Apart from the pressure tubes of hydropower plants the most common case
is probably sewer pipes. For general transport pipelines cutting them
into rock is rare due to the high costs. Hydropower penstocks are an
exception mostly due to the high volume high pressure combination and
sewage due to the space constraints in urban environments.
