What to Avoid Putting in Your Septic System: Essential Guidelines for Virginia Residents

Maintaining a healthy septic system in Virginia requires more than routine maintenance; it also involves being mindful of what goes into your system. Certain items and substances can disrupt the balance of bacteria in the tank, clog pipes, and ultimately lead to system failure. In this guide, we will outline essential guidelines on what not to put into your septic system to ensure its longevity and efficiency.

1. Non-Biodegradable Items:

Avoid flushing non-biodegradable items down the toilet, such as:

– Baby wipes

– Paper towels

– Feminine hygiene products

– Dental floss

These items can clog pipes and hinder the decomposition process in your septic tank.

2. Harsh Chemicals:

Avoid pouring harsh chemicals, such as bleach, drain cleaners, and paint thinners, down the drain. These chemicals can disrupt the natural balance of bacteria in the septic tank, leading to system imbalances and reduced efficiency.

3. Grease and Cooking Oils:

Avoid pouring grease, fats, and cooking oils down the drain. These substances solidify in the septic tank, causing blockages and reducing the tank’s capacity to break down waste effectively.

4. Medications and Personal Care Products:

Avoid disposing of medications, antibiotics, and personal care products down the drain or toilet. These substances can interfere with the bacterial balance in the septic tank and harm the environment if they leach into the groundwater.

5. Excessive Water Usage:

Avoid overloading your septic system by conserving water and spreading out water usage throughout the day. Excessive water can overwhelm the system, leading to backups and poor drainage.

6. Coffee Grounds and Food Waste:

Avoid disposing of coffee grounds, eggshells, and food scraps in the garbage disposal. These items can accumulate in the septic tank and contribute to clogs and odors.

7. Heavy-Duty Cleaners:

Avoid using heavy-duty cleaners and antibacterial products excessively. These cleaners can kill the beneficial bacteria in the septic tank, disrupting the decomposition process.


By being mindful of what goes into your septic system in Virginia and following these guidelines on what not to put into your system, you can prevent costly repairs, extend the life of your septic system, and protect the environment. Encourage proper waste disposal habits among residents to maintain a healthy and efficient septic system for years to come.
