Sewer Adoption Surveys
what we do
Sewer adoption surveys are essential for confirming that new drainage systems meet the necessary technical and quality standards required for handover to the local water or highways authority. At Exjet, we provide accurate and fully compliant adoption surveys for developers, consultants, and contractors across the South West. Our work supports Section 104 and Section 102 sewer adoptions under the Water Industry Act 1991, as well as Section 38 and Section 278 agreements related to new roads and their drainage.
What Sewer Adoption Surveys Cover
We provide detailed surveys for both private and adoptable drainage networks, covering foul, surface water, and combined systems. Each inspection is performed in accordance with the Manual of Sewer Condition Classification (MSCC5) and specific water authority or highway requirements. Our teams capture high-quality CCTV footage, conduct condition assessments, and record data for every pipe, chamber, and manhole to verify construction quality and compliance with approved drawings.
S104, S102, S38 & S278 Surveys
Exjet’s experience extends across all major adoption types.
Section 104 & Section 102 Surveys
These surveys verify that newly built or modified sewers comply with the adoption standards set by the local water authority. Using high-resolution CCTV cameras and calibrated measurement tools, we evaluate the condition and structural integrity of the system, providing the documentation needed for authority approval.
Section 38 & Section 278 Surveys
For highway drainage, we conduct surveys required under Section 38 and Section 278 agreements of the Highways Act 1980. These inspections confirm that highway gullies, pipelines, and chambers have been constructed according to approved designs and are prepared for handover to the relevant authority.
Our Process & Deliverables
Every project starts with a consultation to confirm scope and authority requirements. Our engineers then carry out CCTV drainage surveys supported by jetting and cleaning to ensure clear visibility. Data is logged according to MSCC5 standards, with all observations classified and coded for accuracy. We produce as-built drawings, STC25 manhole record cards, and digital reports suitable for direct submission to Water Authority, local councils, or highways authorities. Where defects are identified, we provide recommendations for remediation and can complete any necessary remedial works through our in-house repair teams.
As-Built
We provide comprehensive as-built documentation services, delivering high-quality drawings in AutoCAD (ACAD) format to support accurate project records and future maintenance requirements. Our team also produces detailed manhole record cards in full compliance with STC25 standards, ensuring consistency, accuracy, and regulatory approval across all submissions. These outputs are prepared using industry-best practices to support design validation, asset integration, and client handover.
Standards & Compliance
All adoption surveys are conducted in accordance with the Water Industry Act 1991, the Design and Construction Guidance, and MSCC5. Our engineers are trained in confined space entry, CCTV inspection, and New Roads and Street Works (NRSWA) supervision, ensuring every aspect of the survey complies with relevant health, safety, and technical standards. We also implement strict quality management procedures to ensure consistency, traceability, and accurate reporting on every project.
Who We Work With
Our clients include housing developers, civil engineers, local authorities, and groundworks contractors. Whether required at the start of a development, during interim inspections, or for final handover, we offer flexible involvement to suit each project’s needs. We can also act as a consultant, reviewing drainage design or advising on compliance requirements before construction begins.
