Water bills for small co op buildings

I remember a while ago someone was asking about water bills for small buildings in Park Slope. I believe they were getting some sort of outrageous water bills and wanted to compare pricing.

I can't remember if they ever got the answers they wanted, I just thought of it now because we just received our quarterly water bill from the DEP and thought if they were still interested, I would share what we, a 7 unit (with only 5 occupied apartments) building in Park Slope pays for water quarterly.
