How much does it cost to empty a septic tank? How often should it be emptied, and what documents might the authorities ask you to provide? We've put together a practical guide to help you find the answers.
How Often Should You Empty a Septic Tank or Cesspool?
How often a septic tank or cesspool needs to be emptied depends on two main factors: the capacity of the tank and how intensively it is used.
A vacuum tanker may need to visit a property occupied all year round several times a year, while a single collection per season may be sufficient for a holiday cottage used only occasionally.
It's important to remember that the handling and disposal of wastewater are subject to legal requirements under the Czech Water Act (Act No. 254/2001 Coll.). Allowing a tank to overflow can contaminate the surrounding soil or groundwater and may result in substantial fines.
Important: Keep Proof of Cesspool Emptying
Czech legislation requires property owners to demonstrate that wastewater collected in a cesspool is disposed of properly.
The relevant authorities may ask you to provide records of cesspool or septic tank emptying covering the previous two calendar years, where applicable. Records of wastewater removal should clearly state the volume removed and identify the authorised company that carried out the service. To help demonstrate compliance, keep all receipts and service records provided by your wastewater removal contractor.
How Much Does It Cost to Empty a Septic Tank, Cesspool or Holding Tank? (Price Guide)
Wondering how much it costs to empty a septic tank? The total price typically consists of several elements: the volume of wastewater removed, the wastewater treatment fee, and the cost of transporting the wastewater to the treatment plant and back.
Specialist service providers generally calculate their prices based on a fixed collection charge and the distance travelled by the vacuum tanker. As we operate throughout the Czech Republic, the final price depends partly on the distance our equipment needs to travel from our main depots.

How to Clean an Old Septic Tank and Keep It in Good Condition
In addition to pumping out liquid waste, it may sometimes be necessary to remove sludge that has accumulated at the bottom of the tank.
If you're wondering how to clean an old septic tank, biological products containing specialised enzymes and bacteria may help break down certain organic waste and reduce unpleasant odours. However, their effectiveness depends on the type and condition of the tank, and they should not be considered a substitute for emptying it when necessary. If significant deposits have built up, mechanical cleaning using high-pressure water may be required.
