Septic Tank Age: How to Know your Tank is Ageing

Large green septic tank

Septic tanks are an important part of many UK homes that are not connected to a municipal sewer system, but over time, these systems will need to be renewed. It’s important to be aware of the signs of septic tank age, so you can take action before it becomes a major problem. Remember; it is the tank owners responsibility to ensure it is maintained!

Sinks and Drains are Slower to Drain

When a septic tank becomes full, the excess waste and water has nowhere to go, and it can start to back up into the drainage system, causing sinks and drains to become slow to drain. This is because the excess waste and water is blocking the flow of water through the drain field, making it difficult for water to flow freely through the pipes. 

Additionally, a malfunctioning septic tank can also cause a buildup of sludge and scum in the tank. Over time this will lead to clogs in the drainage system. Sinks and drains will begin to become slow to drain as the sludge and scum will block the flow of water through the pipes.

Foul Odours Coming From Septic Tank

Foul odours coming from your septic tank can be a sign that it is time to replace your system. Septic tanks are designed to hold and treat household waste, but over time, they can become damaged or worn out. This leads to a variety of problems, including the release of unpleasant smells.

One common cause of septic odours is a clogged or overflowing tank. As waste accumulates in the tank, it will become compacted and clog the system’s pipes. Another reason for the stench may be a damaged or leaking tank. If you notice a bad smell coming from your septic tank, it’s important to have it inspected and evaluated by a professional. They can determine if the tank is damaged or worn out and recommend the appropriate course of action. Sometimes the replacement of the tank is the only option.

Spongy Grass or Standing Water Around Tank

Spongy grass or standing water around a septic tank could indicate a problem with the tank’s drainage system or cesspit. This could mean that the tank is full and needs to be emptied or that the drain field is not functioning properly. If the tank is full, the excess waste water can overflow and cause the ground to become saturated, resulting in spongy grass or standing water.

The waste water may not be properly absorbed into the soil and can again cause standing water or spongy grass if the drain field is not functioning properly. In either case, it’s recommended to have a septic professional inspect the tank and drain field to determine the cause of the problem.

Crumbling Concrete, Rust or Ware and Tare

Crumbling concrete, rust, and wear and tear on a septic tank can all indicate that the tank is in need of replacement. Concrete septic tanks can develop cracks and holes over time due to exposure to the elements and ground movement, which can cause the tank to weaken and eventually fail.

Rust on a metal septic tank can indicate corrosion, which can also weaken the tank and lead to failure. Wear and tear on a septic tank can include dents, scratches and other forms of damage which will weaken the structural integrity of the tank, making it more likely to fail. In any of these cases, it is recommended to have a septic professional inspect the tank and determine if replacement is necessary.
