Surrey city council approved a contract award of more than $10 million on Monday for Clearway Construction Inc. to install a trunk drainage main and replace 2,440 metres of aging and undersized drainage and sanitary sewers in Whalley, Guildford and Panorama.
With this, council has authorized $17,724,484.29 this month, for 5,340 metres of sanitary sewer work, with spending limits all together set at $19.5 million.
Concerning this latest contract before council, Surrey's general manager of engineering Scott Neuman recommended a $10,079,264.19 package, with a spending limit set at $11.1 million, in a corporate report that came before the politicians on Nov. 18.
The work is slated for Ellendale Drive (148 Street to Glen Avon Drive); 111A Avenue (Dumbarton Road to 148 Street); 111 Avenue (146 Street to 147A Street); 110A Avenue (146A Street to 147B Street); 110 Avenue (146 Street to 146A Street); 146A Street (110 Avenue to 111 Avenue); 147A Street (110A Avenue to 111A Avenue); 5439 144A Street/14428 Ridge Crescent Road (located within municipal right-of-way); and 122 Street (102A Avenue to the Metro Vancouver main).
The contract permits construction from 7 a.m. to 10 p.m., Monday through Friday, and is expected to start in December with completion by Spring 2026.
Meantime, council on Nov. 7 approved a $7.6 million contract to Complete Utility Contractors Ltd. for the construction of roughly 2,900 metres of sanitary sewer forcemains Creek and Quibble Creek.
This contract is for $7,645,220.10 with a spending limit set at $8,400,000. Neuman in a corporate report to council explained that sewage from parts of the City Centre and Newton flows south, conveyed through an aging trunk sewer paralleling Bear Creek.
Built in 1970, Neuman said, it's reached its capacity and is "experiencing surcharging during peak flows.
"With significant growth occurring in City Centre, Newton and the King George corridor, a sanitary sewer servicing strategy was developed and is intended to be constructed over the next 10 years," Neuman stated in his report. "The strategy includes two pump stations to convey flows north, alleviating the necessity to upsize the trunk sewer that is within the banks of Bear Creek."
Construction will be at 134 Street from 102 Avenue to 94A Avenue. Two pipes will be constructed in a shared trench, through Holland Park, which hosts events throughout the year. "We'd maintain local access and emergency access to the residents," Neuman said.
"The alignment of the forcemain within Holland Park will avoid impacts to trees and significant landscaping features and will be constructed during the winter months to avoid impacts to events planned within Holland Park," Neuman said.
Construction will begin in December, the Holland Park will be completed in the Spring and remaining work will be done by the end of Summer. Construction will take place from 7 a.m. to 10 p.m. Monday through Friday.
"A road closure along 134 Street will be required to facilitate construction. The road closure and works at major intersections will be scheduled during the summer months to minimize impacts to nearby schools and traffic," Neuman told council.
He explained the sewage from City Centre flows down to King George Boulevard and 94 Avenue, and sometimes is pumped back north but during other times in the day flows south through Bear Creek Park, where there's a trunk sewer along the creek system.
"That sewer does get surcharged (overloaded)," Neuman noted. "So this project will take relief off that sewer alongside the creek and continue to help support growth along the downtown core."
A trunk sewer system runs along Quibble Creek and Bear Creek. "It's actually located within the creek banks. I think it was build around 1970 by Metro Vancouver and downloaded to the City. That sewer takes all the flow from the northern part of the city and goes down towards Highway 10 into Metro Vancouver's trunk, so you can imagine all the growth from Newton, City Centre over the years has caused that sewer to be surcharged at capacity.
"So what we're looking a doing is adding a pump station on King George near Queen Elizabeth Secondary to pump the flows back north towards City Hall, and that will reduce flows from the Bear Creek sewer system," Neuman explained. "In about 10 years we'll need a second pump station around King George and 84 Avenue that will also pump back up through this system. "Between those two pump systems we won't have a need to going into Bear Creek and replace that aging sewer, we would likely reline it to minimize disturbance to the environment."
