The PS extension is used to extend the MSR and MSO manhole. It is used in household sewage treatment plants with a rotary tank equipped with a distribution well. It allows for an increase in the depth of the tank installation. It cannot be applied directly to the tank, but only to the tank well. The extension does not include a cover.
The extension is made of high-quality polyethylene. It is resistant to adverse external conditions. It does not corrode when exposed to UV and is not affected by chemicals, including corrosive sewage. It is also durable against mechanical damage.
