If you already have a pump then why not use it to do occasional transfers from water butts on the house drainpipes? That would avoid having hoses lying around on a semi-permanent basis and gives you more water storage capacity. It also takes away any worries about dealing with overflow from the IBC.
Thanks but you lost me. Why would I want to move water from the tank to the pipes? It's the other way that I'm interested: movign rainwater from the pipes into the tanks. Yep, I'll also have a pump, but for feeding the water from the tank to the veg (gravity is not enough).
My gut feeling is that during a downpour the house downpipes will overflow as the water wont be able to move through the underground pipe quickly enough to cope with rainfall. I might be 100% wrong though
I think this is wrong. If/when the water no longer goes into the tank via the hoses
Got my yearly water bill calculated on the exact amount: 193qm, and ca 900eur of water!!!! Wow. I knew I used much but didn't think of such high cost.
Bought via a farmer on ebay two IBC 1000l black tanks. I'm excited now desining the system to feed the tanks from the roofs of house and garage and shed, and feed the plants from the tanks via hoses and timer and pump. Last year it was huge fun watering the tomatoes and the lawn. But it took too much money and time. Better be smart next time round...
Good grief! we use 90m3 and I am watering 2 pollytunnels. 2000 strawberry plants and a 2000m2 vegetable garden! Ok we only need to water for a few weeks each year but still.
think about which pipe you will use as well, you'll need something around the 3-4cm Ø range or you won't be able to get water down it that distance at all.
Domestic water pressure is around 1.5-2bar and that will push water down
about 30-40m of standard hose before you notice a drop in pressure at
the end. 1m gives 0.098bar... so the distance it can push is much
shorter.
I really think @Hostafan1 has it right with the rain not being able to get through the pipe fast enough.
