"Zawartość Zbiornik" should be "Zawartość zbiornika".
"Zawartość rury" should be "Zawartość rurociągu".
"Podziemny rurociąg" should be "Rura podziemna".
"pipeline" translates to "rurociąg" and "pipe" to "rura", and the two have been confused. Additionally, there is a lack of the genitive form of "zbiornik".
