Browse Forums Building A New House Re: Alternative to charged system moving rainwater to street 22Mar 10, 2014 7:27 am Are you allowed to run charged rather than tanked? The water is still in a charged pipe regardless but the downpipes will have to be a sealed system. I can't see why you can't run charged pipes, certainly a lot easier and cheaper than the builder's now three alternatives. The council appears ok. 3in1 Supadiverta.

Re: Alternative to charged system moving rainwater to street 23Mar 12, 2014 9:09 pm I spoke with a drainage engineer and looks 2 options maybe a possibility. 1) Dry and wet pipes, no tank. Possibly connecting all closer downpipes to a dry segment separate to a wet segment for more remote downpipes. These segments would come together in a small box close to footpath before running to the kerb LPO. 2) Dry pipe and drain to garden. Similar to #1 but with the more remote downpipes to dissipate water underground (we have sand, gravel fill). Apparently the option #2 would be by the rules. I understand there is some reluctance towards wet pipes as they contain stale water. The bottom line is that #1 technically would work and given a single dwelling (house) regulations are light that might be offer the solution for us. Option #2 sounds very interesting as we could water our garden and trees at the same time but it would come to the cost.

We have this on our holiday house and it enables you to flush out any silt in the pipes or leaves etc. Re: Alternative to charged system moving rainwater to street 25Mar 12, 2014 9:52 pm Crazyk could have a screw cap at the lowest point and take it off to flush your system. Not sure how that would work (but think would need it) as our pipes would be underground. Would you dig a pit (with some lid) around the lowest part?

The builder advised we will not need any water tanks and the system will be included in the standard build fees. I understand 100mm downpipes will be used to charge the system. Took almost 4 months but we are still before contract so that was bearable. Thanks to folks who chipped in basic and more advanced input. Greatly appreciated as we are just aspiring new home owners, not experts in building.

Its a 1950s build and the downpipes originally went straight to the ground not far from the stumps. That needs fixing! The roof gutters are about 4.5m above the level of the kerb, BUT the land slopes from the kerb down to the house, so a charged system seems the best option. The kerb is about 80cm higher than the ground level at the front of the house (about 7m distance). I have some questions: 1. the water won't stay in the roof gutters will it? I saw the diagram in the link posted by Bashworth, and I'm hoping that the water level there is shown at time of rain, not the rest of the time. When its not raining, shouldn't the water in the vertical section of pipe be at the same level as the discharge point at the kerb? 2. will silting of the below-ground section of pipe become a problem? Is there something that can be designed into the system to make cleaning it out easier? Thanks Re: Alternative to charged system moving rainwater to street 29Jul 08, 2018 1:25 pm SueMcGoo Hi, I'm having the same stormwater uphill issue with a rental in Qld that I have recently had re-guttered.

That means that if the tank inlet is at half the height of your downpipes then the pipes will be half full of water all the time. I am assuming the outlet of the tank is at the top also.

Is there something that can be designed into the system to make cleaning it out easier? 1. The wet system water level won't exceed the height of the outlet unless the outlet is blocked and a blockage could even be deliberate. To safeguard against this, you should seriously consider fitting air gaps to the downpipes so that the gutters cannot fill. The usual way to install an air gap is to fit mosquito proof leaf diverters, the ICON Leaf and Debris Controller ($38 in Bunnings) is the best currently available. The leaf diverter will also prevent mosquitoes breeding in the wet system downpipes as well as reduce debris entering the system. From egg to adult mosquito takes about 12 days and there can be 400 eggs in a 'raft'. 2. If you have a 100mm PVC DWV subsurface drain pipe, you could fit a DIY sediment trap about 3-4 metres past the last point of turbulent flow (usually a tee) and drain the captured crud when time suits. The smaller drain pipe can also be poly pipe because the reduced size generates a higher velocity flow to flush the captured crud. See diagram further below. This simple sediment trap uses off the shelf parts and was developed during our Supadiverta development program where it was found to be very efficient with smaller faster flowing PVC pressure pipes. It was late adapted to larger PVC DWV pipe wet systems diverted to rainwater tanks and it would also work very well for your situation. NOTE that we now use either a 100mm x 50mm or a 100mm x 40mm invert taper instead of a pipe reducer now. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ 3in1 Supadiverta.

Re: Alternative to charged system moving rainwater to street 32Jul 10, 2018 8:10 pm Oops! I forgot to mention that you need leaf diverters fitted to the downpipes if you install a reduced size sediment trap to prevent lerger objects like dead birds etc blocking the smaller flush pipe. 3in1 Supadiverta.
