Water main reconstruction along Maria Luiza St., Bourgas

The employer is the Ministry of Regional Development and Public Works, the main contractor is Alpine Bau Austria and Vodokanalstroy Ltd. is the subcontractor.

We constructed the city's water main - the connection between "Kamchia" and "Yasna Polyana" aqueducts - with DN600 and DN700 ductile cast iron pipes. The total length is 1900m. One of the major obstacles was the DN1000 horizontal drilling under Maria Luiza St. (34m) and under 12 railways at Vladimir Pavlov station (66m). Another peculiarity is the crossing of the "Vaya"-Sea water channel, which was done with a custom bridge work and flanged pipes DN700 with thermal insulation.
