X Engineering prepared construction documents for the design of approximately 2700 linear feet of an 18" <br />domestic water line beneath a partially constructed roadway, Chino Avenue. The design included removal of <br />an existing 16" domestic water line and replacement with an 18" line. Additionally, removal of a connection <br />between the existing water line and a separate domestic water line within a different pressure zone was <br />required. The project team coordinated closely with the Ontario Municipal Utility Company (OMUC) to ensure <br />minimal water shut offs and to provide design solutions that would allow for future extension. <br />X Engineering prepared the design for two additional water lines within Chino Avenue which include a 12" <br />domestic water line and an 8" recycled water line. An alternative alignment study was also prepared and will <br />be presented to OMUC in an effort to find a feasible alignment for the two water lines. The preferred alignment <br />will minimize and avoid impacts to existing physical structures, eliminate the need for excess right-of-way <br />acquisition, and maintain compliance with the Division of Drinking Water requirements. <br />EX.
