Thanks Pete. Its just that it has been so long now, and I have seen so much ill-looking tripe from the mains, that I am already certain that the problem is from there. A few years back, I had a sediment filter installed right after the stopcock, and it turned brown very quickly. It is simply poor infrastructural work by the local body.
The brown stuff in the filter is most likely rust if you're fed from a cast iron main.
I expect your problem *IS* somewhere *AFTER* the stopcock.
cheers, Pete.
Yes, but all the brown sediment etc that builds up in the attic tank does come from the mains, because you will see the particles every now and then when you pour yourself a glass. I have never seen this in another water supply, there should not be this issue. There should be nothing in there, unless warnings are issued, which is the norm in most areas.
I think you have 2 options:
A. Do something to _prove_ beyond doubt that the water from the _stopcock_ itself is tainted.
B. Just live with it.
cheers, Pete.
The water guidelines arent strict here, apparently coliforms can be present, as long as they dont exceed a limit. The sediment and dirt we have is basically a breeding ground for all that stuff. I will get a full bacteriological test done independently, but the water supplier already did a test back in June, and although they would not send me out the results, they told me the water was 'fine.'
I think I have found the problem... tuberculation of the iron piping. All the brownish black stuff that we get is sloughed off these tuberculation deposits, and it also causes biofilm, which is at its worst in the summertime. This is exactly what is happening here to us.
Clot, you around?
Hi None. Yes!
Any thoughts on my last six-ish posts? Particularly the long one on
7th of Nov, 15:26, to be precise, lol.
It would appear that the main issue is a cast iron main that needs lining. The black particles are most probably iron based tough it could be fro some lining that is detaching from the main. The slime aspect is probably a bacterial film that develops in the main and quite posssibly in your pipework as well.
For a "permanent" fix relining would seem to be the way to go. However, somehow you are going to have to persuade the water dept of the need! Hence why I asked about your neighbour's experience. Pressure of numbers would help! How about approaching the Environmental Health inspectors?
Re zoning/ valving might be of some help but the only solution I suspect is relining of the main.

Considering how difficult it is to get the water department to even flush the mains (I rang them three times last week, they still havent come to do it), I don't have a chance of convincing them to line a big long pipe. They are doing this in multiple areas though, 'rehabilitating' the mains as they put it. My area is too far out of their target areas though.
What is still nagging at me though is that when I flush out water late at night, the next few days the quality has improved. I wish there were some way to properly check once and for all if the problem, at least partially, lies in the service pipe. I will get a hold of the neighbours over the next few days, I just haven't known how to approach them about it. I mean when I tell friends about the problem, they look at me as if I've sprouted a third ear!
