What is a CCTV drainage survey?

A CCTV drainage survey is a detailed visual inspection of an underground drainage system using a remotely operated camera deployed through existing access points – manholes, inspection chambers and gully pots. The camera travels through the pipe, recording a continuous video record of the internal condition of every pipe run inspected – identifying defects, blockages, root intrusion, structural failure, mis-connections and any feature that affects the drainage system’s performance or condition.

Accurate CCTV drainage data reduces design risk, prevents costly groundworks surprises, supports planning condition discharge, and ensures drainage systems meet adoption standards before the adoption process begins. A CCTV drainage survey from Site Surveying Services forms the reliable foundation for:

Drainage adoption

Inspection and condition records to WRC Sewerage Rehabilitation Manual (SRM) standards and to the requirements of the adopting authority - local authority highway drainage or water company - before Section 38, Section 278 or Section 104 adoption processes begin.

Planning condition discharge

Documented CCTV drainage inspection records that satisfy LPA drainage conditions and LLFA requirements on residential, commercial and infrastructure development.

Pre-purchase and due diligence

Condition records of existing drainage infrastructure before property or land acquisition - identifying defects, capacity issues and maintenance liabilities before contracts exchange.

Drainage design and problem investigation

Condition and capacity data for drainage designers investigating existing systems - blockages, structural defects, mis-connections, surcharging and drainage performance issues on existing sites.

Pre-construction and as-built records

CCTV inspection of drainage before and after construction - confirming existing condition before works begin and producing the as-built drainage record at completion.

Our CCTV & Drainage Survey Services

Our CCTV & Drainage Survey Services

Underground drainage infrastructure cannot be designed around, adopted or maintained without knowing its condition. Estimating what is below ground – based on old records, assumed pipe routes or construction drawings that do not reflect what was built – produces drainage designs, adoption submissions and maintenance programmes that fail when the ground is opened and reality does not match the assumption.


Site Surveying Services delivers CCTV drainage surveys across Lancashire, the North West and nationally – for drainage engineers, planning consultants, developers, local authorities, highway authorities and construction contractors who need verified condition data on underground drainage systems. Our team is directly employed. Every survey is planned, delivered and processed in-house – the same organisation that quotes your job is the team that completes it. All inspections are carried out using professional-grade CCTV equipment, coded to recognised industry standards, and delivered in the format the adopting authority and drainage engineer require.


The people who commission CCTV drainage surveys from us are the people whose adoption submission, drainage design and planning condition discharge depends on the data being right. We understand what that means.

Pipe Condition Recording

Full internal CCTV inspection of each pipe run - continuous video record of internal condition, structural defects, root intrusion, joint displacement, debris, blockages and all visible features.

Defect Coding

All defects identified and coded to WRC Sewerage Rehabilitation Manual (SRM) standard or the adopting authority's specified coding system. Defect schedule produced for each pipe run inspected.

Drainage Layout Plan

Georeferenced drainage layout drawing showing all inspected pipe runs, manholes, inspection chambers, gully connections, invert levels, pipe diameters, materials and flow directions. Produced in AutoCAD DWG and PDF format.

Manhole Inspection

Visual inspection of all accessible manhole and inspection chamber structures - cover condition, frame, step irons, benching, channel and any structural defects recorded and reported.

Invert and Cover Level Survey

Invert and cover levels of all manholes and inspection chambers surveyed using GPS and/or total station instrumentation and recorded on the drainage layout drawing for adoption and drainage design purposes.

CCTV Video Record

Full video record of every pipe run inspected, delivered as MP4 files referenced to the drainage layout plan. The complete, timestamped visual record of the drainage system's condition at the date of survey.

As-Built Drainage Record

Where CCTV survey is commissioned at practical completion of new drainage, the as-built drainage record confirms the completed pipe runs, invert levels, pipe diameters and materials as constructed - the document required for adoption.

our Topographical survey case studies

BAE Systems — Barrow-in-Furness

As part of a major facility expansion at the BAE Systems site in Barrow-in-Furness, Site Surveying Services delivered a comprehensive topographic and PAS 128 utility mapping survey to support the design of new on-site parking and associated infrastructure. Working within a live operational industrial environment, our team captured existing ground levels, surface features, boundaries and drainage in a single coordinated, georeferenced dataset. Phased delivery, real-time quality assurance and cross-discipline coordination between our topographic and utility mapping teams ensured zero disruption to site operations and no requirement for return visits. The completed dataset now underpins critical design decisions for the facility expansion.

