Re: A House with 2x5230 lt Rainwater tank !!????? 6May 14, 2016 11:59 pm Thanks for the reply guys Stewie D It maybe a requirement of the council but I'd say it is probably more a requirement to comply with the water component of your BASIX certificate which is needed when you lodge a DA. $5,000 for an OSD is cheap too. Stewie This is the first time I heard about this OSD, EBH didnt mention me that this OSD is required for the Fairfield council to approve on my land. If only they did, then It wouldnt shock me like this. SaveH2O They quote $5,170 for the hydraulic assessment, excavation, pipes etc and a total of $8,765. I surmise that the $3,595 additional cost is after a deduction ($1,585) for the original tank and some plumbing allowances Vs the cost ($5,180) of the Modline tanks. The variation as posted lacks vital detail and is disrespectful the way it has been presented if that is all you got. Most of the cost is with the hydraulic assessment and the excavation. I also assume that a tank had already been costed. The excavation could be for trenching (pipes) but surely that would have already been costed with the original tank but I also note that they don't mention the two concrete slab bases yet only one would have been prior costed! Just a note: I have looked at many hydraulic designs on this forum and only one has been correct so far. Don't assume that yours will be ok. EBH first asked me to upgrade to a slimline tank for $1328 ( it sad that, they didn't deduct my original one that they provide, its like I was buying a brand new slimline tank ) , then when they have this hydraulic assessment , they just send me this PCV asking me to upgrade these 2 tanks plus a few things else at a total cost of ~$12,000. What I post was just half of the PCV . what you meant was it is not going to be a final cost for this OSD system, is it ? @ Bashworth : It is shocking me when I found out someone in castle hills paid $48,000 for this OSD system. wow. Again guys, how do I know if this OSD is a must for my building ? Is there any other way to avoid it ? its really outa my budget now . Thanks a lot.

If only they did, then It wouldnt shock me like this. You're not listening to what I am saying. The rainwater tanks would have everything to do with your BASIX requirements and nothing to do with the council. Have a look at your DA documents. Your BASIX Certificate No will be printed on your plans ( should be on every sheet ). The major components of which should appear on the relevant drawings like elevations ( window frame type, glass, awnings etc ). The OSD tank would be a council requirement and nothing to do with BASIX. Once again it should be part of your DA documents. Our council ( Warringah ) requires that once the proposed hard surface area ( impervious area ) of your block of land ( roofed area, paths, driveway etc ) increases on a site by more than 35% of the existing then OSD is required - either a basin or tanks. I'd say yours would be similar. The size of your OSD is worked out according to this proposed impervious area. Stewie Re: A House with 2x5230 lt Rainwater tank !!????? 8May 15, 2016 1:16 pm Your 'detention' tanks will almost certainly have retention and detention 'compartments'. It would be very unusual if you had one dedicated detention and one retention tank. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: A House with 2x5230 lt Rainwater tank !!????? 9May 15, 2016 5:15 pm Thanks for Rely Stewie and Save H2O I'm a newbie in this building industry, so there are a lot of things I that I don't know, so it was a bit surprise for me when I got this bill at $9000. However, after got some advices from you guys, seems there is nothing I can do but accept the quote. Thanks a lot for helps Cheers Re: A House with 2x5230 lt Rainwater tank !!????? 10May 15, 2016 8:21 pm You should arm yourself with some knowledge gleaned from these pages and other sources. There is a lot to learn from your council by downloading their LEP and DCP which covers most of their guidelines for DA's - setbacks, height etc. Then there is the NCC which is freely downloadable which covers most of how a house has to comply with federal guidelines for actually building a house.
