Frequently Asked Questions

  • What is a drainfield?

    The drainfield is the natural basin where liquid wastewater is sent from your septic system. This water is filtered through the soil and dispersed into the groundwater where it can begin the cycle again. Staying up-to-date with septic inspections and pumping will ensure this natural system functions smoothly.

  • Should I check my septic system myself?

    We recommend using a licensed professional to check your septic tank. However, if you choose to inspect your own system, be sure to remember that these tanks contain germs that cause disease and gases that are explosive and toxic. Avoid breathing fumes, and never have naked flames near an open system. Make sure the area is well-ventilated and always have someone watching you who can call for assistance. Be sure to switch off power to your home as well.

  • What are my responsibilities as a septic tank owner?

    Because septic tanks aren’t connected to the sewer, it is your job to ensure the water and waste from your home is draining properly. You should also stay up-to-date with septic pumping, maintenance and general checks. This will go a long way to ensuring your system functions smoothly and that no waste leaks into the drainfield. You must comply with local council regulations for installation, maintenance and inspections.

  • How do I know when my septic tank needs pumping?

    There are a few tell-tail signs your septic tank is full and requires pumping. Pooling water in the drainfield, backflow issues, foul odours—backed up or leaking septic liquid will make its presence known. If your lawn looks especially green and lush in one area, this is also a sign you need to have your tank pumped. The best practice is not to wait for these signs but to instead have your tank pumped once every 1 to 3 years.

  • How do I avoid drain blockages?

    Staying updated with routine inspections and maintenance is the best way to avoid blockages. On top of this, you can also avoid flushing wet wipes and napkins. Do not put grease, oil or any fat down your kitchen sink—these tend to stick to the sides of your pipes and will build up into blockages over time. Also, get into the habit of removing any hair from your shower floor after you are done bathing.
