Abstract

The City of Bowling Green, OH operates a water distribution system that delivers high quality water. The system operates optimally in a grid system; larger, “trunk water mains,” are installed in a grid pattern on the outer limits of the system with smaller lines branching from the larger lines. Almost all the residential, industrial, and commercial areas in Bowling Green were originally limited to the west side of I-75. However over the past few decades, these areas grew on the east side of I-75. Two 24” water mains crossed underneath I-75 at the central and south part of the city to provide water to the east side. These limit development in the north eastern section and subject the WWTP (located in that part) to an undue risk if any damage occurs in the central trunk. The installation of a 16” waterline underneath I-75 at the northern end will ensure fire protection for the existing industry and supply a second water source to the WWTP. Four construction methods are examined to cross the interstate with a new waterline: open cut with detouring traffic, postponing the installation until resurfacing the interstate to install the line by open cut, horizontal directional drilling, and auger boring. This paper examines the design and construction cost of the four potential methods of construction to install a 16” waterline underneath I-75.
