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.
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 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: Final Thoughts
In conclusion, cesspool collapse can be caused by a variety of factors including tree root infestation, freezing temperatures, above ground pressure, poor backfill support, aging cesspool.
