Although these terms are sometimes used interchangeably in everyday language, they refer to different types of wastewater systems. Their design, operation and maintenance requirements vary. In our previous article, we explained how much wastewater tank emptying costs and how often tanks need to be emptied. This time, we focus on the differences between a sealed holding tank and a septic tank, the advantages of each option, and how to maintain them properly.
Holding Tank (Cesspool): A Sealed Solution for Occasional Use
Let's start with the simplest option. In the Czech context, the terms jímka and žumpa refer to the same type of installation: a sealed underground holding tank with no outlet or filtration system. Its sole purpose is to collect and store wastewater until it can be removed.
-
How it works: Wastewater from toilets, bathrooms and kitchens flows directly into the tank. Once it reaches the appropriate level, a vacuum tanker must be called to empty it.
-
Advantages: Relatively low installation costs, straightforward operation and no wastewater discharge from the tank itself. Construction and other applicable requirements still need to be checked for the specific property.
-
Disadvantages: Permanently occupied homes may require frequent emptying, resulting in higher long-term operating costs.
💡 OUR TIP: If you have a cottage or another property used occasionally, or a smaller holding tank with a capacity of up to 200 litres, our specialist Fresh 24 express service can provide a fast and convenient emptying solution. If your tank has a larger capacity, contact us for a tailored quotation.
Septic Tank: A Multi-Chamber System for Initial Wastewater Treatment
What is the practical difference between a holding tank and a septic tank? The main distinction is that a holding tank stores wastewater, whereas a septic tank provides initial treatment before the wastewater moves to a further treatment or disposal stage.
-
How it works: A septic tank typically has two or three chambers. Heavier solids settle in the first chamber, while bacteria break down some of the organic matter. Wastewater then flows through the subsequent chamber or chambers. A further treatment stage, such as a suitable soil or sand filter, may be installed downstream. Depending on the system design and the required permits, the treated wastewater may then be discharged or infiltrated into the ground.
-
Advantages: A properly designed septic system can require less frequent removal of accumulated sludge than a sealed holding tank. The actual emptying interval depends on the tank's design, capacity and usage.
-
Disadvantages: Installation costs are generally higher, and the approval process may be more complex. Under Czech legislation, the applicable requirements depend on the type of installation and the proposed wastewater treatment and discharge arrangements.

Care and Maintenance: How to Keep Holding Tanks and Septic Systems in Good Condition
Proper maintenance helps extend the service life of your wastewater system and reduce the risk of unpleasant odours and failures. Summer temperatures and increased usage can put additional strain on the system.
1. Support Beneficial Bacteria
Bacterial products designed for wastewater systems may help support biological activity in septic tanks when used according to the manufacturer's instructions. However, they do not replace regular inspections, sludge removal or other required maintenance. Their effectiveness also depends on the system and the product used.
2. Be Careful with Household Chemicals
Avoid disposing of paint, solvents and other hazardous substances down household drains. Excessive amounts of chlorine-based disinfectants, acids and other harsh cleaning products may disrupt the biological processes in septic systems. Use cleaning products responsibly and follow the manufacturer's instructions.
3. Do Not Neglect Regular Inspections and Servicing
Check the liquid level in your holding tank regularly and arrange emptying before it becomes full. Septic tanks should also be inspected and serviced according to their design and operating requirements. Leaks and overflows can contaminate the surrounding environment and may lead to penalties under applicable regulations.
