Ann Arbor Raises Water, Sewer Rates

At its June 20, 2011 meeting, the Ann Arbor city council gave final approval to increases in water, sewer and stormwater rates.

In terms of revenue generated to the city, the rate increases are expected to generate 3.36% more for drinking water ($664,993), 4% more for the sanitary sewer ($829,481), and 3.35% more for stormwater ($176,915). [.pdf of complete utility rate changes as proposed]

According to the city, the rate increases are needed to maintain debt service coverage and to maintain funding for required capital improvements.

The city’s drinking water charges are based on a “unit” of 100 cubic feet – 748 gallons. Charges for residential customers are divided into tiers, based on usage. For example, the first seven units of water for residential customers have been charged at a rate of $1.23 per unit. The new residential rate for the first seven units is $1.27.

The city’s stormwater rates are based on the amount of impervious area on a parcel and are billed quarterly. For example, the lowest tier – for impervious area less than 2,187 square feet – has been $12.84 per quarter. Under the new rate structure, that increases to $13.24.
