Square waste sumps and tanks

Our plastic square sumps and tanks provide a practical solution for wastewater management. You can choose from a range of sizes, but we can also manufacture a sump to your requirements.

The square-shaped plastic septic tank is a three-chamber tank for holding sewage water. We offer these septic tanks in 4 different sizes, ideal for households of 5, 8, 10 or 12 people. The tank is manufactured by welding propylene plates and wall elements and is available in self-supporting or concrete-lined versions. For mounting, we recommend a concrete base plate, which provides stable and reliable support.

Number of EO = number of equivalent persons. I.e. For how many people a septic tank of a given capacity is optimal.

A leakage test report is included in the delivery. The septic tanks can be ordered with plastic lids made of UV-resistant material. The material used is resistant to the effects of moisture and the aggressive environment of wastewater. The inlet and outlet pipes can be adapted to the dimensions required. If necessary, the manufacture of sumps in atypical dimensions can be arranged. Wastewater sumps can also be found in oval and round shapes.

Where are square sumps and tanks used

Square waste sumps are used in homes and other properties that do not have the option of central sewage disposal. They are also used where properties are experiencing difficulties in obtaining permits to discharge sewage into groundwater. However, remember to act in accordance with current legislation, in a manner approved by the relevant authority for the site.
