About this file
This file is a set of construction design drawings and specifications for a Temporary Wastewater Treatment Plant (WWTP) at the North Rim, prepared by HDR Engineering, Inc. (Denver, CO) dated June 2026.
The document comprises civil and structural engineering sheets detailing the temporary WWTP facility design, including site survey control and potholing plans (sheets C101-C102), overall site layout and grading plans with erosion and sediment control (sheets C103-C105), comprehensive yard piping systems with 10-inch stainless steel components (sheets C106, C401-C402, C801-C802), and civil details addressing access, utilities, erosion control, and general construction requirements (sheets C501-C506). Additional sheets cover construction staging areas, helicopter staging zones, and trailer placement (sheet G106), along with structural general notes. The drawings include survey control point tables, grading point tables, plan and profile views of yard piping, and enlarged plan views for detailed construction reference. This appears to be the design basis documentation for the installation of temporary wastewater treatment infrastructure at the North Rim location under GRCA project 318719, managed by the National Park Service.
