Pipe renewal with large expansion with pipe bursting

In the far east of Poland, in the Lublin province, you can find the city of Pulawy with around 48.000 inhabitants. Since its first documented reference as a settlement in 1626, Pulawy has witnessed an alternating history: In the 17th century, families of the high nobility built a magnificent large castle in a huge park and a hundred years later the town became an important part of political and cultural life. Even an important museum with royal jewels, collections of paintings and memorabilia of famous personalities was founded here in the castle in 1801 and today these precious collections are located in Krakau. During the third partition of Poland the town fell to Prussia, shortly afterwards it became part of the Duchy of Warsaw, eight years later part of Congress Poland, and another fifteen years later it fell under Russian and Ukrainian sovereignty. In 1906 Pulawy received municipal rights; since the First World War it has belonged within the Polish borders. Find out more
