What Is Drain Mapping and Why Do I Need it?

If drain mapping is something you’ve heard of but you’re unsure exactly what it is, then don’t worry, we’re here to help. And if you’ve never heard of it at all, then you’ve definitely come to the right place.

This month at 1st Call Drain Clearance & Technical Services, we’ll be taking you through exactly what drain mapping is – including how it’s carried out – and why you might need it. So whether you’re a homeowner or a business owner with your own premises, read on to find out more.


What is drain mapping?

Drain mapping is exactly what it sounds like – a comprehensive map for your drains. 

It’s essentially a CCTV survey carried out within your drainage infrastructure, providing an accurate plan of where your drainage and sewage systems lie. This includes the location of manholes, gullies and more to aid in the creation of detailed schematics.


How is drain mapping done?

At 1st Call Drain Clearance & Technical Services, we use the latest, most innovative equipment to help perform a professional drain mapping service.

Our CCTV drain survey equipment is used in your pipework. This equipment is then worked through the system to accurately gauge where your drainage pipes run. Plus, if we encounter a blockage, we can use drain jetting to clear the way and continue with creating a clear picture of your system.


What can you learn from drain mapping?

There is so much to be learned from drain mapping, but most important is the full, clear picture you get of where your drainage system is. This will include details such as internal and external drain connections, the direction in which the water flows and even where chambers and manhole covers can be found. Our drain surveys will also let you better understand the functions of your drainage network, putting you in a more informed position going forward.

The boundaries of your drainage can also be figured out from drain mapping, something that’s important for a number of reasons, not least because it establishes what you’re responsible for on your property.

Now you know what you can find out, what can you do with this knowledge and why would you need it? Let’s look at that next.


Why do you need drain mapping?

The most common reason for drain mapping is for building work. Before you start any construction work or building work on your property, you’ll want to know where the drainage system is. This will help avoid unnecessary damage to your drains and can help you, your architect or your builder to decide what action should be taken where drainage networks are involved. Since drain mapping gives you the accurate location and depth of your drains, this can be used to inform your plans before any excavation begins.

Another reason why drain mapping is sometimes required is to manage flood risks and for pollution prevention – accurate mapping of your drains allows for better planning in these areas.
