North City Water Reclamation Plant Wastewater Upgrade Project
North City Water Reclamation Plant Wastewater Upgrade Project
Client: City of San Diego via CH2M
Location: San Diego, CA
Lopez Engineering, Inc. (LEI) served as a sub-contractor to CH2M, which had the prime contract with the City of San Diego. CH2M PM was Julian Hoyle and the key LEI personnel included John Lopez, PE, Donald Crawford, Martin Perea, Andrew Martins, Neil Sherer, Bela Wouters, and Wesley Breckenridge. LEI designed the electrical systems for the North City Water Reclamation Wastewater Upgrade project, which is a major part of the Clean Water Project being implemented by the City of San Diego.
This project replaced, modified, and added a significant part of the wastewater system. Due to its very large size, the project was subdivided into four packages, 1. Equalization, 2 Balance of Plant, 3. North City Pure Water Facility (NCPWF) Inlet Pump Station, and 4. Initial Site Package. LEI was initially responsible for all the electrical design for packages 1 through 3 and was responsible for coordinating with SDG&E for Package 4 and developed the initial single line diagram and substation layout for a new POC. As the project evolved, CH2M electrical engineers took over some of the facilities. For the co-generation, LEI helped coordinate meetings with SDG&E and equipment manufacturer representatives while CH2M took the lead for the electrical design for this project’s portion.
While the NCPWR Influent Pump Station and two new electrical rooms were new facilities with lighting and special systems requirements, the electrical systems represented the vast majority of LEI’s design effort.
