AGENDA ITEM: Rehabilitation of Ground Storage Tanks at Water Plant Nos. 1 and 2
Bid No. 0203-1
SUBMITTED BY: Donna Kaluzniak, CEP, Utility Director
DATE: November 19, 2002
BACKGROUND: After completing an inspection of the ground storage tanks at Water Plant
Nos. 1 (469 l lt~ Street) and 2 (2301 Mayport Road), our tank consultant, HGTI, recommended
rehabilitation and coating of the tank interiors be completed as soon as possible. There are two
200,000-gallon concrete tanks with aeration and baffiing at Water Plant No. 1, and one 500,000-
gallon tank at Water Plant No. 2.
A DEP inspection later in the year resulted in a concern over the level of hydrogen sulfide in the
tanks, and a recommendation from DEP that the City analyze the effectiveness of the aeration.
Although hydrogen sulfide levels have not changed since the plants were placed on line, as an
additive alternate, staff included the addition of up to 28 ventilators on the three tanks. This will
improve hydrogen sulfide removal from the tanks, which will also extend the life of the tank
coatings and structure.
The vents specified were from Crom Corporation, however, all, vendors were advised that
substitutions could be requested and would be reviewed for approval by HGTI. One vendor,
Clifton's Tower Service, Inc., requested a substitution using their custom vents, which was
approved by HGTI.
