Knowing the Cost to Empty a Septic Tank

This article will provide you helpful information about emptying a septic tank, including the cost, materials, labor and turnaround time of this home improvement project.

Project Basic

If you’re living in a rural location, you’ll consider a septic tank as part of your necessities, but people living in the city or suburban areas mostly do not pay attention to their sewer systems. What they’re not aware of is that, if there is no main sewage in your house, you’ll be required to install a septic tank for baths, toilets, and dishwashers in draining. 

But these tanks need emptying at least once a year. In most cases, contractors’ drives tankers onto your property, which will need a cleared access between the septic tank and the parking area. The termination of mud or emptying service for septic tanks offered to customers usually engages the termination and treatment of around 1000 gallons of mud.

Normally, backwashing is part of the tank emptying process to remove the remaining solid particles. This emptying service can be done in a single time or more often as part of a regular maintenance in the contract.

Knowing More about the Job

Septic tanks use an outlet pipe to run into a drainage field or “absorbing well”. An absorbing well is a network of holed or slotted pipes which allows the wastewater to pass through slowly into the ground without polluting it.

The septic tank separates the waste into “dross”, “separated wastewater” and “mud”. The separated wastewater runs in the absorbing well system which causes more solid phooey stuff to remain in the tank, this is why septic tanks need to be emptied regularly.

Failure to empty your septic tank regularly will result in a toilet starting to take longer flushing and worse, getting a stinky waste back at your home! This pollutant can then get into the soak-away system and pooling above the ground and create a disgusting smell and pollute your local water sources.

Wondering about the cost to empty a septic tank, there’s a major effect that you can imagine with the size of your tank. The bigger your septic tank, the more work to empty it and flush the solids. Bear in mind that when choosing a tank, it’s not just a toilet and bathroom water, but water from washing machines, sinks and dishwashers too. Meaning, you need a tank with adequate capacity.

Small size septic tanks are not pricey to install as they can often be above ground and no excavation required, plus the tank itself is not expensive, but that doesn’t mean they don’t require regular emptying. This can be expensive over the tank’s life.

Larger tanks may be pricey in both installation and purchasing because they are mostly underground, but are cheaper over the long term. Another benefit of a large septic tank is that it’s able to be emptied less often because of the filtered water waste from the absorbing well. Only, if the septic tank is installed properly and emptied regularly.

The Cost to Empty a Septic Tank

Special equipment from the septic tank specialist will be used to empty the tank and dispose of its contents safely. They usually charge around £80-£300 per empty, depending on the size and time it may take to clean it. As per the size, this will usually be done once a year.

What is a Septic Tank?

A septic tank is a chambered tank system where waste property flows which in later time solid particles forming into mud-like substance at the bottom of the tank. Bacteria naturally breaks down this substance while the remaining liquid is being drained in the absorbing well.
