About this file
This is a technical drawings attachment document for a federal construction project at Cape Cod National Seashore related to replacing the Province Lands septic system. The drawings were prepared by Langan Engineering and Environmental Services, Inc., a Massachusetts-licensed engineering firm located in Boston, and are dated April 30, 2025.
The drawings include civil, utility, electrical, and landscape design plans for the project. Key technical specifications shown include a septic system designed for 250,000 daily visitors with a Title V design flow of 1,389 persons per day and a daily sewer flow of 6,945 gallons per day at 5 gallons per person. The document contains multiple plan and section views (labeled CG, CU, CE, and LP series), including site plans for a comfort station and visitor center basement, utility infrastructure details, electrical one-line diagrams for both demolition and new work phases, panelboard identification specifications, surge protective device installation details, and landscape planting details. Electrical plans show both normal and emergency power systems with specific labeling requirements (black letters on white background for normal power; white letters on red background for emergency power). Demolition and new work phases are clearly delineated throughout the drawings, with construction details including concrete truck washout areas and underground electrical conduit and cable specifications.
