Frequently Asked Questions (FAQs) about Septic Systems

  • 1. What is a septic system?

    A septic system is an on-site wastewater treatment system commonly used in areas without access to municipal sewer systems. It consists of a septic tank and a drainfield, where wastewater is treated and filtered before returning to the soil.

  • 2. How does a septic system work?

    Wastewater from a property flows into the septic tank, where solids settle and are partially decomposed by bacteria. The liquid wastewater then exits the tank and flows into the drainfield, where it is further treated by soil organisms before being absorbed into the ground.

  • 3. How often should a septic system be pumped?

    The frequency of septic tank pumping depends on several factors, including the size of the tank, the number of occupants in the household, and the volume of wastewater generated. As a general rule, septic tanks should be pumped every 3 to 5 years to remove accumulated solids and prevent system failure.

  • 4. What are the signs that a septic system may be failing?

    Signs of septic system failure include slow draining sinks and toilets, gurgling sounds in plumbing fixtures, sewage backups, foul odors around the drainfield, and lush, green grass over the septic tank or drainfield area. If you notice any of these signs, it's important to have the system inspected promptly.

  • 5. Can I build over or landscape on top of my septic system?

    Building structures or landscaping over a septic system can potentially damage the system and disrupt its function. It's essential to know the location of your septic tank and drainfield and avoid any construction or heavy planting in these areas to prevent damage.

  • 6. How can I maintain my septic system?

    Regular maintenance is key to ensuring the longevity and efficiency of a septic system. This includes having the tank pumped regularly, conserving water to reduce strain on the system, avoiding flushing non-biodegradable items, and being mindful of what goes down the drains.

  • 7. Do I need a permit to install or repair a septic system?

    Yes, most jurisdictions require permits for the installation, repair, or modification of septic systems. It's important to check with your local health department or building authority to determine the specific requirements and obtain the necessary permits before undertaking any work on your septic system.

  • 8. What is a septic system inspection, and why is it important?

    A septic system inspection involves assessing the condition and functionality of the system, including the tank, drainfield, and associated components. Inspections are crucial for identifying potential issues early on, ensuring compliance with regulations, and facilitating property transactions.

  • 9. Can I use additives to improve the performance of my septic system?

    While some products claim to enhance septic system performance, experts generally advise against using additives. These products can disrupt the natural balance of bacteria in the tank and may not provide any significant benefits. Regular maintenance and proper usage are more effective strategies for maintaining a healthy septic system.

  • 10. What should I do if I suspect a problem with my septic system?

    If you suspect a problem with your septic system, such as foul odors, sewage backups, or unusual drainage issues, it's important to contact a qualified septic system professional for an inspection. Ignoring potential problems can lead to costly repairs and environmental contamination.

Dos and Don'ts for Septic Systems

Do’s:

  1. Do conserve water: Use water efficiently by fixing leaks, installing low-flow fixtures, and spreading out water usage throughout the day to avoid overwhelming the system.
  2. Do pump your septic tank regularly: Schedule routine pumping every 3 to 5 years to remove accumulated solids and prevent clogs and system failure.
  3. Do maintain records: Keep detailed records of septic system maintenance, including pumping dates, inspections, and repairs, to track the system's performance and compliance with regulations.
  4. Do practice proper waste disposal: Dispose of household waste properly by avoiding flushing non-biodegradable items such as wipes, sanitary products, grease, and chemicals down the drains.
  5. Do direct surface water away from the drainfield: Ensure that surface water from roofs, driveways, and other surfaces is directed away from the drainfield to prevent saturation and potential system overload.
  6. Do plant grass over the drainfield: Planting grass over the drainfield can help absorb excess moisture and prevent erosion while also providing natural filtration for wastewater.
  7. Do have your septic system inspected regularly: Schedule periodic inspections by qualified professionals to assess the condition of the system, identify potential issues, and ensure compliance with regulations.
  8. Do know the location of your septic tank and drainfield: Familiarize yourself with the layout of your septic system to avoid accidental damage during landscaping, construction, or excavation projects.

Don'ts:

  1. Don't overload the system with water: Avoid excessive water usage, such as running multiple appliances simultaneously or doing all laundry in a single day, as it can overwhelm the system and lead to backups or failures.
  2. Don't flush inappropriate items: Never flush non-biodegradable items like diapers, paper towels, cigarette butts, or pharmaceuticals down the toilet, as they can clog pipes and disrupt the system's function.
  3. Don't pour chemicals down the drains: Refrain from pouring harsh chemicals, solvents, paints, or medications down the drains, as they can harm the beneficial bacteria in the septic tank and contaminate groundwater.
  4. Don't park or drive over the septic system: Avoid parking vehicles or heavy machinery over the septic tank or drainfield, as the weight can compact the soil, damage pipes, and disrupt the system's operation.
  5. Don't plant trees or shrubs near the drain field: Keep trees and shrubs with deep roots away from the drain field to prevent root intrusion, which can clog pipes and interfere with the absorption of wastewater.
  6. Don't ignore signs of system failure: Pay attention to warning signs such as foul odors, slow drains, sewage backups, or unusually lush vegetation over the drainfield. Ignoring these signs can lead to costly repairs and environmental damage.
  7. Don't attempt DIY repairs unless qualified: Avoid attempting to repair or modify your septic system yourself unless you have the necessary expertise and permits. Improper repairs can worsen existing problems and may violate local regulations.
  8. Don't neglect routine maintenance: Regular maintenance is essential for the proper functioning of your septic system. Neglecting maintenance tasks such as pumping the tank or inspecting for leaks can lead to costly repairs and environmental contamination.
