Water main proximity to building

[Jonny]

Hi everyone,

 

I'm in the process of purchasing a barn with permission for conversion + extension (not class Q). The stone/cob barn is thought to be 150+ years old (to be checked) and is in quite a state, but ultimately needs to be saved and repaired as part of the permission. 

 

The challenge comes with the water main; initial south west water drawings indicate the 200mm main is around 4m from the barn wall. However, on further review and scanning, it appears the main is around 2m from the wall. This impacts the 3.5m build limit imposed by South West Water. 

 

I understand that this would not have been permitted for a new build this close to the water main, but where do we stand with converting a property in this proximity? 

 

It's probably a question for SWW/planners, but just reaching out to see if anyone had any prior experience/knowledge?

Which came first, the building or the main... 😉

 

You are spot on that you need to talk to the water company. There are special rules relating to existing situations and special situations. Let's say there was a water main 1m from a town centre row of buildings, but there was supposed to be a 6m easement (3m either side of the main). It is acceptable in these circumstances for a 1m from the buildings and 5m at the other side in these special circumstances. Generally it's just the amount of space that contractors would require to safely work on it. And as you've found out, the centreline isn't always that accurately surveyed!

 

Just speak to the water company; they will be able to advise you on what you need to be aware of.
