Water and waste connections for a mobile home on a building site for a self-build

[MariaD]

Hi all, looking for advice on water connection during planning stage in Ireland.
We’re currently preparing our planning application for a detached house on a site zoned residential. While the build is underway, we’d like to live in a mobile home on-site.
The site is close to an existing estate and there’s a water main running around it. When applying for the water connection, should I notify Irish Water about the mobile home as well?

Would that require a separate temporary connection, or can we use the permanent connection intended for the house to connect to the mobile home?
 

Any insights from those who’ve done similar would be really appreciated.

I cannot comment on the sewage as we have a sewage treatment plant, but we simply requested the water company installed a new connection to a temporary building supply.  They came along and inspected the trench a water stand pipe and then connected us up.  Once that was connected you can then take a T off the supply to the caravan and then when ready connect up to your house supply.
