What You Need to Know About Septic Tanks in Your Business

What is a septic tank?

When wastewater is not connected to sewerage, it is stored in a septic tank or a holding tank to collect. Septic tanks are typically located underground and consist of both inlet and outlet piping. When water waste enters the tank through the inlet pipe, a digestion process begins converting solids into a sludge that settles at the bottom of the tank and will require removal. Lighter liquids such as oil, grease, and other scum floats on top of the tank. The remaining wastewater flows outside the tank using the outlet pipe and into a leach drain leaving the solids inside the tank.

When and why do septic tanks to need to be pumped out?

As the solids increase, the space between the two layers will continue to get smaller, resulting in the septic tank clogging up and overflowing the system. To prevent a septic tank from causing problems it needs a routine pump out to prevent the solids from accumulating. The frequency will depend on the size of the business (i.e., frequency of use) and can range from a once or twice a year service through to every three or four years.

A pump out will also:

  1. Ensure bad odours are minimised;
  2. Minimise the possibility of blocked drains;
  3. Improve drainage and toilet flushing;
  4. Minimise damage to pipes.

  1. Wet areas near the septic tank;

  5. Foul odour from toilet;
