These improvements <br />called for increasing the station's capacity and <br />were a condition of a development agreement <br />to construct a residential development in the <br />foothills of Yorba Linda. Psomas is designing <br />this project to YLWD specifications with funding <br />shared between BlackRock and the District. <br />This project consists of removing one 200-GPM <br />pump and pump can within an existing station, <br />and replacing it with an 1,800-GPM, VFD-driven <br />pump. In conjunction with this pump replacement <br />to improve fire -fighting capacity in this pressure <br />zone to be funded by the developer, the District <br />requested that Psomas also replace all existing, <br />outdated electrical and control equipment to be <br />installed in a new, separate electrical room, add <br />a gas -driven emergency generator, add a fence <br />around the perimeter of the site, and replace <br />a damaged meter vault and the meter within <br />the vault. All this work needs to be carefully <br />sequenced and scheduled within a limited <br />shutdown window to minimize downtime for the <br />pump station. <br />Sewer Rehabilitation <br />Rossmoor and Los Alamitos, CA <br />CLIENT CONTACT: Rossmoor/Los Alamitos Area <br />Sewer District <br />3243 Katella Avenue, Los Alamitos, CA <br />90720 1 Sarah Borbon, General Manager <br />562.431.2223 <br />YEAR COMPLETED: 2018 <br />KEY PERSONNEL: Maira Salcedo I Michael Swan <br />Benjamin Halbach <br />Psomas provided design of the sewer segment <br />rehabilitation in various locations in Rossmoor <br />and the City of Los Alamitos.
