how to build a stormwater pit (a rough guide)

Step 1:
Dig a really, really big hole and put in pipes.


Step 2:
Build custom formwork for concrete pit.


Step 3:
Pour concrete.


Step 4:
Remove formwork and reset for next pit.

Step5:
Place grate on top and backfill trenches.



On a slightly more detailed (and serious) note, most steps took over a day to complete - there's about 7 days labour in each pit and we have 3 to pour!

We employed a plumber to dig and shape the trenches, lay the pipes and connect to the stormwater main - he did an amazing job considering all of the hurdles.

As the pits themselves were incredibly over-engineered (council specs), it became difficult to find someone to take on the project and actually get them in the ground (both the plumber and concreter refused).

We owe everything to my Dad who gave up countless days to design the formwork, piece it together and manage the process - including negotiate all sorts of setbacks like tight spaces and council inspectors (sometimes wishing the council inspectors would fall in the tight spaces).

Thanks Dad.
