Our water harvesting tanks are well on their way to completion (see my original post)!  Over the last couple weeks they poured the oversized slabs (taking 16 yards of concrete each) and have started to erect the two 18,000 gallon tanks.  The tanks are held together by some 1,200 bolts.

The tanks are built from the top down.  Here a lift holds up the tank for the final assembly.

Bolts, lots and lots of bolts - over 1,200 per tank.

When this project is complete it will be one of the largest rainwater harvesting systems in the United States….and my Hydrology professors never thought I would use my degree, jeesh.

  1. When rainwater harvesters were first introduced to the UK, all suppliers stressed the point that the tanks had to be emptied and cleaned ot every 5 to 7 years to remove the sludge build up from the bottom of the tank.
    Nothing has changed in that the filters remain the same, but the suppliers no longer ‘mention’ this very important aspect of the maintenance if you want to keep the water sweet.

  2. Thanks for the comment! We have built this system to accomodate for about a 6″ buildup before we have to clean them. Unfortunately, being in the desert, there is quite a bit of dust that gathers on the roof so it will be interesting to see how long it takes for the debris to accumulate.
