Survey of Drainage System

When you manage a property, dealing with drainage problems can quickly become a massive headache.

From nasty overflows to blocked drains, what can look like a minor issue on the surface can end up pointing towards hidden drainage issues deep within the drain system.

Arranging expert CCTV drain surveys through reliable professionals is the best way to identify issues early and avoid unexpected costs.

Through 24Housing, you can get drain services via a trusted and reliable consultancy that we refer to from our vast network.

What is a Drainage Survey?

A basic CCTV drain survey is a non-invasive inspection of your drainage setup using an advanced type of CCTV camera.

During a CCTV inspection, qualified engineers evaluate the condition of the drains and see the current condition without digging up the ground, helping to detect issues inside the drainage pipes by streaming real-time video footage straight to a monitor.

An in-depth inspection will help you to understand the condition of the drainage, as a standard visual inspection can only tell you so much about what is underground.

A comprehensive CCTV drain inspection uses specialist cameras to map the layout, with the drain camera survey offering a professional inspection that uncovers blockages, cracks and collapses.

The partner company we work with delivers a thorough inspection of your property’s drainage system to identify defects before they cause structural damage.

It could be that you need a standard CCTV drainage survey to check key works or a complete drainage inspection across a larger site. Whatever the situation, our team can help you with arranging the assessment you need.

Purposes for a Commercial Drain Survey

For businesses, a breakdown in plumbing can halt operations entirely, and large commercial properties often rely on complex drainage networks that handle massive volumes of water.

A commercial survey serves several vital purposes, including helping to identify problems like frequent blockages or structural damage before they escalate into major problems.

Mapping the entire system allows engineers to help you plan maintenance effectively. By proactively scheduling preventative maintenance, you can safeguard your business against unexpected operational downtime and mitigate all potential issues.

From dealing with recurring problems and processing insurance claims to arranging future maintenance and checking for structural issues with your drainage, an accurate survey guarantees that all of your drainage needs are met.

It considers multiple criteria to deliver accurate results, highlighting potential problems and addressing possible drain issues.

Possible Clients

While most people assume that a full CCTV drain survey is only needed in the case of severe emergencies, they can actually help with other matters, such as a property purchase.

If you are buying a house, many mortgage lenders will request pre-purchase inspections before approving your loan. With a dedicated home-buyers’ drain survey, you can make sure that your new home doesn’t have serious problems with the drainage.

Between buying a property and managing rental properties, private owners and landlords need to refer to these checks to protect their investment.

Detailed inspections for drainage give banks confidence that the building is structurally sound. While surveyors look for structural flaws or poor insulation in the walls, for instance, checking the drains can be just as important.

Getting a clear picture before closing a deal is smart business in the eyes of home buyers and commercial investors. For residential properties, a basic check is fine, but for larger properties, a broader scope is necessary.

Verifying the structural integrity of pipes can even be a legal requirement when it comes to planning building work, and it can prevent common issues that develop gradually into significant issues.

Elements of CCTV Surveys for Drains

Specialists will deploy advanced CCTV technology in order to see exactly what is going on. A specially designed camera is attached to a flexible rod, feeding it through existing access points like manholes in the road outside the property.

The specialist equipment allows the consultants to capture high-definition CCTV footage in real time, as well as the option of specific additional camera equipment for different settings, such as waterproof CCTV cameras for fully submerged environments.

More often than not, the cameras are separated into two types: push cameras for smaller lines and robotic crawlers for main sewers.

Using different types of advanced drain surveillance tools, technicians can monitor live footage on a screen outside.

As a whole, the process usually takes somewhere around two hours to complete, but having the necessary equipment on-site guarantees that nothing important is missed.

Process for a Drainage Investigation

Carrying out a thorough drain survey follows a step-by-step method:

  • Access and Insertion: The first step involves locating entry manholes before engineers feed the camera line in, and the camera travels through the space and captures everything happening inside.
  • Live Assessment: Technicians check the condition in real-time to find the root cause of slow flows, helping identify blockages as soon as the camera inspection begins.
  • Lateral Checks: Engineers evaluate lateral drains and run a point analysis to confirm the exact location of any defects.
  • Data Logging: The camera footage registers invert levels and build-up, with technicians going on to record images onto a digital storage medium to display the overall condition, highlight the most common causes of failure, and record all issues found that are causing problems.

Drain Survey Report

Once the drain survey has been completed, a detailed report will be put together.

It isn’t just a basic summary, instead acting as a formal written report outlining every detail. Simply put, a standard CCTV drain survey report covers a full structural breakdown of your pipes.

Comprehensive reports such as these mix survey findings with a detailed analysis of any defects, along with estimated repair costs.

Not only that, but a drainage survey report offers an opportunity for easy future referencing for dealing with insurers or builders further down the line. The full report from the survey accompanies your planning submissions to fulfil administrative duties with minimal disruption to your schedule.

If ground conditions indicate that your development may require structural modifications, the records of the drainage survey will offer the best insurance for your planning project.

By knowing all these details upfront, you are ready if it turns out that you may need minor layout adjustments.

Drainage Survey Tools and Equipment

  • Tilt Cameras: A tilt drain survey camera rotates to inspect side connections closely.
  • Laser Profiler: Uses laser profiling to measure exact pipe size and detect internal warping.
  • EX-Rated Equipment: A specially rated camera safely navigates inflammable environments in high-risk commercial setups.
  • Pipe Profiling Tools: Used to identify pipe materials like clay pipes and log varying pipe diameters.
  • High-Resolution Units: An advanced CCTV camera captures clear, detailed images throughout the run.

Cost of a Drainage Survey

Common Questions

The total price will vary depending on the level of detail required and the building size. Older properties and buildings with complex layouts often require CCTV surveys that take a bit longer to complete on-site.

Common drain problems include slow drainage, blocked sinks or blocked baths. If you notice slow-draining sinks, persistent bad smells or a foul smell from plugholes, something is wrong underground. You might also spot damp patches on walls. Repeated blockages or recurring issues mean the root cause needs attention.

Underground pipes suffer from wear and tear and pipe deterioration over time, especially in older drainage systems. Structural movement from ground movement can crack pipes easily. Tree root ingress or tree root intrusion from mature trees is also a major threat. It often leads to collapsed drains, collapsed pipes or collapsed sections, as well as cracked pipes, displaced joints or misaligned joints.

Book a pre-purchase drain survey before exchanging contracts on a property. It checks a home’s drainage system for existing damage or hidden issues before you commit. Taking this step is always worth it to save you from inheriting costly repairs down the line.

While minor blockages are easy to clear, major drain blockages or blocked sewers need specialist care. Engineers use drain cleaning like high-pressure drain jetting or drain jet vacuumation. Following sewer inspections, specialists perform drain repairs, sewer repairs or sewer rehabilitations. They often use drain relining to seal cracks internally. The remedial work or repair work handles necessary repairs quickly to prevent further damage and reduce total work required.
