Located Through Site Plans and Utility Maps
Utility connection points—such as water, sewer, electricity, gas, and telecommunications—are identified in official site plans and municipal utility maps. These documents show the exact location of existing service lines and access points.
- Utility maps are maintained by local utility providers or public works departments
- Site plans mark connection points at property lines or designated easement areas
- Locations vary depending on infrastructure layout and adjacent development
Determined by On-Site Inspection and Utility Locating Services
Professional utility locators or engineers use equipment to detect underground lines and mark connection points on-site. This step is essential before any excavation or construction begins.
- Utility locating services (e.g., 811 in the U.S.) prevent damage to buried infrastructure
- Visual markers such as utility boxes, meters, or manholes indicate surface access
- Ground-penetrating radar and electromagnetic tools are used for precise mapping
Required for Permitting, Engineering, and Construction
Accurate identification of utility connection points is critical for development design, permitting, and budgeting. Misidentification can lead to costly delays, redesigns, or safety hazards.
- Determines routing of service lines and equipment placement
- Informs trenching, grading, and foundation plans
- Necessary for compliance with building codes and utility provider requirements
