CCTV Drainage Surveys Revealing Underground Problems
CCTV drain surveys include professional camera inspection of drains, sewers, and pipework: identifying blockages, damage, and defects.
Overview
Underground drainage problems are invisible until they cause flooding, backups, or pollution.
WCI Water & Wastewater Engineers provides professional CCTV drainage surveys tailored to your needs - from rapid connectivity surveys establishing drainage layouts through to comprehensive condition assessments with detailed defect reporting and video evidence.
What Is a CCTV Drainage Survey?
A CCTV drainage survey is a process where a waterproof camera is fed through a pipe on a rod or crawler unit, recording a continuous video as it travels further down. This is done so the surveyor can see what exactly the issue is inside the pipe without having to dig it up. Normally, access points like manholes, rodding eyes, and inspection chambers are the main entry points for a CCTV drain survey.
During the survey, the engineer will be able to spot any issues that could be affecting your pipes, including common issues such as:
- Cracks
- Root ingress
- Displaced or open joints
- Collapses
- Blockages
- Gradient issues
- Misconnections
The two survey types we conduct are Connectivity & Condition and Connectivity:
- A Connectivity Survey establishes the layout of your drains, including connections and flow routes.
- A Condition & Connectivity Survey is a complete assessment of your drain’s condition with detailed defect reporting.
Identify Problems Before They Escalate
CCTV drainage surveys use specialist camera equipment to inspect pipes and sewers, revealing condition, identifying defects and locate problems providing the information needed for targeted repairs rather than guesswork excavation.
Targeted Repairs
CCTV surveys locate problems precisely, enabling targeted repairs rather than expensive exploratory excavation trying to find issues.
Knowing exactly where problems exist saves time – Utilising our specialist knowledge in how to fix the problem saves money.
Persistent Blockage Investigation
Recurring blockages indicate underlying problems such as root intrusion, displaced joints or collapsed pipes.
CCTV reveals why blockages keep occurring, allowing us to design permanent solutions.
Pre-Construction Surveys
Before building extensions or developments, CCTV confirms existing drains are sound.
Discovering problems during construction causes expensive delays and disputes.
Adoption Surveys
Water companies require CCTV surveys before adopting sewers under Section 104 agreements.
Our surveys meet adoption authority requirements and identify defects preventing adoption.
Small cracks and defects worsen over time, eventually causing collapses and major failures. CCTV surveys identify problems early when repairs are simpler and potentially cheaper.
The WCI Difference
Our Project Engineers have surveyed & installed thousands of drainage systems - they can recognise defects that laymen may miss, understand what they mean for system performance and provide practical repair advice based on their end-to-end experience.
Tailored Survey Approach
We provide the right survey for your specific needs - rapid connectivity surveys when you need layout information quickly, or comprehensive condition surveys when detailed defect analysis is required. You don't pay for more than you need.
Complete Investigation
If CCTV reveals problems requiring further investigation (excavation, testing, repairs), WCI Group can deliver repairs after the survey, providing continuity from investigation through to resolution.
Honest Assessment
We report what we find honestly, if drains are sound, we say so. If defects exist, we explain severity, implications and realistic repair costs. Our reputation depends on accuracy, not exaggerating problems or skimming over the finer details.
CCTV Survey Process
Initial Consultation
We understand your requirements and the type of survey required, which will either be a Connectivity Survey or a Condition & Connectivity Survey.
Desktop Review
We prepare for an efficient survey by reviewing existing drainage plans, previous survey records, and site access restrictions.
Site Survey
The professional CCTV inspection typically takes 2-4 hours depending on the survey type, system extent, and its complexity.
Report Preparation
After the survey, we create a full document of what we found and what next steps are needed. Reports are typically delivered within 5 working days of the survey.
Report Discussion
We explain the technical defects we found in plain language, providing repair quotations if requested, and coordinating repairs if you choose WCI to carry out the works.
When Would You Need a CCTV Survey?
Home Buyers & Sellers
Anyone purchasing property will need confidence that drains are sound. Vendors will also want to address drainage issues before marketing, or demonstrate drain condition to potential buyers to prevent survey issues from derailing sales.
Homeowners with Drainage Problems
Property owners experiencing recurring blockages, slow drainage, or suspected problems need CCTV identifying root causes and enabling targeted repairs.
Self-Builders & Renovators
Understanding existing drainage layout before design work, or baseline surveys before construction, helps to protect against damage claims. Pre-construction surveys are especially important for listed or period properties where constraints make it harder to fix mistakes discovered later on.
Commercial Property Owners
Businesses, hotels, restaurants, industrial facilities requiring drainage condition surveys for maintenance planning, insurance claims, or compliance.
Water Companies & Contractors
Adoption surveys for Section 104 agreements or condition surveys informing repair programmes and capital planning.
