Legionella / Cold water storage tanks

At my school we have 2 x cold water storage tanks which are situated in the boiler room and are fed directly from the water mains.

The are both currently reading 23 degrees and have been around this reading for the last 3 months. No wonder we can't get a reading of below 20 degrees at the taps [Scared.png]

I'm guessing this will be a common problem with a lot of other schools?

Apart from regularly flushing through the system, has anybody out there having any suggestions? We are due a Legionella risk assessment at the end of this month.

I would get a copy of the recent weather temps. and keep it with your readings. Also, you might want to look at insulating the tanks to help keep them cool.

I'd be pushing for the tanks to be remover and run the taps directly from the mains supply.

I was having the same problems with the incoming mains temperature, our water treatment company said it was the extreme weather we are having and the water authorities are allowed to supply water up to 25c.

It would cost too much to have the tanks removed bro. Hooking the taps up to the mains is simple, but you also have to look at the water heaters and low pressure (heating) systems. Reduced pressure valves would have to be installed and they can be a pain.
