Can anybody indicate how much should (adequate range) the Hydraulic Eng job cost? I understand the intricacies of the work hence the "range" in the question.
Cheers
$33k for mine
$5.5K for mine but we were lucky as we have an existing storm water pit on the back boundary so the cost is just for extra downpipes and to run the underground pipe work from the house to the existing pit (about 40m or so) and connect to the pit.
