When you might need Section 104 Contractor
This service is typically commissioned when early signs point to a wider issue, when work needs to be planned before construction starts, or when existing systems are no longer performing as expected.
It is also common on extension and redevelopment projects where practical constraints, permissions, or sequencing need to be considered before work begins. In decision-stage terms, this is often where teams move from broad options into method selection, sequencing, and budget alignment.
For residential owners and commercial teams alike, getting clear advice at this stage helps avoid repeat disruption, controls costs, and leads to a more reliable long-term result.
We install Section 104 adoptable foul and surface water sewers for developments that must be vested with the water authority. Packages include pipe runs, manholes, connections, testing and records structured for S104 technical approval and bond release milestones.
