Appreciate the help all. This is a great idea, thank you.

I'm getting nowhere searching and translating Pantip plaza and I could use some help. The municipal water is always shutting off and I want to install some water tanks and a pump. Everything on my property is unfortunately ½" pipe. From the tanks to the pump it will be a 1" pipe that will then need to be reduced to attach to the house. The house is a single story with 2 bathrooms, a kitchen and a laundry. We have a large garden that gets watered everyday. The concerns and questions I have are: Does reducing the pipe size mean I need to be mindful of how powerful the pump is? (I was thinking a Hitachi 250W but now erring on the side of a 150W/200W) Can I reduce the pipe size soon after the pump? (there are pavers surrounding the house that will make replacing the existing ½" pipe a nightmare of a job) Would it be better(safe?) to just reduce the inlet and outlet of the pump? I've attached a rough diagram that shows I have a dedicated pipe surrounding the property for the garden and the mainline that will connect straight to the house. Any help would be appreciated immensely. Thank you.
