PROJECT UPDATES I WATERQUALITY 13 <br />MCCARRON'S <br />WATER TREATMENT <br />PLANT UPDATE <br />Water quality <br />at McCarron's <br />Water Treatment <br />Plant is already <br />excellent and the <br />addition of the new <br />ozonation process <br />will improve water <br />quality even further. <br />The water utility is currently <br />in the midst of major im- <br />provements to the McCar- <br />ron's Water Treatment Plant. <br />The facility serves all SPR- <br />WS customers and provides <br />water to 452,000 people. <br />The construction process <br />for the new facilities is <br />now 20 percent complete. <br />Demolition of unnecessary <br />infrastructure and extensive <br />excavation have cleared <br />the way for new construc- <br />tion, much of which will be <br />subterranean. In the fall of <br />2022, work began to pour <br />the foundations of the new <br />facilities and to install the <br />pipework that will carry water <br />to the new treatment plant. <br />Work will continue through <br />all seasons and is expected to <br />culminate in late 2026. <br />Thus far, work has proceeded <br />on time and on budget. The <br />project team includes talented <br />staffers from both SPRWS and <br />the design -builder who bring <br />decades of experience to the <br />effort and are committed to a <br />positive outcome. <br />Upgrades to the facility include <br />new softening, clarification, <br />and re -carbonation processes. <br />Each of these processes are <br />already utilized by the facility. <br />Wth the infrastructure used <br />in these processes currently <br />nearing 100 years in age, <br />they are becoming a reliability <br />concern. <br />Anew treatment process, <br />ozonation, will be added to the <br />facility as well. Water quality in <br />the existing facility is already <br />excellent, and ozonation will <br />improve water quality even <br />further. <br />The proposed treatment <br />process was tested on a small <br />scale for a full year prior to the <br />start of construction to confirm <br />that water quality from the new <br />facility would remain excellent. <br />Upon completion of the new <br />facilities, extensive testing <br />will be performed to ensure <br />that the new facilities work as <br />planned. <br />This new infrastructure is <br />expected to serve St. Paul <br />metro area residents for many <br />decades to come. <br />Page 41 of 76 <br />
