The Berea Resident’s Guide: How Your Septic Tank System Actually Works

Septic tank guide

Many people move into  Berea. Whether you bought a Victorian home in Glenwood or a hidden gem in Morningside, your property likely has a unique feature. Specifically, your home does not connect to the municipal sewer line. Instead, you own a septic tank system.

Moving from other  suburbs can make these systems feel like a mystery. However, we at Aquafix Plumbing Services know that understanding your tank prevents “the big stink.” Knowledge also stops costly emergency repairs before they start.

Consequently, this guide explains exactly how these systems function. We also highlight the specific challenges posed by our local Berea Red Sand.

What is a Septic Tank System?

Essentially, a septic tank is your own private, underground wastewater treatment plant. Since your property isn’t linked to Durban’s central sewage grid, all the water that leaves your home—from your toilets and showers to your kitchen sink—must be treated on-site.

Two Core Components

To understand the process, you must look at these two main parts

1. 1. The Septic Tank: This watertight container sits buried in your garden. In older Berea homes, builders usually  used brick or concrete.

   2. The Soakaway (French Drain): This component consists of stone-filled trenches or a deep pit. It filters treated water back into the earth.

How the Process Works: The “Three Layer” System

When you flush a toilet, the waste travels through a main pipe into the tank. At this point, natural bacteria begin to work. The tank holds the water long enough for it to separate into three distinct layers:

• The Scum Layer (Top): Fats, oils, and grease float to the surface.

• The Effluent Layer (Middle): This relatively clear water is the only part that should exit the tank.

• The Sludge Layer (Bottom): Heavy solids sink here. Bacteria break these down over time, though they never vanish completely.

The Risk: If the sludge grows too thick, it overflows. Consequently, solids enter your soakaway and clog the soil. On the compact residential lots of the Berea, this creates a massive, expensive mess.

The “Berea Factor”: Soil and Durban Weather

Living on the Berea ridge presents unique plumbing challenges.

1. The Berea Red Sand

Our area is famous for Berea Red Sand. While this soil usually drains well, it can “blind” or clog after decades of use. Furthermore, intense Durban summer storms saturate the ground quickly. If your tank is full, you will notice gurgling drains immediately after a downpour.

2. Tropical Root Intrusion

The Berea features beautiful, lush vegetation. However, these tree roots constantly seek water. They find tiny cracks in old brick tanks and grow inside. Eventually, these roots cause total blockages.

3. Humidity and Odors

Durban’s heat actually helps bacterial growth. Nevertheless, high humidity can trap sewer gases near the ground. If your vent pipes are too low or blocked by creepers, you will notice a “rotten egg” smell on humid nights.
