Re: Rain Water Harvesting & Fire Fighting Water Tank 10Jul 28, 2020 12:50 am SaveH2O Huggies Tank A is an existing tank. I don't know how old it is but I can find out. Last time I looked, there were various tubes attached to it so it must have been used then disconnected when the old house was torn down. As far as I can see, the exposed tubes were capped to keep them clean. If you post a photo of the pipes you see at the tank, I will be able to give my opinion as to what they are. Huggies I've asked the builder a few times about connecting this tank to the downpipes but I think it is too hard for them. If the builder was to reconnect to the tank, they almost certainly would want to lay their own wet system pipe. There is a decent slope to the tank and an overflow pipe unfortunately cannot flow uphill. The builder may also be concerned about the legality of the overflow discharging to ground but as long as the overflow doesn't impact on a neighbouring property, it will be fine. Huggies I am meeting with RFS (Rural Fire Service) Community Engagement Officer onsite tomorrow How did your meeting with the RFS go? What was their opinion about an underground tank? Underground tanks are expensive plus hooking up a Storz fitting to one would prove let's say 'interesting'. Huggies I don't quite understand your comment "the overflow serving the basix tanks and landscape tanks must be equal or greater than inflow", A common issue with water tanks is having an overflow outlet that has less discharge capacity than the inflow capacity during heavy rain. One way to safeguard against this is to not have a flow restricting meshed overflow outlet that are also prone to blocking. This can be achieved by having either a flap valve or an air gap that is fitted with mosquito proof mesh in the vertical section. https://rainharvesting.com.au/products/ ... ap-valves/ https://www.rainharvest.com/rain-harves ... taag99.asp Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ The mosquito proof overflow mesh will typically have an open area of about 53%. The tank's overflow rate at different heights above the invert must still be calculated (or known) so as to know the maximum inflow rate which must be less than the tank's overflow capacity. It is a widespread industry failing that tank manufacturers and plumbers don't know what they should know. Huggies Your comment about installing a leaf diverter, a sediment trap and a low restriction inlet is good advice. Are these best done by the builder or can I do it later after handover? The builder wouldn't use anything that is outside their supplier network, so I have to install the ICON Leaf and Debris Controller after the house is built. Leaf diverters are essential for wet systems but most are poorly designed and don't even consider having a once popular basket type. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ The low restriction inlet only requires an additional inlet about 100mm above the bottom of the tank and this can be optioned. 40mm or 50mm are usually chosen. It only requires a flexible coupling fitted to a ball valve (hard connections are never recommended due to ground movement) but the wet system pipe ideally needs to be DWV, not stormwater. It is very easy and quick to plumb. The H1 thread installation I posted previously has one plus a sediment trap. The sediment trap only uses a few off the shelf pvc fittings but it is much easier if it is plumbed when the wet system pipe is laid. It is well worth doing because it prevents the sub surface pipe building up muck (the bane of wet systems), improves the water quality and the tank will have much less sediment. It is quick to do and I can't see a problem with the plumber fitting a few additional standard DWV fittings. HI SaveH2O, I want to ask you about a couple of quotes I've received from the builder. Are gutter and leaf guards important? They were not included in their original price. When I asked for a quote, they quoted nearly $9000. I don't know how much these things cost but $9000 sounds like a lot. Is it a reasonable price or am I taken for a ride? The quote for the underground plumbed in 10,000L tank came in at more than $23k. I knew this was going to be expensive but does this sound reasonable? I can send you a breakdown if that helps. I am now inclined to just do an above-the-ground tank with static supply (not plumbed in). TIA. Re: Rain Water Harvesting & Fire Fighting Water Tank 11Jul 28, 2020 8:05 am Huggies Are gutter and leaf guards important? They were not included in their original price. When I asked for a quote, they quoted nearly $9000. I don't know how much these things cost but $9000 sounds like a lot. Is it a reasonable price or am I taken for a ride? A builder will use someone they know plus add on their usual 20% for something that you can have done post build. Unless you have a significant leaf and debris blockage problem, I would steer clear of gutter guard for the following reasons: Half round gutters have superior flow and flushing characteristics. If you want the best performing gutter, these are the way to go. Gutter guard is effectively a very low angled filter.....not a good design choice! The gutter guard with small holes is prone to trapping small organic matter such as tiny flowers and is high maintenance. Been there...done that! Gutter guard disrupts the natural fall of water off the roof which has a back flushing effect during initial heavy rain. This causes a greater amount of sediment to build up. Organic sediment build up promotes rusting in metal gutters due to metal atoms becoming positively charged when ionisation causes their atoms to lose their electron whereas organic sediment is negatively charged. Gutter guard requires maintenance and should be fitted with easily removable access sections but this design necessity is a rarity. Having to climb a ladder to remove gutter mesh can be dangerous. I once had to remove LeafBusters mesh by climbing a ladder on the steep side of the house and removing screws holding down an alloy strip on the gutter edge only to find that it was also siliconed to the gutter edge. After I had finished with the cleaning maintenance, I had to replace it all and that was only the first section. If you have a rainwater harvesting system, you should have leaf diverters fitted to the top of every harvested downpipe to not only prevent muck building up in the underground wet system pipes but to also to prevent mosquitoes and other pests from accessing the standing water. It is mandated in most northern regions for mosquito proof leaf diverters to be fitted to all downpipes serving a wet (charged) rainwater collection system but it should be mandated everywhere. The ICON Leaf and Debris Controller (what a mouthful) can be ordered at the Bunnings special orders desk because Bunnings deal with Icon Plastics. They cost $38 each and can be fitted post build.

There is a lot more work involved when plumbing an underground tank plus the tank itself is invariably more expensive. There is also the overflow consideration. Just have a tank that you can fill remotely when first and later needed and don't worry about the overflow plumbing if you do this. 3in1 Supadiverta.

Re: Rain Water Harvesting & Fire Fighting Water Tank 13Sep 11, 2020 5:37 pm Hello Huggies. We are in the gutter guard and gutter cleaning business ourselves. Another option for better water flow is just having extra downpipes. But if you do decide with gutter guard and want a cheaper option that is easier to remove when its needed check out our Triple-G system! https://graysonsgutterguard.com.au/gutter-guard-install/ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Grayson's Gutter Guard 2/4 Glen Street Hawthorn 3122 VIC Can a plumber put a tap on a rain water tank which is full?
