Drainage problems can affect more than one household, especially when several properties use the same pipework. A blockage, leak, or damaged section may cause slow drainage or unpleasant smells in different homes. A CCTV survey of shared drains helps homeowners understand the condition of shared pipework and locate hidden faults without unnecessary digging.
Did you know that a single damaged section of a shared drain can affect several connected properties? Identifying the exact problem early can help prevent further damage and make repairs easier to manage.
What Are Shared Drains and How Do They Work?
Shared drains are underground pipes that carry wastewater from two or more properties. For example, neighbouring houses may connect to the same drain, which carries wastewater towards a public sewer.
These pipes may run beneath gardens, driveways, private roads, or shared outdoor spaces. Their layout depends on how the properties were originally built and connected.
A shared drain inspection helps homeowners understand the condition of this connected pipework. If damage is found, suitable solutions, such as drain pipe repair, can be considered before the problem becomes more serious.
Understanding these connections is important because a fault in one section can affect several households.
What Problems Can Develop in Shared Drains?
Shared drainage systems can develop different problems due to regular use, ageing materials, ground movement, and external damage.
Some common issues include:
- Blockages: Grease, wet wipes, sanitary products, and other debris can build up inside pipes and restrict wastewater flow.
- Cracks: Ageing pipes or ground movement can cause cracks, allowing wastewater to escape.
- Root intrusion: Tree roots can enter through small gaps in pipe joints and grow inside the drainage system.
- Leaks: Damaged pipes and loose connections may allow wastewater to escape into the surrounding soil.
- Displaced joints: Pipe sections can move out of position, creating gaps where debris collects.
- Collapsed sections: Severe structural damage can cause part of a pipe to collapse and stop wastewater from flowing properly.
These issues can affect one property or several connected homes. A CCTV drain inspection can help identify the exact location and condition of the damage, making it easier to plan suitable repairs.
How Can a CCTV Drain Survey Inspect Shared Pipework?
A CCTV drain survey uses a specialist waterproof camera to examine the inside of underground pipes. The camera is attached to a flexible cable or crawler system and carefully moved through the drainage network.
The process allows drainage professionals to inspect areas that are difficult to reach from the surface.
Here is what happens during the inspection:
- Accessing the drain: The surveyor uses an existing access point, such as a manhole or inspection chamber.
- Moving the camera: A small camera is guided through the pipework to examine its internal condition.
- Checking for damage: Live footage helps identify blockages, cracks, leaks, root intrusion, and displaced joints.
- Locating defects: Specialist equipment helps establish the position of visible problems along the pipe.
- Recording the findings: The surveyor captures footage and prepares a report explaining the condition of the inspected drainage system.
This process helps homeowners understand what is happening underground without immediately digging up gardens, paths, or driveways.

Can a Survey Show Whether the Problem Is Shared or Property-Specific?
Yes. A CCTV survey can help identify whether a drainage problem affects one property or a shared section of the pipework.
If only one household experiences slow drainage, the blockage may be within its private drain. However, if several households face similar issues, the fault may be further along the shared drainage network.
This is especially useful when inspecting shared drains between houses, as the damaged section may be away from the affected property. Professionals can examine pipe connections and follow the drainage route to locate the fault.
Access to the relevant pipework is important, and multiple entry points may be needed to inspect the complete system.
How Does a CCTV Survey Help Locate the Exact Fault?
Finding a drainage problem is only the first step. Homeowners also need to understand where it is happening and how serious it is.
A CCTV survey provides recorded footage that helps drainage professionals identify defects and assess their condition.
The inspection can help with the following:
- Finding blockages: Shows where debris has collected and restricted water flow.
- Checking pipe joints: Reveals gaps, movement, or separation between connected pipe sections.
- Identifying root entry: Shows where tree roots have entered the pipe and affected its internal space.
- Assessing structural damage: Helps identify whether a pipe has minor cracks or more serious damage.
- Planning repairs: Provides useful information for selecting suitable repair methods and avoiding unnecessary excavation.
A CCTV drain inspection can also help investigate recurring shared sewer problems by showing whether the same damaged section is affecting multiple properties.

Who Is Responsible for Repairs to Shared Drains?
Responsibility for shared drain repairs can be confusing, particularly when several households use the same pipework.
In England and Wales, many shared private sewers and lateral drains were transferred to water and sewerage companies in 2011. However, this does not mean every shared drain automatically belongs to the water company.
Responsibility depends on several factors:
Factor | What homeowners should check |
Pipe location | Whether the drain is within private property or outside the relevant boundary. |
Adoption status | Whether the water company has formally adopted the pipework. |
Property arrangements | Whether private agreements or shared maintenance arrangements apply. |
Local regulations | Which drainage authority is responsible for the relevant section. |
A CCTV survey can provide useful evidence about the location and condition of a damaged section. Homeowners can use this information when contacting neighbours, property management companies, or the local water company.
It is always worth confirming responsibility before arranging or paying for repair work.
What Should Homeowners Do After a CCTV Drain Survey?
Once the inspection is complete, homeowners should review the findings and decide what action is needed.
Follow these steps to manage the next stage:
- Review the survey report: Check the recorded defects, their locations, and the overall condition of the inspected pipes.
- Understand the problem: Ask the drainage specialist to explain the damage and whether it affects other properties.
- Confirm repair responsibility: Contact the relevant water company or check property agreements before arranging work.
- Speak with neighbours: If the damaged section is shared, discuss the findings and agree on the next steps with the affected households.
- Arrange suitable repairs: Address identified problems promptly to reduce the risk of further damage and recurring drainage issues.
Keeping a copy of the survey report and recorded footage can also help when discussing repairs with the responsible parties.
