Overview
Sewerage and Water Board of New Orleans operates a stormwater pump station in New Orleans, Louisiana, managing urban stormwater drainage to mitigate flooding in a low-lying coastal city.
The Sewerage and Water Board of New Orleans (SWBNO) operates a stormwater pump station located in New Orleans, Louisiana, United States. This facility is part of a comprehensive drainage system serving the metropolitan area, which relies on pumps and canals to remove stormwater from the city's below-sea-level terrain. As a major urban stormwater management asset, it handles significant volumes of runoff from rainfall events, protecting public safety and property. In the United States, stormwater pump stations like this one operate under the Clean Water Act and are often regulated through National Pollutant Discharge Elimination System (NPDES) permits, particularly for Municipal Separate Storm Sewer Systems (MS4). New Orleans is a Phase I large MS4 due to its population, requiring a comprehensive stormwater management program. The facility's design and operation focus on flood control, with pumps sized to handle intense rainfall typical of the Gulf Coast region. Environmentally, the station discharges stormwater into local water bodies such as Lake Pontchartrain or the Mississippi River, which are sensitive to pollutant loads from urban runoff. The SWBNO's drainage system is critical for preventing urban flooding, but also poses challenges for water quality management. The facility's role in conveying stormwater quickly away from populated areas helps reduce flood risk, but may also contribute to combined sewer overflows during heavy rains, a common issue in older cities like New Orleans.
Environmental context
New Orleans is a low-lying coastal city with a high water table and frequent heavy rainfall, making stormwater management critical. The city's drainage system discharges into Lake Pontchartrain and the Mississippi River, both of which are sensitive to urban runoff pollutants such as sediment, nutrients, and pathogens. The region's flat topography and subsidence increase flood risk, requiring robust pumping capacity. Regulatory oversight under the Clean Water Act and MS4 permits aims to control discharges to protect these water bodies.
Frequently asked questions
The stormwater pump station is located in New Orleans, Louisiana, United States, at coordinates 29.959756, -90.127630.
It pumps stormwater out of the city's drainage system to prevent flooding, operating as part of a network of pumps and canals that protect New Orleans from heavy rainfall.
The station removes stormwater from urban areas by pumping it into nearby water bodies like Lake Pontchartrain, reducing the risk of street and property flooding during rain events.
They are regulated under the Clean Water Act, often through NPDES MS4 permits, which require stormwater management programs to control pollution and manage runoff.
New Orleans is below sea level and prone to heavy rainfall, making effective stormwater pumping essential to prevent catastrophic flooding and protect public safety.
