For properties not connected to council sewerage systems, an individual septic system is crucial for
wastewater treatment and disposal. These systems include septic tanks, which need regular assessments to confirm the reliable and safe operation of the system. Ensuring a system is running at its best requires an understanding of how it works. Wondering what septic tanks do and how they feature within the wastewater treatment process? Read our handy guide to learn more.
Design and construction of a septic tank
Septic tanks are carefully built according to the specific scientific processes needed for the treatment of wastewater. They need to meet stringent design, construction and safety regulations before they can be sold and installed. They must also include access points for plumbing professionals to inspect critical elements.
Septic tank treatment
Once the waste reaches the
septic tank, “primary” treatment begins. The waste and solids in the water naturally sink to the bottom of the tank, where it forms sludge. Bacterial microorganisms then consume this material. As wastewater is lighter than sludge, it sits above the denser material. Scum floats both at the top of the
septic tank and above the sludge sitting on the bottom.
The digestion of sludge sends grease and oil to the top of the tank, where it collects into a protective crust settling over the wastewater. This layer prevents air from entering the tank and enables oxidation through bacteria. The water is then separated from the waste and undergoes continuing treatment and filtration within the tank. It also flows through absorption beds or mounts, which remove nutrients and microorganisms from the liquid. Finally, a disinfectant such as chlorine helps to eradicate any lingering parasites, viruses or bacteria. This ensures the water is completely safe for reuse.
Benefits of a septic tank
Septic tanks offer great benefits when included as part of a wastewater treatment system. They’re an environmentally-friendly way of recycling wastewater and are more affordable and easier to maintain than sewer lines. The design and manufacture of
septic tanks ensure they’re made to last. With the right care, steel tanks can easily run for 40 years.
