multifamily is residential or non residential for water billing ?

[Lak Chilam]

Hi,

My property is in Atlanta. we have a water main meter(8in) and getting 9000$ permonth for 64units property. I know which is very high, my property is listed as non residential as per water company since meter is 8in, currently I am paying as a landlord full monthly water bill and all my profits this bill is eating.

I ask the water company my property has submeters if i make those active is the water bill going to reduce by making the property as residential? they mentioned that still one main meter which is 8in so its not going to reduce, i mean each tenant gets 140$ monthly which is ridiculous. any suggestion to reduce the water bill ? or even if I charge back to tenants i don't want they feel burden such a high price.

Thanks, Lak
