The proposed project would involve the replacement of a raw-water pipeline segment aligned under the San Lorenzo River in the city of Santa Cruz. Construction of the segment would use microtunneling to drill an approximately 225-foot west-to-east tunnel under the river within which the replacement 24-inch-diameter pipeline would be installed. This new pipeline would be connected to the existing raw water conveyance system on the east and west banks of the river, each side connected via approximately 150 feet of pipe using open trenching. The existing 20-inch-diameter steel pipeline segment would be capped and abandoned in place.
