Responsibilities

The Wastewater Treatment Division is responsible for the operation and maintenance of two wastewater treatment facilities. Combined, the facilities process an average of 4.3 million gallons of water per day or 1.6 billion gallons annually. This produces an effluent that not only meets, but also often out performs the National Pollution Discharge Elimination Systems (NPDES) permit requirements.

Other functions of the Division include laboratory analysis of samples required for NPDES reporting, plant process control, industrial monitoring, and potable water analysis.

Pretreatment

The City's Pretreatment Coordinator is responsible for the enforcement of the Sewer Use Ordinance and the United States Environmental Protection Agency approved pretreatment program.

Industrial users in the City with process waste streams are permitted and monitored to assure pollutants are not discharged to the wastewater system. 

Routine Inspection of Lift Stations

Routine inspections are conducted at each of the 26 sanitary sewer lift stations and 3 storm sewer lift stations to ensure their proper operation and maintenance. A comprehensive review of each operating system is conducted to assure uninterrupted operation. 

Upgrade of Lift Stations

As part of the minor capital improvement process, lift stations are renovated and updated prior to the equipment reaching the end of its service life. Updated technology is installed to maximize efficiency and prevent system failures.
