The Weir

The weir is the part of the hydroelectric system that diverts water from the stream.  It is a section of steel rebar reinforced concrete that sits across the bed of the river.  The headrace transports water from the weir to the settling tank.  We poured the weir last Friday and we are now waiting for the concrete to cure before removing the formwork.

  1. Great work on a worthwhile project!

    Thanks for the effective descriptions and photos. My ES 22 students at Dartmouth visited your site to learn about your project, then do a homework problem on it.

    Best wishes in wrapping up your work!
