 Wood Products Manufacturing Facility
Problem:
A manufacturer of wooden structural components has an onsite stormwater management facility that incorporates a series of catch basins flowing into a single hydrodynamic separator, then into a retention-infiltration pond. Since they retain all stormwater onsite, they are not required by law to have a stormwater discharge permit.
Their facility experiences heavy truck and forklift traffic plus their manufacturing processes yield ever present wood debris and sawdust. These operating conditions fouled their stormwater treatment system with a layer of organic sediment that prevented the retention pond from infiltrating at the rate needed to handle their stormwater volume. The hydrodynamic separator was not able to remove the wood particles so each year, they had to undertake the difficult and costly project of excavating the bottom of the pond and replacing a 6 inch layer of filter rock.
Solution:
Once they installed CleanWay® Storm Clean® filtration inserts into the catch basins at their facility, sediment no longer accumulated in the infiltration pond, so it stays clean. Their system is now operating in its third year with no decrease in efficiency. |
