Water Intake At New Illinois Power Plant Designed for Variable Flows

The intake system that will draw cooling makeup water from the Kaskaskia River for the $250-million Holland energy plant in Shelby County, Illinois, was designed to balance construction cost imperatives against the river’s variable flow, regulatory requirements and the owner’s operating preferences. The result is a state-of-the-art vital element for the gas-fired, combined cycle plant. As more and more closed-cycle plants are proposed, the concepts that Parsons applied along the Kaskaskia River may provide a good starting point on the drawing boards.

Pumping System Helps Town Bring New Development Up to Code

When a Leicester, Mass., developer planned a subdivision of 16 houses at the same elevation as the town’s water tower, he was faced with the problem of how to provide minimum water pressure mandated by the state. He had read about the use of a Goulds Aquavar pump control system in high-rise commercial buildings, and the idea of a variable-speed system appealed to him. He thought a pressure-demand system might do the job cost effectively.
