52.127 COVER AND ALIGNMENT.
The cover over the crown of the building connection shall be at least four feet to afford protection from frost action.

This list has been excerpted directly from the Standard Specifications to give an overview of the type of information required for a sewer extension. Additional required information can be found in the Standard Specifications noted above:
- Design sanitary flow calculations prepared by a professional civil engineer currently registered in the State of New Hampshire.
- The plans shall show manholes placed at the end of each sewer line, at all pipe intersections and at all changes in alignment. Desirable spacing of manholes shall be 300 feet.
- The plans shall show all proposed sewers at sufficient depth to receive sewage from below basement floors and to preclude freezing.
- The minimum depth of cover over the sewer in roadways shall be 6 feet and for cross-country shall be 4 feet.
- Sewers shall be uniformly graded between manholes and the size, slope, type of material and class of all pipes shall be shown on the profiles.
- Manholes shall be located at all changes in grade or pipe size.
- A drop entry pipe shall be provided for any sewer entering a manhole at an elevation of 24 inches or more above the manhole invert. Where the difference in elevation will be less than 24 inches, the slope of the incoming pipe sewer shall be adjusted to meet the manhole invert elevation.
- Profiles shall indicate all manholes. All pipe invert and rim elevations shall be shown.
- The locations and depth of other existing or proposed underground utilities shall be shown on the plans in order to avoid conflicts during construction.
