headrace
Definitions
from The American Heritage® Dictionary of the English Language, 4th Edition
- noun A watercourse that feeds water into a mill, water wheel, or turbine.
Examples
-
In the configuration finally adopted, water to be pumped is taken from the headrace canal with a separate sedimentation arrangement in the forebay so that there are still fewer suspended particles as compared to water supplied to the turbine.
-
Other improvements that will be started in the coming year include repairing and restoring the mill's headrace, which guides and controls water flow from the river to the mill, masonry repairs to the foundation walls, repainting the cupolas of the Slater and Wilkinson mills and replacing the Slater Mill's 1929 fire suppression system.
Note
The word 'headrace' is a compound of 'head' (uppermost part) plus 'race' (a channel leading water to where it can provide power).
