Septic Tank Maintenance

Although sewers serve many city and suburban homes, many homes in small towns and rural areas rely on septic tanks for on-site treatment of waste water. For establishments that utilise septic tanks, the septic system may, perhaps, be the most important part of the inner mechanisms—just ask any property owner who has experienced septic tank problems or failure.

The septic system should responsibly eradicate and dispose of all waste material from the property. As an organic machine, it breaks down wastes and safely distributes the processed waste into a drain field on the property. Proper septic system maintenance is essential, and a comprehensive understanding of how your septic system works can give you a leg up in thwarting septic tank complications.

A septic tank separates and processes wastes. From the waste that flows into the tank, dense solids settle to the bottom, developing a layer of sludge. Greases, oils, and other lighter solids rise to the top, creating a layer of scum. The area between these two layers fills with liquid waste which flows through the outlet pipe to the drain field system.

The tank will typically store solids for around 3-12 years. The tank ought to be watertight, made in such a way that groundwater doesn’t leak into the tank and fluid seepage cannot leak out. If groundwater does leaks into the tank, it will increase the dissolved oxygen level within the tank, which will restrict the biological treatment, cause septic tank problems, and lead to early failure of the drain field.

The drain field should disperse a septic tank’s waste. Many drain systems have a series of trenches that spread out from a distribution box. Some have a single, larger bed. Others have a seepage pit or a similar means of distributing tainted water back into the ground.

Tank Inspection
Have your tank inspected by a septic tank professional every three to five years—more frequently if your family uses a lot of water. You can minimise the strain on your septic system by using less water and staggering showers, clothes washing, bathing, and other heavy usage.

Minimising the Strain on your Septic System
Increase the size of the absorption field. This will help if the original field was too small for the size of your family or if the soil does not allow water to permeate very well.

  • Conserve water in your home on a long-term basis. The smaller the amount of water flowing through your system, the longer the system will last.
  • Connect to a communal sewage system (if available).
  • If septic system failures are common in your area, consider participating in the development of alternatives. There are systems designed for small communities and some rural areas that are generally much more cost-effective than large sewer systems.
  • Water-saving devices and reduced consumption, especially in your bathroom, can have a significant effect.
  • Fence off the area. If liquid waste is seeping to the surface, prevent people and pets from getting in contact with the toxic waste.
