WATER STORAGE REPAIRS

GUSTAVUS, ALASKA

April 1, 2025

Introduction: The work under this contract consists of repairing leaks and installing cathodic protection on 2 potable water tanks and appurtenances for the National Park Service (NPS) water facilities located at Bartlett Cove. These tanks exhibit signs of leakage at bolted lap seams and are experiencing early signs of coating degradation and metal loss in submerged areas. This project will implement manufacturer-recommended repairs to leaking lap seams and install a sacrificial cathodic protection system to extend the tank’s service life and preserve water quality. Glacier Bays Bartlett Cove is located next to the gateway community of Gustavus an off-highway city in Southeast Alaska.

The contractor is required to supply all materials, parts, tools, equipment and labor necessary to complete the stated work. All work will be performed under a single contract.

Description of site: The NPS tank facilities at Glacier Bay include:

Two bolted steel, glass-fused-to-steel type constructed potable water tanks with the following attributes:

Both tanks are open to the atmosphere and co-located at the same elevation at the top of a small hill. They are at the highest elevation point in the water system.

Both tanks stand approximately 29 feet in height and have an approximate diameter of 25 feet. The older tank was constructed in 1991 and was manufactured by Aquastore Tank Systems. It has a 108,000 gallon capacity according to its manufacturers design plate on the tank. The newer tank was constructed in 2001 and was manufactured by Fusion Tank. It has an estimated volume of 109,000 gallons.

Both tanks can be individually isolated off-line as necessary during cleaning work.

Both water tanks have roof man-way hatches 24 inches inside-diameter.

Both tanks have perimeter man-way ladders with locked safety cages starting at approximately 6 feet above ground level.
