As part of the Four Mile Run Pump Station upgrade, Alexandria Renew Enterprises (AlexRenew) will begin the reconstruction of two manholes next to Cora Kelly School in April.
To complete the reconstruction, AlexRenew must install an above-ground bypass line and pumping equipment that will be on-site for about six weeks. For safety purposes, the temporary pump and piping will be fenced off, and AlexRenew is working with the City of Alexandria to make sure construction does not inconvenience the school or sport activities.
Work on the Four Mile Run Pump Station upgrade began last summer next to Cora Kelly School for Math, Science and Technology and adjacent to Frank Mann Field at 3600 Commonwealth Ave. The Four Mile Pump Station, built in 1956, pushes wastewater toward AlexRenew’s facilities off Eisenhower Avenue to be cleaned. The pump station needed to be updated to improve electrical reliability, enhance odor control, and reduce the risk of sewer overflows. Work is scheduled to be completed early 2016.
Installation of the above ground bypass line and pumping equipment will largely be conducted between Monday and Friday from 7:00 am to 6:00 pm. Temporary safety fencing will be placed around the bypass pump and pipes and will be visible.
