Summary:
Four projects at Water Treatment Plant 2 began construction in December 2018. The work includes a building with new lime feed equipment; basin improvements including new equipment at Basins 2 and 4, and repairs and rehabilitation at Basin 3; a new chlorine dioxide disinfection process; and replacement of the steel clearwell with a new concrete clearwell. Collectively, these projects will renew aging infrastructure, ensure water quality and regulatory compliance, enhance staff safety, and promote reliable operation.
Lime Feed Building. The precast concrete building is complete, and the new lime feed equipment is currently being installed. In September 2019, the new lime silos arrived on-site and were set in place atop the building. The project is anticipated to be completed in Spring 2020.
Basin Modifications. Work at Basin 3, including metal repairs and new paint coatings, was completed in Spring 2019. Basin 2 was taken out of service in September 2019; the new equipment has been installed and will be ready for service in February 2020. Basin 4 will begin construction following the completion of Basin 2.
Alternative Disinfection. The new concrete disinfection basin is complete and untreated water from the well field is now flowing through it to the treatment basins. The chemical feed building has been constructed and is ready for interior equipment and piping. The project is anticipated to be completed in Spring 2020.
Above-Ground Clearwell. The new clearwell has been constructed and was put into service in June 2019.
This presentation will provide information on the construction progress of these Water Treatment Plant 2 projects.
