  • Damage And Problems In Septic Tank

When sending solid particles into a septic tank with a 1,500-gallon capacity, they will start to accumulate. This particular accumulation is known as sludge. The waste particles that are broken down when bacteria are present in a septic tank can also become sludge when the bacteria do not have the potential to attack this waste and break it down into finer particles.

The main reason as to why this problem arises is when waste particles are not in a state of suspension for long enough. If this occurs, bacteria that are known for breaking down this waste does not have sufficient time to break-down the waste. When sludge accumulates in septic tanks, this will directly affect the capacity of a tank as well as decrease the beneficial bacteria already present.

In many cases, there may be around 400 gallons in sludge that will settle in the bottom part of the tank. This will mean that there will be only 1,100 gallons of water that contains bacteria left to break down the waste particles and waste food. This is why it is extremely important to conduct regular tank-maintenance. If the tank becomes filled up with sludge the delicate balance of the bacteria is usually destroyed. In addition, it is important not to send solid objects that cannot be broken down such as plastic, cat litter, or plastic toys into a septic tank.
