Correct at August 2006.
Hi All,
I started this last year and never got it totally complete. If I don't post it now I will never post it. Don't know if it has sticky potential, I'll leave that to the mods.
If anyone can confirm any of the blank spots, then pm me.

We do not practice chloramination as such, but some of our raw waters do contain low concentrations of naturally occurring ammonia, and as a result, when these are disinfected using chlorine, some monochloramine is formed. Typical concentrations of monochloramine concentrations in our treated waters would be up to 0.1 mg/l.

80% of water supplied from underground chalk boreholes which contain natural ammonium at about 0.15 mg/l. This is superchlorinated, then de-chlorinated before the water leaves the process for distribution to customers at between 0.1 and 0.15 mg/l chlorine most of which is freely available. This is not chloramination. About 20% of water supplied is from surface water which was chloraminated but has not been for many years. Chlorine residuals entering distribution from surface water are between about 0.3 and 0.6 mg/l.

A number of treatment works in the London area do use chloramination as their disinfection process, including all the large-scale works, which pump into the ring-main. As a result, virtually the whole of London has chloraminated water at varying levels, depending on distance from the treatment works. The exceptions to this rule are small areas around Epsom, Sidcup, Bexley and Dartford, which are supplied by small works that do not practice chloramination. In the provincial areas, like Swindon, Oxford, Reading, Guildford, Slough etc our treatment works do not use chloramination as their disinfection process.

Three Valleys Water does not treat its water with chloramines, however they do take a bulk supply of water from Grafham Water. This water is treated with chloramines, unfortunately as 3V do not chloraminate the water themselves they do not actually test for the specific levels. Three Valleys Water has 70 water supply zones, only one of these in the North of Luton has chloramines in it. Other areas that the Grafham supply reaches, vary according to need.

Part of the Welsh Water area is chloraminated. At present the regions that practice chloramination are most of Anglesey, most of Ceredigion and the area around Tywyn. The general levels expected depend on where in the distribution system you are, but are generally 0.3 - 1.0mg/l total chlorine. This information is correct as of 31/03/06, but they might add more chloramination plants in the future.

The water in the Yorkshire Water area is not generally chloraminated. Only a small proportion of Yorkshire Water sites are chloraminated by direct feed. Unfortunately, I am unable to provide details of which sites are choraminated.
