What Is a Septic Tank?

A septic tank is an underground watertight tank that collects and stores wastewater from a home or business. The wastewater flows into the tank, where it is separated into three layers: solids, scum, and liquids. As time passes, the solid waste accumulates in the bottom of the tank while the liquid layer rises to the top.

Where Should It Be Located?

The septic tank should be located at least three meters away from any buildings or water sources. It should also be situated on a flat, well-drained surface and surrounded by a buffer zone of grassland to prevent contamination of the surrounding environment. Proper positioning will ensure that your tank works properly and efficiently for years to come.

The Steps Involved in Emptying a Septic Tank:

Before emptying a septic tank, it is important that you have the right equipment and safety gear to ensure a safe and successful evacuation. First, make sure that the ground around your tank is firm so that heavy machinery can access the area without damaging or shifting the soil. Once this has been done, check for any blockages in your pipes and remove them if necessary. Finally, contact a local septic services company who will come out with their specialist equipment and safely evacuate your tank.

How Often Should You Empty a Septic Tank?

The frequency of emptying can vary depending on several factors such as usage levels, size of your household/business, and amount of wastewater produced. Generally speaking though, most tanks should be emptied every two to five years for households with up to four occupants or businesses with less than fifty employees. If you have more people living in your home or more employees, you may need to empty the tank more often.

It is also important to note that if you see signs of a problem such as bad odors or slow drainage, you should contact a professional septic services company immediately. They will be able to inspect your system and determine whether it needs emptying sooner than expected.

What Needs To Be Done Before The Emptying?

Before having your tank emptied, make sure all wastewater-producing activities are stopped for at least 24 hours before the evacuation process begins. This will help ensure that any solids have had time to settle at the bottom of the tank so they can be easily removed during the emptying process. 

Cost to Empty a Septic Tank:

The cost of emptying a septic tank can vary depending on the size and location of your tank as well as any additional services required. Generally, you should expect to pay anywhere between £200 – £400 for an average-sized residential tank in the UK.

Tips for Keeping Your Septic Tank in Good Condition:

To ensure that your tank is able to work efficiently for years to come, there are a few things you can do. First and foremost, avoid flushing anything down the toilet other than human waste and toilet paper. Additionally, be sure not to overload the system with too much water from washing machines or showers as this can cause blockages or slow drainage. Finally, it is best to have your tank inspected by a professional every couple of years so any issues can be identified and dealt with quickly.

By following these simple steps and ensuring that your septic tank is emptied regularly, you will significantly reduce the risk of costly repairs or replacements in the future!
