Detroit at $750 an Impervious Acre, How to Figure Out Your Monthly Water Rate

By Richard C. Clement

Debugging the new water rates in the City of Detroit takes a definition of what Impervious Surfaces are. Wikipedia defines it as:

“Impervious surfaces are areas of the earth that have been covered by any material that impedes the infiltration of water into the soil. Areas of land covered by pavement or buildings are impervious to rain water. Concrete, asphalt, rooftops and even severely compacted areas of soil are considered impervious.”

Unlocking the mystery of how much my new monthly water bill is can be solved by clicking this website link   www.detroitmi.gov/drainage  to access the City of Detroit Website article under impervious acers.  When you get there, enter your property address.  When your property is found, wait 10 seconds and double click on the picture inside the property line..  To calculate your new monthly water rate, multiply the impervious surface acre percentage times $750. The answer will equal you monthly rate.  If you are disputing the calculated amount, then you are encouraged to click here to fill out your drainage survey form and send it in to DWSD.

Eventually. a large combined sewer separation project will have to be undertaken like other cities have done in Michigan (Lansing Michigan Combined Sewer Separation Project) because of climate change in our world.

We hope this helps clear the confusion on the new rates.
