19 Septic System Facts

What is a Septic System?

A septic system is an underground wastewater treatment system commonly used in areas without access to public sewer systems. It consists of a septic tank and a drainfield, where the wastewater is treated and dispersed into the soil naturally.

How Does a Septic System Work?

The septic system works by separating solid waste from wastewater. Solid waste settles at the bottom of the tank, while the liquid wastewater flows out into the drainfield. Bacteria in the tank help break down the solid waste, allowing it to decompose over time.

Regular Maintenance is Crucial

Regular maintenance is essential to keep a septic system functioning properly. This includes pumping the septic tank every 3-5 years, inspecting the system for any issues, and avoiding disposing of harmful substances down the drains.

The Importance of Proper Disposal

It is crucial to dispose of waste properly to prevent septic system problems. Flushing non-biodegradable items such as diapers, paper towels, or feminine hygiene products can clog the system and lead to costly repairs.

Septic Systems Can Fail

If a septic system is not properly maintained, it can fail. Signs of a failing system include slow drains, foul odors, standing water in the drainfield, or sewage backup. Timely repairs and maintenance can help prevent system failure.

Location Matters

The location of the septic system is important for its proper functioning. It should be placed in an area with adequate soil percolation and away from wells, bodies of water, and property lines to avoid contamination risks.

Size Matters Too

The size of a septic system should be determined based on the household’s water usage. A system that is too small for the household’s needs may lead to overflows and backups, while an oversized system may be wasteful.

Water Conservation Helps

Conserving water is beneficial for both the environment and the septic system. Excessive water usage can overload the system and hinder its ability to treat wastewater effectively.

Additives Are Not Always Necessary

Contrary to popular belief, septic system additives are often unnecessary and can even disrupt the natural balance in the tank. Proper maintenance and regular pumping are usually sufficient to keep a septic system in good condition.

Septic Systems can be Environmentally Friendly

When properly designed and maintained, septic systems can be environmentally friendly. Natural processes within the system help remove pollutants from the wastewater, allowing it to be safely returned to the groundwater.

Soil Type Affects System Performance

The type of soil in the drainfield area can significantly impact the performance of a septic system. Soil with good percolation rates, such as sandy or loamy soil, allows for proper wastewater absorption and treatment.

Grease Should Not Enter the System

Grease and fats should never be disposed of down the drains as they can clog the system. Properly disposing of grease by collecting it in containers and disposing of it in the trash helps prevent septic system issues.

Regular Inspections Are Recommended

Having a professional inspect the septic system regularly can help identify potential issues early on and prevent costly repairs. A thorough inspection can assess the condition of the tank, drainfield, and other components.

Tree Roots Can Cause Damage

Tree roots can infiltrate septic systems, causing damage to pipes and disrupting the system’s functionality. It’s important to plant trees and bushes away from septic system components to avoid such issues.

Harsh Chemicals Harm the System

Using harsh chemicals, such as bleach, drain cleaners, or excessive amounts of antibacterial soaps, can harm the beneficial bacteria in the septic system. It’s best to use environmentally friendly and septic-safe products.

Winter Maintenance is Essential

In cold climates, it is crucial to take extra precautions during winter to prevent freezing and damage to the septic system. Insulating exposed pipes, avoiding compacting snow over the drainfield, and fixing any leaks promptly are essential steps to take.

Septic Systems have a Lifespan

Septic systems have a lifespan, typically ranging from 25 to 30 years. Proper maintenance and regular inspections can extend the lifespan of the system and minimize the need for premature replacements.

Professional Help is necessary for Repairs

If a septic system requires repairs, it is crucial to seek professional help. Attempting DIY repairs without proper knowledge and expertise can lead to further damage and costly repairs in the long run.

Local Regulations Apply

Each locality may have specific regulations regarding septic systems. It is essential to be aware of these regulations and obtain the necessary permits and inspections when installing or maintaining a septic system.

Conclusion

In conclusion, septic systems play a crucial role in managing household wastewater effectively. Understanding the key facts about septic systems is essential for homeowners to ensure proper maintenance and avoid any potential issues. Remember to regularly pump and maintain your septic tank, conserve water, and be mindful of what you flush down the drains. By following these guidelines and seeking professional assistance when needed, you can extend the lifespan of your septic system and ensure a clean and healthy environment for your home and community.

FAQs

1. How often should I have my septic system pumped?

On average, it is recommended to have your septic system pumped every 3 to 5 years. However, the frequency may vary depending on the size of your tank, the number of occupants in your household, and your water usage.

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

While there are septic system additives available in the market, their effectiveness is controversial. It is best to rely on proper maintenance practices such as regular pumping, avoiding excessive water usage, and being cautious about what you flush down the drains.

3. Can I plant trees or shrubs near my septic system?

It is not advisable to plant trees or large shrubs near your septic system. The roots of these plants can invade the sewer lines and cause damage, leading to potential leaks and blockages.

4. How can I tell if my septic system is failing?

Signs of a failing septic system include slow drains, sewage backups, foul odors near the drain field, and lush, overly green grass over the leach field. If you notice any of these signs, it is important to contact a professional to assess the situation and make necessary repairs.

5. Can I build a swimming pool or driveway over my septic system?

No, it is not advisable to build structures such as swimming pools or driveways over your septic system. These heavy structures can put excessive pressure on the system, leading to damage and potential malfunctions.
