Dibble provided survey and civil engineering services to expand the existing facility to accommodate an additional 1200 inmates. The expansion covers approximately 20-acres and required new water and sewer systems as well as fire and natural gas services. The water system included storage, treatment and chlorination facilities as well as domestic water and fire suppression pumping systems. The sewer system included a sewer grinder to protect the Town of Florence sewer system. The grading and drainage design integrated the retention basins into the facility to allow use of the all components during and after storm events.

Dibble worked with the design team to expedite the design and permitting process to allow the facility to meet the State of Arizona’s deadline for accepting inmates.
