I live in Perth in the Hills and am building a new house on a subdivision. The shire want all storm water retained on site however it is clay with 800mm of fill and won't take soakwells, hasn't got a shire drainage I can plum into and the block is sloping away from the road.
I've been told I need a civil engineer to design a system to put to the shire for approval.
Has anyone had this scenario.
Thanks in advance.

I know of people who bought a block on the low side of the road and when their housing plans were lodged for approval, the council planners directed all stormwater run off had to go into a retention tank and then get pumped back up to the road. It cost this young couple approx $14k to get this done.

Hi Kevin 1, if your using a builder they would (or maybe I say SHOULD) price the stormwater engineering as part of the scope of works, don't go to a civil engineer, someone like Structerre or Enginuity Engineering can do that for you, and won't cost a huge amount.

Thanks for the references Doozer, I'll get in touch with them. I'm trying to save on site works and am still getting quotes through a building broker at the moment, however it was prompt engineering who did the soil testing and reckoned a civil eng needs to look at it. Rather than it be over engineered I'll try your suggestions. Thanks
