Introduction

A cesspool is used to store sewage. While they are a commonly used method of sewage treatment, they are not without their problems. One of the most significant issues that can arise with a cesspool is its collapse. In this article, we will explore the various causes of cesspool collapse and what can be done to prevent it.

What Causes A Cesspool To Collapse: Tree Root Infestation

One of the most common causes of cesspool collapse is tree root infestation. Trees and other plants have a natural tendency to seek out moisture, and the sewage in a cesspool provides an ideal source of water for them. As the roots of these plants grow, they can infiltrate the walls and floor of the cesspool, causing it to crack and eventually collapse. To prevent this from happening, it is important to keep trees and other plants at a safe distance from the cesspool.

Freezing Temperatures

What Causes A Cesspool To Collapse

Another cause of cesspool collapse is freezing temperatures. When the temperature drops during winter, the wastewater in the cesspool can freeze and expand, putting a lot of pressure on the walls and floor of the cesspool. This can lead to cracks and collapse. To prevent this from happening, it is important to winterize the cesspool.

Above Ground Pressure

Above ground pressure can also cause a cesspool to collapse. This pressure can come from a variety of sources, such as driving or walking over the cesspool. The weight of these activities can cause the walls of the cesspool to cave in and collapse. To prevent this from happening, it is important to make sure that the cesspool is located in an area where there is little or no above ground pressure.

Poor Backfill Support

Poor backfill support can also cause a cesspool to collapse. When a cesspool is installed, it is surrounded by soil to help support it. If this soil is not compacted properly, it can cause the cesspool to sink and collapse. To prevent this from happening, it is important to make sure that the soil is compacted properly in order to support the cesspool.

Aging Cesspools

Aging cesspools can also collapse. Cesspools are not designed to last forever, and over time, the walls and floor can become weak and eventually collapse. To prevent this from happening, it is important to have the cesspool inspected regularly to detect any signs of weakness before it collapses.

What Causes A Cesspool To Collapse: Corrosion & Rust

Concrete cesspools are also susceptible to collapse due to corrosion. Concrete is a porous material and over time, it can absorb moisture, becomes weak and corrodes. On the other hand, steel cesspools are susceptible to collapse due to rusting. Steel is a metal that can rust over time, and this can weaken the walls and floor of the cesspool and cause it to collapse. To prevent this from happening, it is important to make sure that the steel is coated with a rust-inhibiting paint.

How deep is a cesspool

The depth of a cesspool can vary depending on a number of factors, such as the type of soil, the water table, and local regulations. In general, a cesspool is typically 6-12 feet deep.

What Causes A Cesspool To Collapse: FAQs

If you suspect that your cesspool is backed up, there are several signs to look out for. Firstly, check if your cesspool is overflowing or if there are any unpleasant odors around the area. Gurgling sounds coming from your toilet or drains can also indicate a blockage. Slow drains throughout your home, including sinks and showers, are another sign of a possible backup.

Additionally, if you notice that your lawn is unusually lush and green, it could be a result of the excess nutrients from a backed-up cesspool. Lastly, keep an eye out for pooling or standing water near the location of your cesspool. If you observe any of these signs, it is advisable to contact a professional plumber or septic system specialist to assess the situation and perform any necessary repairs or maintenance.

The lifespan of a cesspool primarily depends on various factors such as the quality of materials used, frequency of usage, soil conditions, and the type of household waste being disposed of. On average, a well-maintained cesspool can last anywhere between 20 to 40 years. The construction material plays a vital role in determining its longevity. Cesspools made of durable materials like concrete or plastic tend to have a longer lifespan compared to those made of less sturdy materials. Proper maintenance, regular pumping, and avoiding the disposal of harmful substances can significantly extend the life of a cesspool, ensuring its functionality for years to come.

The cost of converting a cesspool to a septic system can vary widely, typically ranging from $5,000 to $30,000. Several factors contribute to this cost variation, including the type of septic system, soil conditions, accessibility, and local labor and material costs. However, the expense of converting is often justified due to regulatory requirements in the USA. Cesspools are considered outdated and environmentally harmful, leading to groundwater contamination and health risks. Consequently, many states and local municipalities have made cesspools illegal, necessitating their conversion to more modern and efficient septic systems. While the initial investment may seem substantial, the long-term benefits of a septic system, such as improved water quality and compliance with regulations, make the conversion a worthwhile investment for homeowners.

Emptying a cesspit requires professional assistance. Firstly, locate the access point or manhole cover. Remove the cover carefully, ensuring safety precautions are followed. Next, contact a licensed cesspit emptying service. They will employ a vacuum tanker to suction out the contents, disposing of it appropriately. Finally, replace the cover securely to prevent any issues. Regular maintenance and emptying are essential to avoid potential overflow or environmental hazards.
