Determining when a septic tank needs to be emptied can be done in a few ways. First, you can check the designed storage level provided by the manufacturer and consider the tank’s volume and the number of people using it. If the tank is designed for more occupants than you have, it will likely last longer before needing to be emptied. Typically, septic tanks can last anywhere from six months to a year before requiring pumping.
For a more accurate measurement, sludge level pipettes can be used. These dipsticks can gauge the amount of sludge volume in the tank, and the manufacturer will provide the maximum volume before it needs to be discharged. However, this measurement is often carried out by a service engineer, especially for treatment plants.
While septic tanks require less monitoring, it’s still important to consider the sludge levels and the recommended frequency for emptying to ensure proper maintenance.
