Re: Need advice on our rainwater collection and storage syst 17Oct 24, 2012 3:07 pm Following this thread with interest as I am at the same point of making water tank connection decisions. I understand the reasonings behind having a wet system enter the tank at a low point (to reduce the disturbance of the settled crud in the bottom of the tank, aerate the anaerobic zone and to increase the available head) however this means the wet system is fully charged at all times once the water level reaches the inlet height. Granted this makes flushing the system easier as the head in the tank assists with the flushing power. @SaveH20 - Is there an upper limit of tank size before the water pressure exceeds the burst pressure (of joints more likely) of 100mm DWV? I am looking at a single 200KL Rhino tank due to available space and budget restrictions. ie 2x100KL wont fit and are $7000 more than the single 200KL tank. The two issues I have with a low point connected wet system is a) failure of the joints in the 100mm DWV sections. If my 200KL tank is full and the pipe burst or joint failed, I will have 150KL+ worth of flooding! plus the loss of all that precious water. b) the lack of ability to place a first flush device into a fully charged wet system. In my opinion a wet system must have a first flush device fitted just prior to the tank inlet. In times of low/nil flow, the water in underground 100mm components could be very stagnant. However I am unable to envisage how you could do that and still have a fully charged system under tank pressure.

I'm no buff when it comes to the Australian Standards, but surely it ought to also mention the area the gutters "service"? I mean, 100 square meters fed into 10 meters of gutter is quite different than 12.5 square meters fed into 10 meters of gutter. With that said, I will make a compromise on my own build: I'll have square downpipes to match the house, knowing full well they're not as effective as round downpipes. They'll be big, though - I'm thinking 200x300 mm, so two or three of them should be alright for a total catchment area of 130-140 square meters (the roof is almost flat, angled backwarks, so it will run to the back of the house into a single, integrated (hidden) gutter). Re: Need advice on our rainwater collection and storage syst 19Oct 24, 2012 7:33 pm Crikey, a lot to digest there. It's a steep learning curve for me and is certainly a crash course in rain harvesting. Thanks SaveH20, your time in freely giving advice on here is commendable. I'll do some study on the above and reply again with some questions. One thing I haven't been able to get my head around is using the low inlets in the side of the tank. If the tank is even say half full (12,000 litres) wouldn't the pressure of that volume of water prevent any water entering from the wet system? The other thing I'm wondering about is what type of fitting should be used for a low inlet especially considering the Camel tanks have a corrugated side wall profile. I'll check with Camel but they're don't seem to like discussing anything 'out of the box'. Will also check with them re warranty in regards to cutting holes in the sidewall. John P.S. The house kit company has now agreed to supply 3x 100mm downpipes for each of the two awning gutters. Re: Need advice on our rainwater collection and storage syst 20Oct 24, 2012 10:22 pm Great work there SaveH20 (AKA...). I have read your description of the low tank inlet and sediment trap elsewhere and plan to include it in our current build. I had the same query as Rocks regarding pressure/vulnerability of joints and seals and pipes including risk of damage to the inflow pipe leading to backwards loss of water from the tank. Once you know the basics, the rest is easy.
