This is just an idea I've been kicking around lately for my next system, a lot of people bury IBCs or other tanks for a sump which takes up space. I was thinking if you're building raised beds you could just put 55 gallon barrels on their sides under your GBs and link them together, burying 2" pipe as needed to tie them all together as your "distributed" sump using space that would be wasted anyway.

Benefits would be:

1. Less wasted floorspace / recovering space that would be wasted under the GBs.
2. Pump with less head rating can be used versus a buried IBC = electricity $$$ savings (probably not a lot though) or better for solar?
3. Just burying some pipe a few inches deep if needed versus digging a giant hole for IBC :)

Of course as with anything there are a couple of potential issues:

1. Probably would want to add lattice or skirting on the GBs to keep the barrels from being knocked around potentially causing leaks.
2. Would want a pump pulling water from and/or GB draining in to each barrel to avoid stagnant zones.
3. Depending on your local market, potential cost of multiple barrels vs an IBC.

Hi LowCarbTNPer, seeing as no-one responded...

yep it has been done around here before where people don't want to dig in.
Similarly using 2 half or 60-40 cut IBC's.
The approach solves the volume issue no problem.
Its limitation is keeping a depth of water over the pump.

With IBC's the 60-40 works OK as you can put the pump in the lower IBC.

If you used the barrels you would have to consider the same.
One option would be to have 2 barrels on side and something at end with pump in it.
You could even have 4 barrels 2x2.

As you note it comes down to relative costs of barrel vs IBC.
Each barrel is around 200L (44Gals) so 4 barrels = 1 IBC.

I haven't actually done it yet, just an idea I'm kicking around. Hopefully they would be all on the same level surface and laying on their side unless your GBs are really tall, so you could easily fill them 3/4 full or more so shouldn't have any pump issues. You could definitely have an external pump hooked to one of them or directly to the 2" linking pipework for sure.
