Avoid unpleasant odours and breakdowns when you return from your holidays: get your septic tank ready before you leave.
If you have a property with a septic tank in Marina Alta or La Safor, it is essential that you prepare it before you leave. During the weeks you are away, the system can generate unpleasant odours, sedimentation or even leaks, especially in the hot months.
Before closing the door, take a moment to check the condition of your installation or, better still, contact a professional septic tank cleaning and maintenance service to make sure everything is in order.
According to the recommendations of the Ministry for Ecological Transition and Demographic Challenge, proper maintenance of domestic sewage treatment systems prevents polluting emissions and protects aquifers.
At Limpiezas Domingo, we have been carrying out clearances, inspections and repairs without construction work in Dénia, Jávea, Calpe and the surrounding area for over 15 years, always complying with safety and environmental regulations.
Why it is important to check the septic tank before leaving
When a septic tank is left unused for several weeks, organic waste settles and ferments, gases accumulate and natural bacteria lose their balance. This can lead to unpleasant odours, blockages and even cracks in the tank.
In addition, the heat and humidity typical of the area accelerate decomposition. That is why professional cleaning with a tanker truck before the holidays is an investment that will save you a lot of hassle when you return.
If you also take advantage of a CCTV pipe inspection, you will be able to detect invisible blockages or leaks before they turn into breakdowns.
How to prepare your septic tank step by step
1. Assess when the last cleaning was done.
Before you leave, check when you last had your septic tank emptied. If it has been more than two years, it is time to do so. Lift the lid and take a look: if you notice strong odours or a high level of sludge, call a certified professional.
2. Clean the septic tank with an authorised service provider.
The emptying must be carried out by a registered company with a tanker lorry and a permit to transport hazardous waste.
At Limpiezas Domingo, we provide:
-
Complete vacuuming of sludge and grease.
-
Pressure cleaning of interior.
-
Inspection of the condition of walls, filters, and drainage.
-
Transport to an accredited treatment plant.
In addition, you can complement the service with a repair without construction work if small cracks or leaks are detected, avoiding costly repairs in the future.
3. Add biological treatment before closing the house.
Once clean, apply natural enzyme activators to maintain bacterial balance. This will prevent the accumulation of gases and waste during your absence.
Según la Guide to domestic purification and sanitation from the Valencian Regional Government, these biological treatments help to preserve the system in an environmentally friendly and safe manner.
4. Check the ventilation and outlet pipes.
Ensure that the ventilation pipe is not blocked and that the covers and manholes close properly. Adequate ventilation prevents internal pressure that could cause cracks.
If you have a filter well, check that the drainage is working properly and that there are no roots or debris blocking the flow of water.
5. Close the stopcocks and cut off the power supply to the system (if applicable).
Close all water shut-off valves and, if your system includes an electric pump or aerator, disconnect it only if the tank is empty or at a controlled level. Otherwise, leave a minimum supply to maintain biological balance.
Signs that your septic tank needs urgent attention

Strong odours on the roof or in the garden.

Any of these symptoms indicate that it is time to contact a professional drain unblocking and pipe cleaning service such as Limpiezas Domingo.
