Performance KPIs for Baseline and Planning Scenario
3.4 MODULE WATER
Overall, the Planning Scenario performed significantly better than the Baseline.
The stormwater service level increases by 79% as the initial baseline conducted all
stormwater into the municipal system. The 30cm depth swales provide a detention
volume of 146 cubic meters, reducing the peak run-off coefficient by 0.1 (from 0.8
to 0.7) due to the increase in green space overall. The natural water balance subseqeuntly
also improves as the run-off potential is decreased, infiltration icnreased,
and evaporation as well enhanced. The potential for stormwater quality improvement,
or treatment of TSS, nutrients and heavy metals, increases as well with the
addition primarily of ground-level stormwater BMPs (best management practices).
With the addition of underground storage, potable water that could be saved calculated
over a period of a year based upon rainfall data given for Vienna is 437 cubic
meters. This water could be used for irrigation, toilet flushing or other uses, to be
determined at a future date.
