Following the Shrewsbury festival recently - when on the main camp site we had a superb new shower block but couldn't use it much of the time (!) I have done some rough calculations for gas and water usage.

I doubt if any or many festival sites provide sufficient capacity - so that everyone can have a shower a day. I've been told about the Towersey upgrade (not before time?). For festivals using large heating plant sized to cope with hundreds of schoolchildren things should work OK, but (out of technical interest) what if any design rules are used for temporary installations? Some people at Shrewsbury seemed to expect 'Caravan Club' standards for their £6 for four days camping!

The rough calcs are here - gas and water usage for folkie showers
