Attachment J11 CC Community Sewer As-built (1975).pdf

This is an as-built engineering drawing from 1975 showing the sanitation facilities construction details for the Crow Creek Community water and sewer system in South Dakota. The drawing includes technical specifications for existing sewer mains, manholes, gate valve boxes, and drain fields, with a clear legend identifying these components. The drawing shows detailed pipe layouts, slopes, and connections, with specific measurements and elevations noted throughout the plan. This document appears to be part of the technical documentation supporting the current solicitation for renovating the existing community sewer system on the Crow Creek Reservation.

The drawing was originally created by the U.S. Department of Health, Education & Welfare Public Health Service Indian Health Service, and includes a north arrow and scale reference. The level of detail provided in this as-built drawing would be essential for contractors bidding on the current renovation project to understand the existing infrastructure that requires updating after nearly 50 years of service.
