Gilleland Creek Watershed: Retrofitting Stormwater Detention Basins
Two stormwater detention basins in the Gilleland Creek watershed will be monitored in this study. The Pon Court Basin has been retrofitted with a programmable automated valve. This device will allow the runoff from the watershed to remain in the basin for designated amounts of time before being discharged to the creek. The Copperhead Basin, with a traditional detention system, will be used as a control site for comparison. Both basins are equipped with automated monitoring equipment to evaluate the bacteria concentrations in inflow and outflow.
We expect the longer holding period, allowing time for sedimentation and exposure to sunlight, will reduce bacteria concentrations in outflow at the Pon Court Basin.
