I am now officially a very scared person and am madly trying to look at our already stretched budget and see if we cant squeeze an extra $20K out just in case. I would imagine we are going to get the same treatment themex - something to look forward to. Thanks for the details they will be handy. By the way though - we are being told that charged systems are not allowed...... we have an easement at the top and to the left of our block and they wont let us pump up, only down - do you know what your charged line does for you? It is going to be a long and bumpy track this one....... at least we know though. We are hearing stories from other people who find out AFTER their house is demolished and the slab is being laid ML Re: Stormwater and retention issues 4Oct 19, 2009 6:39 am Hi Micklou. Didn't mean to scare you, just wanted you to have any information that I could give you. It all helps face the fire, so to speak. We DON'T have a charged system, the water soaks into the bottom off the pit. Hope it goes ok. SO stressful. Deary me. Good Luck. www.themaxbuild.blogspot.com forum.homeone.com.au/viewtopic.php?f=31&t=20717&start=300 www.leahspaperpassion.blogspot.com Re: Stormwater and retention issues 5Oct 19, 2009 7:30 am Oh OK... misunderstood the 100mm charged stormwater line thingy.... anyway...... it is better for be forewarned and we know what the council can be like after the flood plain / floor level fiasco. I absolutely appreciate all the info and we are prepared for the stress so hopefully we will be fine. Bottom line is that unless the tender comes back within cooee of our budget then it want be an issue. Did you deal direct with the C engineer and council yourselves to negotiate the system - we had an allowance in our tender for a geotech report to get the requirements sorted, but we were thinking we would want to start the easement letter process sooner as opposed to later so we can move through council as soon as possible. We are anticipating that we may have trouble with neighbours now that we are going 2 storey and that can hold the process up as well! ML Re: Stormwater and retention issues 6Oct 19, 2009 8:10 am No, you may NOT have misunderstood. I just asked Dh if we had a charged system and he said no, but I thought we DID::angry:: and the info I gave you is direct from the Tender so I think we do. I will be looking closely at that today in case we don't and there is a $$'s issue there. Hope have not confused you. Sorry We spoke with the Civil Engineer (that's what is on his card) who designs the system and he tried to help us but there was no other way to do it. He was very nice and very fair so if he can help you within Council requirements he will. My DH also went directly to the Council to plead our case, NO GO, not interested. We also called them a few times. There was no way anything would change. We did the neighbour letters ASAP. You will have a different issue though with the 2 storey because I think the Council has to advise the neighbours by mail and they get time to object if they want to. (the same as they did with your single storey plans). Good Luck. www.themaxbuild.blogspot.com forum.homeone.com.au/viewtopic.php?f=31&t=20717&start=300 www.leahspaperpassion.blogspot.com Re: Stormwater and retention issues 7Oct 19, 2009 1:23 pm ML, I am 99.9% convinced that we will be in the same position as you. We have a backward sloping block, with no current stormwater system/easements anywhere. As with themax, our current house is 50-60 years old. I also think it highly probable that our builder will not mention this issue until the last minute (we have paid $4k and so far and not a word). So forewarned is forearmed! Having read this thread, this issue sounds very complicated and I'm going to have to get my head round it ASAP. themax - please can I ask if the figure of $17,500 included the water tanks and their installation or was this additional? Re: Stormwater and retention issues 8Oct 19, 2009 1:45 pm Hrm... I too have a backward slopeing block, but along my back fence is a 13' easement of some form. Can I run my overflow off the rainwater tank down to the easement and let it run on the lawn? What else can I do with the overflow? Re: Stormwater and retention issues 9Oct 19, 2009 1:50 pm Domestic Bliss themax - please can I ask if the figure of $17,500 included the water tanks and their installation or was this additional? Domestic Bliss I will pm you with the exact wording from the Tender so you can see it clearly www.themaxbuild.blogspot.com forum.homeone.com.au/viewtopic.php?f=31&t=20717&start=300 www.leahspaperpassion.blogspot.com Re: Stormwater and retention issues 10Oct 19, 2009 6:37 pm adrian Hrm...

What else can I do with the overflow? Cant say for sure Adrian - but one of the reasons that we have to put the hole in the ground is because we DO NOT have an easement at the back of our block. We have one at the front but that is no good. If your block slopes back and you have one then I am crossing everything for you that you can use it!

