Visit the GIS Infrastructure Map to see where city infrastructure projects are happening.
The City of Stillwater and Stillwater Utilities Authority is making improvements to multiple facilities at the Wastewater Treatment Plant. These include: a new lid for Digester A, an automatic transfer switch, a gas collection system used for fueling the heat generation system, basin drains, fencing and roofing.
Sludge digestion produces corrosive gases that have led to the deterioration of Digester A and B lids.
