The project consists primarily of converting the City’s existing chlorine gas and fluoride chemical injection systems to on-site chlorine generation and fluoride saturation systems for Wells 4, 7 and 13. This includes providing all equipment necessary for the conversion. The existing chlorine and fluoride system housings will be demolished and replaced with new masonry buildings, constructed in their existing footprints with extensions as needed to accommodate the new systems near Wells 7 and 13. Well 4 scope consists of installing new chemical injection piping to deliver chlorine and fluoride from chemical systems at Well 13. To ensure proper drainage of the chemical systems in the event of a spill or cleaning, a chemical wastewater system including sump pumps and drainage piping is to be installed. The contractor shall install mixing pumps on the discharge lines of Wells 7 and 13 to provide proper blending of chlorine and fluoride chemicals into the water. This project also requires the removal and patching of large areas of asphalt to accommodate installation of chemical and waste piping. The contractor shall include paving of affected road sections within the site, as indicated in the drawings.
