Infrastructure Improvements at Milwaukee’s Linnwood Water Treatment Plant

Water safe to consume and use during construction as filtration and disinfection processes remain in place

MILWAUKEE – Beginning in late October, the Milwaukee Water Works (MWW) will temporarily turn off its ozone system at the north side Linnwood Water Treatment Plant so infrastructure improvements may be installed at the plant. As a result, some customers who use tap water originating from the Linnwood Plant may notice a subtle difference in the taste or smell of their water.

IMPORTANT: The tap water from the Linnwood Treatment Plant is safe to drink and use during the project.

The rest of the water treatment system at the Linnwood plant will be fully operational, including chlorine disinfection, which provides effective disinfectant to meet all water quality standards and regulations. While chlorine disinfection assures adequate water quality in distribution systems, the addition of ozone has the added benefit of improving drinking water taste and smell from surface water sources such as Lake Michigan. Both ozone and chlorine disinfection will remain in use at the south side Howard Avenue Water Treatment Plant.

The Milwaukee Water Works and the City of Milwaukee Health Department (MHD) monitors drinking water quality to assure public health and safety. This includes routine review of treatment plant operational data as well as analysis of disease surveillance in the community. Existing MHD recommendations that those who are immunocompromised seek advice from their health care providers remain in effect.

“The City of Milwaukee Health Department works closely with Milwaukee Water Works to assure safe drinking water for area residents, including reviewing treatment plant operations and water samples during these types of plant improvements,” said Commissioner of Health Bevan K. Baker. “Milwaukee continues to have consistently high standards for drinking water, and has some of the safest drinking water in the nation – working together, we will keep it that way.”

MWW is installing valves upstream of the ozone process to facilitate different water flow paths through the treatment process. This will increase the flexibility in operating the plant and will add a layer of redundancy, to the benefit of all customers. Ozone must be turned off so workers can install these valves. Ozone treatment at the Linnwood Water Treatment Plant is expected to resume within 12 weeks.
