DO's and DON'Ts of septic systems

Learn how to manage your septic system

Septic Systems are usually installed in rural areas where sewerage systems aren’t available. If you have a septic system, it is important to maintain it regularly. In this article, we will discuss the do’s and don’ts of septic system use.

DO’s of septic systems

  1. The septic system should always be installed by a qualified professional.
  2. The septic system should be serviced every 4 months and desludging of the system should be done every 3 years.
  3. Clean the irrigation filters regularly to avoid clogging in the system.
  4. Plant tough and hardy grasses or bushes in the irrigation field that can tolerate the waste water.
  5. Use biodegradable products or products that are recommended to be safe for use in septic systems by the manufacturer.
  6. Divert the rainwater away from the irrigation field so that the drain field doesn’t become overly soggy. If it is too soggy, the drain field wouldn’t be able to absorb the liquid waste. 
  7. Install an effluent filter on your septic tank to prolong its life. 
  8. Conserve water by using full loads for your washing machine and dishwasher.
  9. Contact a licensed wastewater professional in case of any issue with the system.
  10. Ensure you have all the permits and approvals from your local council before you install or modify the system.

DON'Ts of septic systems

  1. Do NOT drive any vehicle over the drain field or septic tank as it could create pressure over the system and cause irreparable damage.
  2. Do NOT consume the treated water from the system and prevent animals from consuming the water as it can cause a serious health risk.
  3. Do NOT turn off the power supply as the system requires regular power supply.
  4. Do NOT enter the septic tank as gases generated inside the tank can be fatal. The septic tank cleaning needs to be cleaned from the outside. It is best left to the professionals. 
  5. Do NOT plant trees over the drain field as the roots can damage the system.
  6. Do NOT throw grease or oil down the drain as it can clog the sewer pipes.
  7. Do NOT add bacteria or any septic tank additives to the system.
  8. Avoid overusing cleaning agents like bleach or disinfectants as they are harmful for the septic system.
  9. Avoid flushing or washing the following products :
    • Sanitary products like tampons or pads
    • Condoms
    • Nappies
    • Solid waste like plastic, and coffee grounds
    • Food scraps
    • Solvents, paints or thinners
    • Bleaching agents
    • Paper
    • Antibacterial products like wet pipes
    • Cigarette butts
    • Bath bombs
    • Insecticide, pesticides, and herbicides
    • Medicines

Note: Anything which isn’t biodegradable should not be washed or flushed as they kill the bacteria present in the septic tank.
