New Orleans officials reported that 88 of 93 major drainage pumps are currently available for operation. This assessment follows a revision to the city's total count of major pumps from 99 to 93.
Why it matters
Maintaining functional drainage infrastructure is critical as the city prepares for incoming tropical weather this week. Regular reports on pump and power station status provide transparency regarding the city's flood mitigation readiness.
Eighty-eight of 93 major drainage pumps are currently available, with individual units offline at stations including DPS 6, 13, 14, and 18. Additionally, the Old Carrollton Underpass Station has three pumps out of service, though a temporary pump has been deployed.
The players
Carrollton Water Plant
This facility is a primary site for power conversion, utilizing frequency changers to support the city's drainage infrastructure.
The details
Several facilities face power-related challenges, including an electrical issue at the Carrollton Water Plant frequency changer and the permanent removal of Turbine 4. Frequency changers remain essential for the system, as they convert modern 60Hz power into the 25Hz power required by older drainage equipment.
