Orange Street Reservoir Project
Located near downtown and serving the north grid of the JEA water system, the Main St WTP currently receives water flows from seven active well fields. Two below ground concrete reservoirs serve as the plant’s storage tanks: the 1.0 million gallon (MG) First St Reservoir and the 3.0 MG Orange St Reservoir.
When the Main St WTP is fully functional, groundwater from the Floridan Aquifer is pumped into the Orange Street Reservoir. From here, water flows by gravity to the First St Reservoir, then pumped to both the north and south grids via the WTP pump station. Sodium hypochlorite is injected into the water for disinfection and maintenance of a chlorine residual prior to distribution.
The reservoirs were inspected in 2005 and were found to be deteriorated and damaged in spots. The report recommended rehabilitation or replacement of both reservoirs.
The resulting rehabilitation/replacement project was divided into two phases: 1) Phase I – rehabilitation of the First St Reservoir and upgrade of the pump station; and 2) Phase II – replacement of Orange St Reservoir.
Phase I rehabilitation of the WTP was completed in June of 2009 and included the replacement of the high service pumps, the replacement of the sodium hypochlorite disinfection system, modifications of yard piping and the rehabilitation of the First Street Reservoir. The second phase of upgrades, the subject of this Project Definition, includes the replacement of the Orange Street Reservoir and installation of an ozone/tray aeration system for odor control.
The project is scheduled to be complete in Spring 2013.
