Browse Forums Building A New House 1 Dec 19, 2018 3:39 pm Hi Did a bit of research but was unable to find much. I'm building a house and would like to know how much Stormwater connection from the house to the street should cost. My house is 5-6m from the curb and is about 21m long. Any info appreciated. Re: Stormwater costs 2Dec 20, 2018 8:07 am Is your question about the entire stormwater retention system, or just about the connection from the end-point of that system to the street? Because just the connection to the street is going to be close to nothing in terms of overall build costs, but the entire retention system can be from a few hundred up to tens of thousands for a normal-sized block; depends on slope of the block, council rules, most-likely other stuff I don't know about. To give an example, a mate in the same council as me had a KDR done on his block which is perfectly flat except for being fairly steep at the road; he had to spend around $30k just for his stormwater system. Our block has the same amount of slope front-to-rear but it's gradual, and ours was included in our "fixed site costs" of ~$40k total, so ours can't have cost anywhere near what his did (plus our rainwater tank is underground & doubles as a stormwater retention tank - I'm told that design saved us a 5-digit amount of cash).

Just from the downpipes to the street. Thanks for the reply. It's one topic I haven't been able to find much out on. I presume it's digging a ditch, laying a pipe, then connecting the pipe to the downpipe and street. Any idea what that should cost? Re: Stormwater costs 4Dec 20, 2018 9:55 am Short answer is: I can't answer your question. Long version, though; you say downpipes, do you mean the downpipes from the gutters? If so, are you totally sure you don't need an entire stormwater retention system? Ignore me if you're sure; but if you're not sure, then I could describe my mate's ~$30k of "stormwater retention system" as being the (complicated) connection from the downpipes to the street. Re: Stormwater costs 5Dec 20, 2018 10:31 am Ha. Appreciate the response Forg. Nah just a simple connection involving a trench and a pipe. Builder has quoted a relatively small sum to have it done before handover. I presume it can be done cheaper, but trying to work out whether it's worth the hassle or not Plumbers 'can be' plumbers, made all the worse by self certification which the building surveyor invariably accepts as proof of compliance! The good thing is that you know know. 3 4859 Grab a hose, insert it at the top of the inlet/down pipe and turn the water on and see where the water is escaping from. Then you'll know. 3 8465 in the stormwater pit or the drain? Those dont look like theyd fit in the drain. Separately, the pits do get stuff in them during the course of the build.