Hey DB - looks like we will be in the same boat... getting pretty crowded really isn't it. Then only thing that is keeping us sane at the moment is that EVERY single person who build a new house in the Shire will be subject to this so we are not on our own. Themax is correct i think when she says that it is us that is paying for the crappy stormwater system in this area..... anyway....... Welcome to the "$18,000 hole in the ground club" and I would rather know about this upfront than once demolition is complete - that's for sure! I think our membership is going to expand quite quickly! Good luck and let us know how you go! ML Re: Stormwater and retention issues 11Oct 19, 2009 9:24 pm Same here. I'm on a sloping block, front to back. In a way I am sort of lucky that I have a 300mm stormwater pipe running accross my property so I can put the discharge into that directly. In many other ways I'm completely unlucky for the same reason. I have to have underground tanks in the front as I cannot place them in the back, it is in the path of a major overland flow area. I also cannot build on the stormwater easement and that causes ineffiency in house design. What can I do? Nothing really. You are in for an expensive proposition no matter what. Councils take the view that if you want to develop your property, then you pay. Period. Greg Re: Stormwater and retention issues 12Oct 19, 2009 9:41 pm Hi themax, that was so kind of you to PM all that detail. When you were first presented with that long list, I can imagine you uttered an expletive or 2! I'm sure this KDR process is ageing me - definitely a few more wrinkles around the eyes and forehead already and I haven't even got to council stage yet! Of all the clubs I thought I might belong to, I never guessed it would be a "$18,000 hole in the ground" club! This joining fee will take some beating. Greg - not sure if I've correctly understood but I'm assuming that by underground tanks, you mean your rainwater tanks. Why can't you have the rainwater tanks above ground & down the side of your house? Re: Stormwater and retention issues 13Oct 19, 2009 10:09 pm My rainwater tanks and stormwater detention tanks are one and the same; they are the ones I meant. I cannot have them on the right side of the house because there is not enough room. I can't have them on the left side of the house because they would be in the overland flow path again. I cannot move the house to the left to make roon for them on the right because I would lose more house space due to the diagonal stormwater easement on the left side. Catch 22+22+22:):) My system is two tanks. They are connected together and hold water for stored use to a certain depth. All water storage above that depth is stormwater detention which is released into the stormwater easement slowly. The only thing connected to this system is the roof and two pits. It is a charged system, as the tanks are higher than the lowest point in the system. Greg Re: Stormwater and retention issues 14Oct 20, 2009 4:59 am Nothing like a quick lesson in engineering early in the morning. Thanks for your post gpierce. That has raised yet another issue for us because we are also subject to overland flow so that might affect us as well with respect to where our tank(s) can go. DB - I know what you mean about the ageing thing! Oh another thought. If any of us have any money left maybe we could get a club t-shirt! ML Re: Stormwater and retention issues 15Oct 20, 2009 8:10 am Remember rainwater tanks are different to storm water detention tank. Detention tank costs a lot! I had to have rainwater tanks, 10 cum storm water detention tank, absorption tranches and all other associated stuff! Including all the engineering costs, it came to almost 35K. This is the least quote I got out of at least five! We built this last month. Contact me if you need any info. Re: Stormwater and retention issues 18Oct 20, 2009 12:15 pm $35-$40k I think I'm going to need more than wrinkle cream by the end of this rebuild process ..... perhaps a straight jacket to go over that club t-shirt! Re: Stormwater and retention issues 19Oct 20, 2009 7:05 pm Devank, if ML us in an overland flow area in Sydney then ML can be pretty much guaranteed to have to have stormwater detention. How it is accomplished and the cost for it depends on the specific site and its needs. Whether there needs to be rainwater tanks is determined by BASIX pretty much. Greg Re: Stormwater and retention issues 20Oct 22, 2009 2:06 pm I dont think I have truly appreciated the flatness of my block... nor the absolute lack of any building complications whatsoever... until I read this thread. CRIKEY... 18k for a hole in the ground. pretty sure id just live in a tent if that was the other option lol You just need the gutter and downpipe sizes to be compliant with the NCC for the roof area harvested and have the downpipes connected to a LPOD. You need to ask your… 1 10519 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 9278 Can you post your Architectural and Hydraulic plans so we can see how the system as a whole works? Without that no one will be able to give you any meaningful… 2 1623 |
