Sewerage self-financing construction

Person except sewer manager receives approval from sewer manager and performs construction about sewer facility on public roads at own expense.
For example, if three houses are built where one existing house was located, three mounting pipes will be required, but in most cases, two of them will be self-financing (new construction), and one will be existing. Use the mounting pipe. If you change the position of the existing mounting pipe due to the layout of the building, this will also be your own expense (removal / new construction).
