Gravity Septic Tanks

Gravity septic tanks are the most common type of septic tanks used in residential properties. As the name suggests, they rely on gravity to move wastewater from the house to the tank and then to the drain field. These tanks are typically made of concrete and have one or two compartments.

  • Advantages:
  • – Simple and cost-effective design
  • – Low maintenance requirements
  • – Long lifespan if properly maintained
  • However, they are not suitable for properties with uneven terrain or high water tables, as they require a slope for the wastewater to flow correctly.

    Pump Septic Tanks

    Pump septic tanks, also known as pressure distribution septic tanks, are an alternative to gravity tanks. These tanks use a pump to move wastewater from the house to the tank and then evenly distribute it to the drain field. They are often used in areas with challenging terrain or high water tables.

  • Advantages:
  • – Suitable for properties with uneven terrain or high water tables
  • – Can handle larger wastewater volumes
  • – More flexibility in locating the drain field
  • However, pump septic tanks require regular maintenance to ensure the pump is functioning correctly, and they are generally more expensive to install and maintain compared to gravity tanks.

    Alternative Septic Systems

    In some cases, traditional septic tanks may not be suitable for certain properties due to soil conditions, space limitations, or environmental considerations. In these situations, alternative septic systems can be used to provide wastewater treatment and disposal.

    One example of an alternative septic system is the aerobic treatment unit (ATU). ATUs use oxygen and bacteria to break down organic matter more efficiently than traditional septic tanks. This process reduces the amount of solid waste and produces a cleaner effluent. ATUs are often used in environmentally sensitive areas.

    Another example is the mound system, which is designed for properties with inadequate soil depth or permeability. Mound systems use a raised bed of sand or gravel to filter and treat wastewater before it is released into the soil.

    It’s essential to consult with a professional and follow local regulations when considering alternative septic systems to ensure compliance and proper installation.

    Maintenance and Care

    Regardless of the type of septic tank you have, proper maintenance and care are crucial to prevent issues and ensure the longevity of the system.

  • Regular inspections: Schedule regular inspections to assess the tank’s condition and check for any signs of malfunction or damage. A professional can perform a thorough inspection and recommend any necessary repairs or maintenance.
  • Pumping: Regular pumping is necessary to remove accumulated solids from the tank. This prevents clogs and ensures proper wastewater treatment. The frequency of pumping depends on the tank’s size, usage, and number of occupants.
  • Water usage: Be mindful of the water usage in your household. Excessive water usage can overload the septic system and lead to issues. Implement water conservation practices, such as fixing leaks and using water-efficient fixtures.
  • Avoid certain materials: Do not dispose of non-biodegradable materials, such as paper towels, baby wipes, or feminine hygiene products, in the septic system. These can clog the pipes and cause damage to the tank.
  • By following these maintenance practices, you can ensure the efficient and reliable operation of your septic system for years to come.
