The village of Lithopolis is a small, historic suburb of Columbus, OH, with a population of 1,200 but lives up to its name. Derived from Greek words, Lithopolis roughly translates to "stone city", referring to the solid layers of sandstone and lime-stone that lie beneath the village. These local rock strata recently presented a logistical challenge for the stone city last year, as it planned for a 7,200-foot line extension of its water utilities.  The line extension was needed to fee the new Grottos at Lithopolis subdivision, now in its first phase of construction.  Phase One consists of 10 houses, spaced 400 to 500 feet apart, all needing water service.  The waterline would also need to provide for Grottos'''' future lots and existing homes near the development.  The rock would pose a big obstacle, whether the village uses open-cut excavation or directional boring to install the pipe. Because the new pipeline would need to pass through the development and near other existing homes, the project would have to create as little disturbance as possible.  Another hurdle to overcome was a deep ravine near the development. With all of the factors considered, the village of Lithopolis decided that horizontal directional drilling would be the best pipe installation method for this project.
