Re: Rainwater Harvesting Help 51Apr 10, 2020 10:41 pm Jomo That sounds like a great plan to increase hydraulic head height and gain a little extra in storage ability. It is a technique used mainly for large rural tanks plus they also divert the water off the SD filter via a wet system to a squat tank for outdoor use. I see your main advantage in having additional head mostly being when you have a small fast moving storm cell when the tank is nearly full. Increasing the head 300mm from 100mm to 400mm when the tank is 100mm below full level will double the flow rate. I have given some extra thought to it and I am now thinking that buying the covers and vents may not be worth the bother plus the cover would also need a small vent. An alternative would be to raise SD1 (maybe 100mm?) above the height of SD2 as this increase would not cause the tank to overtop. It is tricky trying to calculate the pipework's flow rate but a conservative guesstimated flow rate allowing for 35 metres of friction loss (worst case scenario) pans out at about 48 lpm with a 100mm head. With an additional 100mm head on SD1, you would be looking at 69 lpm and that final 100mm capacity would fill quickly as I (roughly) figure that each tank would hold about 260 litres per 100mm of height. x4 the head doubles the flow rate but the increase is not lineal. A 1 metre head will generate (worst case scenario) about 168 lpm and a 2 metre head +240 lpm. Jomo What would you recommend for the top vent? Just do a through tank fitting and screw a meshed filter onto it similar to my waterbouy filter? Or should I actively try and increase the height with a length of pipe additionally. Yeah, just a female tank fitting plus a pvc valve socket and a short pressure pipe with some mesh fitted over the top but it could be tricky doing up the tank fitting! Having an extra +300mm head would be very handy though. I like the silicone type of washer as seen on the Holman tank fitting linked below.

Re: Rainwater Harvesting Help 53Apr 11, 2020 12:05 pm When you finish the plumbing, I would leave the balance line shut until you first need to use the harvested water. The minimal 'sediment' in the settling tank will be suspended particles that did not settle as bed load. You won't have to syphon clean the tank for many, many years. You can install the SDs at any time prior to installing the pipe work. If it looks like raining, just wrap a few layers of cling wrap around the filter to divert all water to the stormwater. If you ever need to clean the gutters, do the same but put the filter back in top end first and horizontally under the inlet but leave the other end protruding 2-3 cm past the opening the lid normally covers. Also cover the exposed area below the filter. This will divert all muck from the gutter to the ground. The filter will fit snug because the SD body and filter are both tapered. It is also best to clean the gutters before installing. Have you worked out the flow rate the garden will need and picked out a suitable pump? 3in1 Supadiverta.

Re: Rainwater Harvesting Help 54Apr 11, 2020 12:11 pm Nice will keep those thoughts in mind. Plumbing is pretty much ready to go as soon as the sd's are installed. Can't see the laser point from the level as it's too bright today which was expected, so I'll head out tonight and hopefully be able to see it. Then tomorrow clean the gutters and install it all Re: Rainwater Harvesting Help 55Apr 12, 2020 7:04 pm Had good success after a few attempts - I was lucky enough that one of my downpipes is in a good position to project the laser light towards the tanks.

Made a small cutting error on SD2 because I forgot that it didn't have all the size adapters that SD1 required - doh! Oh well a couple of folds of metal go it all connected up. Waiting for the silicon to dry and then I can attach the dropper pipes and plumb it all in (and finish painting) Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Re: Rainwater Harvesting Help 57Apr 14, 2020 8:18 am Slopes can be deceptive but the height will make cleaning the filter or just having a stickybeak a breeze. I can see you standing there in the rain looking at how it works but don't worry, most people do it. Did you consider leaving the original paperbark colour to be more neutral with the wall? 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

To be honest no I didn't - just thought "I'd better match the downpipe colour to the SD colour" so I painted it 'Manor Red' We do plan to grow vines up the garage wall at some point too, it's a bit of an ugly wall. Re: Rainwater Harvesting Help 59Apr 20, 2020 12:37 pm What a busy couple of weekends I've had. I'm now happy to say that I'm officially at a point where if it rains I'll be catching it in my tanks! See below some pictures of final fitting solutions for the SDs to my tanks.

I'm extremely pleased to confirm that the solution works - it holds the full flush pipes, triggering the solenoid causes it to drain the pipes, and when the solenoid stops being triggered it happily goes back to a seal. The solenoid I'm using is - https://www.bunnings.com.au/pope-13mm-mini-barb-valve_p3130657 Final steps on the capture side are to drill a hole in the existing overflow pipe (where the main body of the down pipes goes), tap it, and put a 13mm barb fitting in there that I can connect with some hose to the outlet side of the solenoid. Wire the solenoid into my controller and setup an IFTTT (if this then that) programming to clear the flush pipes if we haven't had rain for a while. Finally I'll also get some sheet metal folded at some point to cover the drop pipes from the SD and make it all a little neater. I also received the Mk II design of my waterbouy-guard and installed that into tank 2 on the pump pickup line. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ I'm very happy with the MkII design - it seems a lot stronger and was very easy to install. I haven't mentioned the irrigation side of things in this post at all, but I've been planning away for the last few weeks designing that system also - I'll make a followup post on here showing my sprinkler design etc. Thank you so so much SaveH2O for all the assistance you've provided in this thread, private messages, and on the phone. Your expertise and support have been amazing and absolutely key in my project - I could not have done it without you. My neighbour who shares the fence that our tanks are sitting next to asked me yesterday: "so when are the pipes going in?" "what do you mean?" "the pipes from the tanks to your roof" They thought I was going to run 20m of horizontal pipework above the ground from the roof to my tanks. They must have thought my yard was going to be so ugly to look at for the last couple of months The SDs have allowed me a simple, clean and elegant install solution. I could not be happier with the results! I'll also post some follow-ups in regards to how the capture goes, can't wait til we get some rain!!
