Maintaining Your Septic System

A properly maintained septic system is essential for safely treating wastewater and preventing contamination of your property and surrounding environment. Regular maintenance of your septic system ensures that it operates efficiently and reduces the risk of costly repairs, backups, or system failures.

This article provides a comprehensive guide to Septic System Maintenance, including tips on inspecting, pumping, and caring for your Septic Tank and drain field.

Understanding How Your Septic System Works

Your septic system treats and disposes of wastewater from your home. It typically consists of two main components: the septic tank and the drain field (also known as the Leach Field).

Septic Tank: The septic tank holds wastewater from your home. Solids settle at the bottom of the tank, forming sludge, while grease and oils float to the top, creating scum. Bacteria in the tank help break down these solids. The liquid Effluent in the middle is filtered out to the drain field.
Drain Field: The effluent flows from the septic tank into the drain field, where it is distributed through a series of perforated pipes. The soil in the drain field filters and further treats the effluent before it returns to the Groundwater system.

Maintaining these components helps prevent backups, slow drainage, and potential contamination of groundwater.

Regular Septic Tank Inspections and Pumping

One of the most important aspects of septic system maintenance is regular inspection and pumping of the septic tank. Over time, sludge and scum build up in the tank, reducing its capacity and effectiveness.

Schedule Regular Inspections: Have a professional inspect your septic system every 3-5 years, or more frequently if your household uses a lot of water. During an inspection, the technician will check the tank’s levels, assess its condition, and ensure that the system is functioning properly.
Pump the Tank Every 3-5 Years: Septic tanks need to be pumped regularly to remove the sludge and scum that accumulate. The frequency of pumping depends on the size of your tank, the number of people in your household, and your water usage. As a general rule, tanks should be pumped every 3-5 years to prevent solids from clogging the drain field or causing backups in your home.
Watch for Signs of Trouble: If you notice slow drains, gurgling sounds from your Plumbing, foul odors, or pooling water near your drain field, these may be signs that your septic system is full or failing. If any of these symptoms occur, schedule an inspection and pumping as soon as possible.

Proper Water Usage to Avoid Overloading

Excessive water use can overwhelm your septic system, reducing its ability to treat wastewater effectively. By conserving water and spreading out usage, you can reduce the strain on your septic system and extend its lifespan.

Fix Leaky Faucets and Toilets: Even small leaks can add up, contributing to excess water entering your septic system. Regularly check for and repair leaks to avoid overloading the tank.
Use Water-Efficient Appliances: Installing water-efficient appliances, such as low-flow toilets, faucets, and showerheads, helps reduce the amount of water entering your septic system. ENERGY STAR-certified dishwashers and washing machines also use less water, further reducing strain on your system.
Spread Out Laundry and Dishwasher Loads: Running multiple loads of laundry or using the dishwasher several times a day can overwhelm your septic system with large volumes of water at once. Instead, spread out laundry and dishwashing tasks over the course of the week to allow your system time to process wastewater efficiently.
Install a High-Efficiency Toilet: High-efficiency toilets use less water per flush, which can significantly reduce the amount of water flowing into your septic tank. This simple upgrade can help extend the time between pumpings and improve overall system performance.

Proper Waste Disposal Practices

What you flush or drain can have a significant impact on your septic system’s health. Some materials can clog pipes, damage the septic tank, or kill beneficial bacteria, leading to system failure.

Only Flush Human Waste and Toilet Paper: Your septic system is designed to handle human waste and biodegradable toilet paper. Avoid flushing items like paper towels, sanitary products, diapers, or “flushable” wipes, as these materials don’t break down easily and can clog your system.
Avoid Chemical Cleaners and Antibacterial Products: Harsh chemicals, bleach, and antibacterial cleaners can kill the beneficial bacteria in your septic tank that break down solids. Use septic-safe cleaning products and limit the amount of chemicals you introduce into the system.
Dispose of Grease Properly: Cooking grease, fats, and oils can solidify in your pipes or septic tank, leading to clogs and backups. Instead of pouring grease down the drain, let it cool and dispose of it in the trash.
Limit Use of Garbage Disposals: Garbage disposals can add extra solids to your septic tank, increasing the frequency of pumping and the risk of clogs. If you use a Garbage Disposal, be mindful of what you grind, and consider composting food waste instead.

Maintaining Your Drain Field

The drain field is a critical part of your septic system, responsible for filtering and dispersing the effluent from the septic tank. Proper care of the drain field is essential to maintaining the system’s functionality.

Keep the Area Clear: Never build structures, park vehicles, or plant trees over your drain field, as these can compact the soil or damage the pipes. Grass is the best cover for the drain field, as it helps prevent erosion without obstructing the flow of effluent.
Redirect Rainwater Away from the Drain Field: Excess water in the drain field can saturate the soil and prevent the system from working properly. Make sure your gutters, downspouts, and landscaping are designed to direct rainwater away from the drain field to avoid waterlogging.
Limit Water Usage During Heavy Rains: When your yard is already saturated from heavy rain, avoid doing large loads of laundry or using a lot of water. This gives your septic system time to catch up and prevents overloading the drain field.
Watch for Signs of Drain Field Issues: If you notice spongy or soggy ground, foul odors, or standing water near your drain field, it may be a sign that the system is overloaded or failing. If you observe these symptoms, contact a professional for an inspection.

Septic Additives: Are They Necessary?

There are many septic additives on the market that claim to improve the performance of your system by boosting bacterial activity. However, most septic systems do not need additives if they are properly maintained.

Consult with a Professional: Before using any septic additives, consult a professional. Some additives can disrupt the natural balance of bacteria in your tank and do more harm than good. In most cases, regular inspections, pumping, and proper waste disposal are all you need to keep your system functioning well.

What to Do in Case of a Septic System Failure

A septic system failure can cause wastewater to Back Up into your home or leak into your yard, posing health risks and environmental hazards. Knowing how to respond quickly can prevent further damage.

Stop Using Water Immediately: If you suspect your septic system is failing, reduce water usage immediately to prevent further strain on the system. Avoid using toilets, sinks, and appliances that drain into the system until the issue is addressed.
Call a Professional: Contact a licensed septic system Contractor for an inspection and diagnosis. They can determine the cause of the failure and recommend appropriate repairs, whether it’s a clogged pipe, a full tank, or a damaged drain field.
Avoid DIY Repairs: Septic system repairs require specialized knowledge and equipment. Attempting to repair a failing system yourself can cause more damage or expose you to harmful bacteria. Always rely on a professional for septic system repairs.
