How Often Should a Septic Tank Be Pumped?

One of the most important aspects of maintaining a healthy septic tank and septic system is to regularly service the septic tank via pumping. How often should the task of pumping a septic tank be performed? Great question! The answer may vary based on multiple factors, including the size of your household and your daily water usage. Let’s explore what you need to know to keep your septic system running as efficiently and effectively as possible.

Understanding Septic Tank Pumping

Septic tank pumping involves the removal of built-up solids and scum from your septic tank. This action of removal helps to prevent clogs and will ensure your system processes waste effectively. If the septic tank is not pumped regularly, solids begin to accumulate, potentially leading to all-out septic system failure, unpleasant odors, and costly repairs. 

Factors Influencing Pumping Frequency

Amount of Wastewater Generated

Daily habits which increase water usage, such as a large number of loads of laundry, several dishwasher cycles per day, and long showers from each individual in your household may prove to be the cause of why your septic tank is filling up so quickly. More water usage means less time for solids to settle before they are pushed on through the system, which can cause issues further down the line.

Use of Garbage Disposal

Using a garbage disposal may increase the amount of grease and organics entering the tank and may lead to more frequent pumping.

Types of Waste

Flushing things like grease, excessive amounts of cleaning products such as fabric softener or bleach, as well as certain pharmaceutical drugs can lead to a kill-off of bacteria colonies inside your septic system which can lead to bad smells, incomplete treatment, and/or backups of your system

General Guidelines for Pumping Frequency

As a rule of thumb, it is recommended to pump your septic tank every three to five years. However, the following schedule offers a much more tailored guideline based on tank size and household size:

• 1-2 People: Every 5-6 Years

• 3-5 People: Every 4-5 Years

• 6+ People: Every 1-3 Years

These are of course estimates, yet it can vary depending on the specific conditions of your septic system and usage patterns.

Signs Your Septic Tank Needs to Be Pumped

Even if it hasn’t been that long since your last service, you’ll want to watch out for signs that your tank needs to be pumped sooner:

Frequent Backups: If your home suddenly starts experiencing frequently clogged pipes, that could be a sign your tank has too much trash built-up in your tank, causing draining issues.

Unpleasant Odors: If you begin to smell sewage in your yard or near your system’s distribution field, it may be a sign of an overflowing septic tank.

Water Pooling: When water pools in the drain field area, it may indicate a damaged field line, or overuse of the system in general.
