When to clean a septic tank
The cleanliness of a septic tank will depend on many variables, such as its size, frequency of use, and the maintenance that has been applied to it.
Preventive service is more advisable than acting when unpleasant odors, drainage problems, or stagnant water are already noticeable. For this, we suggest a visual inspection at least once every 6 months, with which it is possible to check the septic tank’s condition and plan its cleaning well.
Please also take into account the water regulations of the Royal Decree 1/2001. Among other things, it exposes the risk of a high fine if regular cleaning of the septic tank is not ensured.
Not only is it an issue that influences our comfort and well-being in the home, but proper septic tank cleaning also prevents soil and groundwater contamination. This helps to protect local ecosystems and overall health by preventing the spread of waterborne diseases.
How to clean a septic tank: Step by Step
The cleaning of the septic tank has mainly the following phases:
Preliminary phase
It is based on making a complete inspection of the septic tank, to check the level of sludge, accumulated waste, etc. In this way, we can assess the work to be carried out, the resources required, and the time needed for a complete cleaning.
Extraction phase
The next step in the cleaning of a septic tank is to remove the waste. This is done with suction elements, that allow for the removal of all accumulated sludge and waste, without damaging the walls.
Cleaning phase
With the septic tank sufficiently emptied, we can carry out the cleaning of the internal wall of the septic tank, using pressurized water.
Proper cleaning of the septic tank improves its efficiency.
Tips for proper maintenance
Good septic tank maintenance is mainly based on septic tank checks and the application of good practices to keep the septic tank in good condition for as long as possible.
Septic tank checks
- Periodically check the level of accumulated solids. It is recommended that the tank be emptied when it reaches approximately 33% of the total.
- Check the performance of the wastewater treatment system to detect any possible anomalies.
- Pay attention to any warning signs. If you notice that the drainage system is not working properly, that there is standing water, or that there is a bad smell, it is quite possible that the septic tank needs an urgent cleaning service.
Good septic tank maintenance practices.
- Avoid the use of chemicals as much as possible.
- Do not flush food scraps and wet wipes down the drain, as they do not decompose easily and generate a lot of solid waste.
- Use quality toilet paper, which is toilet paper that shreds easily and is therefore harmless to the septic tank.
- Prevent rainwater or even clean water from ending up in the septic tank, this will only lead to a much faster overloading of the space.
