Glades Road Water Treatment Plant Chemical System Improvements

The Glades Road Water Treatment Plant Chemical System Improvements project for the City of Boca Raton consisted of the replacement of the two existing 6,000-gallon sodium hydroxide bulk storage tanks; demolition, removal and disposal of the existing 11,000-gallong steel acid tank and associated piping, ladder, platform and accessories; removal of the existing chemical-resistant coatings of the concrete secondary containment structures, re-sloping of the floors of the containment structures to the pump sumps, and re-coating of the structures (acid, color polymer, antiscalant, and sodium hydroxide storage areas); re-coating of the polymer tank; pressure washing of the chemical bulk storage tank area canopy; replacement of all existing sump pumps in the containment structures; installation of a drain to accept eh sump pump discharges from the containment areas; replacement of Teflon-lined steel tank fill, overflow, and vent piping for the polymer and sodium hydroxide bulk storage tanks with Schedule 80 CPVC piping; installation of a 3-way valve in the sodium hydroxide metering pump return piping to allow the pressure relief valve blow-off to be directed to either tank with the other tank isolated; relocation of the antiscalant tank fill port to be inside the secondary containment structure, removal of the metering pump supply and return piping, and capping of the metering pump supply and return connections to the tanks; re-installation of existing electronic tank level sensors on the new sodium hydroxide tanks; removal of the visual level indicator on polymer tank; replacement of the existing five (5) sodium hydroxide metering pumps and piping; relocation of chemical metering pump control panels and e-stop buttons; replacement of all existing magnetic flow meters; re-painting and re-coating of the floors, walls and ceiling in the equipment and electrical rooms and the sodium hydroxide, acid, and anti-scalant/color polymer metering pump rooms; installation of chemical splash shields in the new sodium hydroxide pump room; replacement of four (4) existing emergency shower/eyewash stations; replacement of four (4) metering pump room fiberglass vents; relocation of existing control panel and power switch for electric actuators on sodium hydroxide metering pump supply piping to outside of pump containment area; and installation of a flow switch on the drain line to the containment area for sodium hydroxide.
