===Roof areas===
The roof areas of large commercial buildings are large impervious surfaces. Controlled roof drains have become a widely utilized tool for stormwater management with the commercial development industry. While these devices do attenuate flows, they do not significantly reduce runoff volumes. By simply directing roof runoff to a soakaway pit, you can provide a great amount of volumetric stormwater control. Consider going one step further and storing this water in a cistern for future use. Commercial rooftops are relatively clean, and complex filtration is not required for most non-potable uses.
