Hi,
I am building on a block of land that has an easement on it containing a 300mm sewer pipe. The builder has advised me that the pipe is 9.8m deep, and we therefore require screw piles in the slab to provide extra stablity should they ever need to dig up the pipe. This has resulted in an extra $10,000 of site costs.
The builder hasn't provided anything from South East Water confirming the pipe depth, they've just written it on the plans. Is it normal for a sewer pipe to be nearly 10m underground? It seems like a hell of a long way down!
I've put in a request with Dial Before You Dig, but need to get back to the builder ASAP as they have the site cut scheduled for this coming Tuesday, so was just wondering if anyone else has had experience of a sewer pipe being this deep underground on their property?
Thanks,
Michael
