On June 7, Wharton-Smith joined St. Johns County representatives as they hosted a ribbon-cutting ceremony for the newly upgraded Hastings Wastewater Treatment Plant.
The facility underwent $6.76 million in improvements, funded by disaster recovery funds allocated to St. Johns County in response to damages caused by Hurricane Matthew. These improvements involved replacing and upgrading assets at the plant to enhance its capacity to handle peak flows during storm events. Additionally, critical equipment was raised above the flood elevation, and measures were taken to improve reliability and redundancy for maintenance and emergency response activities.
“We have not only elevated the tanks and critical equipment above flood elevations – but we have raised hope in the Hastings community that they are important, and St. Johns County is meeting their needs for safe wastewater services,” District 3 Commissioner Roy Alaimo said.
Congratulations to the project team!
About the Project
The Hastings Wastewater Treatment Plant improvements included site work and civil improvements to enhance vehicular travel within the facility. Surge tanks were upgraded to improve their functionality. A new biological nutrient removal (B.N.R.) tank was installed, featuring two trains that utilized the 4-Stage Bardenpho process with internal recycle pumps, blowers, mixers, diffusers, and a post-aeration aerator.
The existing micro-C glycerin and proposed alum feeds were rerouted from the chemical storage building to the B.N.R. tanks to facilitate carbon addition and phosphorous removal. Mechanisms in the secondary clarifiers were upgraded to enhance their performance. A new RAS/WAS pump station and piping, valves, and appurtenances were also installed. Implementing a new tertiary filtration system further improved the plant’s treatment capabilities.
The upgrades included all-new electrical wiring throughout the facility, ensuring a reliable and efficient power supply. Moreover, a standby generator was installed to provide backup power when needed. The project also involved the installation of new controls for both the existing and proposed equipment, enabling effective monitoring and operation of the wastewater treatment processes.
