What is a Drainage Survey?
A drainage survey is an inspection conducted by a professional surveyor to determine the condition and efficiency of a drainage system. The main aim of conducting a drainage survey is to identify any drainage problems, such as blockages or leaks, and determine the best solution to fix them.
This survey is essential for property owners as it ensures the effective functioning of the drainage system, preventing any potential flooding or water damage to the property.
Methods of Drainage Survey
There are different techniques used to carry out a drainage survey:
- CCTV Survey - This is the most commonly used method. It involves the use of a camera attached to a flexible pipe that is inserted into the drainage system to capture footage of the inside.
- Dye Testing - This is used to detect leaks within the drainage system. A coloured dye is injected into the system, and if there are any leaks, the dyed water will appear on the surface where the leak is located.
- Smoke Testing - This is used to identify any blockages within the system. Smoke is introduced into the system under pressure, and if there is a blockage, the smoke will escape through it and appear on the surface.
When is a Drainage Survey Needed?
A drainage survey is needed for various reasons:
- If you are purchasing a new property, a drainage survey should be conducted to identify any underlying issues that may need fixing before you move in.
- If you notice any problems with your drainage system, such as slow-draining sinks or toilets, unusual smells coming from the drains or recurrent blockages, then a survey should be carried out.
- If you have made any significant changes to your property, such as extensions or conversions, it is advisable to have a drainage survey carried out to ensure that the drainage system can cope with the increased demand.
The Benefits of a Drainage Survey
A drainage survey provides several benefits to property owners:
- Identifies underlying issues before they become costly problems.
- Assures efficient drainage, preventing any flooding or water damage to the property.
- Can save money in the long run by detecting issues early, preventing extensive damage.
- Increases the property's overall value by ensuring that the drainage system is in good working order.

- Has experience in conducting drainage surveys and can provide references.
- Is qualified and accredited by a relevant professional body.
