Cesspools are drainless tanks used to capture water from waste. Cesspools are used for family houses, cottages, holiday homes and wherever it is not possible to connect to the municipal sewerage system. This is an ideal option for places where it is not possible to have a septic tank.

Wastewater accumulates in the sump, and because it has no outlet, it is necessary to have its contents transported by a faecal truck to a wastewater treatment plant as needed.

The operation of the septic tank is also associated with the operator’s obligations – to ensure access for the faecal truck when removing wastewater and to prevent leakage of sewage from the septic tank into the surroundings.

As standard, the sumps are supplied with a Ø 800 mm inlet chimney and two covers, the inner cover of which is odour-proof. Ø 160 inlet from HT pipe.


We make the double wash basins in two variants.

  • Cylindrical
  • Rectangular

For each of these variants we offer 3 types of design:

  • Self-supporting 

Designed to be excavated on a concrete slab base, backfilled with soil, sloping.

  • Unsupported

Designed to be excavated on a concrete slab base, concreted into a running surface or in areas with groundwater or clay subsoil.

  • Double-walled

The design combines the advantages of plastic and concrete. At the same time, it is also a carrier for the reinforcement of the future concrete in the intermediate slab. The plastic walls perfectly protect the concrete structure against the aggressiveness of sewage and groundwater.
The tank thus acquires the static properties of concrete tanks – load-bearing capacity and resistance to soil pressure and loads from rolling stock.
