The remainder of the sewer will be located without the city, a considerable portion of it will be of brick.
The main sewer, from Main to Fort streets, 3412 feet, will be 24 x 36 inches. From Fort to Hawthorne streets, 5180 feet, will be 26 x 39 inches, and from the junction to the outlet, 4761 feet, w ill be 28 x 42 inches. The average depth of the main sewers will be six feet. On the north side the sewers outside of city limits to outlet below Doling’* Park, 12,175 feel in length, will be mainly pipe work of the average diameter of eighteen inches.
