Browse Forums General Discussion 1 Feb 16, 2015 9:02 pm Hi all, We are trying to locate our nearest stormwater drain and were wondering if anyone could help identify what the below pictures are and whether any of them are stormwater related. Images below: Image 1 Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Image 2 Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Image 3 Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ I believe the below image is our sewer line. Just wanted to check that they wouldn't generally have access to stormwater below the same lid. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Any help would be appreciated. Thanks.

Fire Hydrant 3. ???? Possibly valve on water main 4. Generally sewer manhole. Very occasionally these may be stormwater but very unlikely In general surface water manholes are generally rectangular concrete, more like a paving slab.

We are going to council and seeking a plumber with a camera to try and find our discharge point. The council plans don't show anything for stormwater for our house or those near us. We are looking to build and builder is saying we need to pump stormwater uphill to the road which will cost a very hefty sum!

We got the below stormwater map through Dial Before you Dig. Our problem is that we are number 11 inside the green circle. The road in front of the house is uphill and the land slopes from left to right. As such, the council have advised that our LPOD is the point in the red circle meaning that we would have to pump water uphill to the road and then build a connection point down to the red circle. Based on the map it appears that no houses next to us or behind us have access to the stormwater system without having to incur massive expense to pump water and build new pipes on council land.

Why? Because the first thing in a storm to go is power. Then how will you pump? The charged water system is good also, except you can't generally have grated drains in front of the garage.

Why? Because the first thing in a storm to go is power. Then how will you pump? The charged water system is good also, except you can't generally have grated drains in front of the garage. Not mention the cost!!! This may be a naive question but doesn't the charged system also require a pump? Below is what we are bring told by the builder: "Today I have received detail regarding the stormwater connection for your proposed build. Unfortunately there was no current connection point to the rear of the property meaning we will need to run all stormwater out to the street. As discussed during the appointment, this would then mean the use of a charge system to be able to pump the water out on the incline to the LPOD that will need to be created in the kerb and channel. We have also been advised that we would need to then create a connect point from the new LPOD to the existing stormwater pipe in the street, which is located at number 5. The advice from estimating is that we would be looking at about $25k but there would be potential for this to increase in price but could come down in price." None of this is appealing Knockdown and rebuild - Sahara Q2 with Henley https://forum.homeone.com.au/viewtopic.php?f=31&t=75715 Stormwater drains 12Feb 22, 2015 9:22 pm It's my understanding that charged systems work on the basis that all downpipes drain into a water tank. As the water fills the head pressure on the tank overflow pushes the water to the street. None of this requires a pump. A pump is connected to the tank and grey water used to flush your toilets etc. With respect to the drain at #5 I'm not sure what they are saying other than they will run a pipe to the street from your house and then run another pipe under the street or nature strips to a barrel drain at #5. Yes this is very expensive and $25k is probably about right. It becomes a big project to do that because you are excavating a trench 4 houses long. Downside is that your neighbours will love you for it because they will just connect into it for free. You've done the hard work.

Re: Stormwater drains 16Feb 23, 2015 6:21 am The best you can do is to request LPOD from the council, pay your fee and then you will know for sure what you are faced with. I am sure that natural drainage(without pumps) would be provided in subdivision. Where are your easements and what do they show?

Where are your easements and what do they show? In new subdivisions yes. . . but in old subdivisions (where knock down and rebuilds are common) there must be tens of thousands of blocks without drainage connections.

Re: Stormwater drains 18Feb 23, 2015 9:53 am SaveH2O, that is one of the drawings that I submitted to our local council as part of a DA for an extension ( it was done by a hydraulics engineer ). This was a big embarrassment for the council as they allowed the original house to be built in the '80's without considering stormwater discharging from the roof. I don't know why that thread was deleted either??? I can't find it at all.

Hi Stewie, I thought that it would have been a basic concept sketch, that's why I was keen to see the thread and see if there were any other sketches so I could run some calcs. The sketch doesn't show the tank's primary discharge outlet's height or size, only the overflow outlet and height. Also no reference to pipe sizes, PSD etc. I am assuming that there was an applicable PSD, otherwise it would have been simple to run a sealed system with air gaps to the kerb. 3in1 Supadiverta.
