System: Pasco

Description:  The existing grit system at the Seven Springs WWTP is at the end of its useful life and is failing.  Halff Associates completed a technical study in 2021 to evaluate various technologies to replace the existing grit removal and handling system.  The study determined the most appropriate grit removal technology for the Seven Springs WWTP application is the Smith and Loveless Pista VIO equipment.  Design of the new grit removal and handling system is currently underway.  Construction of the new grit facility is anticipated to commence later this year.
