Frequently Asked Questions

  • How often do I need my septic tank cleaned?

    Generally, septic cleaning every three years is recommended for an average family of four. Septic tanks being used for larger families may need to be pumped out biannually. Getting your septic tank pumped out regularly will help protect your transpiration area and ensure the system continues to work efficiently.

  • Why is my septic tank smelling?

    An odour can be an indicator that your septic tank needs to be pumped out. It can also indicate an issue with the functioning of the system itself. When the sludge level gets too high, the tank will also become smelly.

  • What product should not be allowed into a septic system?

    Chemicals such as bleach should NEVER be introduced into your septic system. Please check product labels for guidance. Most good cleaning products will say if they are safe for septic tanks. Harsh cleaning products and detergents will kill the good bacteria that makes your system work effectively.

  • Do I need to be home for the service?

    Yes and no, depending on the type of system you have at your property. Most concrete septic systems can be serviced without anyone being present. Plastic septic tanks require refilling with clean water. Envirocycles DO require someone to be home as these larger systems require filling after servicing which may take several hours. Our professional team will explain the process to you. Please have a water hose available.

  • What sort of system do I have?

    • Septic: Generally, the water goes to a trench transpiration area, reed bed or sand mound on the property.
    • Envirocycle/biocycle: You will have a service agent checking your system every three months. These systems have pumps and aerators. After the water has been treated, it is generally recycled for use in your garden.
    • Pump out system: All wastewater flows into these systems. No septic or grey water is dispersed into the ground.

These systems sometimes have an indicator that lets you know when they need emptying. Remember that the less water you use, the less will need to be pumped out—be wise with your water usage.
