The public event happened Wednesday afternoon at the plant site off of Skyliners Road.
The new plant will help the city meet the federal government's requirement that water be treated to prevent such parasites as cryptosporidium.
City Councilor Victor Chudowsky says it will make our good water system better.
"But the plus side is once the filtration system is in place, we will be able to better use our water and increase the quality of it. And we'll have accesss to it the entire year. Right now we turn it off to prevent turbidity. So it will be a big turn around in the water supply and on the dependability of the supply."
The plant should be completed by July of 2015 and operating by December of 2015.