Urban Regeneration Surveys — Darwen, Colne and Accrington

Topographic surveys across multiple East Lancashire urban regeneration sites — OS-controlled survey data capturing ground levels, boundaries, drainage, services and existing features for housing-led regeneration schemes. Delivered in the format required by the planning authority and design team, supporting planning submissions across all three schemes.

How CCTV & Drainage Surveys Integrate With Other Services

How CCTV & Drainage Surveys Integrate With Other Services

CCTV drainage survey delivers its maximum value as part of a coordinated package. The most effective combinations: CCTV and PAS 128 utility mapping are the most powerful pre-construction combination. PAS 128 locates and verifies all underground services using GPR and EML. CCTV provides the internal condition record. Together — a complete picture of underground infrastructure from one instruction. CCTV and topographic surveys use site levels, drainage layout, invert levels and surface drainage features in a single coordinated dataset. Everything the drainage engineer and architect need from one site visit. CCTV and impermeable area survey are where both drainage condition and impermeable area measurement are required for a planning application or condition discharge, one visit is always more efficient than two. CCTV and setting-out is  where our setting-out engineers are on a drainage construction programme, we coordinate CCTV as-built inspection at practical completion alongside the setting-out service — producing the adoption record as part of the overall programme.

Frequently Asked Questions

Frequently Asked Questions

What is a CCTV drainage survey?

A CCTV drainage survey is a detailed visual inspection of underground drainage pipes using a remotely operated camera deployed through existing access points. The camera travels through the pipe recording a continuous video of the internal condition — identifying structural defects, blockages, root intrusion, joint displacement, mis-connections and any feature affecting drainage performance. The output is a video record, a georeferenced drainage layout plan and a defect schedule coded to an industry-standard coding system.

CCTV drainage surveys are required at several distinct programme stages. Before drainage adoption — Section 38, Section 278 or Section 104 — to confirm the drainage is in adoptable condition. Before property purchase to establish the condition of existing drainage before contracts exchange. Before construction begins to record the pre-construction condition of existing drainage adjacent to the works. At practical completion to produce the as-built drainage record for adoption and planning condition purposes. For problem investigation where drainage is surcharging, flooding or failing.

PAS 128 utility mapping locates and verifies underground services — including drainage — from the surface using ground-penetrating radar and electromagnetic detection. It identifies where pipes are, what type they are and how deep. A CCTV drainage survey inspects the internal condition of drainage pipes using a camera deployed through access points. It tells you what condition the drainage is in. Both are needed on most construction and development sites – PAS 128 before any excavation, CCTV before adoption and at pre-purchase. We deliver both from a single coordinated instruction where both are required.

We code drainage defects to the WRC Sewerage Rehabilitation Manual (SRM) standard as default – the industry-standard coding system used by the majority of adopting authorities and drainage engineers in the UK. Where a specific adopting authority requires a different coding standard, confirm this at the time of instruction and we will code to the specified system.

Section 104 adoption of new drainage by the water company typically requires a CCTV inspection record of all adoptable drainage – confirming the drainage has been constructed in accordance with the approved design, is structurally sound, is clear of obstruction and meets the water company’s technical standards. The CCTV record, drainage layout drawing, manhole schedule and as-built information are all part of the adoption submission. We produce these in the format the relevant water company requires and advise on specific requirements at the time of instruction.

The drainage layout plan is delivered in AutoCAD DWG and PDF format. The defect schedule and manhole schedule in PDF and spreadsheet format. The CCTV video record as MP4 files referenced to the drainage plan. If your drainage engineer requires the data in a specific format for drainage design software, confirm this at the time of instruction.

Yes. CCTV drainage survey is typically carried out from manhole access points without requiring excavation. On live operational sites – occupied buildings, active construction programmes, operational highways – we plan the survey around the operational requirements of the site and coordinate access with the facilities manager or site manager before each visit. For highway drainage surveys, where manhole access requires lane management, we produce a traffic management plan for every highway drainage survey.

Yes. Our head office is in Clitheroe, Lancashire, with additional offices in Matlock, Newcastle and Bristol. We deliver CCTV drainage surveys across the North West, North East, Midlands, South West and nationally. All work is delivered by our directly employed team – not subcontractors.
