The City of Lodiís Wastewater Treatment Facility is staffed by state certified wastewater operators. A Compliance Maintenance Report is filed annually with the Wisconsin Department of Natural Resources and the facility has consistently received Grade A reports. Recently the State of Wisconsin adopted stringent phosphorus requirements for treatment plants and our facility was chosen to work closely with the Department of Natural Resources as a pilot project for these new reduction requirements.

Monthly Service Charge $14.64 
Volume Charge - per 1,000 gallons $9.40


Phosphorus Compliance

The Wastewater Treatment Facility has a design flow of 546,000 gal/day and treats 310,000 gal/day (2013) while meeting the 1 mg/l phosphorus limit. On November 1, 2011, the City of Lodi's WPDES Permit was reissued with a compliance limit of 0.075 mg/l (annual avg) and 0.22 mg/l (monthly avg) total phosphorus by September 30, 2020. The City would have to construct upgrades at the wasterwater treatment facility to meet the new water quality based effluent limit (WQBEL). The Wisconsin DNR also allows alternative, watershed-based compliance options in lieu of treatment facility upgrades. The two alternatives are Adaptive Management and Water Quality Trading. In November of 2012, the City submitted an Operation and Needs Review (ONR) to the DNR indicating the costs of Adaptive Management were less than the cost of upgrading the treatment facility.

Upon completion of the ONR, compliance with the future WQBEL by upgrading the treatment facility still remained a far more costly option than pursuing Adaptive Management. In October of 2014, the City submitted a Watershed Adaptive Management Request to the DNR. 2016 Adaptive Management Plan
