Water is the lifeblood of electrical power plants, whether they are water-cooled steam plants or turbine-spinning hydroelectric installations. Regardless of how the facility generates electricity, there is a growing awareness that each power plant is part of its own, unique industrial watershed—drawing water from the environment, altering its contents and temperature, releasing some to the atmosphere as steam, and returning the rest to receiving waters.
More long-term data is available than ever before to help wastewater designers and engineers make accurate estimates of up-front costs and life-cycle costs associated with pressure sewer systems. In addition, incorporating extended equipment warranties into project evaluations, specifications, and contract documents is a pivotal tool to help decision makers reveal the true, long-term equipment costs of various sewer system technologies.
