The first manhole for a building sewer must be no further than what distance from the building?
50m
75m
100m
125m
The correct answer is: 75m
The first manhole for a building sewer must be no further than 75m from the building. This is because building sewers are responsible for collecting and transporting wastewater from individual buildings to the public sewer system or treatment plant. Having the first manhole within 75m of the building ensures efficient and effective collection and transportation of wastewater. Options A, C, and D are incorrect because they are too far away and would likely result in more difficult maintenance and potential for clogging or blockages in the sewer line.
