March 20, 2024

At Calcamite, we understand the crucial role septic tanks play in maintaining the health and safety of your environment. For over 50 years, we’ve been leaders in providing effective on-site sanitation solutions across South Africa. However, even the best systems can encounter problems. Recognising the signs of a septic tank problem is key to ensuring the longevity and efficiency of your septic system.

Septic tanks are integral to proper waste management, especially in areas without access to centralised sewer systems. But why do septic tank problems occur? Often, it’s due to a lack of regular maintenance or incorrect usage. Recognising the warning signs of septic tank problems early can save you time and money, and it helps protect our environment.

How Exactly Do Septic Tanks Work?

To understand the signs of a septic tank problem, it’s essential to know how these systems work. A septic tank drainage system is a simple yet effective method for treating household wastewater. In its basic form, a septic system includes a tank and a drainage or soakaway area.

In a typical setup, wastewater flows into the septic tank, which is buried underground. Here, the magic happens. The tank’s design allows for the separation of solids from liquids. Heavier materials, like food particles and human waste, settle at the bottom, forming sludge. Fats, oils, and grease, being lighter, float to the top, creating a layer of scum. This natural process is crucial for the initial treatment of sewage.

The middle layer, or effluent, is relatively clear liquid. This effluent then flows out into a drainage field. Here, further treatment occurs as the effluent percolates through the soil, removing harmful bacteria and nutrients.

At Calcamite, our two-chambered septic tanks are designed for optimal efficiency.

In the first chamber, domestic sewage undergoes natural separation: solids settle to form sludge, while lighter materials like fats rise to create a scum layer. This process is crucial for producing a clearer effluent, and correct tank sizing is essential to ensure effective breakdown over a minimum 24-hour retention period.

The second chamber is specifically designed to extract the clearest, most solid-free effluent from the primary chamber, significantly reducing the risk of septic tank seepage problems.

Our soakaway drainage system, an integral part of wastewater management, allows treated effluent to percolate into the soil, further purifying it before it reaches groundwater or surface waters. This system’s effectiveness hinges on proper sizing and suitable soil conditions. We offer both conventional soakaway systems and advanced Infiltration Chambers, which promote the formation of a bio-mat of bacteria, enhancing the treatment process and creating a mini-ecosystem in the soil for even cleaner effluent.

Regular maintenance, including annual removal of accumulated sludge and scum, is key to maintaining system efficiency and preventing overflows or blockages. Our septic tank designs and maintenance solutions ensure the longevity and environmental safety of your septic system.

Common Signs of Septic Tank Drainage Problems

  1. Slow Draining Fixtures

One of the most noticeable septic tank problems is slow draining fixtures. When your sinks, toilets, and showers take longer than usual to drain, it could be a sign of a blockage or an issue within your septic system. It’s important not to ignore these early warning signs. Slow drainage often indicates that your tank is either full or experiencing other issues that need professional attention.

  • Odours and Smells

Unpleasant odours are a clear warning sign of septic tank problems. If you notice foul smells around your property, particularly near the drainage field or septic tank, it’s time to take action. These smells often indicate that waste is not being properly processed in the tank, leading to a buildup of gases and unprocessed sewage.

  • Backups and Blockages

Backups in your plumbing system, especially in lower areas like basements, can point to serious septic tank issues. If not addressed promptly, these blockages can lead to significant damage and health hazards. Regular checks and maintenance can help prevent such incidents.

  • Lush Grass or Algae Growth

An unusually lush patch of grass or algae growth near your septic tank area can be a septic tank seepage problem. Excess nutrients from a leaking tank can fertilise the soil, causing this overgrowth. While it might look healthy, it’s a sign that untreated effluent is escaping.

Preventing Septic Tank Drainage Problems

  1. Regular Pumping and Maintenance

Prevention is always better than cure. Regular pumping and maintenance of your septic tank are essential. At Calcamite, we recommend having your septic tank inspected and pumped every three to five years, depending on usage. Our team of experts can help ensure that your system is functioning optimally, preventing potential problems before they arise.

  • Proper Disposal Practices

What goes down your drains has a significant impact on your septic system. Avoid flushing non-biodegradable items, chemicals, or grease, as they can disrupt the delicate balance within your septic tank. Educating yourself and your household on proper disposal practices is a crucial step in protecting your septic system.
