The inlet device shown here will regulate water flow and sediment entering the Rainstore3 chamber.
An overview shot of the project. Notice that the Rainstore3 cells had been shipped four units high and reassembled into eight unit high cells on site. The paper separated the four unit high cells. When assembling cells, adequate care must be taken to ensure all 36 cylinders completely connect to the adjacent cell’s cylinders.
A completed view of the sight. Notice the maintenance port to the left of center of the photo.
