Getting Ready for Sewer Adoption: What Section 104 Surveys Involve
Section 104 surveys are a key part of adopting new drainage systems. They’re usually required before a water authority agrees to take over responsibility for a sewer network on a new development.
In growing areas across Essex, such as Rayleigh or Wickford, these surveys are an essential step for developers looking to finalise drainage infrastructure.
What Is a Section 104 Survey?
A Section 104 agreement refers to part of the Water Industry Act 1991. It allows a private developer to build sewers to an agreed standard, with the understanding that the water company will later adopt and maintain them.
Before adoption, a detailed survey is carried out to ensure the sewers meet strict technical standards.
What Does the Survey Involve?
The Section 104 survey usually includes:
- CCTV drainage inspections
- Air or water pressure testing
- Structural condition reports
- Verification that pipe gradients, joints and materials meet the specification
If faults are found, remedial work is required before the water company will sign off on adoption.
Why Are Section 104 Surveys Important?
Without a successful survey, the water authority won’t adopt the sewer, leaving future responsibility (and cost) with the developer or property owners. Early inspection helps avoid costly rework or disputes later on.
For new housing estates or commercial builds in areas like Clacton or Epping, a compliant 104 survey is vital to keep the handover process smooth.
Conclusion
Section 104 surveys ensure new drainage networks meet standards for adoption. They protect developers, homeowners and local infrastructure by verifying quality from the outset. If your site is approaching final stages, getting the right drainage survey in place is a must.
