Cerro Gordo, Il.    2008

Cerro Gordo's filter wasn't getting the desired flow, so we did some brain storming & came up with a new game plan. This time we used a mini excavator to stir the rock while pumping water out of the out-fall area. This process was very effective, because as we discovered algae & sludge had built up in the 1st 3 to 4ft of both outside edges of the filter. By digging up the rock it stirred up that algae & sludge & allowed it to move to the outflow where we pumped it to the secondary cell.

The rock in this filter is only 1.5 in. where as most rock filters would normally have at least 3x5 in. or 5x7 in. rock.
