This is one of the first wastewater plants in Missouri utilizing Design-Build delivery, and the first Design-Build in Missouri to utilize State Revolving Funds (SRF). SRF financing will save the City over $40 million in interest when compared with conventional financing. This project paves the way for municipalities throughout Missouri to maximize their dollars utilizing the cost and schedule saving efficiencies of Design-Build with low-interest SRF financing.
The City of Liberty had outsourced treatment to a neighboring community for decades. Facing near-term rate increases, uncertain future rates and potential treatment capacity issues, Liberty began studying alternatives, and decided the City would build their own facilities and discontinue outsourcing of treatment.With this information, in August 2013 the Citizens of Liberty voted overwhelmingly 91% in favor of the project.
To maintain user rates, the new facilities had to be completed and operational by first quarter 2017. In August 2014, the Goodwin team was selected. Construction of the new 7 MGD plant, two 10 MGD pump stations, 18,000 feet of force main, 6,000 feet of collector roadway, administration and maintenance facilities were completed by December 2016. Treatment operations began on January 3, 2017.
Based on the cost and schedule savings gained through the Design-Build process, additional scope was added, including over 6,000 feet of trunk sewer. This work was completed in March 2017 with completion and close out scheduled for May 2017. This project is a perfect example of a City looking out for the best interest of its citizens’ hard-earned dollars. Rather than continuing the status quo, Liberty pursued different treatment options and innovative delivery.
