Construction of a water main from Glubochitsky Street to Vladimirskaya Street. The main part of a waterway is laid by a method of mechanized shield driving by PS 2.15 shield. The water main consists of D 900 mm steel pipes that are laid in a D 1780 mm tunnel. The average driving depth - 15 m. Taking into account the hydro-geological conditions of water main construction, a part of water main was laid with the application of microtunnelling technology.
