The Sewer Utility provides for the collection of all wastewater and industrial waste discharged into our system. Your sewer usage charges are based off of your water usage. For example, if you use 3,000 gallons of water in a month, you will be charged for 3,000 gallons of sewer.
Sprinkler Meters
For those who water their garden a lot, it may be beneficial to have an additional meter rental charge. These are typically known as sprinkler meters and once installed, any water going through this meter will not receive any sewer charges. Click here to view the rates.
Lawn Permits
Those who are looking to buy and install a new yard may be qualified for our lawn permit. With this permit, you can choose three consecutive months in which you will be billed for your average sewer usage. Any usage that goes over this average sewer usage while watering the new lawn will not be subject to sewer charges. This form can be found under the top ribbon, "Forms & Permits".
Bulk Water
The Wastewater Treatment Facility offers a bulk water service where companies can fill up their tanks or trucks with water. Anyone looking to use this service can contact the Utilities Superintendent, Greg Moser, at gmoser@vi.slinger.wi.gov. For additional information on the rates, click here.
WASTEWATER TREATMENT FACILITY
The Slinger Wastewater Treatment Facility was expanded in 2008-2009 to treat an average of 1.5 million gallons of sewage a day. This expansion was designed to accommodate Slinger's future residential, commercial, and industrial growth for the next 20 years.
The facility utilizes biological, chemical, and physical treatment to meet and exceed Wisconsin Department of Natural Resources effluent limits. Initial processes remove the larger, inorganic materials, followed by a biological system which is designed to duplicate and optimize nature's own naturally occurring treatment processes. At the end of the treatment process, the wastewater is passed through a state-of-the-art disinfection system prior to discharging into the Rubicon River. Biological solids generated during the treatment process are treated and recycled back into the environment.
WASTEWATER TREATMENT PROCESS
Wastewater from homes and commercial buildings enter the treatment plant via a 30 inch and a 24 inch pipe nearly 18 feet and 25 feet below the ground respectively. Large debris is removed from the wastewater in the first treatment stop by an automatic bar screen. Small, heavy solids such as sand and coffee grounds are settled and removed in a grit chamber following the bar screens.
The wastewater is then pumped to a large tank called an oxidation ditch, where micro organisms are given the right conditions to treat the waste. Some of these conditions include the right amount of time, oxygen, pH levels, and micro organism populations adequate to treat the waste. The water remains in this tank for approximately 24 hours before the flow is divided and sent to two other tanks called clarifiers.
Clarifiers are the tanks where treated waste settles to the bottom where it is either sent to a storage tank to await disposal or sent back to the oxidation ditch to provide the right population of micro organisms to treat the incoming waste. Clear water rises to the top of the clarifiers and goes over a weir before it travels to a disinfection building.
Once at the disinfection building, water travels through a channel where it is exposed to ultra violet (UV) lamps. This UV exposure mutates the cell walls of any pathogenic organisms, essentially destroying them. After the water has been treated by the UV system, it goes down a series of aeration steps before entering a tributary of the Rubicon River.
