USIU - Miramar Trunk Sewer
Project Overview
The project consists of replacing approximately 2.2 miles (11,700 linear feet) of trunk sewer main ranging in diameter from 18 to 21 inches, and of abandoning approximately 0.4 miles (2,240 linear feet) of existing 15-inch sewer mains. The work also includes replacement of 213 lineal feet of smaller tributary sewers. The only street affected by this project is Pomerado Road from Avenida Magnifica to the Interstate-15.
Elements of the USIU - Miramar Trunk Sewer project include: jack and bore tunneling under I-15 and Pomerado Road, installation of sewage bypass system(s) to maintain flow during construction, reconstruction of existing manholes, traffic control, installation of curb ramps, street resurfacing, and the replacement of landscaping and re-vegetation.
