Understanding Septic Tank Functionality and Waste Disposal

| Gerry Rowe

Septic tanks are an integral part of private sewage systems, responsible for treating the wastewater generated by toilets, showers, baths, sinks, and kitchen appliances. In this blog, we will delve into how septic tanks work and discuss the importance of proper waste disposal.

To begin, septic tanks operate on the principle of separation. They facilitate the settling of solid waste, such as toilet paper and other organic matter, while allowing the liquid wastewater to flow out through a second stage of separation and then into the soil for further treatment. This separation process is crucial for the effective functioning of the system.

One common issue that can disrupt this process is the accumulation of fat, oil, and grease in the septic tank. These substances form a thick layer that floats on top, similar to an iceberg. Most of this layer remains submerged, and only a thin portion is visible above the water's surface. This fatty layer can hinder the separation process and impact the tank's functionality.

To calculate the optimal schedule for emptying your septic tank, certain information is necessary. First, the number of bedrooms in your house determines the size of the sewage system. If there is a change of ownership or an increase in family size, it is essential to consider these factors.

Additionally, understanding the current usage and the size of the septic tank is crucial for scheduling emptying. Consulting a tanker driver, or installation engineer or conducting a survey can provide accurate information for maintenance planning.

It is worth noting that the septic tank is just one part of the system. The other crucial component is the drainage field. This is where the final treatment takes place.
