Project Title: Eastside Well Collector and Centralized Disinfection Facility Project 2. Lead Agency Name and Address: City of Pasadena, Water and Power Department (PWP), 150 South Los Robles Avenue, Suite 200, Pasadena, CA 91101 3. Contact Person and Phone Number: Elisa Ventura, P.E., Engineer, (626) 744-4465 4. Project Location: The proposed project consists of installing a disinfection facility at the City’s existing Jones Reservoir/Hamilton Park Site, which is located on the north side of Sierra Madre Boulevard between Riviera Drive and Hastings Ranch Road. The proposed Centralized Disinfection Facility would be located along the Sierra Madre Boulevard frontage east of and adjacent to existing PWP facilities (electric substation). The proposed Eastside Well Collector project consists of installing pipelines to connect seven well sites to the proposed Centralized Disinfection Facility. The proposed pipelines would be installed within the segments of the City’s existing street right of way identified in Table 1. Improvements would also be made at each of the involved seven well sites, which are identified in Table 2. Figure 1 depicts the regional orientation of the City of Pasadena. Figures 2-4 depict the locations of the proposed pipelines, the well sites, and the proposed disinfection facility.
