Rainwater tank - backfilling and first collection!

Thursday, June 11: The beginning of another day of major transformation. Before.





Ferrying more gravel down the site...





The overflow pipe in place.



Once sufficiently covered in pea stone, the cistern is completely swaddled.





The inflow pipes are put in place.











It was raining as we hooked up the pipes... which meant the instant gratification of getting water in the cistern right away!
(this inflow setup was obviously temporary).
On the right, you can see the trickle of water coming from the filter overflow.



The gravel over and around the cistern is complete.



.. the final grading, at last. 2" of rigid insulation (4' wide) went in over the length of the inflow pipe - you can just see it peeking out at the far left.




Big thanks to our project sponsors:

Unit Precast for donating their labour (co-ordinating and installating the pump system)

ZCL for donating the massive fibreglass tank!

...

and to our excavators and earthmovers, Alltask Property Improvement.

Nice set up of the underground rainwater tank. This will be sustainable in right form and settings.
