Mainly used in combined and household sewers. Can be performed with different types of tray, depending on the number of inputs and outputs.

Example 1.

Straight through well with diameter (OD) of 1000 mm, well pit height 1000 mm, input / output are made of smooth polyethylene pipe with diameter of 160 mm. According to SNIP 2.04.03-85 is used on straight sections (photo 1 and 2).
