So how many of us have Septic Tanks. 

Based on data from the U.S. Census Bureau, around 2010, approximately 26 million residences in the United States relied on septic systems for waste management. This accounts for nearly 20% of all households in the nation. The prevalence of septic systems differs significantly across states, with the highest usage observed in Vermont (55%), Maine (50%), New Hampshire (45%), and Rhode Island (40%). Conversely, the states with the lowest adoption rates include California (10%), Hawaii (11%), and New York (12%).

In people numbers now over 60 million Americans rely on septic systems to handle their household waste, and about one-third of new developments incorporate these systems. By nature, septic systems are relatively straightforward. All drains in a home come together into a single pipe that connects to the buried septic tank outside. As water from your toilet, shower, basins, and laundry machine departs your residence, it merges together. Once it reaches the septic tank, the waste starts to separate.

The heaviest particulate matter in the waste, known as sludge, settles at the bottom. Meanwhile, fats, oils, and proteins form the floating scum layer at the top. Sandwiched between these layers is the relatively clear liquid layer called effluent or gray water. Collectively, these components make up what we call septage.

Septic setups are engineered to ensure that solely the outflow gets released from the container into the drainage area, commonly referred to as the leach field.. This consists of a set of pipes with holes drilled into them, which release the effluent below ground but above the water table. The effluent is degraded enough to be effectively filtered by good soil. The remaining organic material in the effluent acts as a fertilizer, which is why the drain field usually has the healthiest section of the yard above it.

Although their structure is straightforward, it is essential for homeowners to keep an eye on their septic systems to avert potential issues. Generally, once a problem becomes noticeable, it's too late for an easy solution. Addressing major septic issues can often require thousands of dollars in parts and labor. Fortunately, regular maintenance can help avoid such problems. Keep reading to find out how often you should pump out your septic tank.

Disposing of Septage: From Revolting to Resourceful

In areas with a high number of homes using septic tanks, you'll likely find several local businesses that specialize in removing the scum and sludge accumulating in the tank over time. This is a crucial service; if too much sludge builds up, it can lead to overflow, which is bad news for everyone.

In most cases, commercial septic pumping includes employing a pump truck to extract the accumulated solids, liquid waste, and floating matter from the tank, leaving it empty and set for the next filling cycle. Once the waste is removed, there are limited options for its disposal. Before federal laws restricted septic sludge dumping, waste companies could simply bury it in dumpsites. As these sites were recognized as health hazards, they were outlawed. Many of these sites remain, although numerous are undergoing remediation (cleanup).

Nowadays, federal and state laws dictate the final destination of your septic tank's contents. In some cases, the septic waste is transported to waste treatment plants, added to the mix piped in from municipal sewer systems, or delivered to independent, for-profit companies specializing in septage treatment. Septage may also be disposed of in approved landfills. However, the guidelines governing septage dumping are stringent, and suitable sites can be scarce.

Because of the challenges posed by disposing of your septic tank's contents, septage is often repurposed in another way: as a fertilizer for food crops. Unless there's a "USDA Organic" label on it, it's possible the food on your table was grown using the sludge that was once in your septic tank.

This use of septage can be controversial. Proponents, including many commercial farmers, argue it's a win-win situation since municipalities don't have to worry about waste disposal, and farmers receive inexpensive fertilizer for their crops. 

When used appropriately on agricultural land featuring healthy soil and a shallow water table, the soil should function as a filtering medium, akin to a drainage area in a residential setting. a septic tank. However, the use of biosolids in agriculture is a contentious subject and continues to be scrutinized as a potential health and environmental threat. While some view it as an effective way to recycle waste, others, including scientists and health professionals, believe that using biosolids in agriculture poses risks to both farmland and public health.

There's another, more innovative way to use septage — generating electricity to power homes. It has long been known that methane, a byproduct of sewage breakdown, could be harnessed to generate electricity. While methane is a simple fuel, it can also be broken down and used to produce electricity using fuel cells located on-site at treatment plants. The electricity generated in this process doesn't combust, resulting in little to no pollution.

Septic Tank Cleaning FAQs

How often should a septic tank be pumped?

Septic tanks should be pumped every three to five years and inspected by a professional once every three years.

Can I pump my septic tank myself?

Attempting to pump your septic tank yourself can result in hefty fines. In most neighborhoods and localities, licensed companies are responsible for this task.

Do septic tank additives help?

No, research has shown that chemical and biological additives can actually be harmful to septic systems.

How do I know if my septic tank needs cleaning?

If your drains are blocked and there is an unpleasant odor, it's likely that your septic tank needs cleaning. Even if these signs aren't present, you should consider having your septic tank cleaned if it's been three to five years since the last pumping.

How expensive is it to clean a septic tank?

On average, cleaning a septic tank costs around $375. Pumping out the tank can cost $250 for a 3,000-liter tank and approximately $1,000 for a 5,000-liter tank.

Exploring Different Septic Systems

Various types of septic systems are available to homeowners, each with its own advantages and disadvantages. These systems can be broadly categorized into conventional systems, alternative systems, and aerobic treatment units.

Conventional Systems

Conventional septic systems are the most common and include gravity systems and pressure distribution systems. Gravity systems rely on the natural slope of the land to move effluent from the septic tank to the drain field. Pressure distribution systems use a pump to evenly distribute effluent across the drain field, which can be more efficient and better suited for properties with uneven terrain or shallow soil.

Alternative Systems

Alternative septic systems are designed for properties with specific site limitations, such as high water tables, poor soil quality, or limited space. Examples of alternative systems include mound systems, sand filter systems, and evapotranspiration systems. These systems typically require more advanced technology and maintenance but can be effective solutions for challenging properties.

Aerobic Treatment Units

Aerobic treatment units (ATUs) use oxygen to break down waste more efficiently and rapidly than conventional septic systems. These systems can be especially useful for properties with limited space or poor soil conditions. However, ATUs often require more frequent maintenance and higher energy consumption.
