3. From the distribution box, runoff influent flows into a network of pipes and is distributed into each stormwater treatment.
4. Runoff influent moves through the stormwater treatments.
5. Runoff leaving the treatments (effluent) is conveyed by perforated subdrains into a sampling gallery.
6. In the sampling gallery, the effluent is monitored in real time for the following characteristics: flow, pH, conductivity, dissolved oxygen, temperature, and turbidity. Also in the gallery, automated samplers collect samples of runoff at discrete time intervals over the rainfall hydrograph. These samples are evaluated for the same range of contaminants to generate performance characterizations.
