As of now, very few buildings have separate grey and black water plumbing. In the event that you did have separate plumbing in the building, you would need separate plumbing in the street as well.

Unless you live in a very water constrained area, it's pretty unlikely. In the US, plumbing for reclaimed water is available in some areas (purple pipes), and seems like an easier intervention, it's often used for landscape irrigation, which has easily accessible plumbing to retrofit. It can be used for toilet flushing as well, if that is plumbed separately from other fixtures in the building.

Can you irrigate with water that has detergents in it though?

Yes, depending on the detergent content. Reclaimed water is usually water that's been treated for pathogens at the treatment plant, but hasn't had been through all of the post-treatment cleansing required before discharging into waterways.
