Probably up around 5k will be fine too. The settling tank will need to be larger to accommodate the inflow, if not, you are restricted to either pumping to the 90k tank or else overflowing somewhere. Much easier to have a larger settling tank with good mitigation. ![]() "This would obviously be supplied by a dry pipe infeed but do not have the top meshed inlet above the outlet that supplies water to the bottom 2,000 L tank. This may sound obvious but I see this mistake all the time." I am a little confused by this. Are you saying have the inlet from the downpipes to the large tank lower then the outlet?? No. What I am saying is that if the tank's top meshed inlet (where the water falls in) is fitted above the bottom outlet valve that will supply water to the number 2 tank, the water falling in this area will stir up any sediment when the tank's water level is low. It is better to have water falling through a tank's top meshed inlet that is well away from that area. Actually, the water level doesn't have to be all that low for it to cause sediment resuspension due to the generation of impacting toroidal vortices. I can post some information about this subject if you like, it is quite fascinating. With regards to the outlet valve, a lot of tanks have the valve that supplies the pump fitted very low on a tank which then draws the worst quality water and any suspended sediment from the tank. It is a common yet obvious fault. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ ![]() I am thinking that you are saying to have solenoid valves between tanks 1-2 (located closer to tank 2) and also another solonoid valve located in between tanks 2 and 3? Is this correct? Do you have recommendations for a solenoid valve and/or floats? Topaz had a nice small valve that operated with low pressure, they might still make it. There are different valves, the one fitted to tank 3 just needs to supply a water level that is no less than 200 mm above the valve that supplies the pump and the tank 2 settling tank level should be a bit higher than tank 3. I prefer a set cut in and cut out height because it gives a good continuous flow through the pipe but that may perhaps be a bit pedantic. The required mitigation capacity of tanks 2 & 3 will determine the cut out levels to a large degree. EDIT: Most solenoids need a minimum 20 kPa pressure to operate but maybe there are some new ones that don't. I think that a manual valve is the way to go but you need one that operates on very low pressure. The critical one is tank 3. 3 in 1 Supadiverta. 0.75mm filter. No downpipes diverted.
