I think more background info is needed - for example what is the water for, is there back up to mains water supply that requres isolation
- are there pressure vessels, multiple valves and autostarting pumps,air pressure and quality monitors and level switches and a UV steriliser to consider, or at the other extreme is it much more basic than that, and just a single submersible pump in a well used to fill a cistern in the roof that's only used to flush a single gravity drop to a WC anyway ?
I think without that level of introduction we can only guess what you might need, as it may be anywhere between 3A RCD protected spur off the nearest socket, right upto a special control panel with PLCs and 3 phase ;-)

Most tend to use a submersible pump with sometimes a solenoid valve to allow tap water to top up the storage tank. The plumbing side can vary a bit (the complication is the water regs being a bit paranoid about the risk of backfeeding 'impure' rainwater into the potable system). Most manufacturers supply a 'control box' that itself probably only needs a fused supply. As a mixed discipline system I guess your first job is to decide who's going to do which bits (e.g. the cable between the control and the pump - is that you or the rainwater system installer?)

The above will give you a overview of what is likely to be required. Whoever specified the system should be able to advise.

Depending on the job I quite like doing some of their legwork - for a price.

New builds are protracted jobs and it is easy for lines to get blurred as to who does what, so keep it well documented and bill weekly or fortnightly.
