In my backyard i have these 2 pipes that looks to me like storm water drainage. My question is can i connect my down-pipes ( all or most ) straight to these pipes rather than a soakwell? if so this will make everything so much easier and cheaper for me. Thanks Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Re: Storm Water Drainage 2Mar 08, 2020 3:14 pm Hi benimars I assume you are a fellow west Aussie as you are asking about soak wells. I'm pretty sure what you have pictured there is an ORG (overflow relief gully) which is an emergency overflow for the sewer. Is the pipe 100mm in diameter? If it is an ORG you definitely can't discharge stormwater into it. It would go straight into the sewerage system and can cause all sorts of issues and can end up costing you big time. If it causes problems downstream (which volumes of storm water can) water corp will start to trace it back and it can become an expensive problem for you. Unfortunately you just have to bite the bullet and do it properly. Stormwater is one of those things people think they can save money by doing it after the build or at a later date but it's easier and cheaper to get it done at the time of the build.

Re: Storm Water Drainage 4Mar 08, 2020 8:01 pm You probably have one sewer ORG and two dry wastes. If you're down pipes aren't connected to anything then you won't have soak wells installed. It wouldn't make sense to go to the trouble of installing the soak wells but then not connect them to the downpipes. You obviously didn't build the house but have just purchased it?

You obviously didn't build the house but have just purchased it? yes , the previous owner built the house but i guess decided not to do soakwell. could you please elaborate on what the dry waste is for? i remember during our inspection the last owner told me she used to empty out our pool in one of those pipes. Re: Storm Water Drainage 6Mar 08, 2020 10:26 pm Dry wastes are used for floor wastes in wet areas like toilets and laundries. They are just a long length of pipe that runs vertically that the floor waste runs into. They are not joined to the sewer and are just designed for the small amounts of water that may overflow or from cleaning. If they were emptying the pool into it it's not a dry waste. I've never had a pool but I remember when I was investigating it at one point they mentioned putting in a soak well to back flush the filter into so maybe it is a soak well. Or maybe they were just pumping it down the sewer. Is the pipe pictured outside a bathroom or some other wet area. If you run a tap in the house can you hear water running in the pipe. The fact that it is higher than the surrounding paving makes me think it's an ORG Accessible Carpentry & Cabinets accessiblecarpentry@gmail.com accessiblecarpentry.com.au https://www.facebook.com/pages/Accessible-Carpentry-Cabinets/583314911709039 Re: Storm Water Drainage 7Mar 08, 2020 11:45 pm chippy Dry wastes are used for floor wastes in wet areas like toilets and laundries.

It requires permits and from what i understood it has to go like this . OST -> Soakwell ->(overflow) -> Drain channel. Hello I am developing 2 side by side units.
