Tangential wells

Tangential wells are installed in sewer networks of large-diameter (the diameter of the collector pipe is comparable to or greater than the pit diameter). Tangential wells perform audit and inspection functions. Their design allows equipping a well with an observation site and/or ladder.

Example 1.

A tangential well with diameter (ID) of 1600 mm, well pit height is 3750 mm, for pipeline with diameter (ID) of 2000 mm; observation site, ladder and concrete pouring chamber are located inside.

Sewerage pump station framework

A sewerage pumping station (SPS) is designed for pumping and transporting various types of liquids: industrial and household wastewater from municipal, administrative and industrial facilities, or industrial wastewater, sewage and storm water in cases where the transport of fluid by free-flow is impossible. An SPS framework is a vertical cylindrical tank, made on the basis of KORSIS or Korsis PLUS polyethylene pipes, and has a smooth inner surface through which there is no deposition and sedimentation by runoff solids. Frameworks are manufactured in the full installation package. Frameworks are an alternative to housings made of metal, concrete or fiberglass.

Example 2.

SPS framework with a diameter (ID) of 2000 mm, framework pit height 6500 mm, inputs / outputs are made of smooth and corrugated pipes. A steel service platform and ladder are installed inside, and supporting anchor bolts for the pump tube assembly are mounted.
