About this file
This document is a technical standards and specifications guide for the City of Midland, Texas, detailing utility infrastructure installation requirements for the Utility Extension Program 07. The guide establishes comprehensive design standards for water mains, wastewater mains, storm drains, and dry utility systems within various street classifications including arterial streets, collector streets, and local streets. The specifications cover utility main spacing, depth requirements, material standards, pipe sizing, and installation procedures for different right-of-way configurations. Key requirements include minimum cover depths for water mains (3.5 feet), wastewater mains (6.5 feet), storm drains (3.5 to 4.0 feet), and petroleum/natural gas lines (7.0 feet), with specific horizontal and vertical separation distances mandated between parallel utilities. The document provides detailed technical drawings and cross-sections illustrating proper installation methods, including trenching and bedding procedures, manhole construction and adjustment specifications, and fire hydrant placement protocols.
The specifications require all materials and construction methods to conform to City of Midland standards and must be approved in writing by the City Engineer prior to deviation from the stated details. Special provisions address water and wastewater main crossings, requiring minimum 9.0-foot horizontal separation distances and specific vertical clearances depending on pipe type and pressure rating. Service lateral requirements for both water and wastewater systems are detailed with specific component specifications, including approved meter assemblies, corporation stops, curb stops, and service line materials. The document mandates pressure-rated or heavy-wall gravity pipe for wastewater mains in parallel with water mains, cement-stabilized sand encasement for certain crossings, and specialized pipe casing requirements with minimum 18-foot lengths at crossing points. All pipe penetrations, fittings, and connections must be constructed with specified materials including ductile iron, PVC, polyethylene tubing, and approved equivalents, with tracer wire requirements for locating subsurface utilities.
