Irish water connection from new build

silverwood

I’m currently considering buying a site. It’s in the very early stages. The site comes with outline planning permission. It’s on a main road and the council sewer and mains water pipes run straight down the road directly outside the site.

On the outline planning permission drawings, the waste water pipe coming from the proposed dwelling goes straight into the main sewer pipe on the road (and also the mains water connection is connected directly outside too). However, I’ve heard that you can’t do this and you have to connect into an existing manhole. The nearest one to the property is about 50m away and would result in a significant charge from Irish Water.

Obviously when I appoint an engineer they would be sorting all of this but I’m concerned about a huge unexpected bill from Irish Water should I proceed with the purchase.

Another person told me that for a one off house you can go directly to pipes outside and only developments have to go the manhole.

Anybody know what’s correct? Thanks in advance.

I think you need a boundary trap, aka a manhole , between you and the main sewer to break the house sewer from the pressure in the mains, which could be negative and empty your traps, allowing foul sewer fumes back into you house.
Some discussion on it here, not quite your case.
