These are engineering design drawings for a water main extension project in Grayhorse, Oklahoma, prepared by Caylen Willingham, a professional engineer. The seven-page technical document details a sanitation facilities construction project for the Indian Health Service (IHS) under Public Law 86-121, Project No. OK-23-F80. The drawings provide comprehensive technical specifications for installing water infrastructure, including detailed plans for:

• Water main extension along Little Star Drive
• Installation of gate valves, air release valves, and water meters
• Roadway crossings and trench details
• Thrust block settings and minimum dimension requirements
• Casing insulators and typical installation techniques

The project involves bore work under roadways, installing HDPE casing, connecting to existing water mains, and setting up flush hydrants. The design includes precise station markers (STA) indicating specific installation locations and technical requirements for each infrastructure component, with engineering specifications ensuring proper construction methodology and infrastructure integration.
