Yep, that's the one. They are in place to drive improvements at all STWs.What is the AMP? Asset Management Period 6 that is for keeping the infrastucture in good order?
Yes, it all gets a bit long winded:
The next three images show the historical samples. It is rather obvious the test site nearest the sewage works has been a consistent fail.

Why have they drawn the line on the graphs towards the top of the data. It seems to me that the lines should be lower down somelwhere in the middle of all the data points.
So somewhere closer to 3 mg/l
Unfortunately, the rules say that if Nitrate spikes above the limit, regardless of where it comes from, Agriculture automatically goes into NVZ regs.
2 points to make here.
A few years ago a group of farmers in the Cheshire area maybe near Manchester got their land out of NVZ by proving the pollution was being found at the sewage outfall points into rivers as the OP says.
2nd point is that being in an NVZ is (especially to owner farmers) quite an advantage as grants are available for various bits and bobs especially roofs for concrete yards.
No farmer should need to be told that the ability to spread when nutrients are most needed is a good thing.
Wrong on 2nd point, some areas in NVZ's can indeed get grants as you say, others not. In fact I don't think these grants you mention are anything to do with NVZ, a mate of mine had a grant to cover his handling area but is not in an NVZ. Th girl who does my NVZ work has looked into it and there are no such grants available here., she also did his grant application.2 points to make here.

And as the urine is the liquid fraction wouldnt more pass through the works?Well, my sewage cake has around 9 kg/tonne fresh weight of total N in it, so it must have come from somewhere - our bottoms pehaps? Urine contains urea...
Any idea what the limit is? I seemed to think it was 50???
What makes you think a sewage works is handling a lot of nitrates though? What sources have they got?
If phosphate vulnerable zones come in look out, it will be difficult for a lot of people to do much about those.
From an NVZ point of view it doesn't matter where the N is coming from. EU regs mean if N is over the 50ppm the catchment goes into NVZ rules regardless of the source.
Yes, but what niggles me is that I expect 99% of the time, if you read the report, agriculture gets the blame. In many cases that simply isn't the truth, it's pure bullshite
And to top it off, these water companies are making shed loads of money out of the job and, apart from the odd fine which is peanuts to them, get crate Blanche to throw crap in the rivers.
