Hello everyone,

factory will have to have a steady, reliable supply of water and electricity.

Factory is to have a steady, reliable supply of water and electricity.

Which one sounds better? and why?

Thanks.

They both need to begin 'The factory...'

Your sentences have different meanings so the context will have to determine which sounds better.
