Discover a few tips to tell the difference between septic tank cleaning and pumping. You never know when you may need either one.

Often the terms “cleaning” and “pumping” are used interchangeably when referring to septic tanks. However, there is a slight difference between these two terms. Cleaning a septic tank refers to removing all the water from the septic tank, including the accumulated sludge at the bottom. While pumping a septic tank refers to removing liquids and some floating debris. With an average of 70 gallons of water being used in a single-family home, it’s only a matter of time before your septic tank will need cleaning or pumping.

There are some typical signs that your septic tank needs cleaning:

  1. Strong odors
  2. Backed up sewage
  3. Gurgling noises
  4. Frequently clogged drains
Pumping

The EPA recommends that septic tanks should be pumped out every three to five years. A professional should inspect your septic tank every two to three years to ensure it is functioning properly and there are no problems.

When pumping out a septic tank, some of the sludge and floating solids are removed along with the liquid from the tank. This must be done before the sludge accumulates and clogs the drain pipe. The sludge flows out of the drain pipe into the drain field.

A professional septic service technician will advise you when you need to have your tank pumped. This usually happens when the scum layer is about six inches from the drain pipe.

A large tanker truck with vacuum equipment is used. The technicians insert a large hose through the manhole into the septic tank. They then vacuum the contents of the septic tank. The technicians stir the contents of the tank to break up the solids and mix them with the liquids. This makes the disposal of waste much easier.

Cleaning

Septic tank cleaning, on the other hand, means removing all liquids and sludge from the bottom of the septic tank. The same procedure applies to cleaning the septic tank. This procedure is much more thorough because, instead of removing only a portion of the sludge, all of the sludge is removed and the tank is properly emptied.

Septic tank cleaning is much better for the system as a whole as it ensures that all of the sludge that may cause a blockage is removed. If the system is cleaned out regularly, then removing solid waste is much easier. Septic systems are expensive to replace and therefore require proper maintenance and cleaning.

Popular FAQs

Aerobic septic installation cost vs conventional systems in central Oklahoma, what should homeowners expect?2025-11-23T19:20:28-06:00

In Central Oklahoma, aerobic septic systems generally cost more than residential conventional systems, but the gap depends heavily on soil conditions and the required lateral footage. A typical residential conventional system may range from $5,000–$8,000, while a residential aerobic system—with treatment tanks, control panel, and spray equipment—typically runs $7,500–$12,500.

In recent years, however, rising material costs for gravel and chambers have pushed some large-footprint conventional systems above the cost of aerobic installations.

Aerobic systems carry higher base equipment costs, but conventional systems can become more expensive when large absorption areas are required. Because many Central Oklahoma soils contain dense clay, aerobic systems are often the only DEQ-approved option on many lots.

Red Dirt Septic, the state’s leading installer with more than 12,000 systems installed or serviced statewide, designs each system for regulatory compliance, cost efficiency, and long-term performance.

Can overusing water damage my septic tank?2026-05-14T08:53:26-06:00

Yes. Septic tanks have a finite daily capacity. When too much water enters the system—such as from running multiple heavy appliances simultaneously—the tank cannot process the waste effectively. This causes solids to overflow into the drain field, leading to clogs and structural strain.

What are the most common causes of septic tank damage?2026-05-12T10:13:43-06:00

The four primary causes of septic tank damage include blockages (often from solids or tree roots), improper maintenance (skipping inspections and pumping), system overuse (exceeding hydraulic capacity), and poor installation (incorrect sizing or non-compliance with regulations).

What are the best conventional septic installation options for homes in central Oklahoma?2026-05-14T08:55:23-06:00

The most reliable conventional systems incorporate:

  • High-quality concrete or poly septic tanks
  • Properly engineered lateral lines sized to the soil profile
  • Accurate elevation and drainage design to ensure correct flow

Red Dirt Septic’s systems exceed DEQ specifications and prioritize long-term system reliability.

What are the benefits of aerobic septic installation for homes in central Oklahoma?2026-05-14T08:56:24-06:00

Aerobic systems deliver advanced wastewater treatment, flexible placement options, and the ability to function effectively in clay-dense soils or smaller lots where conventional systems cannot be approved.

Homeowners benefit from enhanced treatment performance and predictable compliance. Both aerobic and conventional systems can produce odors only when they are failing. Conventional systems generally have a longer service life when installed in suitable soils.
