You Take Care of a Septic Tank?

Taking care of septic systems starts at home. Use your water efficiently, and don’t put unnecessary solids into the sink or toilet. 

Here are some helpful tips:

• Don’t put chemicals into the septic system
• Don’t park on the drain field
• Keep the septic system closed
• Get your septic tank pumped regularly

How Often Should You Get Your Septic Tank Pumped?

According to the U.S. Environmental Protection Agency, house septic tanks must be inspected by professionals and experts every three years. Depending on usage, pumping should be done at least every three to five years. 

Professionals will determine if your septic tank needs pumping by looking at the following:

• Size of the septic tank
• Household size
• Amount of wastewater
• Amount of solids in the wastewater

What Should and Shouldn’t Go Down the Drains?

Proper waste disposal is crucial for the health of a septic system. Avoid flushing non-biodegradable items, grease, and chemicals down the drains. Instead, focus on disposing of biodegradable waste and using septic-safe toilet paper. Being mindful of what enters the system can prevent clogs and ensure smooth operation.

What Are the Signs That My Septic Tank Needs Replacement?

Signs of a failing septic system include unpleasant odors, persistent drainage issues, and visible signs of system failure. If you notice any of these symptoms, it’s essential to consult a professional for a thorough assessment. Age is also a factor, and septic tanks over 20 years old may be nearing the end of their functional life.

Can I Landscape Over My Septic System?

Landscaping over a septic system is possible, but it requires careful planning. Avoid planting deep-rooted trees or shrubs near the drain field, as their roots can damage the system. Grass and shallow-rooted plants are generally safe choices. Consult with a professional before undertaking any landscaping projects around your septic tank.
