The Design Team for an urban office bldg. proposes to collect water from roof and terraces as well as mech. condensate for reuse (in irrigation and cooling tower make-up water). The project also has an area of vegetated roof. At least 90% of the average annual rainfall within the LEED boundary will be collected and stored in a sub-grade cistern. Calculations show that there is more demand for the reuse than the amount collected/stored so, theoretically, the collected stormwater will not be discharged to the sewar. Without a filter, will the veg. roof and sufficiently sized cistern be sufficient BMPs to meet the 80% TSS removal and LEED criteria (without maintenance to remove sediment from the cistern)?
