Thread: building a shed over sewer pipes?

Hi all,
As every man needs I am looking at having a 7 x 7m shed / workshop built in the back yard. Problem is Ive looked at a site diagram of the property and there is a main sewer pipe running about one metre underground pretty much under the location I am intending on building. Ive looked into the prospect of council approval, and pretty much know I will be knocked back, so am therefore not heading in that direction. I understand building over a main pipe like this would probably be a no no, however it is the only location I can build. What are the odds of ever having to dig under here to get to the pipes. Would I be taking a big risk by going ahead? If Ive okayed the building with all the neighbours what are the chances of council finding out? Im looking at an overall price of $10K, slab and all, and would hate the thought of ever having to demolish it. Any thoughts on this dilemma?
Regards,
Mickem
