Septic tank cleaning
Before getting started with septic tank cleaning, do you know what a septic tank is and how it works? If yes, that’s great. But in case you are not much familiar with a septic tank, we have created a quick overview of a septic tank and its working procedure.
A septic tank is a large container that is placed under the ground. It is used for the purpose of treating wastewater that flows out of the house. It is typically made up of fiberglass, plastic, or concrete. Septic tank is used where sewerage or wastewater management is not available. Most commonly used at onsite areas.
How does a septic tank work?
The Septic tank separates the sewage and wastewater into different chambers. After a short period of time, sludge and scum layers build up within the tank.
It usually consists of two compartments. Higher density solids settle down at the bottom and the liquid waste passes to the other compartment. Solids get decomposed by anaerobic digestion and as a result, produce sludge. This sludge reduces the active volume of the septic tank and therefore there is a need to clean out the tank.
It’s important that the septic tank is cleaned on a regular basis in order to get rid of the sludge and scum buildup. Without cleaning the tank, the system will become inefficient. It will not effectively treat the wastewater that flows through it.
Septic tank cleaning:
We have got enough introduction of septic tank ant its working procedure. Now let us talk about septic tank cleaning. Cleaning a septic tank is a regular process that’s done after every two or three years. However, a regular inspection is highly recommended in order to keep your tank working efficiently. Inspection can be done by checking the scum and sludge layers of the tank. If the scum layer gets into 6-8 inches of the outlet pipe, then the system needs to be cleaned. Similarly, when the lower sludge layer gets into 12 inches of the outlet pipe, the system needs to be pumped out. However, inspecting your tank is not an easy job. If you are unable to inspect your tank, ask for a professional inspector. He will check for any leakage or clogging from the tank and then inspect the scum and sludge layers.

Here at UAE Septic Tank Cleaners, we have created a quick 10 step guide regarding septic tank cleaning:
Assessing the septic tank:
First of all the process begins with assessing the septic tank. The professional team will assess your tank and do the necessary inspections, whether the tank needs to be cleaned or not. They will check for any leakage from the tank and also check for any clogging. Then they will inspect the scum and sludge layers. If the scum layer is under 6-8 inches and the lower sludge layer is under 12 inches from the basic outlet pipe, the tank needs to be cleaned.
After the inspection is done and the tank needs to be cleaned, the entire tank is disinfected. Particular chemicals like peracetic acid have been used to disinfect the tank. Adding 1 g L(-1) of peracetic acid to wastewater is a highly effective way of disinfection. It will destroy all the microorganisms and completely remove the slurry smell from wastewater.
Afterward, with the help of a sludge pump, all the sludge and scum have been pumped out. A large hose has been inserted into the tank from the manhole. All the waste is pumped out in a tanker truck. The stirring technique has been used to break the solid waste particles and mix them in liquid. So that the pumping process becomes easy. Now the whole tank is empty and ready for further steps of cleaning.
4. Dirt removal:
Using high precision equipment, all the sediments, dirt, stains, and fungus have been removed.
5.Tank cleaning with pressure:
In the next step, a high-pressure jet is used to clean off the whole tank. The walls, ceiling, and floor of the sewage tank have been washed out with pressure.
6. Vacuum cleaning:
Step 5 is followed by the vacuum cleaning technique. All the remaining dirt has been sucked out with the help of a vacuum.
7. Tank disinfection:
Afterward, an anti-bacterial spray or liquid bleach is used to completely disinfect the tank.
8. Ultraviolet rays:
Ultra Violet or UV radiations are applied on tank and the surroundings in order to get rid of any harmful bacteria.
Finally, the tank is completely drained and left for drying. After some time drying your tank will be ready to use.
10. Tank is cleaned:
That’s it! Use your tank, it’s cleaned and ready to use. The cleaning has been done now but maintenance is a must for the efficient running of the tank. In order to keep running your tank efficiently, do the regular inspections and checkups of the tank. On average, an inspection after 2 years or so is a good deal. But if your tank has been installed with mechanical tools such as an alarm, electric switch, pump, etc. Your tank needs to be inspected every year. For maintenance of the tank, avoid using much water, avoid putting solid waste into the tank. Moreover, direct rainwater away from the drain field. Also, avoid putting chemicals down into the drains.
