About this file
This document appears to be a set of design drawings and specifications related to a federal contract opportunity to replace a deficient water treatment system at Wrangell-St. Elias National Park and Preserve (WRST).
The drawings provide details on the proposed upgrades to the water and sewer utilities, including the installation of a 1,000-gallon septic tank, a leach field, and associated piping and infrastructure. Key details include the pipe sizes, lengths, slopes, and depths, as well as notes on construction requirements and documentation. The related federal contract opportunity is Solicitation Number 140P2024R0034 for the "WRST 248940 - Replace Deficient Visitor Center / Headquarters Water Treatment System", issued by the Department of the Interior National Park Service. The drawings appear to provide technical specifications in support of this solicitation.

DOCUMENT FINDINGS, AND REPORT TO ENGINEER.
2. THE PROPOSED LEACH FIELD SHALL COVER A MINIMUM OF 270 SF.
3. CONTRACTOR SHALL DOCUMENT INSTALLATION OF PROPOSED LEACH
FIELD AND SEWER PIPE MODIFICATIONS WITH AS-BUILT NOTES,
ELEVATIONS, AND PHOTOS. DOCUMENTATION SHALL BE DELIVERED TO
ENGINEER ONCE CONSTRUCTION IS COMPLETE FOR RECORD
DRAWINGS.
4. THE CAPACITY OF EXISTING LEACH FIELD IS 511 GPD PER 2013 DESIGN

COVER OVER SEWER SERVICE FOR AS
MUCH OF THE RUN AS POSSIBLE. RECORD
INVERT ELEVATIONS AND DEPTH OF COVER
AT HORIZONTAL AND VERTICAL CHANGES.
