Browse Forums Building A New House Re: Onsite water detention osd costs 2Feb 25, 2020 6:56 pm Depends on the Consultants rate and the designed system. Without actual soil and land survey results, it could be $10k, it could be $200k+ Not trying to be unhelpful, but there is no way of knowing without actually studying the data and doing the design Re: Onsite water detention osd costs 4Feb 25, 2020 10:20 pm tourier No stormwater point on block. Will there be a PSD requirement to a future LPOD? Why OSD? You need to post the council's requirements, whether you will have mains water connection and whether the council requires a hydraulic assessment from a registered hydraulic engineer or whether you can submit the plan yourself. They are relatively simple to do and you never know your luck in Tassie. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: Onsite water detention osd costs 5Feb 26, 2020 5:52 am Thank you, unsure of council requirements, will find out. They are on holiday today. The alternative is get permission from taswater to use their easement and permission from landowner to access storm water point. Would that be expensive? 10 m easement to get to point.

Whilst I understand you are trying to get an idea of costs, I assume to avoid dumping money in before you know whether you can afford this option or not, this is what feasibility studies are for. You need all of the relevant information up front vs answering single points of multi faceted questions. Only a qualified and registered person (with suitable experience) is going to be able to give you an accurate indication of cost. From there, each individual contractor charges different rates and has access to different pricing tiers. My employer gets great rates on most civil supplies, but not as good as someone who only does civil drainage. We do mid rise construction and are considered Tier 2. Tier 1 contractors would be getting even better rates on unit prices, but they're buying tens of thousands of units and we buy thousands. Just getting hold of a contractor who has done similar work will give you more information than anyone can here. If they have done similar work, they'll know how much it costs and the issues that can impact the cost and delivery. Re: Onsite water detention osd costs 7Feb 26, 2020 9:03 am tourier Would that be expensive? 10 m easement to get to point. Ditto to CF Design's last post. Too many unknowns to guesstimate. You have a bare block with no apparent house/site plan. Stormwater drainage includes surface run off and you won't know at this stage the drainage network, number of silt pits etc. I could give you information about how to minimise onsite detention costs if I knew your situation but you haven't provided council requirements or whether you will be off the water grid etc etc. 3in1 Supadiverta.

Re: Onsite water detention osd costs 8Feb 26, 2020 12:21 pm Iām not sure where you are located, but we paid a company approx $1000 to do a report, this provided us with a few options and we could pick from there. Of course we had a draft plan and siting so that we could adapt their recommendations to what suited us. We also did a bushfire report for the same reason. We had an indication of cost and ways that we could reduce cost (such as minor amendments to the siting) which reduced our BAL level. The best thing I can say is do this independently not through a builder, so you can make the decisions. Re: Onsite water detention osd costs 10Feb 26, 2020 7:29 pm Council requirements for this subdivision which was done over two years ago, was that each block.must have stormwater point connecting to public stormwater drain. Each block has H2O, sewer, stormwater point, but this one has not got the stormwater point. There is a public stormwater drain 10m away from boundary. Looked at legislation and council is required to connect all residential blocks to stormwater. Developer was legally obliged to do so.but forgot to (?) with this block. The stormwater point is on the developer's land via easement. Developer has told me I can't access it. Can he stop me? What will be the cost of hooking up to this stormwater point if I am allowed to? Should council or developer be paying for it? Whether I wish to do OSD or not, I have to have a stormwater drain access for excess runoff as developer has said I will be responsible for excess water that falls onto his block below mine. Tricky. Any advice? Re: Onsite water detention osd costs 11Feb 26, 2020 9:23 pm First thing to check would be does your contract of sale indicate there is LPOD on property? If so, developer should pay. If not, can they stop you accessing land they own? Yes, they can. Depending on the work required, 10m connection distance could be $5-20k and that could be high or low depending on what is existing.

Have you contacted the council about this? If not, doing so should be prioritised. tourier The stormwater point is on the developer's land via easement. Developer has told me I can't access it.

He sounds like a real hat. tourier Whether I wish to do OSD or not, I have to have a stormwater drain access for excess runoff as developer has said I will be responsible for excess water that falls onto his block below mine. Surface water OSD would require an underground tank and/or a pumping system. Not a good prospect. Maybe you could make a 'natural' detention pond a landscaping feature on your acre. Legislation regarding overland run off differs from State to State with some States allowing natural run off. If the run off is from a hard surface area or a result of altered terrain, it will be a different matter. You need to check your State's legislation. There have been a number of such threads on the Whirlpool Forums Home Lounge over the years. Maybe wander over and do a keyword search in the Home Lounge but just be aware of the date stamps because legislation can change. Is there a block above you that also has run off to your property and then to the hat's property? I know what I would be doing! 3in1 Supadiverta.

Re: Onsite water detention osd costs 13Feb 27, 2020 7:42 am The developer sold it to someone who we bought it off. There is a block above us that runs onto us. Developer directly below us. Road also runs onto us. that is meant to be a stormwater exit but road is at a higher gradient to block. State legislation allows run off but developer says we will be in trouble if water comes down to his house. Legislation also says in urban drainage stormwater within 30m must be hooked up. The developer has easement on his land it is our sewerage easement (apt!) And that runs to stormwater point public which is 10 m away (all easements on his land). The public stormwater easement runs all the way down side of his land. Can he refuse us access to his easement? Developer has told us where to build (as does not want us building directly above him). Due to run off. Is it expensive to put in a pond? We can dig it ourselves. Simply we don't have much money and can just afford a one bedroom cabin we did not envisage all this I am not sure whether Perth has its own way of doing things in regards to this. Most of Perth has class A (sandy soil), except for some areas near rivers or hills. 2 13106 Looking to tile the facade pillars rather than rendering.
