Woops missed the comments from the 31st, soz.
I'm just wondering how the last job an engineer was closed, the reason for this is thta any fault will have a "clear code" which states what and where the fault was. Theres a huge list, there was a briefing sent out with the broadband clear codes, the REIN ones were missed off so many arn't aware of them. With the right code the the job details as I understand gets highlighted to the REIN group who will raise a new job and get it pinned to the local REIN guys. The last couple of ones I had I go due to the engineers calling our control so they could intervene and pin me the job manualy as they wern't aware of the clear codes. Otherwise it comes down to what the ISP wants to do based on the job notes. I'm thinking the're not familiar with REIN as it's an unusual fault.
Your locating the noise apparently comming from the pumping station seems quite likely to be the source, What you've done to locate it and tie it up with your drops of service is spot on. unfortunately if thats the case then there's nothing bt can do directly. I'm not sure what exactly happens here but I assume the REIN SFI desk would ger in touch with offcom as they have the power to act against any unauthorised or interfering forms of radio emmission. If I had this fault then it's a case of my identifing as best I can that the source is causing an issue with your dsl, then the Ofcom guy has kit which can directonaly locate noise soruces across a wide range of frequencys and they have the power to interceed. I think this covered only by ofcom as otherwise we could have all sorts of bodies running round demanding all sorts of kit is shut down.
REIN can come from a single source as a point, or broadcast it back down the mains so all the local wiring is acting like an antennea. on the flip side all or part of the telephony can act as a reciving antennea from the cableing up to and including the router. and some times it's a case of one particular set up by fluke being in tune with the noise so one person in a locality suffers where as the others nearby much less so.
The only other things would be a change in e-side cable (never had a REIN cured by this) chnage in d-side (same result here) and an rf3 filter fitted, very occasionaly helps, (hence I have a test nte5 where I've built in an rf3 via a 8pole/double throw switch as a quick way of checking).
I would say keep herranging your isp to raise a REIN issue so those channels can be followed, otherwise I know you can contact ofcom your self with radio interference issues although I'm not sure how they will react in the case of a broadband fault and may refer you back to your ISP. There was somehting that came up localy, nothing to do with dsl but a chap was sure that his key fob wouldn't lock the vehicles within 50m of his house after a bt aerial cable was recently installed nearby, he got ofcom to send one of thier specialists over who located the source as the trickle heater in his motor home. Apparently he got a £314 bill for the call out from ofcom
