24006 Water Tower Interior Paint Repair

USDA, Ames, IA

December 12, 2023

Project Requirements:

1.0 A. Background:

In Accordance with AWWA Standards, The USDA elevated water storage tank should be cleaned and inspected every three years. The storage tank was last cleaned and inspected in 2023.

The USDA elevated water storage tank is located at 1920 North Dayton Avenue in Ames, Iowa.

It is of welded steel, double ellipsoidal construction with a 500,000-gallon capacity supported on eight columns. The elevated water storage tank was erected by the Pittsburg Des Moines Steel Company in 1958 and measures 139 feet and 7/8 inches to high water level with a 39 foot and 7/8 inches head range within the container.

In 2018, NCAH completed safety improvements that included adding non-slip ladder rung covers, installing a 24-inch diameter manway into the wet riser, and extending the 30-inch diameter sidewall manway and balcony platform. Additional improvements included upgrading the vent, extending the overflow pipe down to grade, and adding bypass piping around the tower.

In 2019 the inside and outside of the Water Tower was recoated.

In 2023 the Water Tower was inspected (USDA Inspection Report Sept 2023).

B. Scope:

1. The contractor shall provide all services and material necessary for performance of the following task:

a. Coordinate is required between USDA staff and the cleaning, inspection and painting crews for the water tower to be emptied. USDA requires 3 weeks’ notice prior to start of on-site work.

b. Complete an examination of the interior coating system in accordance with current

American Water Works Association (AWWA) M42 “Steel Water Storage Tanks”, Occupational Safety and Health Administration (OSHA) 29 CFR General Industry Standards, National Association of Corrosion Engineers (NACE) International, Steel Structures Painting Council (SSPC) and Federal and State Homeland Security requirements to identify areas that require repainting. See USDA Inspection Report Sept 2023 as a reference (estimated 471 sq. ft.).

c. Clean the vertical stand/fill piping and, the interior of the water tower. Work will include opening the grade-level drain/inspection hatch on the standpipe and removing all accumulated settled material from the vertical piping. If required, the tank interior shall be cleaned using only water and hand tools. Any tools used inside the tower shall be disinfected prior to use. A power washer may be used if needed. The services shall include the collection and legal disposal of sludge cleaned from the water tower. Note: The tank interior was recoated in 2019 and cleaned/inspected in 2023 and is not expected to require cleaning. If light cleaning is required, then care must be taken to avoid damage to the coating.

d. Prepare, prime and paint all areas that show signs of rust and/or improper adherence to internal side of Water Tower in accordance with manufacturer guidance (see USDA Inspection Report Sept 2023 as a reference (estimated 471 sq. ft.)). Prime coat shall be Tnemec Series 91-H2O Hydro-Zinc (2.5 to 3.5 dry mils). Finish coat shall be Tnemec Series 22 Epoxy (25.0 to 30.0 dry mils).

e. Upon painting completion, the Contractor shall complete an on-site inspection with the

Owner and a third-party inspector and correct any failures noted. The contractor shall complete a written report of the inspection including documentation and photographs.

Complete an evaluation of the inspection findings with regard to compliance with industry standards, safety regulations, and compliance with current AWWA Standards. The evaluation shall include a general ranking of any deficiencies identified in order of importance to the safety of the water and structure; including critical for the safety of the structure, code/standard compliance, and improvements to extend the life or reduce operating or maintenance cost. The Contractor’s and third-party inspector’s time and services to accomplish the inspection will be conducted at no additional cost to the Owner.

The Contractor shall be responsible for the coordination, hiring, and costs for the third-party inspector.

Disposal of disinfection rinsate will be coordinated with Owner and legally discharged into the site sanitary sewer.

g. Following disinfection and prior to placing the tank into service, no less than two (2) bacteriologically safe samples must be collected 24 hours apart. If either sample fails, the tank must be disinfected again, and another two (2) samples drawn as described above.

The samples shall be collected by the Contractor and sent to a testing laboratory as directed by the Owner and/or COR using containers obtained from the stated laboratory for that purpose. All costs will be paid by the Contractor. A copy of the sample results shall be provided to the COR for project documentation.

h. At the end of on-site work, the crews shall clean up all debris and material used by the crews on site and shall leave the work area in a clean, safe, and operable condition. All products shall be disposed in accordance with all Federal, State and Local codes.
