What do you need to know to empty a pit?

A septic tank is a tank in which the wastewater generated in that home or facility is collected. These collected wastewater are transported to an authorized manager or treatment plant.

It is a limited space where the concentration of decomposing organic waste can generate gases that are harmful to health. Therefore, periodic cleaning and emptying, carried out by qualified and experienced personnel, is essential.

Before hiring a septic tank emptying, several aspects of this job should be considered.

First of all, it is a service that must be contracted to specialized companies, with the corresponding authorizations. Emptying a septic tank is a high-risk job.

The gases generated by the decomposition of organic waste, especially large quantities of methane gas, represent a real danger if prevention and appropriate safety measures are not taken.

In addition, a series of effective resources are needed for this work, such as tank trucks with water delivery pumps and tank, suction handles…

How to empty a septic tank

Companies authorized to empty a septic tank have vehicles adapted for this service and have a professional team highly prepared for this service.

The process of emptying a septic tank follows the following steps:

Step 1 – Open the lid

The septic tank lid is opened with appropriate prevention. The gases produced inside can be very harmful to health.

Step 2 – Preparation of the vacuum pump

The positioning of the vacuum pump must be carried out in the initial stages at the level of the residual water. This way it will vacuum the top layer first.

Step 3 – Submerge the pump

As the septic pump emptying process continues, the vacuum pump must be submerged. However, it is recommended not to reach the bottom so as not to eliminate that last remaining layer.

Step 4 – Filling the septic tank

Using a hose of clear water, the septic tank is progressively filled. At the same time, it is used for waste disposal.

Step 5 – Completed sludge aspiration

When more or less 80% of the sludge has been vacuumed, it is advisable to leave the rest so that purification can be carried out after a while. The remaining space must be filled with clean water.

Why should you empty a septic tank?

The main reason why it is important to empty a septic tank is environmental and economic, since if it is not maintained as indicated in the Water regulations of Royal Decree 1/2001, the fines will be high. Regular cleaning prevents contamination of the soil and groundwater. With this action, we help protect local ecosystems and prevent diseases from spreading through the water.

But also, if we do not empty a septic tank correctly, it ends up affecting the drainage systems of the home or the connected facilities.

The consequences of not emptying a septic tank or signs that it is urgent to request this service include unpleasant odors, slow drainage on your property, or even stagnant water around the tank because it has reached the maximum level of capacity.

For this reason, it is also advisable to empty the septic tank when the sludge is half of the available space and not wait until the last moment.
