Many modern sewer systems, including ATUs, come with alarms that notify you of issues such as low air pressure or system malfunctions. If your alarm goes off:

  1. Do not ignore it. The alarm is designed to alert you to problems that may need professional attention.
  2. Contact a professional: Reach out to a licensed service provider or installer to inspect the system and perform necessary maintenance.

Recognizing the early signs of a failing sewer system can help you avoid costly repairs and health hazards. Look out for these common indicators:

  • Slow drains: If your sinks, showers, or toilets drain slowly, it may indicate a clog or backup in your septic system.
  • Unpleasant odors: Foul smells around the drain field, septic tank, or inside your home could mean there is a problem with the system.
  • Standing water or wet spots: If you notice soggy patches of ground near the septic tank or drain field, this could be a sign of overflow or system failure.
  • Backed-up sewage: A severe backup of sewage inside the house is a major red flag that your septic system is malfunctioning and needs immediate attention.
  • Lush green grass over the drain field: If the grass over your drain field is unusually green and lush, it may indicate an excess of untreated wastewater.

If you notice any of these symptoms, it’s important to call a professional sewer service provider for an inspection and possible repair.

As a sewer system owner, there are a few key responsibilities to ensure your system works properly and lasts longer:

  • Keep the area clear: Avoid placing vehicles, heavy equipment, or structures over your septic tank or ATU. Roots or pests (like fire ants) should be kept away from the system.
  • Monitor the system: Regularly check the system’s operation and make sure the control panel is functioning properly. If your system has an alarm, ensure it’s working and responds to malfunctions.
  • Avoid overloading: Use water efficiently, and avoid flushing non-biodegradable items or harmful chemicals (like bleach or disinfectants).
  • Professional service only: Always have licensed professionals perform inspections and repairs. Unauthorized servicing can cause damage or void your warranty.

Many modern sewer systems, including ATUs, come with alarms that notify you of issues such as low air pressure or system malfunctions. If your alarm goes off:

  1. Do not ignore it. The alarm is designed to alert you to problems that may need professional attention.
  2. Contact a professional: Reach out to a licensed service provider or installer to inspect the system and perform necessary maintenance.

The frequency of sewer system pumping depends on the type of system you have and how much water your household uses. Here are some general guidelines:

  • Septic tanks: Pump every 3-7 years, depending on your water usage and the size of your tank.
  • Aerobic Treatment Units (ATUs): These systems typically require less frequent pumping due to their more efficient treatment, but you may still need to pump every 5-10 years or as needed.

 

Regular maintenance checks are crucial. If you notice odors, slow drainage, or unusual discharges, it may be time for an inspection or pump-out.

For your sewer system to function efficiently, it’s important to use only approved products. Here’s a list of safe items for your system:

  • Household cleaners: It’s safe to use household cleaners in moderation, provided they follow the directions on the label. Avoid excessive use, especially with bleach or harsh chemicals.
  • Toilet paper: Only use biodegradable toilet paper designed for septic systems.
  • Laundry detergent: Use sewer-safe detergents in recommended amounts.

 

However, certain products should never go into your sewer system, including:

  1. Large amounts of bleach or disinfectants that kill bacteria
  2. Feminine hygiene products, diapers, and other non-biodegradable items
  3. Cooking oils, grease, coffee grounds, or shrimp shells
  4. Chemical drain cleaners
  5. Plastics, rubber, and large paper products

 

These items can harm the system’s bacteria or cause blockages, reducing efficiency and increasing maintenance needs.

Both Aerobic Treatment Units (ATUs) and septic tanks treat wastewater, but they use different methods:

  • Septic Tank: A septic tank relies on anaerobic bacteria (bacteria that do not require oxygen) to break down waste. The wastewater is held in the tank where solids settle, and liquids are filtered out. Over time, sludge builds up at the bottom of the tank, requiring periodic pumping.
  • Aerobic Treatment Unit (ATU): An ATU uses aerobic bacteria (bacteria that require oxygen) to break down organic waste. Air is pumped into the unit, promoting a more efficient biological process. This method results in cleaner effluent (treated wastewater) and often requires less frequent pumping.

 

Key Differences:

  • Aerobic systems (ATUs) are generally more efficient, producing cleaner treated water and requiring less maintenance.
  • Septic tanks are simpler but can require more frequent pumping and can produce less treated effluent.
