The East Bay Municipal Utility District (Oakland, CA) awarded a contract of $6,183,310 to Abhe & Svoboda, Inc. of Prior Lake, MN, to perform lead abatement and coatings application on the Mokelumne Aqueducts.
The project involves abrasive blast-cleaning and recoating a total of 17,815 linear feet of exterior surfaces on four sections of the aqueduct, a system of three large-diameter steel pipelines that transport water about 90 miles from the Sierra foothills to treatment facilities and raw water reservoirs.

The project addresses sections of the Aqueducts at Indian Slough in Contra Costa County and Trapper Slough, Holt Bend, and Black Slough in San Joaquin County. This work is part of a periodic maintenance program to safeguard the structural integrity of these vital water transmission pipelines.
Scope of Work
The project includes recoating 6,236 linear feet of 65-inch-diameter piping, 5,581 linear feet of 69-inch-diameter piping, and 5,998 linear feet of 89.5-inch-diameter piping (17,815 linear feet total). Pipe supports, appurtenances and related work are required, and the project runs over land and water.
SSPC-QP 1 and QP 2 certification are required. The existing coatings contain lead; Class 1A containment (SSPC-Guide 6) is required.
