Neighbour has sub-standard drains pipe

[odyssey06]

A relation of mine has experienced blocked drains intermittently, along with some of her neighbours. Eventually they got a drains company out and they put a camera down.

One of the neighbours closest to the main drain has a section of pipe that was only 4 inches diamater (cms?) whereas it should be 8 inches and this is causing a bottleneck.

The neighbour is trying to brazen it out blaming contractors he hired for what and generally doesn't seem to want to do anything about it. The neighbour is a LL so not personally directly impacted.

Anyone know who is the best authority for my relation to raise this with?
Planning enforcement? Or is it a civil matter?

A check with the local authority Drainage Services will confirm, but there's a good chance that this is a shared private drain. That being the case, there's a collective responsibility among the owners of property it serves to maintain it and resolve issues.

Drainage Services will likely have similar issues before and be able to advise on options, but it may take civil action, of the threat thereof.

Did your neightbour's work require/ have planning permission?

Thanks for that. We think it relates to work done where an extra house was slotted in at end of terrace in what was their large garden, so there would be planning permission on that aspect of it.

Ah, that's perfect so as it increases your options. Check out the planning online, it likely has details, and perhaps even conditions attached as to the treatment of waste. Planning Enforcement may be able to help.

Is there any chance the bottleneck was always there what I am asking is there a possibly the neighbour nearest to the main drain originally put in a 4 inch pipe houses got added later and they put in a 8 inch pipe joining it up to the existing 4 inch pipe,

Seen it happen in the past .for someone to take up an 8 inch existing pipe and replace it with a new 4 inch pipe would cost more when you take the fitting and extra work into account, are you sure contractors replaced an existing 8 inch pipe with an new 4 inch pipe

Is the Neighbour talking about the original contractor who put down a 4 inch pipe at the beginning which was good enough to service there house at that time,

PS
only seen post no 3 now Did they actually remove a 8 inch pipe and replace it with a 4 inch pipe,

The impression my relative got from the drainage company was that everyone else was at 8 apart from this one stretch, which possibly used a 4 during the relatively recent works to connect the new house in the last 5 years.

But I will mention this as a possibility i.e. is everyone else on a 4 and there's a single 'new' stretch of 8 which then clogs up at the next 4.

Sorry odyssey06
Is the 4 inch pipe a new pipe replacing a 8 inch pipe on the system,

or is there an old stretch of 4 inch pipe that needs to be upgraded to the same size as the rest of the system because there is now a higher volume going trough the system ,

No worries, sorry I wasn't clear either -> It looks like a new 4 inch pipe in an (older) 8 inch network.
