During the construction of water supply systems and water supply wells used with precast concrete.
Water wells are designed to accommodate the water supply valve and its management, performance of repairs and maintenance.
Round observation wells used for water supply networks and a diameter of 50 - 600 mm.
Working height of 1500, 1800, 2100 and 2700mm diameter rings consisting of 1000.1500, 2000 mm.

Observation wells installed at the junction, changing direction, slope and diameter pipelines. By appointment wells are classified into:
a) linear;
b) turning;
c) node with one accession;
c) node with two accession.
In the section of the direct distance between manholes in sewer systems installed, depending on the diameter of pipes.

Round observation wells with an internal diameter of 1000 mm chamber installed on the pipelines to 600mm.
On pipelines with a diameter of 700, 800-1000 and 1200 mm diameter circular wells respectively 1250, 1500, 2000 mm.
The internal diameter of 700 mm neck.

Working camera inspection of sewer manholes height 900, 1200, 1500, 1800, 2100 mm in diameter consisting of rings 1000, 1500, and 2000 mm with seam compound.
To pass the effluent discharge in the bottom, to arrange an open tray.
The minimum depth of wells in the tray is the largest diameter pipe attached to the shaft.
Breakout well differ from linear only tray that has a curved shape on a smooth curve with a minimum radius equal to two-to three pipe diameters.
Node well is different from the linear presence node connected trays, consisting of not more than three summed pipes.
