Document Description
NOTE: Review Per Lead The applicant, Pasadena Water and Power, filed a Conditional Use Permit application to allow the construction, installation, and operation of an ion exchange, (IX) treatnebt system, a booster pump station, a chloramination system, and piping at the City's Sunset Reservoir site. The system will require up to two pairs of IX vessels up to 12 feet in diameter and 17 feet tall. The booster pump station enclosure will be approximately 13 feet tall and 440sf in size (20- feet by 22 feet). The chloramination system consists of two above-ground, tanks that would be installed under a canopy-type structure to protect them from direct sunlight. The area of canopy is 476sf (28 feet by 17 feet). The 6,650-gallon sodium hypochorite tank and 1,800 gallon ammonium hydroxide tank would be approximately 11 feet in diameter and 15 feet in height, and six feet in diameter and ten feet in height, respectively. The existing 1,207sf maintenance building and chlorine building would be demolished as part of site preparation for the project.
