  • Removing solids . Servicing TOPAS A with your own hands involves removing various deposits. Residues of food and garbage are carried in by drains.
  • Rinsing with running water . Should be carried out at least once a year. Maintenance of a septic tank in St. Petersburg must necessarily include cleaning of the receiving compartment and tanks, regardless of the model of private sewerage.
  • Replacing membranes in the compressor . Maintenance of the TOPAS autonomous sewer system will not be effective if the filtration units are not replaced in a timely manner.
  • Flushing the system with boiling water . This will prevent grease deposits and potential blockages from forming in the drain compartment.

Criteria for choosing a Topas septic tank

When using any equipment, you must follow the operating rules.
Proper selection of a biorefinery station model involves purchasing a unit that is suitable for specific operating conditions in all respects:

  1. Selection based on performance
    . This parameter determines whether the installation can cope with the processing of wastewater and sewage. For example, the “youngest” septic tank in the model range, Topas 5, is capable of serving a family of no more than 5 people. Station Topas 10 easily copes with wastewater from a building where no more than 10 residents permanently live and enjoy the benefits of civilization.

    When choosing a model, you need to take into account that in the future the family may be replenished with new members or guests will arrive. Therefore, for a house in which 5 people live, it is better to install a Topas 8 septic tank.

  2. Choice based on design features
    . An important point that you should pay attention to is the geological conditions in the suburban area. The Topas septic tank, which is easy to maintain, can be installed on different types of soil, but when the water layers are located at shallow depths, preference should be given to the model marked “PR” (read: “Installing a Topas septic tank with your own hands - connecting according to a proven scheme "). It is equipped with a pump designed to force the movement of purified water.


If the external section of the sewer pipeline is laid at great depth, the choice should be made in favor of the Long modification (in which the manufacturer has provided for a deep insertion of supply pipes).

To flush the septic tank with boiling water, it is enough to pour a couple of liters of water into the toilet. The frequency of the procedure is once every seven to ten days.

  • Replacing aerators . Maintenance of TOPAS 5 or another septic tank model involves installing new mixers every 10-12 years.

The presence of the letters PR in the marking of equipment indicates the presence of pumps in it that perform PR forced pumping of liquid, the need for which arises due to certain features of the installation site.

If the marking is accompanied by the word LONG, this means that the body is elongated in the vertical or horizontal direction.

Features of maintenance of the TOPAS septic tank

What is a Topas septic tank?

The Topas biological treatment system is equipped with a plastic housing with stiffeners.
It is divided inside into several chambers. Wastewater, successively passing through the compartments, is subjected to mechanical sedimentation and biological treatment (for this, aerobic microorganisms are used in an oxygen-saturated environment). The manufacturer of Topas stations equips them with compressors and aerators - these devices are used to create the most favorable conditions for the life of aerobe bacteria, enriching their habitat with oxygen. To move wastewater inside the installation, pumps and airlifts operate.

How to carry out TOPAS maintenance yourself

Owners of autonomous sewage systems fully enjoy urban comfort in their country house, cottage or country house. But at the same time, they should not forget about timely maintenance of the treatment facility. Compared to other treatment systems, the TOPAS installation boasts ease of operation and ease of maintenance.

The design of our treatment plant is designed in such a way that it makes it easy for even a non-specialist to carry out maintenance; the owner can carry out all the work himself. We recommend maintenance every three months. If the owners do not live in the house permanently, you can carry out maintenance less frequently, once every six months, but you cannot delay this, otherwise a lot of waste sludge may accumulate.

First of all, you need to conduct a visual diagnosis. You need to open the installation and fill a jar with water and leave it for 20-30 minutes to assess the sludge concentration. If the sludge concentration is 50% or more, then it is necessary to pump out 1/3 of the sludge settling chamber (for TOPAS 5 this is 70 cm). If the sludge concentration is less than 50%, then pump out ¼ of the chamber (for TOPAS 5 this is 50 cm).

Next, you need to turn off “TOPAS” with the switch in the compressor compartment for 20 minutes so that the waste sludge settles to the bottom of the installation. Then, by releasing the clamp, remove the plug on the sludge stabilizer pump hose. To pump out sludge, it is necessary that the installation operates in the first cycle - in the receiving chamber, the float switch must be in the raised position. We substitute a bucket and pump out the sludge. The sludge can be pumped into a compost pit. After humus, it will serve as a wonderful fertilizer on the site.

The installation should not remain empty so that it is not pushed to the surface by groundwater. It is necessary to fill in as much clean water as was pumped out.

Now you need to clean the pumps. Let's start with the main pump in the receiving chamber. Remove the hose from the airlift fitting and unfasten it from the support attached to the wall of the chamber. We remove the pump from the installation. Similarly, we remove the remaining pumps (2 pumps in the aeration tank chamber and the sludge settling pump) and the hair catcher.

We wash the pumps and filter with a hose or mini-wash. We also wash the installation walls and lids from plaque.

Using a sieve, non-recyclable waste is removed. When operating TOPAS, you must not throw construction waste, hygiene bags, cigarette filters, or films from cigarette packs into the sewer system - this will lead to clogging of the installation.

Finally, you need to clean the nozzles with a regular sewing needle or wire.

With just a little attention and care, you will appreciate how the TOPAS treatment plant will become a real indispensable assistant for you in your everyday life for many years!
