FIELD: hydraulic engineering construction.
SUBSTANCE: invention refers to water supply and sewerage. The well consists of at least one inlet branch located in the lower part of the well, and of at least one branch communicated with the connecting unit; the connecting unit consists of a connecting branch and a connecting element. Also the connecting branch and/or connecting element are made to turn relative to one another. The well has the first curved internal packing surface and the second curved internal connecting surface. Curved packing surfaces are more flat, than spherical surface, so radius of curve of each curved packing surface exceeds distance of each point of packing surface from its central axis.
EFFECT: simplicity and reliability of design.
