Sewage and septic tank cleaning

Sewage tank cleaning in Dubai

Sewage and septic tank cleaning is the process of pumping out and emptying the tank from liquid and solid wastes. In the cleaning process, all the waste materials have been removed that are responsible for the buildup of sludge and scum layers. It is recommended to regularly inspect your tank to make sure it’s running well. On average, a tank should be inspected every 2 to 3 years and must be cleaned between 3 to 5 years. However, before diving into the topic of sewage and septic tank cleaning, lets read the science behind the sewage or septic tank.

The science of sewage and septic tank

A septic tank is a chamber usually made up of concrete, fiberglass, or plastic. It’s an underground container used for the treatment of domestic wastewater (sewage). Septic tanks can be used in areas that are not connected to a sewerage system, such as rural areas. The wastewater runs down to the septic tank through the septic drain field, which provides further treatment. But a disadvantage commonly seen is groundwater pollution may occur and can be a problem.

The term “Septic” is defined as the anaerobic bacterial environment that develops in the tank. It is responsible for the breakdown or decomposition of the solid waste material in the tank. Septic tanks can also be installed with other wastewater treatment units. Such as biofilters or aerobic systems, commonly used for artificially forced aeration.

In the settling process the solid waste settles down in the tank and liquid waste is passed to the other chamber. Similarly, anaerobic processes reduce solids and organic wastes. This process is known as primary treatment. The efficiency of primary treatment is only moderate.

The rate of accumulation of sludge is known as septage or fecal sludge. This process is faster than the rate of decomposition. Therefore, the septic tank needs to be cleaned out manually and it’s done with the help of vacuum cleaning.

Sewage and septic tank cleaning

So we discussed the science of sewage or septic tanks in detail. Now it’s time to dive deep into the main topic of sewage and septic tank cleaning. As discussed earlier that a tank must be cleaned out every 3-5 years. Beyond this, your tank will be at the risk of failure as a result of which you will face problems down the road. Besides the cleaning, it is necessary to inspect the tank on regular basis and keep records of all inspections. On average it is recommended to inspect your tank every 2-3 years. However, if your system is outfitted with mechanical components, it necessary to inspect it every year. It is recommended to hand over the task of inspecting and cleaning to a professional.

A 10 step guide by UAE Septic Tank Cleaners

Here at UAE Septic Tank Cleaners, we have created a quick 10 step guide regarding septic tank cleaning:

1. 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.

2. Disinfection:

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.

3. Pumping:

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.

9. Drying:

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.
