seacroft serviced pitch...hose length required?

Hi all,

I'll be staying on a serviced pitch at SeaCroft at Easter and was wondering if anyone had any ideas as to how much water and waste pipe/s I'm going to need. Does each pitch have it's own drain or is it shared between a couple / several vans, never used a super pitch so i really just need a general guide. 

Any help/advice appreciated.

Thanks in advance

Si'
