    My council is asking for a soil/geotech report to ensure that we can dispose of storm water on site, and don't have to connect to the town's storm water network.

    Does anyone have any recommendations for geotech engineers? The report I need is generally about 15-20 pages long.

    NFI where you're located or where the project is so my Condobolin geotech may not service your Elizabeth property.

    Prompt Engineering (go the small guy) or Structerre (do most of Perth).
    Both can do a soil classification and ascertain the soil type and then the appropriate soakwell design based on the size of the roof. However most designers can also do the soak well design as part of their service.

    He's around but he's changed name and I can't get search to find it. It's something like CAD_engineering_drafty_guy

    Structerre (in Perth) gave me a good quote. Work must be quiet, since it is half the price of a similar job they did 2 years ago!
    Smaller companies will be able to do it cheaper though. Another price I got was 20% cheaper.

    Thanks all. Yes, work is quiet for geotechs. I will shoot off a few emails. I assume they are all similar in terms of quality?

    Pistonbroke - I put PER in the headline - short for Perth. Apologies if it wasn't clear.

    Thanks Myf. According to council, if I can't dispose of storm water on site (i.e. due to clay soils or other unfortunate issues), then I need a drainage design. Otherwise council will be happy just with the geotech report backing up that we can dispose of storm water on site.

    I actually re-read the council email and it seems that if the soil classification report comes back as sandy, then we don't need any drainage design etc.

    Consultants seem to be trying to sell me a full geotech report. Is there any value to be gained in getting a full geotech report as opposed to a couple of borehole tests?

    Council say this:

    Which leads me to believe that all I need is a soil classification...

    Which Suburb?

    First you just need to find out what class site it is. You could also phone the likes of Structerre with your address and they'll be able to give you a fair idea what class it is. Close to river could mean clay. Some suburbs are predominantly clay and some sand etc etc.

    Structerre mentioned that their tool shows its sandy. Im not close to the river at all.

    It's in Bassendean.

    UTS Soiltech, around $600 I think for a soil classification.

    Yes Bassendean away from the river is mostly sand. So in that case you will only need the soil report and soak wells will be sufficient. Your builder can do this as part of the contract if needed.

    How much more is it to connect storm water to the main sewage/drain pipe rather then disposing onsite via soak wells?

    It's close to $12k for hydraulic engineer design, geotech report and council fees.
    Builders fees for soakwells and installation is extra.
