Sewer service bills are billed quarterly to all residential and commercial properties. 1st Quarter bills are mailed out early May, 2nd Quarter early August, 3rd Quarter late October and 4th Quarter mailed early February. The due dates are at least 22 days after the billing date. There is a 4.5% penalty per quarter on an unpaid balance for bills not paid by the due date.

Any delinquent balance after the 3rd quarter due date is placed on the homeowner's tax bill, with an additional 10% penalty.

Sewer Service Bill Charges

The wastewater of the City is collected and treated by the wastewater system operated by the Milwaukee Metropolitan Sewerage District (MMSD). The sewer bill is composed of 4 charges:

The MMSD Connection Charge

This covers the sewerage treatment costs. The 2016 rate is $5.78 per connection. It is billed by the City of Greenfield on behalf of MMSD.

The MMSD Consumption Charge

The MMSD consumption charge is based on Milwaukee Water Works meter reads and billed on behalf of MMSD. The 2016 rate is $ 1.98 per thousand gallons. The 1st quarter reflects the meter reads taken from mid October to mid January (winter quarter). Residential customers (1-4 family units) are billed on this actual consumption read for the 1st Quarter sewer bill. The next three quarters are billed on this consumption (dependent on consistency). Commercial customers are charged for actual water usage reported on all 4 quarters. The minimum charge on consumption is $ 6.00.

The Local Sewer Charge

This is billed to recover the costs of maintaining the sanitary sewer system. This fee for 2016 is $22.65 per unit. A single family home is described as one unit. A duplex would be a two unit dwelling and an apartment building with 8 apartments would be an 8 unit dwelling. This charge is computed by dividing the revenue shown on the Greenfield Sewer Service fund budget by the total number of units in the City.

The Storm Water Charge

This charge was established in August of 2009 in order to meet new state requirements to manage storm water quality and quantity on all impervious surfaces. The average impervious surface per single residential unit is 3,630 square feet, or 1 ERU (equivalent runoff unit). Per a revised resolution passed by council on 11/17/15, the current quarterly charge is $ 15.00 per ERU. Duplexes are based on 1.1 ERU and any business or residential dwelling 3 units or larger are based upon actual square footage of impervious surface to determine the ERU.
