Water Tank install for Rainwater Harvesting (Eco Tank)

I swapped out an old water tank and installed a new 1300 Gal (5 000 litre) rainwater harvesting tank. We are in a drought so collecting rainwater is a great way to use sustainably sourced water. The new water storage tank was connected to an existing tank installation using 25mm full bore pipe and fittings and a 1" ball valve at the outlet of the tank.

Thanks for showing the reality, what we all go through with DIY, Some posts make it look so easy till we try. Love the humor😂

Hi Bridget, it’s a pleasure… haha, yeah, unless you doing it all the time, it can look easy watching a video but some things can be a little tricky when you actually do it for the first time. Thanks for the comment 😊

[@DorisL-ti6yn]

This was super helpful ☺️. Thanks.

[@GrantBurton]

It's a pleasure. There are two longer videos (about 50 minutes each) where I explain our setup and installation. In those videos, you'll see the 0.6kw pump.

[@justdoingstuffrsa751]

You should install a first flush system. It keeps out all the sand from the gutters and roof.

Hi, thanks for the tip… I also have a video on how to build and install a basic first flush system here if you are interested th-cam.com/video/_AQ2Wd8F_h8/w-d-xo.html

This was very funny!

Nice one

[@GrantBurton]

Thanks 😊

Hey Grant, please explain how the submersible pump works. Do you just switch it on manually when its full? Does it have run dry protection? Is there a way to automate the pump so that it turns on when its full? I am from South Africa so any information about where you get this equipment would be appreciated.

[@GrantBurton]

Hi Bryan, on our setup, when the tank is full or if we need to transfer water to the main tanks, I manually turn on the pump and let it run. The submersible pump has a float switch built in so it will turn off automatically when the water level drops to the bottom of the pump, where the water pickup is (a form of run dry protection i suppose... so long as the pump is upright). Currently the pump is hanging about 150mm from the bottom of the tank so it will turn off before the tank empties completely. It also limits the potential for the pump to suck up sediment that may collect at the bottom of the tank.
I'm sure there are float switched that one could install to automatically turn on the pump once the tank reaches the level of the installed switch... have never used one so not exactly sure of which type to use. Guessing it would need to be some sort of normally open type float switch that is tethered mid way up the tank... so the the float switch floats on top of the water and rises as the water level rises... then as the water level reaches the top of the tank, the float switch is tilted upright (because it's tethered midway up the tank) and will turn on, thus starting the pump and transferring water. As the water level drops to below the tethered point, the float switch will eventually hang / tilt down again and turn off. I'm not sure if this is the best method to achieve auto pumping when full.... just a guess.
All the equipment, pumps, fittings, valves, switches, etc. should be available in most cities at the local irrigation / farm stores. I normally call in at TURFAG or sometimes Spilhause or PE Plastics here in Port Elizabeth. Not sure what stores are around your area though. Could also try The Co-op.
If you find out anymore, please let us know.
