Goedemorgen,
Apologies for not writing in Dutch as I am still not good enough to do so but feel free to answer in Dutch as I have been lurking this extremely useful forum and can read Dutch well enough.
We have bought last year a house in Scheveningen (house from 1930s) and will do some heavy renovation as the person living there before had not done much.
Main issue being the lead pipes - entire piping of the house will be redone - but my question is related to the sewage line (riolering).
Currently the main sewage line runs against the wall of the basement 15/20cm high above the concrete floor (no crawling space). So it takes quite some space.
The plumber advise to have it changed as it is the original in lead, and in not so good shape (you can see various places where it has been fixed/leaked).
It runs straight to the street exiting the house and running under the garden (I suspect it is straight as the street sewage line is in front of the house about 15m in front).
As we intend to install a full bathroom and kitchen in the basement we would like to have the installations at floor level - currently there is a small shower (no way a Dutch person can stand there the shower height is 1m70) and toilet elevated in order to seat on top of the main sewage pipe so that gravity makes its magic.
I had the idea that we could bury the new sewage line in the concrete but of course - it still needs to be higher than the sewage line in the street.
The basement is sitting about 4m above NAP, and I know that the street main sewage line running under the road is about 2m50 deeper than our basement.
But of course the issue is more with the sewage pipe running from our plot to the street sewage pipe which I suspect is "simply" lined up with our side of the sewage pipe running under the garden. So of course I can replace my side of the sewage line (we have to dig the garden anyway to move the water meter to the house and remove the lead pipe) but am I correct that there is nothing that can be done on the street side, and of course, the city would not change/lower its connection from my plot to the main street sewage? Or could I request it?
(I do not know if there is an onstoppingsstuk installed).
I know that on my side the sewage line under the garden is about 1m50/70 under street level (based on the house sewage pipe running towards the garden)
I wanted to know how the connection between my plot and the street side look like to know if by any change there was a drop allowing me to lower my side but the below website stops at the street sewage and does not show the rest of the connections. Is there a resource or somewhere I can ask for more info on that?

I guess I could still dig my garden but that will not help to see how it looks like on the other side.
And of course perhaps could the only solution be to install a rioolpump for the entire house evacuation to lift all up to the current sewage height (in front of the garden so that we still have the sewage pipe in the house in the concrete floor).I suppose that for that I will need a good advice from a professional as the house is relatively big and we are 5 in it.
Thank you for your help, it is a little bit difficult to gather the right information as I am new to this whole owner thing especially in a foreign country).
