RECOMMENDED ACTION:
Adopt Resolution No. 1432 approving plans and specifications and authorization to advertise for
bids for the "D1" and "D2" Steel Water Tanks Interior and Exterior Coating and Miscellaneous
Repairs, Project No. 5024.
ITEM EXPLANATION:
The "D1" and "D2" tanks are located along Black Rail Road just south of Poinsettia Lane, as shown on
Exhibit 1 Location Map. The "D1" and "D2" tanks are both 75 feet in diameter and 40 feet in height
with a cone roof and a capacity of 1.25 million gallons each. The D1 tank was constructed in 1958 and
D2 tank was constructed in 1969. The exterior of both tanks were last overcoated in 1995 and the
interior of both tanks were last recoated in 1998.
As part of the reservoir repair and maintenance program, this project involves the following
improvements:
• The exterior shell coating of both tanks is heavily chalked and exhibits minor localized spot
corrosion from mechanical damage, which will be repaired by applying an over-coating
consisting of a zinc / hydrophobic acrylic / HDP acrylic paint.
• The interior coating system of both tanks is comprised of an epoxy coating that is in poor to
fair condition on the roof and fair to good condition on the walls and floor. The appearance of
corrosion is emphasized by the formation of rust bleed staining. The existing interior coating of
both tanks will be removed and replaced with a zinc / polyamidoamine epoxy coating.
• The severely corroded steel overflow pipe on D1 tank will be replaced.
• On both tanks, to comply with Occupational Safety & Health Administration (OSHA)
requirements, a new exterior steel ladder with safety cage plus handrailing mounted offset
from the roof hatchway will be installed, plus a 30-inch diameter manway will be added on the
tank wall for access.
• On both tanks, to comply with California Department of Public Health requirements, the roof
vent screens will be replaced to prevent contamination from birds, bats and insects, and a %"
sample tap will be installed on each tank.
• On both tanks the severely corroded earthquake rods that are attached to the roof beams will
be replaced, the caulking and backer rod at the tank / concrete ringwall interface will be
replaced, the liquid level indicator board will be replaced, and minor spot repairs will be
performed.

for this inspection work will be prepared with a budget established at $50,000 to cover the amount of
hours estimated based on the proposals.
