According to the law Q-2, r. 22, also known as the “Regulation on the Disposal and Treatment of Wastewater from Isolated Residences,” it is imperative to pump your septic tank every two years for a primary residence. More frequent pumping may be necessary for intensive use, such as commercial properties, multi-generational homes, home daycares, etc. For secondary or seasonal residences, pumping every four years is also mandatory.

Regular septic tank pumping is not just a legal obligation; it is also an effective means of possibly preventing potential issues and ensuring the proper functioning of your septic system.

However, pumping is only one part of the equation to guarantee the optimal performance of your septic system. In this regard, we share our septic tank expertise and provide other essential tips to maintain the proper functioning of your septic system. Explore practical recommendations, from protecting the leach field to avoiding certain items in your septic tank.

Here are some essential tips to maintain the proper functioning of your septic system:

Protect the leach field

The leach field of a septic tank is crucial during the final phase of wastewater treatment, facilitating the infiltration of treated water into the soil. To ensure the proper functioning and longevity of your septic system, it is crucial to avoid installing structures such as trampolines, ice rinks, or trailers over the leach field. Additionally, it is recommended to protect it from external elements such as snow or gardens. Heavy equipment or structures can compress the soil above the leach field, damaging the perforated pipes or drains within it, compromising its proper functioning.

Control the amount of water discharged

It is important to monitor the amount of water discharged into a septic tank to ensure the proper functioning of the system, prevent failures, optimize the efficiency of wastewater treatment, save water, and comply with environmental regulations. Septic tanks have a limited capacity for storing wastewater. Excessive water volume can exceed the tank’s capacity, leading to issues such as overflows, spills, and system malfunctions. It is recommended to follow water usage best practices and take measures to avoid overloading the septic system.

Pre-filter and regular cleaning

The pre-filter acts as an initial barrier by capturing heavier solid materials, such as food particles, sand, and other debris. It protects the septic tank from excessive overload, thereby extending its lifespan. Additionally, the pre-filter helps separate fats and oils floating on the surface, enhancing protection against excessive overload and increasing the septic tank’s longevity.

The installation or addition of a pre-filter to a septic tank, along with its regular cleaning, is essential to improve system efficiency, extend its lifespan, reduce the risk of clogging, and ensure compliance with environmental standards. Cleaning should be done according to the manufacturer’s recommendations or the guidance of a sanitation professional, considering the frequency of system use and wastewater characteristics.

Ensure easy access to septic tank covers

It is important to maintain the accessibility and visibility of your septic tank covers at all times. In winter, ensure snow removal and clear access to the covers. This precaution will facilitate inspections and pumping interventions, ensuring the proper functioning of the system even in cold weather. Additionally, during the summer season, avoid placing heavy objects such as gardening equipment or excessive grass on the covers. Easy access ensures unobstructed regular checks, contributing to the longevity and continued efficiency of your septic system.

Items to avoid in your septic tank

Septic tanks play a crucial role in wastewater treatment, but to ensure their proper functioning, it is crucial to be vigilant about the household products used. Careless use can compromise the biological balance of the septic tank and lead to various costly maintenance problems.

Here are some examples of products to avoid using or disposing of in your sinks and toilets:

  • Fabric softeners
  • Latex products
  • Antibacterial soaps
  • Cosmetics containing heavy metals
  • Drain cleaners like Drano
  • Bleach
  • Detergents with phosphates
  • Ground food
  • Oil or grease
  • Non-septic-safe toilet paper
