Utilities

utility installations by J316 Excavation
San Antonio Water Systems certified contractor J316 Excavation

Installing utilities is a key part of site work and happens before buildings and paving are completed. It’s a coordinated, regulated process handled by licensed professionals to ensure safety, reliability, and compliance.

​

J316 Excavation is a certified contractor with SAWS, CPS Energy, City of San Antonio Public Works and several other municipalities.  There are very strict requirements for experience, insurance and quality of work , bonding, and background checks to be a licensed contractor.

Planning and Coordination

Before any digging:

  • Review engineering plans and utility maps

  • Coordinate with utility providers (water, power, gas, telecom)

  • Identify existing underground lines (locate/mark services)

  • Schedule work so utilities don’t conflict with each other

This step prevents damage and service interruptions.

Surveying and Layout

The exact paths and elevations are marked:

  • Trench locations

  • Connection points

  • Required slopes (especially for sewer lines)

Accuracy is critical for proper flow and access.

Utility Line Installation

  • Different utilities are installed in a planned order:

  • Water lines: Supply potable water

  • Sanitary sewer: Carry wastewater away (gravity-based)

  • Storm drainage: Manage runoff

  • Gas lines: Installed and sealed by licensed crews

  • Electrical & communications: Placed in conduits

  • Each system has spacing and separation requirements.

Testing and Inspection

Before backfilling:

  • Pressure testing (water and gas)

  • Leak detection

  • Flow and slope verification

  • Inspections by authorities and utility companies

Nothing is covered until it passes inspection.

Final Connections and Activation

After construction progresses:

  • Utilities are tied into buildings

  • Systems are activated by providers

  • Final inspections confirm readiness

Permits and Approvals

Utility installation requires authorization:

  • Excavation and right-of-way permits

  • Utility company approvals

  • Health and safety compliance checks

  • Inspections scheduled in advance

Trenching and Excavation

Soil is carefully removed to create space for utilities:

  • Trenches are dug to designed depth and width

  • Temporary supports may be used for safety

  • Excavated material is stockpiled or removed

Work follows strict safety standards.

Connections and Appurtenances

Supporting components are added:

  • Valves, meters, and cleanouts

  • Manholes and access boxes

  • Transformers or service pedestals (where applicable)

These allow operation, maintenance, and future access.

Backfilling and Compaction

Once approved:

  • Trenches are filled in layers

  • Soil is compacted to prevent settlement

  • Surface is restored temporarily or permanently
