CCTV Drains Survey: Keeping Your Drainage System in Check

The drainage system plays a crucial role in maintaining a clean and functional environment, both in residential and commercial areas. However, underground drain pipes are often overlooked until a problem arises, leading to inconvenience and costly repairs. This is where a CCTV drains survey becomes indispensable. In this article, we will explore the concept of CCTV drains surveys, their benefits, applications, and how to choose a professional company to perform them.


What is a CCTV drains survey?

A CCTV drains survey involves the use of advanced technology to inspect and assess the condition of underground drainage systems. It utilizes closed-circuit television (CCTV) cameras that are specially designed to navigate through the pipes and provide real-time video footage of the interior. This technique allows for a detailed analysis of the drainage system, identifying any potential issues or defects that may require attention.

Importance of CCTV drains survey

Maintaining a healthy drainage system is crucial to prevent problems such as blockages, leaks, and structural damage. A CCTV drains survey serves as a proactive measure to detect any potential issues before they escalate into major problems. By identifying and addressing these issues early on, property owners can save significant time, money, and inconvenience in the long run.

How does CCTV drains survey work?

Equipment and technology used

CCTV drains surveys employ state-of-the-art equipment to conduct thorough inspections. Specialized cameras, mounted on robotic crawlers or remotely operated vehicles (ROVs), are inserted into the drainage system. These cameras are equipped with high-resolution lenses and powerful LED lights, enabling them to capture clear and detailed footage of the pipes’ interior.

Process of conducting the survey

The CCTV drains survey process typically involves the following steps:

  1. Preparation: The survey and drain unblocking team gains access to the drainage system through an existing manhole or access point. They set up the necessary equipment, including the CCTV camera, lights, and monitoring devices.
  2. Inspection: The camera is carefully maneuvered through the pipes, capturing high-quality video footage in real-time. Trained technicians closely monitor the footage, examining the condition of the blocked drains in Bristol and looking for any signs of damage, blockages, or other abnormalities.
  3. Analysis and reporting: Once the survey is complete, the recorded footage is reviewed and analyzed. A comprehensive report is then generated, detailing the findings, recommendations for maintenance or repairs, and any necessary follow-up actions.

Benefits of CCTV drains survey

Early detection of issues

One of the key benefits of CCTV drains surveys is the ability to detect issues at an early stage. The high-definition video footage provides a clear view of the drainage system, allowing the drain engineers to identify potential problems such as cracks, fractures, or blockages. Early detection enables prompt action, preventing further damage and costly repairs.

Cost-effective maintenance

Regular CCTV drains surveys can help property owners save money in the long run. By identifying issues early on, targeted maintenance and repairs can be carried out, minimizing the need for extensive and expensive remedial work. The proactive approach of CCTV drains surveys helps avoid emergency callouts and reduces the risk of severe damage to the drainage system.

Minimizing disruption and inconvenience

Conventional methods of inspecting drainage systems often involve excavation and disruption to the property. CCTV drains surveys, on the other hand, offer a non-invasive solution. The use of advanced camera technology eliminates the need for extensive digging or dismantling, minimizing disruption to the surroundings and reducing inconvenience for property occupants.

Applications of CCTV drains survey

Residential properties

CCTV drains surveys are highly beneficial for residential properties. They enable homeowners to assess the condition of their drainage systems, ensuring they remain functional and efficient. Regular surveys can help detect issues such as blockages caused by tree root intrusion, structural damage, or deteriorating pipes. This allows homeowners to take proactive measures and avoid potential plumbing emergencies.

Commercial buildings

In commercial buildings, proper drainage is essential to maintain a hygienic and safe environment. CCTV drains surveys are particularly useful for large-scale properties such as office buildings, hotels, and shopping centers. Regular inspections can help property managers identify potential problems and plan maintenance activities, minimizing the risk of disruptions to daily operations.

Municipal infrastructure

CCTV drains surveys play a crucial role in maintaining municipal infrastructure. Local authorities can utilize these surveys to assess the condition of sewer lines, stormwater drains, and other vital components of the public drainage network. Regular inspections enable authorities to address any issues promptly, ensuring the safety and well-being of the community.

Choosing a professional CCTV drains survey company

Qualifications and certifications

When selecting a CCTV drains survey company, it is important to consider their qualifications and certifications. Look for a company that employs trained technicians who are knowledgeable about drainage systems and have received proper training in conducting surveys. Certifications such as NADC (National Association of Drainage Contractors) provide assurance of their expertise.

Experience and expertise

Experience is another crucial factor to consider. A reputable company with years of experience in the field will have encountered a wide range of drainage issues and developed effective solutions. They will be familiar with different types of drainage systems and possess the necessary expertise to accurately interpret survey results.

Client testimonials and reviews

Reading client testimonials and reviews can provide valuable insights into the quality of service provided by a CCTV drains survey company. Check for feedback from previous customers to gauge their satisfaction level and whether the company delivered reliable, accurate, and professional services.

Common issues identified through CCTV drains surveys

CCTV drains surveys can identify various issues that may be affecting the drainage system. Some common problems include:

Blockages and obstructions: CCTV surveys can pinpoint the location and nature of blockages within the pipes, enabling efficient and targeted clearance.

Cracks and fractures: The high-resolution footage obtained through CCTV surveys allows for the detection of cracks and fractures in the drainage pipes, which can lead to leaks and further damage if left unattended.

Tree root intrusion: Tree roots can infiltrate drainage pipes, causing blockages and structural damage. CCTV drains surveys can identify the presence and extent of tree root intrusion, facilitating appropriate remedial measures.

Maintenance and repair recommendations

Based on the findings of a CCTV drains survey, specific maintenance and repair recommendations can be provided. These may include:

Clearing blockages: If blockages are detected, drain clearing techniques such as high-pressure water jetting or mechanical rodding may be recommended to restore proper flow.

Relining damaged pipes: In cases where pipes are found to be cracked or fractured, relining techniques such as cured-in-place pipe (CIPP) lining can be employed to repair the damage without the need for extensive excavation.

Removing tree root intrusion: If tree root intrusion is identified, specialized equipment can be used to remove the roots and prevent further blockages and damage.


In conclusion, a CCTV drains survey is a valuable tool for maintaining and inspecting drainage systems. It provides a comprehensive assessment of the system’s condition, allowing for early detection of issues, cost-effective maintenance, and minimal disruption. By choosing a professional CCTV drains survey company and acting on their recommendations, property owners can ensure the longevity and efficiency of their drainage systems.
