Abstract

There has been a growing concern over the rate of deterioration of wastewater collection and water distribution systems in the United States. The ever-growing need for rehabilitation and replacement of these systems has led to the birth of a research program by the United States Environmental Protection Agency focused on addressing the water infrastructure needs. This program-Innovation and Research for Water Infrastructure for the 21st Century-lays emphasis on research focused on system rehabilitation. There is a marked change in the way that the public view the environmental needs with ‘green’ becoming ‘the new gold’. Man has been blamed, and rightfully so, for the global warming evidenced since the mid-20th century. Environmental impact and contribution assessment has now become a necessity, especially for major projects, both in rural and urban environments. It is with this in mind that this study was carried out; its main purpose being to compare the environmental impact and contribution of both horizontal directional drilling (HDD) and open-cut construction methods during a pressurized water mains installation process. The study employed the use of the Environmental Value Engineering (EVE) methodology which, unlike any other environmental assessment method, accounts for the environmental inputs, fuel energy inputs, goods, and services to the alternatives competing for similar resources.
