About this file
This document is a set of technical drawings and details for the drainage system of the Hyrum Dam Spillway Replacement project. The drawings provide specifications for the installation of perforated and non-perforated HDPE drain pipes, gravel drains, sand filters, concrete collars, air vents, and other drainage components. Key details included are dimensions, material requirements, and installation methods for the various drainage elements. This project is part of the larger Hyrum Dam Spillway Replacement effort, which is being solicited by the U.S. Department of the Interior Bureau of Reclamation. The overall project involves construction of a new reinforced concrete spillway, riprap channels, mechanical and electrical features, and other associated infrastructure. The anticipated performance period is March 2025 through January 2029.
