House Extension on Wayleave?

RyanM1

Good afternoon,

I am hoping to build an extension to the side of my house and have a few questions.

1. I bought the house as a new-build. It is part of a small housing estate (5 properties) built on a greenfield site in County Louth. On the Planning Portal, the proposal for the estate shows the 'Site' as the entire development; as such I am unsure exactly which parcel I own and can build on.
2. Where I am looking to build the extension, there is a 7m wayleave below which is a 150mm concrete pipe in concrete surround. This connects to the existing storm mains in a public path outside the site. From my research, I believe an application would need to be made to Uisce Eireann by filling out a 'Building over or near an Uisce Eireann Asset' form. Is this correct?
3. Who has access to maintain this pipe? Is it Uisce Eireann, or another utility company and are they currently responsible for maintaining it, as opposed to the original developer? 
4. Is it possible to divert such a pipe, and if so, is this costly?

I have attached an image showing the wayleave and a pink area highlighted a rough footprint for the extension.

Any advice is much appreciated. 

Kind regards

Ryan
